  The information processing system 10 according to the present embodiment is used for, for example, a conference support system capable of collectively using conference processing with high relevance such as a regular conference, and a program for realizing the conference support system on a computer. Applicable. The present invention can also be applied to applications such as a file archive system capable of collectively archiving highly relevant conference materials and a program for realizing the file archive system on a computer.

  Returning to FIG. 1, the information management server 100 is, for example, a personal computer or a workstation. The information management server 100 includes an interface unit (I / F) 102, a reception unit 104, a search unit 106, a calculation unit 108, an estimation unit 110, a presentation unit 112, a conference information storage device 150, and setting information. A storage device 170 and a related information storage device 180 are included.

  The interface unit 102 communicates with the user terminal device 20 and the file management server 40 via the network 3 and accesses the user information storage device 30.

  The conference information storage device 150 stores a conference information management table 156 as shown in FIG. The meeting information management table 156 includes, for each meeting, an ID that is identification information of the meeting, a meeting name, a meeting start date and time, a meeting room, a meeting ID of the previous (or next) meeting of a regular meeting or a related meeting, The ID of the conference participant, the ID of the conference material, and the ID of the registrant who registered the conference information are stored.

  In the present embodiment, the user information storage device 30 has the user information management table 32 and the file management server 40 has the material information management table 42 separately from the information management server 100. However, the present invention is not limited to this. The user information management table 32 and the material information management table 42 may be stored in a storage unit in the management server 100.

  The accepting unit 104 accepts an instruction from the user terminal device 20 via the interface unit 102. The search unit 106 accesses the conference information storage device 150, searches the conference material ID in response to an instruction from the reception unit 104, and passes the conference material ID to the presentation unit 112.

  The calculation unit 108 accesses the setting information storage device 170 and the relationship information storage device 180, acquires the conference information related to the conference information of an arbitrary conference, and determines the degree of relationship between the conference information for each relationship of the conference information. Is calculated based on a preset criterion.

  The setting information storage device 170 has attribute information for each object including conference information and information related to the conference, for example, information such as reference material of the conference material. In this embodiment, the degree of relationship shown in FIG. A storage unit (shown as “degree of relation” in the drawing) 172 and a coefficient storage unit (shown as “coefficient” in the drawing) 174 shown in FIG. 5B are provided. The degree of relation and the coefficient are values used by the calculation unit 108 to be described later, and can be changed as necessary. As illustrated in FIG. 5A, the relationship degree storage unit 172 stores a reference value of the relationship level for each relationship type that is an attribute indicating the relationship between conference information. The kind of object of this embodiment is an example, and is not limited to this.

  In the present embodiment, the higher the degree of relation, the higher the degree of relation. For example, the meeting information in the relation of “previous meeting” has the largest degree of relation “10” and “participation” is related. The degree “3”, “meeting material” are set in advance to the degree of relationship “2”, and the “reference material” is set in advance to the degree of relationship “2”. In the present embodiment, the conference information for calculating the degree of relationship is the previous conference, participation, conference material, and reference material, but is not limited thereto, and may include other conference information.

  As shown in FIG. 5B, the coefficient storage unit 174 stores a weighting coefficient for each hop count. In the present embodiment, for example, a coefficient “1” is applied to the degree of relation when the hop is traced from the base point information, and a coefficient “1/2” is multiplied to the degree of relation when the hop is traced two hops from the base point information. Each coefficient is stored so that the coefficient “1/4” is applied to the degree of relation when 3 hops are followed. As the number of hops increases, that is, when the relationship between conference information is viewed in order, the degree of relationship with the conference serving as a base point is considered to be small. Therefore, the degree of relationship is adjusted by a coefficient.

  Thus, in the present embodiment, the degree of relationship between conference information calculated by the calculation unit 108 can be adjusted by weighting according to the relationship between conferences.

  FIG. 6 is a diagram illustrating an example of the data structure of the relationship information management table 182 stored in the relationship information storage device 180. In this embodiment, the relationship information management table 182 has a conference ID and a reference material ID registered as relationship source objects, and related objects are associated as relationship destinations for each relationship source object. The relationship types are stored in association with each other as attributes indicating the relationship between these objects.

  As an example, a conference whose ID is “M001” is used as a relation source, and participants and conference materials are stored in the relation information management table 182 as information about the conference. And, as related parties, users with IDs “U001” and “U002” are stored with the relationship type “participation”, and the conference material with ID “F001” is related information management with the relationship type “conference material” It is stored in the table 182. Further, the material with ID “F001” is used as the relation source, the reference material is stored in the relation information management table 182 as information of this material, and the material with ID “F002” is the relation of “reference material” as the relation destination. It is stored in the relationship information management table 182 by type.

