Description

TECHNICAL DATA SEARCH FOR CONVERTING TEXT FILE SEARCHED FOR ART DATA INTO MASTER TABLE FOR ART INFORMATION ANALYSIS}

The present invention relates to a method for automatically converting search data related to a patent or technical information into a master table for patent or technical information analysis, and more particularly, a patent obtained by using various patent search systems widely used at home and abroad. The present invention relates to a method of automatically converting search data for a patent information database called patent information analysis master table.

In today's industrial activities, the status of industrial property rights, such as patents and utility model rights, is increasingly important. Companies that have advanced patent rights have more possibilities to secure more favorable conditions in terms of technological competition and market development than those that do not. Therefore, the effective utilization of information on industrial property rights such as patent rights in corporate activities cannot be overemphasized.

Information on industrial property rights is used in various forms, and in particular, it is used as a powerful tool for avoiding duplication of research or overlapping investment. Information on industrial property rights can be obtained primarily through patent data retrieval systems. For example, you can access the homepage of each country's patent office or patent data retrieval service company and search for information using the patent data retrieval system provided by these institutions or through CD-ROM for patent data retrieval provided by commercial companies. Search is an example.

However, such search systems provide only data retrieval services and do not provide the more informative information that companies require. Secondary information such as duplicate research with existing patent rights, avoidance of duplicate investment, search or avoidance of infringement, and the degree and direction of R & D of competitors can only be obtained by analyzing and processing the above primary information.

Such secondary information can be obtained by a manual method in which a patent information analysis expert analyzes the retrieved data directly, but the efficiency is low. Therefore, it is more efficient to use a separate analysis system that processes and analyzes the searched data using the computer data processing function. The preliminary process for this is to database the search data. In other words, the search data obtained through the patent data search system can be text information and image information. Among them, the text data is converted into a database having a certain data structure, and a master table for analyzing patent data is constructed. Work should be a priority. It would be more useful to build master tables separately for each technical topic. Furthermore, if the master table contains not only patent data but also technical data obtained through various technical papers retrieval systems, its usefulness may be further enhanced.

The present invention is to meet the above requirements, the patent and technology having a certain data structure using a computer to the patent and technical information contained in various types of computer files obtained through various existing patent data or technical data retrieval systems Its purpose is to provide a data conversion method that automatically converts data from a master table for information analysis.

Furthermore, another object of the present invention is to provide a computer recording medium having a program recorded thereon that makes the above data conversion method executable on a computer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view illustrating a configuration of a system to which the data conversion method according to the present invention can be applied, and FIG. 3 is a patent / patent for accessing a technical data search CD-ROM or a computer accessed through computer communication / A diagram for explaining the concept of the present invention for constructing a master table for each technical topic using data retrieved from a technical data search system. 4 is a diagram illustrating a method of automatically converting a text file pre-stored in an auxiliary storage means into a master table by using the data conversion method according to the present invention.

In order to execute the data conversion method according to the present invention, in order to automatically convert the text file 310 downloaded from the patent / technical data search database 300 into the master table 320, at least the computer monitor 140, A conventional computer device having resources such as an auxiliary storage means 160 such as a hard disk, an input means 150 such as a keyboard and a mouse, and a central processing unit (CPU) 132 and a main memory 134, etc. in need. The computer device, computer communication to download the text file 310 from the patent / technical data retrieval system (100A, 100B) and the CD-ROM (100C) including a database for patent / technical data retrieval (300) It is convenient to have a CD-ROM driver 120 for driving the modem 110 and the CD-ROM 100C that make it possible.

