Description

  Embodiments of the present invention relate to a document management apparatus, a document management method, and a program.

In developed countries including Japan, maintenance and renewal of social infrastructure is a pressing, medium- and long-term, and ongoing issue. In particular, in Japan, where a depopulated society has arrived, tax revenue and infrastructure fee revenue will be lowered, and veteran engineers and field workers will be able to reap and restructure the social infrastructure that has been rapidly developed during the period of high growth. In light of the lack of human resources due to retirement, it is essential to make planned improvements and renewals for peaking the demand for renewal and securing the budget.
At that time, it is necessary to calculate the facility management such as repair / update and the resources for it, and to introduce asset management (asset management) to manage and manage in the long run, but the maintenance of the latest information of the facility is necessary Is necessary and very important.

  Generally, documents such as construction completion documents are delivered for each contractor and each construction. In order to maintain the latest information on facilities, it is continuously necessary to rearrange the documents systematically for each facility and facility and to replace the changed drawings resulting from the improvement and updating. However, these tasks are labor intensive, which can be a barrier to introducing and implementing asset management. In addition, there was a possibility that maintenance of the facility information itself could not be performed or asset information was not kept up-to-date because asset management was not introduced / implemented.

  Hereinafter, a document management apparatus, a document management method, and a program according to an embodiment will be described with reference to the drawings.

In a social infrastructure system premised on long-term use, it is necessary to maintain and manage facility information of the system over a long period of time while reflecting change information associated with repair or improvement update performed as needed. The document in which the facility information is described is mostly composed of a plurality of (for example, several tens to several hundreds) sheets (pages) with the same document number. Such a document has a remarkable feature that it is necessary to replace it in units of one drawing while maintaining the change contents with the change management number each time repair or improvement and update, and maintain and manage it over a long period like equipment. is there. When a change occurs, the change control number is increased, but this action is often used in a conventional expression such as rev-up.
These documents include those that can be completed in one sheet, such as outline drawings, but if changes are made after repairs or improvements are made, change management is performed each time and replacement is performed in units of one sheet. It is essentially the same as managing multiple documents.

In the case of a single item product (standard item) or the like assuming mass production, the document that describes the product information may be that the product is still being used regardless of whether the product is in production or discontinued. In view of the fact that the drawing itself is left. Therefore, it does not treat in the state of "the use abolition".
On the other hand, in the case of a social infrastructure system designed, manufactured, installed, and adjusted as a so-called one-article, for example, when a certain facility is completely renewed, the facility is removed and discarded. In such a case, it is necessary to reflect in the facility information that the equipment has been removed and is not currently used. Therefore, it is also a remarkable feature that the drawing describing the information of the equipment is in the state of “discontinued”.

  The "deprecated" document is basically not used. However, if you do not explicitly manage "deprecated use", if documents exchange information with each other (this is called "calling" etc.) The document number will be described. Since this means that accurate information can not be obtained, the management of “discontinued” is a remarkable feature that other documents do not have.

  Because of these characteristics, from the standpoint of using documents, it is required to improve the convenience of using documents, such as collecting, organizing, classifying, replacing, and maintaining the latest information on documents. The Furthermore, there is also a demand for reducing the burden of human-related work associated with the systematic maintenance of documents, and eradicating maintenance errors such as substitution errors caused by accompanying human-related work.

This requires a document management system based on a document that receives documents for each work from different vendors, manages the documents, and maintains the facilities based on the information of the documents. .
In particular, it is a heavy burden to manage documents that need to be updated over the long term while continuously reflecting the same information, and that require maintenance as well as facilities for a long time. This is also a serious problem in social infrastructure systems such as water supply companies, for example. In addition, not only document management in social infrastructure systems, but also general document management, tasks such as collecting, organizing, classifying, replacing and maintaining the latest information of documents occur.

  The document management system according to the embodiment automates and reduces the management of the document from the viewpoint of the user of the document. In particular, in consideration of the remarkable characteristics of documents handled by social infrastructure, such as facilities that are delivered for each construction from different contractors and reflect maintenance, improvement and update information of facilities, as well as facilities are maintained over a long period of time However, it can also be applied to general document management.

FIG. 1 is a diagram showing an outline of the operation of the document management system.
In a document where certain rules are recognized in the description place, there is a certain correspondence between the description place and the attribute of the information. The document management system uses this correspondence to extract information from the document, and uses the extracted information to manage the document. Thus, the information described in the document and usable for managing the document is described as "management information". The medium of the document is arbitrary, and may be a paper document or an electronic document. An electronic document is data that can be handled by any application program. For example, it is data which can be edited or browsed by document editing software, spreadsheet software, computer graphic editing software, presentation software, file browsing software and the like.

  The document management system acquires data obtained by digitizing a document on a paper medium, data of a document recorded on a recording medium such as a CD (Compact Disc), data of a document attached to an e-mail, and the like. The document management system divides document data into unit electronic data. The unit electronic data is electronic data obtained by dividing a document into one sheet (one page), the smallest divisible unit, or a unit suitable for use, and is the smallest unit document data to be managed. The document management system generates and adds unique information (hereinafter referred to as “unique information”) for each unit electronic data, using the management information extracted from the document.

  The document management system determines the storage location of each unit electronic data based on the unique information, generates the determined storage location in the document storage device, and automatically stores the unit electronic data. A storage location of unit electronic data is a storage area represented by a path of a directory structure suitable for document management. When the unique information is changed, the document management system automatically changes the storage location of the unit electronic data.

  Also, the document management system automatically determines whether or not the document is the latest one by comparing the change management number (Rev) included in the unique information. The change management number indicates the number of times of document update (replacement). When the document management system determines that replacement by the latest document is necessary, it replaces the unit electronic data stored in the document storage device. In addition, the document management system adds information representing the abolition of use to the unit electronic data that has been abolished by replacement.

For example, as information used for selecting the document storage device 5, setting contents of attributes of a predetermined hierarchy or higher in the unique information (setting contents of hierarchy -1, combination of setting contents of hierarchy -1 and hierarchy 2, etc.) are used. be able to.

The document management system 1 performs the following processes (1) to (10).
(1) Information extraction processing using the correspondence between the attribute of information and the description place of the information.
The document acquisition unit 451 of the document management device 4 acquires document electronic data obtained by scanning a document to be managed. Note that the scan is not limited to a scan in which paper is scanned by the scan device 2 to generate electronic data. It includes everything from scanning to acquiring certain information at once, such as software-based screen shots and snapshots, or images taken by digital cameras (hereinafter referred to as “digital cameras”).

  There are certain rules for the attributes of the management information and the location of the management information, depending on the type of document. The information extraction unit 4551 of the document management device 4 uses the correspondence relationship between the attribute of the management information in the format learned in advance and the description place of the management information from the document electronic data acquired collectively by scanning. , Extract management information.

  For example, it is assumed that the information of the drawing number is described in the description place A. The information extraction unit 4551 extracts information from the description location A in the document electronic data acquired in a batch, when it is desired to extract the information of the diagram number from the document electronic data.

  Also, for example, the information extraction unit 4551 extracts a specific DEV-NO (device number) from the document electronic data to be managed. DEV-NO is information unique to each item such as an auxiliary relay, and is a combination of alphanumeric characters such as "52-SP1" or a hyphen. A certain rule is recognized in the description place of this DEV-NO (article). For example, in the case of the A4 horizontal development connection diagram, another page using the contacts of the auxiliary relay described in the figure is described in a fixed format on the lower side of the diagram. Then, the description place (area) of this auxiliary relay is designated in advance, and the information extraction unit 4551 selectively extracts information from the description place. The information extraction unit 4551 can extract DEV-NO and information of another page using the DEV-NO contact point of the auxiliary relay from the extracted information. As a result, the time required to scan a large number of drawings can be reduced, and since other page locations where contacts are used are known, erroneous information is not erroneously recognized. The extracted information is set as unique information.

(2) Processing of learning, accumulation, and prediction of correspondence between management information and its description place.
The learning processing unit 453 of the document management device 4 learns, from the scanned document, the correspondence between the management information to be extracted and the description place of the management information. This scan is referred to as a test scan. The learning processing unit 453 learns that the correspondence between the management information and the description location is the correspondence rule possessed by the document of this type, and stores it in the format storage unit 441. By learning the correspondence relationship, the unique information management unit 455 automatically uses the correspondence relationship between the management information and the description location to automatically manage the management information necessary for managing the document, regardless of the type of document. It will be possible to get in

  Specifically, the user designates an area by the input unit 31 of the auxiliary input device 3 on the image of the document subjected to the test scan, and inputs the attribute of the management information described in the area. The learning processing unit 453 of the document management device 4 learns the format of the document by creating a format correspondence table in which what kind of attribute management information is described in the described location designated by the area. .

  For example, the learning processing unit 453 has a diagram number at the bottom right of the drawing, Rev (change management number) at the bottom left of the drawing, and the drawing at a wide position according to the relative positional relationship of the description location of the management information Is a development connection diagram, and so on. Even in the development connection diagram, different drawing numbers will be generated if the created contractor or a division within the same contractor is different, so that drawing number rules can be incorporated to improve learning accuracy. The rule of drawing number is the rule of how to assign drawing number. For example, it is a rule that any letter of the drawing number is a number or an alphabetic character.