  The calculation unit 108 receives from the reception unit 104 an instruction for processing to estimate another conference related to a certain conference. Based on the conference, the relationship information management table 182 is referred to, the conference information of the related party and the relationship type are acquired, and further, the relationship storage unit 172 and the coefficient storage unit 174 are referred to, and the relationship storage unit 172 The degree of relation for each relation type is obtained from the coefficient, the coefficient “1” for the first hop is obtained from the coefficient storage unit 174, and the degree of relation is multiplied by the coefficient to calculate each degree of relation.

  The calculation unit 108 further obtains the conference information and the relationship type of the related party by referring to the related information management table 182 with the information that became the related destination at the first hop as a base point, and the degree of relationship The degree of relation is obtained from the storage unit 172, the coefficient “1/2” of the second hop is obtained from the coefficient storage unit 174, the degree of relation is multiplied by the coefficient, and each degree of relation is calculated. Is added to the relationship level.

  Further, the calculation unit 108 obtains the conference information and the relationship type of the related party by referring to the related information management table 182 with the information that became the related destination in the second hop as a base point, and the degree of relationship The degree of relation is obtained from the storage unit 172, the coefficient “1/4” of the third hop is obtained from the coefficient storage unit 174, the degree of relation is multiplied by the coefficient, and each degree of relation is calculated. Is added to the relationship level.

  The estimation unit 110 sums up the degree of relationship calculated for each meeting as a related party other than the meeting serving as the base point for estimation, and estimates that the higher the degree of relation, the higher the degree of relevance to the base point conference. . Moreover, in this embodiment, the estimation part 110 acquires the last meeting with reference to the related information management table 182, and notifies the presentation part 112 as a last meeting.

  As another example, the degree of relationship is calculated for each material in order to estimate other materials related to the material based on other conference information, for example, the material, instead of using the conference as a base point. You may estimate highly relevant materials.

  The presentation unit 112 provides information on various screens to the user terminal device 20 via the interface unit 102 in order to present conference information to be described later. Alternatively, the presentation unit 112 may display various screens on a display unit (not shown) of the information management server 100.

FIG. 7 is a flowchart showing an example of the operation of the information management server 100 of this embodiment.
The information management server 100 according to the present embodiment can realize the functions of the units 102 to 112 by the CPU of the information management server 100 executing a computer program installed in the memory of the information management server 100. . Hereinafter, a description will be given with reference to FIGS. 1 and 7.

  The computer program of the present embodiment includes a conference information storage device 150 that stores conference information related to a conference, and a relationship information storage device 180 that stores an attribute indicating the relationship between conference information in association with each other between conference information. To the computer (information management server 100) having the above, obtain the conference information related to the conference information of an arbitrary conference by referring to the relationship information storage device 180, and determine the degree of relationship between the conference information A calculation procedure (step S27) for calculating based on a criterion set in advance for each attribute, an estimation procedure (step S27) for estimating another conference highly relevant to an arbitrary conference based on the calculated degree of relationship, arbitrary It is described that the presentation procedure (step S29) for presenting another conference that is estimated to be highly relevant to this conference is executed.

  In the configuration as described above, a data processing method of the information management server 100 of this embodiment will be described below. Hereinafter, a description will be given with reference to FIGS. 1 and 7.

  The data processing method of the information management server 100 according to the present embodiment stores a conference information storage device 150 that stores conference information related to a conference, and an attribute indicating the relationship between the conference information in association with each relationship between the conference information. The information management server 100 having the relationship information storage device 180 refers to the relationship information storage device 180, acquires the conference information related to the conference information of an arbitrary conference, and determines the degree of relationship between the conference information, Calculation based on criteria set in advance for each attribute of the conference information (step S27), and based on the calculated degree of relationship, other conferences that are highly relevant to an arbitrary conference are estimated (step S27). Another conference that is estimated to be highly relevant to the conference is presented (step S29).

  The operation of the information management server 100 of this embodiment configured as described above will be described below. Hereinafter, description will be made with reference to FIGS. 1 and 6 to 9.

  First, in the present embodiment, a user of the user terminal device 20 starts up the system or accesses a website using a browser and performs a login operation to the information processing system 10 in the user terminal device 20. . In the information management server 100, information necessary for login from the user terminal device 20, for example, a user ID and password is received by the receiving unit 104 via the interface unit 102, and an authentication unit (not shown) performs user authentication processing. (Not shown).