In order to perform data conversion to the master table 320 according to the present invention using the computer apparatus illustrated in FIG. 1, first, a text file 310 that is a data conversion target using a patent / technical data search database 300. To download it should be stored in the auxiliary storage means (160). Accordingly, the retrieval systems 100A, 100B, and 100C, which are serviced through computer communication or CD-ROM, allow the text file 310 to be converted to include at least one or more records, and the record includes a plurality of field delimiters 404. A retrieval having a text file output function to be composed of field data 406 corresponding to these field delimiters 404 and to record the field delimiters 404 and field data 406 in a text file to be converted according to a predetermined rule. It must be a system. Examples of patent data retrieval system to which the present invention is applicable include QPAT, KIPRIS, PATROM Windows 5.0 version, and KINITI-IR Korea Patent Publication / Utility, in addition to the patent retrieval system of each country provided on the homepages of Korea, Japan, USA and European Patent Office. , PatentView CD, PAJ-CD, DACOM-DERWENT WPI, KINITI-IR WPI, Dialog DB (# 348, # 347, 351), IBM U.S. Patent Search System, etc. Examples of technical paper search systems include FSTA, MEDLINE, Food & Human Nutrition, KFRI-Literature Information, JOIS, COMPENDEX, SAE Paper. Information about the search system to which the present invention can be applied is provided at the bottom of the main menu screen shown in FIG. 7 to provide convenience to the user. The search system to which the present invention is applicable can be continuously added. On the other hand, the main menu screen shown in Figure 7, if the technical data search system is serviced on the Internet (internet web), the connection button 740 for connecting the user's computer directly to the homepage of the search system further Prepare.

Using these search systems, a user searches for patents / technical data for each technical subject and downloads a text file in advance, as shown in FIG. 3. For example, from the patent database A, patent data about DRAM is downloaded to a file S, and patent data about television are downloaded to a file B, respectively. In addition, the patent database (B) downloads the patent data on DRAM as a file (K), and the paper search data on television technology is downloaded to the file (A) from the technical data database (N). The downloaded files (A, B, K, S) should be stored in the auxiliary storage means (160).

The downloaded text files have various types of file structures according to the output functions of search systems, and the types or formats of the files are not limited to simple text files as long as the files can be opened to take the character information included therein. For example, the text file may have a hypertext file format. Therefore, in order to convert the data files of various file structures into the master table 320 of the same data structure, the file separators of the words or markers written in the text files are analyzed by analyzing the file structure of the text file for each search system. The record separator 402 and the field separator 404 must be defined in advance. Here, the file separator 408 should be a word or indicator that can uniquely represent the search system. For example, a text file downloaded using QPAT's U.S. patent search system contains the word "United States Patent" in one record and is not included in a text file downloaded by another search system. can do. As another example, the word "KUPA" may be used as a file separator in a text file downloaded using KINITI-IR's Korean Patent Publication System. Of course, the file delimiters in the above example may use other words or markers as long as the above conditions are met. The record includes field information related to one patent data, such as application number, date of application, priority number, priority date, name of invention, inventor, applicant, international patent classification, patent number, abstract, search word, claims, etc. Each of the field separators 404 is a pair of real data 406 recorded and paired with each other. These records include at least one of the records in one text file 310. In order to convert a plurality of records into record units, record separators 402 must be defined. The record separator 402 may use the file separator as the record separator when the file separator 408 is repeated in record units. Otherwise, the first field separator F1 may be used as the record separator. will be. Since the field separators 404 are recorded in pairs with the field data 406 in the text file 310, it may be easily defined by analyzing the text file.

The structure of the master table 320 can be the structure illustrated in "Table 1".

The data structure in "Table 1" is written comprehensively for the management, processing and analysis of more useful patent information, and this data structure may be changed as necessary.

Under the premise as described above, the data conversion method according to the present invention performs the data conversion based on the execution procedure shown in FIG. 7 to 12 show the screen configuration displayed on the monitor 140 for each step of data conversion.

First, a step of selecting a master table for each technical topic (S100) is performed. This is done in the main menu shown in FIG. That is, the user sets the name of the master table corresponding to the desired technical topic through the technical topic setting menu 700. Click on the technical topic setting menu 700 using the mouse to select an existing name or enter a new name. If an existing name is selected, the master table 320 corresponding to the name is opened from the auxiliary storage means 160. If a new name is entered, the master table having the data structure of "Table 1" is newly added to the auxiliary storage means. Create For example, if an existing master table named "EDLC" is set, the data contents of the "EDLC" master table are displayed in the master table window 710. The set master table is switched to an enabled state where data input or update is possible.