  Also, the learning processing unit 453 can calculate the center of gravity of the description place of each management information, and can learn the format based on the combination of the number of lines connecting the respective centers of gravity and information such as graphics formed by connecting lines. . For example, if there are three lines connecting the centers of gravity of each piece of management information, the figure formed by the lines connecting the centers of gravity of the places where each piece of management information is described will be triangles, and differences in triangles can be seen at the angles of each vertex. The format determination unit 452 determines whether the figure connecting the centers of gravity of the management information specified in the document electronic data to be managed is similar to the figure connecting the centers of management information indicated by the learned format. , Predict what kind of drawing a document is. In addition, even if there is a slight deviation of the angle at the time of scanning, when incorporating the fuzzy (fuzzy) judgment using the similarity of figures into the format judgment unit 452, when accumulating and predicting the data of the test scan. Accuracy can be improved. For example, the size of the figure is the figure connecting the center of gravity of the description place of each management information specified in the document electronic data to be managed and the figure connecting the center of gravity of the description place of each management information indicated by the learned format. And the angle of each vertex are within a predetermined range. In this case, the format determination unit 452 determines that the document electronic data is a drawing of the learned format.

  Further, the format determination unit 452 of the document management device 4 can also determine the format using the fact that the figures have similarities. That is, even if the size of the document electronic data to be managed is different from the size of the document electronic data used for the format learning, the format judging unit 452 determines that the figures connecting the centers of gravity of the management information description locations are the same type. , Judge that it is the same format. For example, the format determination unit 452 may connect the center of gravity of the description location of each management information specified in the document electronic data to be managed, and the graphic of connecting the center of gravity of the description location of each management information indicated by the learned format. Reduce or enlarge any of the If the deviation of each vertex of both figures after reduction or enlargement is within a predetermined range, the format determination unit 452 determines that the document electronic data is a drawing of the learned format. As a result, even if the scan size is A3 in the full-size copy scan and the scan size is different from A4 in the reduced copy scan, the format determination unit 452 can specify the format.

  In addition, the format determination unit 452 predicts which type (which format) the drawing is, even if the scan direction is not the correct direction, and improves the learning accuracy. For example, even if the scan direction is rotated by 90 degrees from the format learning time, the format determination unit 452 collates the document electronic data to be managed and the description location of the figure number in the learned format, or the like. Predict what kind of drawing it is. Therefore, the format determination unit 452 returns the document electronic data to be managed obtained by the scan in the correct direction to predict which type of drawing it is. For example, if the A4 horizontal drawing is scanned in A4 vertical, the format determination unit 452 rotates the document electronic data by 90 degrees so as to be in the original direction, and collates with the learned format. If the rotation angle is unknown, the format determination unit 452 may compare the learned electronic data with each of the 90 °, 180 °, and 270 ° rotated document data. In addition, the format determination unit 452 may predict the format by combining the utilization of graphic similarity and the rotation of document electronic data.

  Further, the format determination unit 452 may predict the format from the description pattern of the information described in the extraction information. For example, it is assumed that the character configuration of the figure number indicated by the learned format is numbers, alphabets, numbers, alphabets, numbers, numbers, numbers. If the description content of the extraction information read from the document electronic data to be managed is the same pattern as this, and the other extraction information also has the same pattern as the character configuration indicated by the learned format, the format determination unit 452 Predict to match the learned format.

  In addition, the user may not designate the area where the management information is described directly by inputting character information of the setting content of the management information (the attribute is known). The learning processing unit 453 of the document management device 4 obtains character information by using an optical character recognition technique on the test scan image. The learning processing unit 453 detects the input character information from the character information obtained from the test scan image, and extracts the described location of the detected character information. The learning processing unit 453 generates a format correspondence table using the extracted description place.

(3) Matching process between learned format and newly read document.
The format determination unit 452 of the document management device 4 indicates the correspondence between the “attribute of management information” indicated by the learned format and the “location of the management information”, and “management” in the document to be newly read. It is checked whether the correspondence between "for information" and "the place for describing the management information" matches. Matching is performed based on whether the number of description locations (that is, the number of management information that you want to extract) matches, and whether or not the coordinates of each description location are within a predetermined range. Match with the limit matching information. Moreover, you may introduce the marking figure which is a figure for the marking which encloses a description place as a means to prevent the error of collation and to improve the reliability of collation.

  The user uses the auxiliary input device 3 to indicate the place where the management information to be acquired is to be acquired in the newly read document electronic data to be managed, surrounded by a marking figure (area designation). The format judgment unit 452 of the document management device 4 treats the combination of the information contained in the marking figure as data for collation as a document format is characterized.

Examples of information possessed by a marking figure include the shape (length L × height H etc.) of the marking figure and the barycentric coordinates of the marking figure. Further, examples of the information possessed by the marking figure group include the number of marking figures, the relative relationship between the marking figures, and the like.
The format determination unit 452 of the document management device 4 lists the information possessed by the marking figures designated by the user and the information possessed by the marking figure groups, and uses the list as matching data. The format determination unit 452 collates the collating data with the information possessed by the marking pattern indicated by the learned format or the list of information possessed by the marking pattern group.

In addition, the format determination unit 452 may place the marking figure on a layer different from the original document electronic data so that it can be handled independently of the original electronic data. In addition, there is also a method of performing matching that makes use of matching or non-matching of image recognition.
Even when trying to match with the information of the marking figure placed on the same layer as the original image, the original image is also recognized together, and the matching can not be done correctly. In order to solve this, it is characterized in that a marking figure is used and the marking figure can be handled in a layer different from the original image.

(4) Process of assigning attribute to extraction information.
The learning processing unit 453 of the document management device 4 learns in advance the correspondence between the management information to be extracted from the document electronic data and the description place thereof by test scan. The attribute assignment unit 4552 responds to the extracted information by correlating the extracted information obtained from the unit electronic data with the attribute of the management information based on the correspondence between the learned management information and the described location. Give the attribute to
The division unit 454 generates unit electronic data by dividing document electronic data into units of one page, the smallest divisible unit, or units suitable for use. The process of giving an attribute to the extraction information by the attribute giving unit 4552 is a pre-processing process required for the unique information generation unit 4555 to generate unique information of each unit electronic data.

For example, if the place where certain information is described is the place where “figure number” is described in the learned format, the attribute adding unit 4552 uses the attribute “figure number” in the information extracted from this place. Give.
The attribute may be encrypted, encoded, or compressed (compression of the extracted information capacity) in advance, similarly to the extracted information. For example, based on a certain rule, encryption is performed as follows: attribute “machine name” → “xy23fg”. The encryption unit 4553 encrypts, encodes, or compresses extracted information, and the attributed extraction information generation unit 4554 adds an encrypted, encoded, or compressed attribute to the extracted information, Generate attribution extraction information.

(5) Encryption, encoding and compression of extraction information (compression of extraction information capacity).
When the document electronic data is data that can directly acquire character information, the information extraction unit 4551 of the document management device 4 acquires the character information in the area designated by the user. If the information acquired from the document electronic data is image information, the information extraction unit 4551 converts it into character information by optical character recognition. The encryption unit 4553 encrypts, encodes, or compresses (capacity reduction) the extraction information converted into character information according to a certain rule.

The encryption unit 4553 reversely converts (returns) the character information into a general character code such as JIS code, and encrypts the information into hexadecimal or binary information according to a unique encryption rule. A plurality of the unique encryption rules can be used in advance, and the encryption unit 4553 selects an encryption rule to be used randomly from among these, and encrypts character information according to the selected encryption rule. The encryption unit 4553 adds information representing the selected encryption rule to redundant bits in the unique information. This redundant bit is provided in the attributeization information in which the encrypted character information is set, but may be provided in another position in the unique information. When unique information is used, the encrypted information included in the unique information is decrypted using a decryption rule corresponding to the encryption rule represented by the redundant bits. The encryption unit 4553 may encrypt the non-attributed information. Further, information indicating which attributeized information / non-attributed information is encrypted may be set in the redundant bits.
By encrypting the unique information, it is possible to prevent immediately knowing important information such as which facility of which facility and so on, at which facility the document is leaked.

(6) Processing of generation of unique information for each unit electronic data and error detection by attribute information constituting the unique information.
The unique information generation unit 4555 of the document management device 4 generates unique information for each unit electronic data by combining the extracted information.
The unique information generation unit 4555 combines the attributes numbered as in hierarchy-1 and hierarchy-2 according to a certain rule. For example, the unique information generation unit 4555 extracts the extraction information to which the attribute is given, in the hierarchy -1 "customer name", hierarchy -2 "machine name", hierarchy -3 "equipment name", hierarchy -4 "drawing name", It combines in order of hierarchy-5 "figure number", hierarchy-6 "sheet number", and hierarchy-7 "Rev (change management number)". In this way, it is possible to systematically maintain the information on the attributes of the facility.
If the description contents of the management information of each attribute in the unit electronic data do not all match, the unique information does not overlap. Therefore, even if an error in converting scanned image information into text information is included, it is also possible to ensure accuracy by preventing confusion with a completely different drawing.

  The information extraction unit 4551 may normally perform error detection processing by utilizing the fact that continuous scanning is mostly performed when reading a document composed of a plurality of sheets. For example, it is assumed that unit electronic data having the attribute “figure number” and the description content of the extraction information “1A2B3456” is continuously acquired by associating the extraction information with the attribute. The information extraction unit 4551 has a high probability that the description content has an error when unit electronic data in which the figure number of the description content different from the other is obtained among the unit electronic data is mixed. Use to detect errors. The information extraction unit 4551 displays the detection of an error on the display unit 32 of the auxiliary input device 3 and prompts the input of the correct description content. In addition, the information extraction unit 4551 extracts the number of sheets from the table of contents of the document electronic data, and the possibility of an error when the number does not match the number of unit electronic data obtained by dividing the document electronic data into sheet units. It may be determined that there is The information extraction unit 4551 may cause the display unit 32 of the auxiliary input device 3 to display a message to prompt the user for confirmation.