  As a result, the initial screen 200 of FIG. 8 is displayed on the display unit of the user terminal device 20. The initial screen 200 includes a material list reference instruction column 202, a conference list reference instruction column 204, a conference new registration instruction column 206, a logout button 208, and a login status display unit 210. Here, an example is shown in which DEF with user ID U002 is logged in.

  The user can operate the document list reference instruction column 202, the conference list reference instruction column 204, the new conference registration instruction column 206, and the logout button 208 using the operation unit of the user terminal device 20. The operation when the user operates the conference list reference instruction column 204 and the conference new registration instruction column 206 on the initial screen 200 on the user terminal device 20 will be described later. Here, a case where the material list reference instruction column 202 on the initial screen 200 is operated will be described.

  In the present embodiment, when the material list reference instruction column 202 is operated, the reception unit 104 receives an instruction to refer to the conference material list (step S11). At this time, the user information of the user acquired in the above-described login authentication process is also received by the reception unit 104 and transferred to the search unit 106. Then, the search unit 106 accesses the conference information storage device 150 and searches for an ongoing conference related to the user (step S13). Here, the conference related to the user is a conference registered by the logged-in user or a conference in which the logged-in user is included in the participants. The search unit 106 searches for a conference related to the currently held user based on the logged-in user ID and the current time. The search date and time can be acquired from a clock (not shown) of the information management server 100.

  If there is an ongoing conference (YES in step S15), the search unit 106 refers to the conference information storage device 150 and searches for conference materials and reference materials for the conference (step S17). Further, the search unit 106 further acquires a processing title and a URI that is a storage location of the material from the material information management table 42 based on the retrieved meeting information and reference material information (ID). And the presentation part 112 displays the material list screen 220 as shown in FIG. 9 on the display part of the user terminal device 20 based on the acquired information (step S19). On the other hand, when there is no meeting being held (NO in step S15), the present process may be terminated or the initial screen 200 may be displayed again. Processing in the case where there is no ongoing conference will be described in an embodiment described later.

  As shown in FIG. 9, the material list screen 220 includes an ongoing conference display unit 222, a conference material display unit 224, a reference material display unit 226, and a related conference reference instruction button 228. In the conference material display unit 224 and the reference material display unit 226, a link to the material on which the character string of the material title is displayed is formed based on the URI.

  In the user terminal device 20, in order to select a material to be referred to by the user, a link of the material displayed on the ongoing conference display unit 222, the conference material display unit 224, or the reference material display unit 226 of the material list screen 220 is displayed. When operated, the user terminal device 20 can access the linked file, and the selected conference material is downloaded to the user terminal device 20 and displayed on the display unit. In the user terminal device 20, the downloaded conference material can be stored in the storage unit.

  Returning to FIG. 7, when the related meeting reference instruction button 228 is operated on the user terminal device 20 on the material list screen 220, the receiving unit 104 of the information management server 100 receives the material request instruction of the related meeting (in step S <b> 25). YES). The related conference reference instruction button 228 is operated when the user wants to refer to another related conference.

  Then, the calculation unit 108 is instructed by the reception unit 104, and the calculation unit 108 and the estimation unit 110 perform related conference estimation processing (step S27). This related meeting estimation process will be described later. By this related conference estimation process, a related conference is estimated, and the presentation unit 112 presents the result to the user terminal device 20 (step S29).

  As an example, the related conference list screen 240 illustrated in FIG. 10 is displayed on the display unit of the user terminal device 20. The related conference list screen 240 includes a previous conference display unit 242 and a related conference display unit 244. The previous meeting display unit 242 displays information on the previous meeting, and if the link is operated, the material of the previous meeting can be accessed. In addition, the related meeting display unit 244 displays information on related meeting materials, and when the link is operated, each related meeting material can be accessed. Here, it is preferable that the related conference materials are displayed in descending order of relevance. Moreover, you may show only the information which has the relevance degree more than predetermined | prescribed relevance among the estimated data.

Next, the flow of the related meeting estimation process in step S27 of FIG. 7 will be described. FIG. 11 is a flowchart illustrating an example of a procedure of related conference estimation processing according to the present embodiment.
First, the calculation unit 108 designates the ongoing conference searched by the search unit 106 as a base point (step S51). Then, the calculation unit 108 calculates the degree of relationship between the relationship source information and the relationship destination information of the first hop (step S53).