In this state, when the user clicks the "conversion file selection button" 730 provided at the bottom of the main menu with a mouse, a file selection window 800 for selecting a text file to be converted into data is displayed as shown in FIG. . The user selects a text file that has been previously downloaded and stored in the auxiliary storage means through the file selection window 800 and clicks the "open" button to execute the selected text file name (for example, PAJ01.txt) as shown in FIG. A confirmation window 900 for requesting confirmation of the user is displayed by displaying the name of the export search system (eg, PAJ-CD Japanese Patent) that outputs the file (S110).

When the user clicks the OK button of the confirmation window 900 with the mouse, the computer device finds the text file 400 selected by the user in the auxiliary storage means 160, opens the file, and parses the line unit from the beginning of the file. In step S120, the selected text file 400 is converted into a convertible file by performing the operation of searching for a file separator. For this inspection, the auxiliary storage means 160 must store a file separator list in which file separators of convertible files are stored in advance, or arrange the file separator list directly in the program. Consequently, the purpose of the above check can be achieved by comparing the words obtained by parsing line by line with the contents of the file separator table.

If the parsed words are not words recorded in the file separator list, a message is displayed indicating that data conversion is impossible and the execution of the program is terminated (S130).

However, if data conversion is possible, the conversion module corresponding to the type of text file 400 to be converted is enabled (S140). The conversion module is prepared for each search system. In other words, if the structure of the text file is different, data conversion is performed by using a separate conversion module. In the lower part of FIG. 7, a window 720 indicating "usable DB name", that is, a window indicating a list of search systems for downloading a text file capable of data conversion is provided, and a separate conversion for each search system listed in the list is provided. Have a module available.

The enabled conversion module opens the text file 400 again and parses it line by line, temporarily storing the field data 406 corresponding to one record in the array 410 set in the memory 134 ( S150). Here, temporary storage in the array is used as a way to improve the speed of importing data into the master table. It is also possible to skip the process of temporarily storing data in an array and import it directly into the master table. Since the master table has a database format, if the array is not utilized, the opening and closing of the master table must be repeated every time each field data is imported. As a result, the data processing speed may be slowed. Depending on the function of the effect may vary. The enabled conversion module first finds the record separator 408 from the contents of the parsed text file 400 and finds the beginning of the record. After continuing parsing, find the field delimiters (F1, F2, ..., Fi, ..) (404) and read the corresponding field data (FD1, FD2, ..., FDi, ..) Stored in the array 410. Thereafter, the data FD1, FD2, ..., FDi, ... for one record stored in the array 410 are imported into the master table 420 (S190).

The process from the storage to the import into the master table is repeated cyclically until the next record separator 409 is met unless the end of the file is met (S160, S190, S220, and S150 loops). Here, what is the record delimiter 408 and what is the field delimiter 404 among the parsed contents of the text file 400 uses the same method as the method of checking the constant file delimiter. That is, the record delimiter list and the field delimiter list are stored in the auxiliary storage means 160 in advance or each transformation module has information on it, and the parsed word is compared with the above information to find out whether the word is a record or a field delimiter. .

In order to add a duplicate record processing function that checks whether a record duplicated with a record stored in the array 410 exists in the master table 420 and performs a predetermined process according to the result, checking a record identifier (S160) and a file. The procedure (S170, S180, S190) may be performed between steps (S200) of checking whether the end of the test is met.

There are three ways to handle duplicate records. Firstly, duplicate records are not imported into the master table (skip mode). Secondly, duplicate records are imported into the master table. Is a method of merging the field data of the array corresponding to the field to the master table 420 only (integrated mode), and the third is a non-null overlap between the master table 420 and the array 410. If the field exists, there may be a method (replacement mode) in which the duplicate field data of the master table 420 is replaced with the duplicate field data of the array 410.