  The above error detection concept can also be used to shorten the process of attribution. If it is known that the figure number of the document composed of a plurality of sheets is the same, the unique information generation unit 4555 generates the remaining attributeization information generated from the extraction information of the figure number acquired in the first page. It is also given as attributeization information to all pages. This improves the processing speed of attribute association. However, because there is a risk that different figure numbers are mixed, does the information extraction unit 4551 check that the extraction information of the attribute “page” obtained from each of the continuous unit electronic data has description contents in ascending order? You may perform auxiliary error detection processing, such as whether or not.

  In addition, as an error detection method or an automatic correction method of an error using the method, for example, information of "outside" may be automatically determined as an error. For example, with regard to the extraction information of the same attribute obtained from each successive unit electronic data, it is assumed that the description content matches the predetermined ratio or more. In this case, the attributed extraction information generation unit 4554 causes the display unit 32 of the auxiliary input device 3 to display unit electronic data from which extraction information of different description content is obtained and the extraction information thereof. The user determines whether the extracted information is correct, and if incorrect, inputs the correct content. The information extraction unit 4551 obtains the correct description content according to the input. Thereby, the final judgment is made by the human system, and the correct information is adopted as the specific information. In this way, a flexible system can be made in which human system judgment can be intervened.

(7) Method of giving specific information and deletion / change / addition processing of specific information.
The unique information addition unit 4556 newly adds the unique information to the document as a part of the information of the document from which the unique information is obtained. The assigned unique information can be deleted, changed or added. The reason why we are able to delete, change and add is, for example, in order to be able to reflect the change even if the jurisdiction is changed from the A entity to the B entity by the consolidation or disintegration of facilities, widening of area. It is.
Also, in recent years, consolidation and abolition of facilities and widening of the area have often been carried out, but before that time there was a case where the facility information was not accurate because the customer name and aircraft name changed. As a result, time may be wasted to obtain necessary information. Therefore, when a change occurs, the document management system 1 can reflect the change in the unique information. Similar changes may also be required for general documents, such as reordering.

  The automatic reflection of the unique information change is triggered by the input unit 31 of the auxiliary input device 3 having input an instruction to collectively convert “before change” to “after change”. At this time, the unique information changing unit 4558 does not refer to only the information to be converted, but performs multiple check by confirming where in the drawing the information to be converted is located. Therefore, it is possible to prevent the unintended portion from being converted.

  The unique information addition unit 4556 may apply unique information to the unit electronic data by applying the concept of the banknote watermarking technique. That is, another layer (layer) to which unique information is given is provided by utilizing the fact that it is computerized. Providing unique information to this other layer is equivalent to the fact that the watermark is included but invisible. When the number of layers of the original document electronic data is n, the unique information addition unit 4556 adds unique information to the n + 1-th or maximum number of layers.

  In addition, some application software capable of dividing, deleting, rearranging, combining, etc. PDF data has a function of attaching a comment or a figure described in text to the PDF. Based on the same concept as this, the unique information addition unit 4556 may add PDF data with encrypted unique information as a comment or a figure.

  In addition, the unique information addition unit 4556 may embed unique information represented by a combination of certain figures such as a two-dimensional barcode into unit electronic data such as PDF format. Alternatively, such unique information may be embedded in the document in advance when the drawing is created.

  In addition, the unique information addition unit 4556 may paste (write, embed) the unique information represented by the character information in a specific place of the unit electronic data such as PDF without encrypting it. At this time, by designating the text color as transparent, it may not be normally visible, but when the area is designated with the mouse, the text color may be reversed so that it can be viewed when necessary.

  In addition, the specific information addition unit 4556 may add a part of the specific information to the unit electronic data, which can be normally referred to or edited, and the other parts can not normally be referred to. In this way, it is possible to make it impossible to refer to the basic part of the unique information or the information that is too detailed, in general. In this manner, the unique information is hierarchized by the referenceable information and the non-referenceable information, and the convenience is improved.

  Further, attribute information is added by the attributed extraction information generation unit 4554 to the description content of the extraction information set in the unique information. Several variable (rewritable) bit areas are prepared in the attribute information, and based on an instruction input by the user through the auxiliary input device 3, numbering of the original attributes in the bit areas (hierarchy 1, hierarchy- It may be possible to assign numbering of a system different from 2). This rewritable bit enables sorting of unit electronic data to be performed using numbering of another system. Although sorting itself is possible using attributes from the beginning, in order to make a search by another system not included in the attributes from the beginning, and in order to give new attributes intentionally, Prepare a bit area. For example, the processing unit 45 of the document management device 4 arranges the list of unique information registered in the unique information storage unit 442 in the ascending order of the hierarchy -1, and further arranges the ascending order of the hierarchy -2 in the ascending order. It is displayed on the display unit 62 of the browsing device 6. The processing unit 45 arranges the list of specific information in the ascending order of the first numbered hierarchy using the numbering of another system, and further arranges the ascending order of the second numbered hierarchy in order to display the browsing apparatus It is displayed on the display unit 62 of FIG.

(8) Document storage location search, automatic storage, storage location automatic generation, and storage location change processing using unique information.
The document management device 4 and the document storage device 5 search for a storage location (for example, a folder) of the document, automatically store the storage location to be stored, automatically generate a storage location, and store the storage location based on the unique information given to the document. Make a change. The storage location may be changed by, for example, moving the storage location from the storage location A of the document storage device 5 to the storage location B or transferring the storage location to another document storage device 5. For example, movement may occur when specific information is changed because the jurisdiction has changed from machine A to machine B, or when the management method is changed. When transferring data to another document storage device 5, the storage capacity of the document storage device 5 of the transfer destination or the transfer source, change of the hard disk drive configuration, and the like are considered.

  The storage location information registration unit 4561 of the document management device 4 lists the IP address of the document storage device 5 and the storage location configuration in the document storage device 5 in advance, and stores the list in the storage location information storage unit 443. . After the unique information is added to the scanned new electronic document to be managed, the storage location determination unit 4562 is configured to store the document electronic data on the basis of the information of the storage location configuration list 5. Search for somewhere. The storage processing unit 4563 stores the document electronic data in the folder to be stored based on the search result.

  The storage location determination unit 4562 determines whether a new storage location is necessary from the unique information of the scanned document electronic data by comparing the setting content of the unique information with the list of storage location configurations. For example, when the storage location determination unit 4562 determines that the machine name not included in the storage location configuration list is included in the unique information, the document storage device creates a folder for storing the scanned document electronic data Indicate 5 The storage location generation unit 521 of the document storage device 5 creates a folder instructed by the document storage unit 51, and the storage execution unit 522 stores the electronic document data in the created folder.

  Also, the user uses the input unit 31 of the auxiliary input device 3 or the input unit 41 of the document management device 4 to reflect, in the unique information, a change in jurisdiction associated with consolidation or widening of facilities. The storage location change instruction unit 4564 of the document management device 4 changes the storage location of the document electronic data stored in the document storage device 5 based on the unique information in which the change is reflected, or another document storage device 5 Instruct to move to

  FIG. 11 is a diagram showing an example of changing the setting content of the unique information. In the same figure, the case where the airfield A is integrated with the airfield Y is shown. It is assumed that the folder of the directory structure shown in FIG. 9 is configured in the document storage unit 51 of the document storage device 5. For the unique information for which the user has set the attribute information "customer name: xxx company group" and "airfield: airfield A" by the auxiliary input device 3, the setting content of the attribute "airfield" is "airfield A" Enter the instruction to change from "apparatus Y" to. Thereby, the unique information changing unit 4558 of the document management apparatus 4 searches the unique information storage unit 442, and, for example, the attribute information "customer name: xxx company group" and "machine place: machine place A" are set. Identify the unique information, and read out the unit electronic data name associated with the unique information. Upon determining the storage location from the identified unique information, the unique information changing unit 4558 reads the IP address of the storage location from the storage location information storage unit 443. The unique information changing unit 4558 accesses the document storage device 5 based on the read IP address, and specifies unit electronic data to be changed in unique information based on the storage location and the unit electronic data name. The specific information changing unit 4558 rewrites the setting content of the attribute “machine field” of the unique information added to the specified unit electronic data from “machine field A” to “machine field Y”. Furthermore, the unique information changing unit 4558 rewrites the setting content of the attribute “machine place” of the unique information specified in the unique information storage unit 442 from “machine place A” to “machine place Y”. The figure shows an example in which the unique information shown in FIG. 7 is rewritten. In this case, the storage location change instruction unit 4564 displays the directory of the storage location of the unit electronic data whose specific information has been changed, from “XX corporate group / machine A / specification edition” Change to "Specification". If the directory of “company company / machine Y” is not generated in the document storage unit 51 of the document storage device 5 before changing the specific information, the directory “company ○ company / machine A / specification” is The storage location changes in the newly generated directory. Alternatively, the directory name may be changed from “XX company group / airfield A / specification edition” to “XX company group / airway Y / specification edition”. In addition, when a directory of “company company / machine Y” is generated in the document storage unit 51 before changing the unique information, the storage location is changed under the directory.

