Description

  The present invention relates to a technique for supporting analysis of access behaviors of a plurality of users for an object group such as a document converted into electronic data.

Various information sharing has been achieved by the development of information processing technology in recent years. As a typical example, a plurality of documents stored on a database or a network are associated in advance along a certain purpose, A system that allows a plurality of users to share access to the associated document group is known.
In such a document sharing system, for example, a document group is structured according to a user's document sharing behavior. When the document sharing system is operated in a company, a document group structure similar to an organization is set in advance and operated. Often done.

However, the user's work may be performed across the organization, and the document structure set in advance does not necessarily match the document structure that is formed later as the work progresses. There is a discrepancy between the scene and the structure of the documents.
Such divergence reduces the usability of shared documents and can be a hindrance to business progress. Therefore, it is difficult for administrators of document sharing systems and analysts of organizational activities to detect such divergence between the document group structure and business conditions. Therefore, it is important to optimize such as reducing the gap between the two.

This is registered in the document management system when the user specifies a position on the hierarchical structure or a position on the document title structure using a management system unique to the document management system such as a hierarchical structure or a title structure of the document group. There has been proposed an information collection system that can automatically collect existing information (see Patent Document 1).
In addition, an Internet profiling system has been proposed that automatically extracts and stores user interests and preferences based on the user's access history on a Web site, and enables queries of stored data in a query language (Patent) Reference 2).
JP 2004-86334 A JP 2001-142907 A

According to the proposal in Patent Document 1, since information can be automatically collected using the information hierarchical structure in the document management system, it is possible to grasp the usage status of the document throughout the document management system. Further, according to the proposal of Patent Document 2, it is possible to grasp the actual state of how each user uses a document group of a Web site. It becomes possible.
However, these conventional proposals have a problem that the document group structure cannot be compared with the actual business situation.

The present invention has been made in view of the above-described conventional circumstances, and provides support for analyzing object sharing behavior using access logs of a plurality of users for an object group in which a plurality of objects are associated in advance. It is aimed.
That is, the present invention uses the access logs of a plurality of users with respect to an object group in which a plurality of objects such as documents are associated in advance, and detects a difference between the structure of the object group and a user's actual work, and the difference between the two is detected. The purpose is to present hints for optimization such as reduction.

  The present invention is a technique for performing support for analyzing an object sharing action using access logs of a plurality of users for an object group in which a plurality of objects are associated in advance, and performs object sharing processing. The present invention is realized in various modes such as a behavior analysis support device, a program that configures the object sharing behavior analysis support device with a computer, and a method that is implemented by the object sharing behavior analysis support device.

  A typical example of an object is a document (data), but the present invention can also be used for analysis of various shared information such as Web site, conference room reservation application data, and information service usage data. The object shared log data acquisition means that can be described later acquires user access log information to the document group according to the object to be applied, acquires user access log information to the website, and reserves conference rooms by the user. What is necessary is just to acquire log information and the information service utilization log information by the user. Since a Web site generally has a directed graph structure similar to an example of the present invention by a hyperlink, this may be used. In addition, the reservation application data of the conference room is usually managed by a data model in which various reservation contents are structured. For example, recently, it is managed by XML having a tree structure. Can be treated as The information service usage data and the like are also the same as the conference room reservation application data.

In the object sharing behavior analysis support device according to one aspect of the present invention, the object sharing log data acquisition unit acquires the association structure information of the object group and the user access log information, and the object sharing behavior range diagram generation unit acquires the information. Based on the information, information on the specified target user and information on other users who have accessed the object having the same identity as the object accessed by the target user, and the relationship of the plurality of objects having the same identity An object sharing action range diagram including an association structure is generated, and the object sharing action range diagram generated by the object sharing action range diagram presenting means is visualized and presented on a screen display or print output.
Here, as a typical example of the present invention, the object group has a structure in which a plurality of objects are associated in advance with an upper and lower relationship,
The object sharing action range diagram generating means generates an object sharing action range diagram including an association structure of an object group obtained by tracing the relationship between a plurality of objects having the same identity.

  Therefore, other users who have accessed an object having the same identity as the target user and the association structure of these object groups can be presented as an object sharing action range diagram, which allows the analyst to, for example, Can give an indication of whether or not the organization has an appropriate structure in accordance with the actual situation of business, and if not, what should be corrected.

  Here, the object having the identity may be an object having a relationship that is set in advance and intended to be regarded as the same, in addition to the same object. In addition, a plurality of documents stored in the same file may be handled as having the same identity.