  Here, referring to the relationship information management table 182 in FIG. 6, the conference M001 is the relationship source, and the relationship destination information includes the participants U001 and U002, the conference material F001, and the next conference M004. Extracted. The degree of relationship of each information is acquired with reference to the degree-of-relation storage unit 172 (FIG. 5 (a)), and the coefficient storage unit 174 (FIG. 5 (b)) obtains the coefficient of the degree of relationship when one hop is followed from the base point. Get by reference. For example, the relationship level of the first hop participant U001 is 3 because the relationship type between the conference M001 and the participant U001 is “participation”. Since the conference M001 and the participant U001 are related by one hop, the coefficient of the degree of relationship in the number of hops is 1.

  As shown in FIG. 12, the degree of relationship between the first hop between the conference M001 and the participant U001 is “3 × 1 = 3”. Similarly, the first hop relationship between the conference M001 and the participant U002 is “3 × 1 = 3”, the first hop relationship between the conference M001 and the conference material F001 is “2 × 1 = 2”, and the conference M001 and the conference M004. The degree of relationship of the first hop is “10 × 1 = 10”.

  Next, the calculation unit 108 uses the relation destination information obtained at the first hop as the relation source information at the second hop, and refers to the relation information management table 182 in FIG. To do. Then, after calculating the degree of relation between the relation source information and the relation destination information when two hops are taken from the base point, the degree of relation with the first hop is added (step S55). At this time, with reference to the coefficient storage unit 174 in FIG. To calculate the degree of relationship for the second and subsequent hop objects, the path of the relationship is followed.

  For example, when calculating the degree of relationship between the conference M001 and the conference M003 at the second hop, there are two routes. The first route is a conference M001 to a participant U001 to a conference M003, and a second circuit is a conference M001 to a participant U002 to a conference M003. First, the degree of relationship in the first route is calculated. The degree of relationship in the route is 3 because the relationship type between the conference M001 and the participant U001 is “participation”.

  Since the relationship type between the participant U001 and the conference M003 is “participation”, the degree of relationship with respect to the relationship type is 3. Since the conference M001 and the conference M003 for calculating the degree of relation are related by two hops, the coefficient of the degree of relation in the number of hops is ½. Therefore, the degree of relationship of the second hop through the conference M001 to the participant U001 to the conference M003 in the conference M001 and the conference M003 is “3/2 + 3/2 = 3”. The degree of relationship up to the second hop calculated in this way is shown in FIG.

  Similarly, the calculation unit 108 refers to the relationship information management table 182 of FIG. 6 as the relationship source information when the relationship destination information obtained at the second hop is traced 3 hops from the base point. Extract the destination. Then, after calculating the degree of relationship between the relation source information of the third hop and the relation destination information, the degree of relation of the second hop is added (step S57). The degree of relationship up to the third hop calculated in this way is shown in FIG.

  Based on the degree of relationship calculated by the calculation unit 108 in this way, the estimation unit 110 adds up the degree of relationship from the base point to the third hop for each conference (step S59). For example, when the degree of relationship between the conference M001 and the conference M002 is calculated, as shown in FIG. 12, the total for each hop is “0 + 3 + 4 = 7”. Similarly, the degree of relationship between each object is calculated. However, in the present embodiment, the type of object to be calculated is only “conference”. As a result, as shown in FIG. 13, the degree of relationship of each conference with the conference M001 is obtained.

  Then, the estimation unit 110 rearranges the conferences according to the combined degree of relation (step S61). Then, the processing ends and returns to FIG. For example, in the present embodiment, the presentation unit 112 presents conference information of other conferences that are estimated to be highly relevant to an arbitrary conference based on the degree of relationship to the user in the order of high relevance.

  As described above, according to the information processing system 10 of the present embodiment, the relationship between the conference material and the conference, the participant, the reference material, and the like is managed in the related information storage device 180, and the calculation unit 108 uses the related information. By calculating the degree of relationship from the information stored in the storage device 180, the estimation unit 110 estimates a related conference. Further, by using the information stored in the relationship information storage device 180 in the search unit 106, a formula for determining materials related to the conference or materials related to the previous conference during or after the conference. Can find out.

  According to the information processing system 10 of the present embodiment, for example, by registering keywords and identification information in the conference material, it is not related to each other, but only by registering the conference information, the degree of relationship between the conference information And can estimate other related meetings and their information. As the conference information, for example, the conference information can be registered by a general-purpose scheduler or the like, and information necessary for transmitting the conference opening notification to the participants can be used. The user can divert the functions of the system without inputting information for diverting the system.

  According to the information processing system 10 of the present embodiment, highly relevant conference materials such as regular conferences can be used together. Since a conference highly related to the designated conference is estimated and presented, conference materials related to a certain conference can be easily found.