  Further, when the document storage device 5 of the storage destination is determined by the setting contents of the hierarchy-1 and the attribute-2, the setting contents of the attribute "machine field" of the unique information are rewritten as described above, and the document storage of the storage destination is stored. It is assumed that the device 5 is changed. The storage location change instruction unit 4564 of the document management device 4 instructs the document storage device 5 that has newly become a storage destination of unit electronic data to generate a directory for storing unit electronic data whose unique information has been changed. At the same time, the directory of the document storage device 5 currently storing the unit electronic data is notified. The document storage device 5 that has newly become the storage destination generates a directory based on an instruction from the document management device 4 and reads out the unit electronic data whose specific information has been changed from the document storage device 5 of the current storage destination. ,Store.

  FIG. 12 is a diagram showing an example of changing the hierarchy in the unique information. When the unit electronic data of the unique information shown in FIG. 7 is stored in the folder having the directory structure shown in FIG. 9, the user inputs the replacement of the unique information in the hierarchy -2 and the hierarchy -3 by the auxiliary input device 3. I suppose. The unique information changing unit 4558 reads the unit electronic data name associated with the unique information from the unique information storage unit 442. Further, when the unique information changing unit 4558 determines the storage location from the unique information, the unique information changing unit 4558 reads the IP address of the storage location from the storage location information storage unit 443. The unique information changing unit 4558 accesses the document storage device 5 based on the read IP address, and specifies unit electronic data to be changed in unique information based on the storage location and the unit electronic data name. The unique information changing unit 4558 performs a change of replacing the attributeization information of the hierarchy-2 and the attributeization information of the hierarchy-3 with the specific information added to the specified unit electronic data. Further, the unique information changing unit 4558 changes the attribute information of layer-2 and the attribute information of layer-3 to the unique information of FIG. 7 stored in the unique information storage unit 442. The storage location change instruction unit 4564 is a folder directory of the storage location of the unit electronic data whose specific information has been modified, from “XX corporate group / machine spot A / specification version” to “xxx corporate group / specification version / machine location A Change to ".

(9) Automatic replacement of documents using unique information, automatic check processing after replacement.
The document management device 4 and the document storage device 5 perform automatic replacement of unit electronic data and automatic check after replacement. Automatic substitution is performed using unique information of the unit electronic data.

  The replacement determination unit 4565 of the document management device 4 compares the unique information generated for the unit electronic data of the newly read document electronic data with the unique information registered in the unique information storage unit 442. If there is one in which the generated unique information and the Rev or the serial number other than the unique information registered in the unique information storage unit 442 all match but only the Rev or the serial number differs among the unique information registered in the unique information storage unit 442 Make unit electronic data of serial number the latest. The replacement unit 523 of the document storage device 5 discards (or saves to the temporary save location) the unit electronic data of the old Rev or serial number stored in the document storage unit 51, and replaces it with the latest unit electronic data.

  FIG. 13 is a diagram showing an example of replacement of a document. When unit electronic data of the specific information shown in FIG. 7 is stored in the folder of the directory structure shown in FIG. 9, the unit electronic data of the document electronic data of the management object newly read by the document management apparatus 4 It is assumed that the unique information shown in 13 is generated. The replacement determination unit 4565 has already generated in the unique information storage unit 442 the generated unique information and other unique information that differs only in Rev, and the registered unique information has a smaller value of Rev. To detect. The replacement determination unit 4565 replaces the unit electronic data for which the registered unique information is obtained with the unit electronic data of the document electronic data that has been newly read. The replacement determination unit 4565 adds information indicating the removal of use to the unit electronic data that has been removed from use by replacement. The information indicating this use termination may be set as the unique information. Further, the replacement determination unit 4565 adds or sets information indicating the abolition of use to the unique information of the unit electronic data which is stored in the unique information storage unit 442 and has been abolished.

The replacement confirmation unit 524 of the document storage device 5 compares the number of replaced unit electronic data (the unit electronic data inserted as the latest page into the original document) with the number of replaced unit electronic data. It may also be checked if there is a replacement leak. Further, the replacement confirmation unit 524 may count the number of sheets newly added, though not replacement, and check whether there is a replacement leak.
In addition, when the Rev of each page is described in the table of contents of the document, the replacement confirmation unit 524 makes a difference depending on whether or not the same Rev as the table of contents is set as the unique information of the unit electronic data of the replaced page. It may be determined whether the replacement has been successfully performed.

(10) Information provision processing using unique information.
The unique information may include additional information. As a result, when the user accesses a document (in any medium, including electronic photographs), provision of additional information from the unique information given to the document is made, provided that the conditions set in advance are satisfied. Can receive

  The drawing is given a date, which is represented by a date, on a sign such as creation, survey, approval. Therefore, the information extraction unit 4551 of the document management device 4 extracts this date from the document electronic data, and the unique information management unit 455 sets the extracted date as unique information. The notification unit 457 of the document management device 4 outputs a message after a predetermined period of time, starting from the date indicated by the unique information stored in the unique information storage unit 442. For example, when the notification unit 457 detects that the recommended time for equipment update has come based on the date indicated by the unique information, it reads a message such as “The update time is approaching. Please prepare an update plan” It is output to a computer terminal connected to the device 6 or the external network 9 and displayed.

  Also, when creating a document, in order to automatically provide information in advance, unique information including a date of manufacture and a sales office contact is added. The processing unit 63 of the browsing device 6 pops up the date of manufacture and the sales office contact by reading the unique information from the unit electronic data being displayed.

  In addition, as described above, the unique information addition unit 4556 of the document management device 4 adds unique information represented by a combination of certain graphics, such as a two-dimensional barcode and an AR code, to the drawing. The unique information generation unit 4555 includes the URL of the service center in the unique information. The processing unit 63 of the browsing device 6 reads the unique information and displays the URL of the service center on the display unit 62. When the user inputs an access instruction to the URL of the service center through the input unit 61, the processing unit 63 displays the website of the URL on the display unit 62. This website allows the user to obtain relevant information. Instead of the viewing device 6, another device may be used. For example, instead of the browsing device 6, a smartphone can be used.

  Also, when the inspection information is embedded in the electronic chip attached to the device, the data read from the electronic chip is notified to the document management device 4, and the unique information generation unit 4555 draws the received data. It may be included in the specific information of the document electronic data such as an inspection report. The unique information is attached to unit electronic data by, for example, a two-dimensional barcode. The user reads the unique information described in the unit electronic data printed by the printing apparatus 7 using a smartphone or the like, and the inspection data is displayed. The user can inspect the on-site equipment while viewing the displayed inspection data. This enables integrated management of inspection data chips attached to drawings, inspection reports, and devices.

  Subsequently, an operation example of the document management system 1 will be described. In this operation example, the document management system 1 performs (1) document acquisition processing, (2) format learning processing, (3) unique information management processing, (4) document DB automatic generation processing, and (5) automatic replacement of documents. Processing, (6) Automatic check processing after document replacement is performed. Details of each process are shown below. In the following description, there are processes in which a plurality of operation examples different in application, method, and the like are described, but they can be combined as appropriate.

FIG. 14 is a flowchart showing document acquisition processing in the document management system 1.
When the document is digitized (step S105: electronic data), the document acquisition unit 451 of the document management device 4 acquires the digitized document. When the document electronic data is recorded on a computer readable recording medium such as CD or DVD (Digital Versatile Disc), the document acquiring unit 451 acquires the document electronic data read by the reading unit 43 from the recording medium. ,save. When the electronic document data is stored in various computer devices or recording media connected via the network 8, the document acquisition unit 451 receives the electronic document data via the network 8 and stores the electronic data. When the document electronic data is acquired via the external network 9 such as being attached to an electronic mail, the document acquisition unit 451 receives the document electronic data acquired via the external network 9 from the network 8 and stores it. .

  The document acquisition unit 451 determines whether the document electronic data is in an editable state (step S110). When the document acquisition unit 451 determines that the document electronic data is not in an editable state such as PDF format (step S110: NO), the document acquisition unit 451 stores the acquired document electronic data (step S115).

When the document acquisition unit 451 determines that the document electronic data is in an editable state by the document editing software, the spreadsheet software, the computer graphic editing software, etc. (step S110: YES), the document acquiring unit 451 performs the process of step S120. That is, the document acquisition unit 451 soft scans the acquired document electronic data and converts it into electronic data in a non-editable state (step S120). For soft scan, for example, snapshots can be used. In addition, conversion to PDF format or the like can be used as conversion to non-editable electronic data. The document acquisition unit 451 stores the electronic document data converted into the non-editable state (step S115).
In the case where character information can be directly extracted from document electronic data in an editable state, the document acquisition unit 451 may omit the soft scan in step S120 and save.

  On the other hand, when the medium of the document is paper (step S105: paper), the scanning device 2 scans and digitizes the document, and creates document electronic data (step S125). The document electronic data is, for example, non-editable PDF format data, but may be any other data format. The scanning device 2 sends the generated document electronic data to the document management device 4 (step S130). The document acquisition unit 451 of the document management device 4 stores the electronic document data received from the scanning device 2 via the network 8 (step S115).

After the process of step S115, the format determination unit 452 collates the electronic data stored in the document acquisition unit 451 with the learned format (step S135).
Therefore, first, the user designates the description place of each management information in the document electronic data by the input unit 31 of the auxiliary input device 3. For example, the user may designate by designating the area by surrounding the description place with the mouse, and designate the description place by designating the previously prepared marking figure and the reading position using the marking figure. You may When using a marking figure, the document management apparatus 4 prepares in advance a plurality of marking figures having different shapes and sizes.

  The format determination unit 452 determines whether or not the correspondence between the management information in the document electronic data and the description location thereof matches the correspondence information of the attribute information and the description location set in the format correspondence table. Check the The correspondence between the management information and the description place is that the information of the attribute A is described in the description place P1, the information of the attribute B is described in the description place P2, and so on. More specifically, the information of the attribute "customer name" is described above the center of the document, and the information of the attribute "figure number" is described on the lower right of the document, and so on.