In order to implement these methods, a "merge" button 750 and a "replace" button 760 are provided at the lower end of the main menu shown in FIG. The user may alternatively select either the "merge" button 750 and the "replace" button 760, and the duplicated record is processed according to the selected scheme. If no button is selected, proceed to the first solution above. If record duplication is detected between the text file and the master table, and eventually between the records stored in the array and the master table, the "integrate" button 750 is a field that is null in the master table of the field data of the duplicate record in the text file. Specifies to merge only the field data corresponding to the master table. When the "replace" button 760 is selected, all field data of the duplicated records in the text file are imported into the corresponding fields of the master table to designate replacement of existing data in the master table.

5 is a diagram illustrating a concept of performing a merge of duplicate records when a duplicate record exists, and FIG. 6 is a diagram illustrating a concept of performing replacement of a duplicate record when a duplicate record exists. to be. 5 and 6, the master table 520 is first constructed using the text file downloaded through the patent database (A) 500, and then the same downloaded through the other patent database (B) 510. It is assumed that the contents of the master table 520 are to be updated by using a text file relating to the technical topic.

Here, if the user has selected the "merge" button 750, the conversion module checks this (S170), "notification number of the field data originating from the patent database (B) stored in the array 410 Field data are added to the corresponding record of the master table 520 (S190).

If the user has selected the "replace" button 760, the conversion module also checks this (S170), and among the field data obtained from the patent database (A) stored in the master table (620) Field data (for example, abstract (A)) overlapping with data of the patent database (B) is replaced with field data (for example, abstract (A ')) of the patent database (B) (S190). Therefore, after the replacement of the master table 630, the data contents of the "application number" and the "claim" are obtained from the patent database A, and the "green" data is obtained from the patent database B. FIG.

On the other hand, if the user has not selected any of the "merge" button 750 and the "replace" button 760, the array is reset to lose the temporarily stored data (S180), the end of the file While checking whether (S200) is met, a procedure of reparsing field data of the next record and storing the data in an array is performed (S150).

On the other hand, even if the procedure of temporarily storing data in the array is omitted, the above-described duplicate record processing is possible. In other words, by comparing the key field data of a specific record found while parsing a line in a text file and the key field data stored in the master table, the two groups can be checked for equality. The processing of the record in which the duplication is confirmed, that is, the skip mode, the merge mode, and the replace mode, depends on the setting conditions by the user as mentioned above.

If this is the case, when the merge mode is selected, only field data corresponding to a null field in the master table among the field records of the duplicated records in the text file are merged into the master table. In the replacement mode, all field data of duplicate records in the text file are imported into the corresponding fields of the master table to replace the existing data of the master table. If none of the merge button and the replace button is selected, a skip mode is entered. Thus, records of duplicate text files are discarded without being imported into the master table.

The data conversion process (S150 through S200) by the enabled conversion module is repeatedly executed for each record unit until the end of the text file 400 is met. When the end of the text file 400 is encountered during the parsing operation, the result of data conversion is displayed on the monitor as shown in FIG. 10 (S210). That is, information on the name of the text file to be converted, the name of the search system which downloaded the text file, the number of converted records and the number of records in which duplicates have occurred are reported. 10 illustrates a case where no duplication occurs. If data conversion has already been performed on the text file which has already been converted, the entire record will be duplicated. In this case, FIG. In case the user wants to know specific information about the duplicated record, the application number list of the duplicated record and the like are additionally displayed on the screen when the conversion file name is double-clicked on the screen of FIG. 11, which is illustrated in FIG. 12. .

The data conversion method as described above can be implemented by a computer program, for example, if it is recorded on a recording medium such as a CD-ROM, it will be possible to use it universally and conveniently. In addition, you can select the text files to be converted one at a time and convert the data as above, but you can also select multiple text files at once and convert each text file sequentially.

By using the data conversion method of the present invention as described above, it is possible to build a text file obtained by downloading the search results from a variety of patent or technical data search system to the same master table for each technology topic. Master tables built by technology topics can be enriched by updating them with additional data. Furthermore, since the master table is arranged in a certain data structure, it is easy to add a patent or technical information analysis function. For example, the master table can be conveniently used for preparing a patent map or extracting various statistical data.

Although the above has been described with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the present invention without departing from the spirit and scope of the invention described in the claims below. I can understand that you can.