  For collation, the format determination unit 452 converts the described place of each management information designated in the document electronic data into coordinates. The format determination unit 452 collates the coordinates of each piece of management information with the coordinates indicated by the description location of each attribute set in the format correspondence table in the format storage unit 441. The data used for this collation is described as collation data. For example, the coordinates of the position of the center of gravity of each described place (marking figure) can be used as the comparison data. If the difference between the collation data obtained from the document electronic data and the collation data acquired from the format correspondence table is within a predetermined range, the format judging unit 452 judges that the collation is successful.

  If the number of description places acquired from the document electronic data is different from the number of description places acquired from the format correspondence table, the format determination unit 452 does not match the learned format even if the information description places match. I judge that there is. For example, it is assumed that three description information attribute registration locations are registered in the format correspondence table. There are four places where the management information obtained from the electronic data is described, and even if three of them correspond to the places set in the format correspondence table, the number of places does not match, The format determination unit 452 determines that the format does not match the learned format. Alternatively, if the number of description places does not match even if the description place of each management information corresponds to the description place of each information, the format determination unit 452 indicates that effect on the display unit 42 or the auxiliary input. It may be displayed on the display unit 32 of the device 3 for notification, and human-body judgment may be interposed. The user uses the input unit 31 to input the determination result as to whether the format of the document electronic data matches the learned format.

  In addition, as a collation method, there are the following methods other than using the coordinates of the center of gravity of the described place as the collation data as described above.

(A) In addition to the comparison of the coordinates of the description place described above, the format determination unit 452 uses the shape (a rectangle of length L × height H, etc.) of each marking figure as data for comparison. In this case, in the format correspondence table, the information of the marking figure is set in association with the description place of each attribute. In addition, the format determination unit 452 adds the image of the marking figure designated by the user to the image of the document electronic data. When the document electronic data is data obtained by superposing image data of a plurality of layers (layers), the format determination unit 452 places the image data of the input marking figure on the image data of the original document electronic data. Change and add layers. As a result, the image data of the marking figure can be handled as a figure of a layer different from the original image data, and the shape of the figure, the number, the barycentric coordinates from the origin, the relative positional relationship of the figure is independent of the original image data It can be handled by

(B) When the document creation source is different, the description pattern used for each management information may be different. Therefore, in addition to the comparison of the coordinates of the description place described above, the format determination unit 452 also uses the description pattern of the management information in the marking figure as the comparison data. In this case, in the format correspondence table, the information pattern of the management information is set in association with the description place of each attribute. In the description pattern, for example, when the figure number is mixed alphanumeric characters such as "8K1G0001-sh002", what letter is alphabetic, what letter is after all letters, what letter is "-(hyphen ), The total number of characters, etc.

(C) In the process of electronic data conversion, there are cases where scanning is performed to different image sizes such as reduction and enlargement, scanning upside down, scanning upside down, and scanning with oblique inclination. Therefore, the format determination unit 452 corrects the coordinates of the management information by appropriately scaling, rotating or inverting the document electronic data, or finely adjusting the angle from the outer frame line and the outer frame angle of the document. . The format determination unit 452 uses the coordinates of the corrected management information as data for comparison to increase reliability so that no erroneous determination occurs in comparison.

The format determination unit 452 collates, one by one, the collation data obtained from the document electronic data with each of the collation data obtained from the format correspondence table of each learned format, and searches for a matching format correspondence table. .
The matching procedure may be performed as follows. That is, the data pattern for matching is stored in the format storage unit 441 in association with the format correspondence table for each document. The data pattern for verification includes the shape of each marking figure, the number of marking figures, the barycentric coordinates of each marking figure, the information pattern in each marking figure area, and the relative positional relationship of each marking figure. It is a combination of data. The format determination unit 452 specifies a similar one to the collation data pattern obtained from the document electronic data among the collation data patterns stored in the format storage unit 441. The format determination unit 452 performs the above-described matching process from the format correspondence table associated with the identified data pattern for matching. This improves the matching speed.

  The format determination unit 452 determines whether or not the collation with the learned format has succeeded in the collation processing in step S135 (step S140). If the format determination unit 452 determines that the matching is not successful with any of the format correspondence tables and does not match the learned format (step S140: NO), the learning processing unit 453 performs the format learning illustrated in FIG. A process is performed (step S145). After the format learning process, the unique information management unit 455 performs a unique information management process shown in FIG. 16 described later (step S150).

  If the format determination unit 452 determines that the collation with any of the format correspondence tables is successful and matches the learned format (step S140: YES), the unique information management unit 455 determines the unique information shown in FIG. 16 described later. An information management process is performed (step S155).

  If it is determined by the user that the document electronic data is in the learned format, the processes in steps S135 to S145 may not be performed. That is, the user uses the input unit 31 of the auxiliary input device 3 to select a format correspondence table that matches the document electronic data. The document management system 1 performs unique information management processing shown in FIG. 16 described later. By extracting management information from the description location based on the format correspondence table, the attribute of the extracted management information is uniquely determined.

FIG. 15 is a flowchart showing the format learning process in the document management system 1. In the format learning process, format generation, learning, accumulation, and prediction are performed.
The learning processing unit 453 of the document management device 4 performs a test scan to generate a format correspondence table of the document electronic data (step S205). That is, the learning processing unit 453 scans a document used for learning the format to obtain image data. When the format learning process is performed in step S145 of FIG. 14, the learning processing unit 453 may use the document electronic data stored in step S115. The user uses the input unit 31 of the auxiliary input device 3 to specify the description location of the management information in the image data scanned for a test. The learning processing unit 453 extracts the features of the specified description place (step S210). For example, the learning processing unit 453 extracts the coordinates of the designated description place as a feature, extracts the feature from the relationship of the relative place of each description place, etc., obtains the description pattern of the information in the description place, etc. . In addition, when the description place is specified by the marking figure, the used marking figure is characterized.

  The learning processing unit 453 determines similarity with the learned format by collating the feature of the description place extracted in step S210 with the feature of the description place obtained from the format correspondence table of each document (step S215). . The collation method can be arbitrary. For example, the learning processing unit 453 determines that the format correspondence table in which the number of description places specified in step S210 is the same or within a predetermined difference is similar. Alternatively, the learning processing unit 453 may connect the figure obtained by connecting the centers of gravity of the description places designated in step S210 with the figure obtained by connecting the centers of gravity of the description places set in the format correspondence table. You may judge from similarity. The learning processing unit 453 may further use the comparison result of the feature pattern obtained from the test-scanned image data and the feature pattern of the learned format for the similarity determination. As a feature pattern, a data pattern for matching or a description pattern can be used.

  The learning processing unit 453 determines whether there is a similar learned format (step S220). When the learning processing unit 453 detects a format correspondence table in which the features of the described place are similar, the learning processing unit 453 determines that there is a similar learned format (step S220: YES). The learning processing unit 453 reads out a format correspondence table of a learned format similar to the format (unknown format) of the document subjected to the test scan (step S225). The learning processing unit 453 generates a format correspondence table having the same setting contents as the read out format correspondence table, and displays the format correspondence table on the display unit 32 of the auxiliary input device 3 (step S230). The user uses the input unit 31 to input the complement of the missing information, the deletion of the unnecessary information, and the change of the non-matching information to the displayed format correspondence table (step S235). The learning processing unit 453 of the document management device 4 receives the information input from the auxiliary input device 3. The learning processing unit 453 changes the format correspondence table generated in step S230 based on the received information, and generates a format correspondence table of unknown format (step S250).

  On the other hand, when the learning processing unit 453 does not detect a format correspondence table in which the features of the description place are similar, the learning processing unit 453 determines that there is no similar learned format (step S220: NO). The auxiliary input device 3 transmits, to the document management device 4, the information entry place of the management information input by the user via the input unit 31 and the attribute of the management information set in the entry place. The learning processing unit 453 of the document management device 4 receives the description location and the attribute corresponding to the description location from the auxiliary input device 3 (steps S240 and S245). The description location may be information for selecting which description location specified in the test scan. The learning processing unit 453 generates a format correspondence table of unknown format in which the description place and the attribute corresponding to the description place are set (step S250).

  The learning processing unit 453 stores the format correspondence table of the unknown format generated in step S250 (step S255). The unique information management unit 455 performs unique information management processing shown in FIG. 16 (step S260). The learning processing unit 453 stores the generated format correspondence table of the unknown format in the format storage unit 441 regardless of the presence or absence of similarity with the learned format, and performs DB conversion such as construction / addition change of the format correspondence table. (Step S265).

  After converting the format correspondence table into a DB, the learning processing unit 453 extracts the feature pattern of the format, and stores it in the format storage unit 441 in association with the format correspondence table added in step S265. The format storage unit 441 performs DB conversion (construction / additional change) of the feature pattern (step S270).

  Note that the DB of the format correspondence table and the DB of the feature pattern of the format feature may be independent as separate DBs.

FIG. 16 is a flowchart showing unique information management processing in the document management system. In the unique information management process, generation of unique information, assignment of unique information to unit electronic data, change of unique information, and update of a unique information DB are performed.
The attribute assignment unit 4552 of the document management device 4 reads out from the format storage unit 441 the format correspondence table of the learned format for which the collation has succeeded in step S135 of FIG. 14 (step S305). If the matching with the learned format is not successful, the attribute assignment unit 4552 reads the format correspondence table generated in the process of step S145 from the format storage unit 441.

  The dividing unit 454 divides the document electronic data stored in step S115 of FIG. 14 into unit electronic data, and assigns a serial number (step S310). The unit of division is one page unit, the smallest unit that can be divided, or a unit suitable for use. The serial number is used to enable unique information to be assigned to each unit electronic data. This will make it possible to make the best use of unique information.

  The information extraction unit 4551 acquires extraction information from the described location indicated by the format correspondence table read out in step S305. The attribute assignment unit 4552 stores information indicating the correspondence between the extraction information and the attribute acquired by the information extraction unit 4551. The attribute assignment unit 4552 performs the process of the following steps S315 to S335 for each unit electronic data, for each of the attributes set in the format correspondence table read out in step S305.

For example, if the division unit of the document having one meaning of 10 pages into unit electronic data of one page is one page, it is divided into unit electronic data of 10 pages. If there are five pieces of management information to be extracted per page (five attributes), 10 [page] × 5 [management information / page] = 50 [management information]. Therefore, the unique information management unit 455 performs the process of steps S315 to S335 for 50 times.
In the following, the process of steps S315 to S335 for the i-th management information (i is an integer of 1 to 50 in the above example) will be referred to as steps S315-i to S335-i.

  In the format correspondence table, the attribute of the management information and the description location of the management information are listed. Further, the description table for management information (for example, the type and the number of characters of the characters constituting the document number) is associated with the format correspondence table. The attribute assignment unit 4552 reads out the attribute and the description location corresponding to the i-th management information set in the format correspondence table for which the matching is successful. The information extraction unit 4551 extracts image information from the description location corresponding to the i-th management information in the document electronic data, and the attribute assignment unit 4552 is an attribute corresponding to the i-th management information in the extracted image information (Step S315-i).

  For example, the image information extracted by the information extraction unit 4551 from the description places (x1, y1) to (x2, y2) in the electronic data is only extracted information from the description places at that time. However, “place of description” and “attribute of management information of the place of description” (for example, catalog number, product name handled by catalog, quote number, quote item, quote item price, quote total price, design document number, According to the correspondence relationship with the page, the inspection record, the inspection date, the inspection item, the inspection result, and the like, the attribute is associated with the extraction information from the description place.

  If the extraction information obtained in step S315-i is image information, the information extraction unit 4551 converts the image information into character information by optical character recognition (OCR) (step S320-i). When the extraction information can be directly acquired as character information, the information extraction unit 4551 can omit the process of converting the image information into character information. The information extraction unit 4551 obtains the result of converting the extraction information into character information (step S325-i). The case where the extraction information can be directly acquired as character information is, for example, a case where electronic data can be edited by document editing software, spreadsheet software, computer graphic editing software or the like.

The encryption unit 4553 encrypts the extraction information converted into character information and the character information indicating the attribute of the extraction information (step S330-i). For example, the encryption unit 4553 performs binary conversion on extraction information converted into character information. The attribute extraction information generation unit 4554 generates a set of encrypted extraction information and its attribute as attribute extraction information in order to prevent the extraction information from becoming unknown to what attribute information it is. (Step S335-i). The attribute extraction information is the meaning of the information that has been attributed and the extracted information subjected to attribute, and the generation method thereof is not limited. The attribute extraction information is used as attribute information to generate unique information.
The process of treating the extraction information and the attribute thereof as one set may be performed at the time of “extraction of information from the description place” or at the time of “characterization of extraction information” before performing encryption or the like.

  After the processes of steps S335-1 to S335-n, the unique information generation unit 4555 groups the attribute extraction extraction information for each unit electronic data and treats it as a "attribute information group". The user uses the input unit 31 of the auxiliary input device 3 to input an unattributed information group for each unit electronic data. The unique information generation unit 4555 layerizes the attribute extraction information group and the non-attribute information for each unit electronic data (step S340). This is to determine the upper / lower hierarchy of each attribute in advance when performing automatic generation of document DB, storage location search, storage location automatic change, and the like. If it is a learned format, using the upper / lower hierarchy of each attribute input by the input unit 31 of the auxiliary input device 3 before, if it is a newly generated format, the input unit of the auxiliary input device 3 31. Enter the upper / lower hierarchy of each attribute. The unique information generation unit 4555 adds, for each unit electronic data, the attributeization information included in the attributeization information group and the unattributed information included in the non-attributed information group based on the upper / lower hierarchy of each attribute. Make it hierarchical.

  The unique information generation unit 4555 combines unique attributeized information groups and non-attributed information groups for each unit electronic data to generate unique information (step S345). The unique information addition unit 4556 adds unique information corresponding to the unit electronic data to each unit electronic data (step S350). There are various methods and modes for giving unique information. For example, the unique information addition unit 4556 is the same layer as the unit electronic data (the layer is a combination of unique information as it is (a combination of encrypted extracted information, for example, alphanumeric information such as “abcf2435”). Write in the margin of).

There are the following modes, for example, when giving unique information.
(A) Assign unique information as a combination of certain figures, such as a barcode, a two-dimensional barcode, an AR code, etc.
(B) The unique information represented by the combination of encrypted attribute extraction information is added as it is.

On the other hand, examples of the method of giving unique information include the following.
(A) Write unique information in the margin of the same layer of unit electronic data, etc.
(B) The unique information is described in a layer different from unit electronic data.
(C) Assign unique information as a file name of unit electronic data.
These methods can be used according to the features of the document format, and may be specified by the user.

Moreover, these can be combined suitably, as follows.
(A) The unique information is given to a layer other than unit electronic data in the form of a combination of certain figures such as a two-dimensional barcode.

(B) In the above (a), additional information and the like related to the unit electronic data to which the unique information is added is added to the unique information. The additional content is input by the user through the input unit 31 of the auxiliary input device 3. As a result, by reading the unique information described in the unit electronic data, it is used for a service in which additional information and the like related to the unit electronic data are provided. For example, even if goods similar to unit electronic data, option prices, etc. are not described in the unit electronic data, the URL of the site providing the information can be set as the unique information of the unit electronic data. . By activating a two-dimensional barcode / AR code shooting application such as a smartphone and shooting unique information given to unit electronic data, a URL to a service providing site providing the information is displayed. Thus, the unique information includes an address from which the information related to the document can be obtained.

(C) Another document in which unit electronic data to which the unique information is added to the unique information is called (for example, if the unit electronic data is the expanded connection diagram A, the call for signal exchange is Set the information related to the developed connection diagram B) and the single product specification / handling manual incorporated in the system. These pieces of information may be input by the auxiliary input device 3 or the input unit 41, and when described in unit electronic data, may be read out by designating an area in the unit electronic data. Thus, by reading the unique information added to the unit electronic data, it is used for a service that can refer to a document related to the unit electronic data. In addition to referring to other documents, it is also possible to provide a customer service center, sales representatives, contact points in case of trouble, etc., to make the business style smarter. While (b) above is for consumer and single item products, (c) is suitable for handling systems such as social infrastructure systems.

The unique information registration unit 4557 converts the unique information into a DB (step S355).
Therefore, first, the unique information registration unit 4557 gives names to unit electronic data. The unique information registration unit 4557 selects some accurate unit electronic data names from the attributeization information constituting the unique information, and combines them to generate a unit electronic data name. The unique information registration unit 4557 may use information obtained by processing the unique information or a part of the unique information to generate a unit electronic data name.

  For example, it is assumed that hierarchy-1 “equipment name: equipment A”, hierarchy-2 “document number: 1A2B3456”, and hierarchy-3 “page: 3” are included in the unique information of unit electronic data of the design drawing. In addition, the naming rule of the unit electronic data name is “(Setting contents of Layer-1) _ (1st, 3rd, 5th, 6th characters of setting contents of Layer-2) − (Setting contents of Layer-3)”. It is assumed that The unique information generation unit 4555 generates a unit electronic data name “equipment A_1234-3”. The unit electronic data name naming rule is input by the auxiliary input device 3 by the user in step S235 or step S245 of FIG. 15, for example, but may be input at another timing.

Next, the unique information registration unit 4557 acquires the serial number assigned to the unit electronic data in step S310. The unit electronic data is expected to increase in number because it is a unit of one page or the smallest unit that can be divided or a unit suitable for use. Therefore, for example, the division unit 454 sets the temporary date of document electronic data as the date, date, hour, minute, and second when scanning is performed. The dividing unit 454 gives, for example, a sequential number to unit electronic data divided from the document electronic data. The division unit 454 generates the serial number of the unit electronic data by adding “hyphen” and the unit electronic data number after the temporary name of the document electronic data from which the unit electronic data is obtained.
Unique information registration unit 4557 creates a list in which serial numbers of unit electronic data, unit electronic data names, and unique information are associated, and registers the list in unique information storage unit 442.
The document management system 1 performs the automatic replacement process of the document shown in FIG. 18 and the automatic check process after the replacement of the document shown in FIG. 19 (step S360).

When the change of the unique information is input by the input unit 31 of the auxiliary input device 3, the unique information change unit 4558 receives the contents of the change (step S365). The unique information changing unit 4558 changes the unique information added to the unit electronic data stored in the document storage device 5 and the unique information registered in the unique information storage unit 442 according to the input change content ( Step S360). The change of the specific information is input, for example, when there is a change of jurisdiction of the facility or is input in step S235 of FIG. 15, but may be input at another timing. Specifically, the unique information changing unit 4558 identifies the unique information registered in the unique information storage unit 442 based on the information identifying the unique information to be changed input by the user, and identifies the identified unique information. , Change according to the change content input by the user. Furthermore, the unique information changing unit 4558 generates a unit electronic data name based on the changed unique information. The unique information changing unit 4558 changes the unit electronic data name registered in the unique information storage unit 442 in association with the changed unique information according to the generated unit electronic data name. Upon determining the storage location from the unique information before the change, the unique information changing unit 4558 reads the IP address of the storage location from the storage location information storage unit 443. The unique information changing unit 4558 accesses the document storage device 5 based on the read IP address, and specifies the unit electronic data to be changed in the unique information based on the storage location and the unit electronic data name before the change. The unique information changing unit 4558 changes the unique information added to the specified unit electronic data according to the content of the change input by the user, and sets the unit electronic data name as the unit electronic data name after the change.
The document management system 1 performs the automatic replacement process of the document shown in FIG. 18 and the automatic check process after the replacement of the document shown in FIG. 19 (step S360).

FIG. 17 is a flowchart showing the document DB generation process in the document management system.
When a document is newly stored in the document storage device 5, a storage location (for example, a folder) of the document is not generated in the document storage unit 51 (step S405: NO). If the storage location determination unit 4562 determines that there is no storage location for a document to be stored newly with reference to the storage location information storage unit 443, it automatically creates a storage location based on the unique information of the unit electronic data. The number of document storage devices 5 is not limited to one, and there may be several. Since the document storage device 5 can be identified by an address on a network such as a LAN, the document storage device 5 storing the document is specified by this address. Which document storage device 5 to use is determined according to the setting contents of the attributeization information or the non-attributed information set in the unique information. For example, it is determined which of the document storage devices 5-1 to 5-n is to be used according to the setting contents of the attribute of the hierarchy -1. The storage location determination unit 4562 generates a construction command of the storage location of the document (step S410).

  The specific information is composed of the attributeization information and the non-attributed information, and these are hierarchized as described above. Therefore, the storage location determination unit 4562 generates a storage location construction command based on this relationship. For example, in the specific information, hierarchy-1 "machine floor: machine space A", hierarchy-2 "equipment: equipment B", hierarchy-3 "drawing name: summary", hierarchy-4 "drawing number: A1B23456", hierarchy-5 It is assumed that the information of "(blank): (blank)" is included. In addition, it is assumed that the determination rule of the storage location configuration is “layer-1 / layer-2 / layer-3 / layer-4 / layer-5”. In this case, the storage location determination unit 4562 sets “machine area A / equipment B / outline version / A1B23456 / (blank)” as the storage location.

  The storage processing unit 4563 transmits the generated storage location construction command to the document storage device 5 (step S415). When receiving the storage location construction command (step S420), the storage location generation unit 521 of the document storage device 5 generates a storage location in the document storage unit 51 based on the received storage location construction command (step S425).

  If the document storage unit 51 stores a document storage location in the document storage unit 51 (step S405: YES), or after the process of step S425, the document storage device 5 performs the process of step S430. That is, the storage location configuration notification unit 527 of the document storage device 5 transmits the address and storage location configuration of the own device on the network to the document management device 4 (step S430). This transmission is performed regularly.

  The storage location information registration unit 4561 of the document management device 4 receives the address and storage location configuration from the document storage device 5 and stores the address and the storage location configuration (step S435). The storage location information registration unit 4561 generates a storage location table in which the received address is associated with the storage location configuration (step S440). The storage location information registration unit 4561 registers the generated storage location table in the storage location DB 433 and converts it into a DB (step S445).

  The document management system 1 searches and automatically saves a document storage location. Therefore, the storage location management unit 456 of the document management apparatus 4 searches the storage location of the document electronic data (unit electronic data) with reference to the unique information DB 432 and the storage location DB 433 (step S450). That is, the storage location determination unit 4562 reads out the unique information from the unique information storage unit 442, and identifies the storage location from the unique information in accordance with the storage location configuration determination rule. The storage location determination unit 4562 determines whether the storage location is registered in the storage location information storage unit 443 (step S455).

  If it is determined that the storage location is not registered (step S455: NO), the storage location determination unit 4562 executes the processing from step S410 to generate a storage location. On the other hand, when determining that the storage location is registered (step S455: YES), the storage location determination unit 4562 reads out the address corresponding to the storage location from the storage location information storage unit 443 (step S460). The storage processing unit 4563 transmits the unit electronic data to which the read unique information is added to the document storage device 5 of the read address, and instructs storage (step S465). The storage execution unit 522 of the document storage device 5 receives the electronic document data from the document management device 4 (step S470), and stores it in the designated storage location in the document storage unit 51 (step S475).

  The processing unit 63 of the browsing device 6 reads the document electronic data from the document storage device 5 and displays it on the display unit 62, and the printing device 7 reads the document electronic data from the document storage device 5 and prints it (step S480).

  Even after creating the storage location in the document storage device 5 for the first time, the document management device 4 searches the storage location of the electronic data by referring to the unique information DB 432 and the storage location DB 433 when reading the new document electronic data. Do. If there is no place to store even if the storage location is searched (for example, if it is a document with a new machine name) (step S455: NO), the document management system 1 passes through the above steps S410 to S450. The processing from step S455 is performed again.

The storage location can be changed automatically.
In addition, hierarchically structured attributes can be changed in their hierarchical structure even after being hierarchically formed. For example, the hierarchical relation in the hierarchical structure is such that "attributed information A is higher than attributeized information B" is reversed, and "attributed information B is higher than attributeized information A". Can be changed to By reflecting this change in the hierarchical structure, the structure of the storage location can be changed.
Alternatively, even if it is not necessary to change the hierarchical relationship in the hierarchical structure, if the extracted information corresponding to the attribute becomes old and it is necessary to update to a new information, the attribute should be updated collectively. Can. These changes are made from the auxiliary input device 3, and the changed contents are reflected in the unique information DB 432 by the unique information changing unit 4558.

FIG. 18 is a flow chart showing an automatic replacement process of a document in the document management system 1.
The replacement determination unit 4565 of the document management device 4 determines the necessity of replacement by the newly read document electronic data (step S505). When the document management apparatus 4 newly reads document electronic data from the outside, unique information is added to each unit electronic data by the process of FIG. 16 and unique information is registered in the unique information DB 432. At that time, for example, it is assumed that unique information in which only the change management number (Rev) does not match and other attributed information matches is already registered in the unique information storage unit 442. In this case, the replacement determination unit 4565 determines that the unit electronic data stored in the document storage unit 51 of the document storage device 5 is older, and the unit electronic data obtained from the newly read document electronic data is newer. Therefore, it is determined that a substitution is necessary.

If the replacement determination unit 4565 determines that replacement is not necessary according to the replacement necessity determination process of step S505 (step S510: NO), the document management system 1 starts the process of FIG. On the other hand, when it is determined that substitution is necessary (step S510: YES), the substitution determination unit 4565 performs the processing of step S515. That is, the replacement determination unit 4565 temporarily saves the stored document to be replaced (unnecessary document), and outputs a series of processing instructions for executing replacement to new unit electronic data to the document storage device 5 ( Step S515). Specifically, the replacement determination unit 4565 determines the storage location of the new unit electronic data from the unique information according to the determination rule of the storage location configuration. The replacement determination unit 4565 reads the IP address corresponding to the storage location from the storage location information storage unit 443 and, in the document storage device 5 of the read out IP address, the unit electronic data name of the replaced document and the new unit electronic data , And outputs a replacement instruction in which the information of the storage location is set.
When the replacement section 523 of the document storage device 5 receives the replacement instruction, it temporarily saves the older unit electronic data to the storage area of the save data (step S520), and the newer unit electronic data is older. Is stored in the place where the data of (1) was stored (step S525). Thus, replacement is automatically performed.

  After performing replacement in step S525, the replacement confirmation unit 524 of the document storage device 5 performs an automatic check after replacement to confirm whether replacement has been correctly performed (step S530). The replacement confirmation unit 524 is a collection of unit electronic data after replacement of unit electronic data, and counts up the total number of pages of a document group (for example, a document composed of a plurality of sheets) forming one meaning, It is automatically checked whether substitution is performed correctly using the change control number described in the table of contents of the document group and the change control number of the newly stored unit electronic data.

If replacement check unit 524 determines that replacement has been performed correctly (step S535: NO), replacement check unit 524 deletes the older unit electronic data saved in step S525 (step S540). This deletion may be deletion from memory, or may be logical deletion such as adding data representing deletion to unique information or the like.
At this time, as information provision to the human system, the document management device 4 may cause the display unit 32 of the auxiliary input device 3 to display a message indicating that replacement is correctly completed. When the user confirms this message and inputs the execution of deletion, the older unit electronic data which has been evacuated may be deleted.
The document management system 1 performs a document DB generation process shown in FIG.

  On the other hand, if replacement check unit 524 determines that replacement has not been performed correctly (step S535: YES), it notifies that by displaying on display unit 32 of auxiliary input device 3 or the like. The document management system 1 performs the process from step S235 of FIG. For example, the user refers to the document storage device 5 from the auxiliary input device 3 and performs replacement of unit electronic data by manual operation.

  FIG. 19 is a flow chart showing an automatic check process after replacing a document in the document management system 1. In the automatic check process after replacement, the unique information change management and the change in the unique information DB 432 and the storage location DB 433 are reflected.

  The change detection unit 4559 of the document management device 4 periodically checks the state of the unique information DB of the unique information DB 432, and detects whether or not there is a change in the unique information (step S605). For example, when the hierarchical relation among the attributeization information is changed in operation, the user inputs the change by the input unit 31 of the auxiliary input device 3 in step S360 in FIG. Also, for example, although the jurisdiction of the facility A was the aircraft site A, in the case where the facility site B becomes a result of the consolidation of facilities, it is necessary to change the attribution information. The user inputs this change through the input unit 31 of the auxiliary input device 3 in step S360 in FIG. In step S365 in FIG. 16, the unique information changing unit 4558 changes the unique information based on this input.

When the change detection unit 4559 determines that no change occurs in the unique information (step S610: NO), the change detection unit 4559 performs the process of FIG. 17 described above. On the other hand, when the change detection unit 4559 determines that a change has occurred in the unique information (step S610: YES), the processing unit 45 reflects the change content in the unique information DB 432 and the storage location DB 433. That is, the document management system 1 performs the process from step S445 in FIG. 17 described above, and automatically changes the storage location.
A function may be provided to display information to automatically change the storage location on the display unit 42 of the document management device 4 or the display unit 32 of the auxiliary input device 3 and provide information to a human system.

  In the embodiment described above, the management information is extracted from the document to create the unique information, but in view of the use of the management information in the above embodiment and other embodiments, the unique information is generated at the time of document creation. You may give it a letter. For example, the unique information is given to the document as it is or in the form of a certain figure such as a two-dimensional barcode or AR code. When the document management device 4 takes in document electronic data, unique information has already been assigned. The document management device 4 does not execute the processing from the attributeization information generation to the unique information generation, directly acquires the assigned unique information, and registers the acquired unique information in the unique information DB 432.

  Further, the unique information generated by the document storage device 5 is added to the document in which the unique information is not described in advance at the time of document creation. In the attached specific information, related information other than the information originally contained in the document is related information (such as a document in which a signal link is described, a document in which an original specification is described, etc.) Information and additional information such as URL of service center are given. At the time of reference to this document, the user can receive a service utilizing the given unique information.

  Further, the specific information may incorporate related information indicating the degree of association between documents. For example, the document management apparatus 4 counts the number of times the information (such as the drawing number) of the document B has appeared in the document A. The document management device 4 sets the number of occurrences or a value obtained by converting the number of occurrences per unit page as the relevance. By utilizing this degree of association, it is possible to provide a support function such as displaying a pop-up display such as “There are following related drawings” on the display screen when referring to a document.

In addition, the document management system 1 may use unique information in the same manner as DB conversion to systematically list documents stored in the document storage unit 51 of the document storage device 5. For example, it is as stated above that maintenance of facility information becomes complicated as the water service provider receives the delivery of completed documents for each construction from a plurality of contractors, but if this embodiment is used, the burden will be greatly increased. It can be reduced.
Further, convenience may be improved such that the user can refer to a desired document simply by clicking on the desired document number in the document list.

In developed countries including Japan, maintenance and renewal of social infrastructure is a pressing, medium- and long-term, and ongoing issue. In particular, in Japan, where a depopulated society has arrived, in the redevelopment and rebuilding of social infrastructure that has been rapidly developed during the high growth period, the revenue from tax revenues and infrastructure fees that are the source of income declines and retirement of veteran staff and field workers In light of human resource shortages, it is essential to make planned improvements and renewals to smooth the peak of renewal demand and secure a budget.
At that time, it is effective to introduce asset management (asset management) that calculates facility management such as repair / update and resources for it, and it will be effective to introduce asset management (asset management) to manage and manage in the long run. You need to keep it.

However, documents such as construction completion documents are delivered for each contractor and each construction. It is continuously necessary to rearrange them systematically for each facility and equipment, and to replace the changed drawings resulting from improvements and updates. These efforts are a barrier to the introduction and implementation of asset management, and there is a problem that the maintenance of facility information itself is not performed or the latest information is not kept.
For example, in the water supply industry, particularly in small and medium-sized enterprises, there are many places where personnel information is insufficient due to the large retirement of baby boomers, and facility information is not sufficiently maintained. As a result, the introduction of asset management necessary to promote consolidation and expansion of facilities based on population decline has been delayed, and on the other hand, it is difficult to accept increases in water charges that cover shortages in toll revenues, which is a very serious problem. It has become.
The document management system 1 can reduce these efforts and keep facility information up to date. The document management system 1 is applicable not only to the management of documents such as books of social infrastructure but also to the management of other general documents.

  According to the above-described embodiment, it is possible to systematically rearrange the construction completion documents delivered for each construction company by construction company for each facility and equipment, and to replace the change books that occur due to improvements and updates. It becomes possible to automate maintenance of the reflected facility information. Therefore, there is an effect (advantage) in which the labor conventionally required for these can be significantly reduced. And this reduction in effort can eliminate the barrier to implementing asset management. Furthermore, according to the present embodiment, since human resource management work can be greatly reduced because asset management is automated, maintenance of facility information that accurately reflects the latest information can be performed promptly after completion of construction. It can be implemented accurately.

  As a result, it becomes possible to smooth the peak of renewal demand, which is the subject of social infrastructure redevelopment and reconstruction, and to make systematic improvements and renewals for securing budget, and maintain the function of sustainable social infrastructure for the future. And can contribute to improvement. This is due to the deterioration of social infrastructure in developed countries (for example, highway repair in the United States), rapid social infrastructure development in developing countries and emerging countries (for example, power infrastructure due to population explosion, water Also in the rapid development of infrastructure, it is an important matter in common in maintaining and improving the function of sustainable social infrastructure in the future.

In addition, in Japan where a depopulating society has arrived, in order to cope with the decreasing labor force, not only in the water supply industry but also in various industries, in order to pursue consolidation of facilities and systems and efficiency and convenience. It is necessary to promote the wide area system of Therefore, it is inevitable that the burden of book management will further increase as the scale and complexity of the system are increased by integrating separate systems into one.
Based on these things, the facility information management (book management) in a water supply enterprise is described below as a specific example of the advantage acquired by applying this embodiment.

  The water supply companies are carrying out operations such as maintenance of facilities, formulation of improvement and update plans, and ordering based on the information on construction completion documents delivered for each construction by supplier. In ordering, contractors differ for each type of facility (ordering category) such as civil engineering, architecture, machinery, electricity, and information communication. Also, focusing on electrical equipment, for example, as the same order classification, contractors often differ between A and B, and also due to intensifying market competition and the adoption of open systems in recent years, the same aircraft Even in the case of electrical equipment, there may be a mixture of multiple suppliers. Therefore, the management of the assets (equipment, system, etc.) owned by the water utility is extremely complicated.

  Furthermore, as measures to cope with the decrease in water supply volume and decrease in water rate income due to population decline, consolidation of facilities such as water treatment plants, distribution reservoirs and water stations, and management integration between water suppliers as a measure to reduce labor force Etc. will be promoted in the future. Therefore, there are many changes in facility names and jurisdictions, etc., and it is necessary to reflect these appropriately, and asset management (such as facilities and systems) held by the water supply business will further increase burdens. It will be forced.

  In addition, it is not limited to water supply companies, but social infrastructure facilities such as electricity, gas, water supply and sewerage are premised on long-term use. Repairs, improvements, and partial updates will be made as needed, but those change information will replace the changed drawings in the originally delivered book (eg, a developed connection diagram consisting of several tens to several hundreds). Therefore, it is necessary to maintain and manage for a long time while reflecting change information.

  From these things, by applying the document management system 1 of the embodiment, the effect (advantage) brought about by the reduction of labor of the facility information maintenance reflecting the latest information and the promptness and accuracy excluding human work is very large. . And the effect can be widely exhibited in other fields without limiting the object to the water supply business entity.

  Specific effects include the following. The document management system 1 assigns unique information to each unit of one document, or the smallest unit that can be divided, or a unit suitable for use. Therefore, it is possible to realize the functions of automatic generation, automatic search, automatic storage, automatic change of the storage location, automatic replacement by latest version management, and automatic check after replacement. Therefore, it is possible to reduce the complexity and effort of the document management described above, and to realize quick and accurate document management.

The object to be managed by the document management system 1 is not limited to a document such as a book of social infrastructure. In addition, a document refers to anything that contains information such as drawings, instruction manuals, repair and inspection reports, quotations, slips, flyers, catalogs, etc. The drawing of social infrastructure is only an example of a document .
Since the information possessed by the document and the location where the information is described has a certain correspondence or can be applied by finding the correspondence, the effect can be exerted on any document.

  Collecting, organizing, categorizing and replacing documents to keep up-to-date information is not an issue or problem that only document management created in social infrastructure has, but it is a document management of daily work in the general field And so on. Therefore, the effects of the present embodiment can be exhibited in the general field.

  For example, not only in the field of social infrastructure systems, but converting documents into electronic data for reasons of storage space reduction etc. is performed, but in the present embodiment, the unit of one document or the smallest unit that can be divided or Provide unique information for each unit of unit suitable for use. This makes it possible to apply the functions of automatic generation, automatic search, automatic storage, automatic change of storage place, automatic replacement by latest version management, automatic check after replacement, and the effects thereof. .

  In addition, in the application of specific information, apply techniques such as encryption (encoding, information compression, etc.) such as barcodes, AR codes, and two-dimensional barcodes, and conversion techniques such as character codes and binary processing, Information capacity can be secured. Therefore, the unique information can include various and many attribute information (for example, in the case of a catalog, products handled by the catalog, catalog number, manufacturer, date of issue, etc.), the application field and its range are very It can be said that it is wide.

  According to at least one embodiment described above, the document can be systematically stored in the document storage device by having the attribution unit and the document management unit.