In the present invention, an object sharing log data acquisition unit may be configured with an object sharing system that manages an object group in which a plurality of objects are associated in advance and manages access logs of a plurality of users for the object group. The object group association structure information and user access log information may be acquired from the object sharing system.
In the present invention, the target user may be set in advance as a monitoring target, but an object sharing action that accepts an operation on an object sharing action range diagram including the designation of the target user from an operator (for example, an analyst). Range diagram operating means may be provided.

The present invention further includes an object sharing action statistic calculating unit that calculates a predetermined statistic relating to a user or an object based on information acquired by the object sharing log data acquiring unit, and the object sharing action range diagram generating unit includes the object sharing action range diagram generating unit. An object sharing action range diagram including the calculated statistics may be generated, and the object sharing action range diagram including the statistics may be visualized and presented.
The present invention also includes an organization information management means for holding organization information composed of a plurality of users, and the object sharing behavior range diagram generated by the object sharing behavior range diagram presenting means based on the organization configuration information. May be visualized and presented within a specified range.

  The present invention further includes a task information management unit that holds task information performed by an organization composed of a plurality of users, and the object sharing action range diagram generation unit further sets other users as users belonging to the same task as the target user. An object sharing action range diagram may be generated, and another user may be selected on the condition that it belongs to the same task in addition to a condition for accessing an object having the same identity.

In this case, there is further provided an organization information management unit that holds organization configuration information composed of a plurality of users, and the object sharing action range diagram generation unit groups other users based on the organization configuration information. An action range diagram may be generated, and other users may be presented in groups corresponding to organization configuration information.
In this case, further, the object sharing action range diagram generating means may generate an object sharing action range diagram including information of other users belonging to the already completed task that has accessed the object having the same identity as the target user. Of course, an object sharing relationship with a past task may also be presented.

  In the present invention, an object shared by a plurality of users and a relationship between these users are presented as an object sharing action range diagram using an access log of a plurality of users for an object group in which a plurality of objects are associated in advance. For example, in the case of a document as an object, it is suggested to the analyst whether or not the document group structure has an appropriate structure according to the actual situation of business, and if not, what should be corrected. can do.

The present invention will be specifically described based on an example.
In the example described below, a document (data) is an object, and documents stored in the same document file are treated as having the same access. Note that the same processing may be performed depending on whether the same document is accessed for each document as the structure associated with each document.
In the following description, a document file is described as a document unless otherwise required.

  First, the document sharing behavior analysis support device of this example is used by connecting to a document sharing system 11 that manages a large number of documents that can be accessed by a plurality of users using an information processing device such as a PC, and the like. The document sharing system 11 includes a document repository storage unit 12 that holds association structure information (for example, a tree structure) of a document group in which a large number of documents to be provided to a user are associated, user identification information that accesses a document, access document identification It has a user access log storage means 13 for holding an access log including information, access date and time information, and the like.

  The document sharing behavior analysis support apparatus includes a document sharing log data acquisition unit 1 and a document sharing log data acquisition unit 1 that acquire document group structure information and user access log information from the document repository storage unit 12 and the user access log storage unit 13. Document sharing action range diagram manipulation by an analyst based on the information acquired by the document sharing action statistic calculation means 2 and the document sharing log data acquisition means 1 that calculate statistics on the access user and the access document based on the acquired information. Document sharing action range diagram generating means 3 for generating a document sharing action range diagram using an instruction from means 7 as a trigger, Document sharing action range diagram managing means 4 for holding the result generated by document sharing action range diagram generating means 3, and organization Organization information management means 5 for managing organization information including identification information and a plurality of user identification information constituting the organization Document sharing action range diagram display means 6 having a filtering function performed by referring to information and presenting a visualization image of the document sharing action range diagram generated in a form visible to an analyst using a bitmap display or the like, a mouse A document sharing action range diagram operating means 7 is provided for receiving an operation from an analyst related to generation of a document sharing action range diagram using a pointing device.

FIG. 2 shows an example of a document sharing action range diagram generated by the document sharing action range diagram generating unit 3 performing the process shown in FIG. It is.
The illustrated document sharing action range diagram represents the structure of a document group on the document sharing system 11 by a hierarchical structure of document folders (icons), and also shows users who are involved in document sharing actions (that is, access to the same document folder). Is displayed.

The folder hierarchy structure display 20 displays a part of the associated hierarchy structure of all folders on the document sharing system 11 and is an analysis target designated by the analyst from the document sharing action range diagram operating means 7. The folder group a to which the document accessed by the “target user” belongs is used as a base point, and the hierarchical folder structure of the document folder is traced from the base point to the upper side to reach the lowermost document folder c. All document folders b are drawn as icons.
In the display 21 of the user involved in the document sharing behavior, for the document folder a to which the document accessed by the target user A belongs, the document belongs to another user B who has accessed the document belonging to the folder a. The folder a is associated with a link or the like and displayed as an icon.

The folder hierarchy structure display 20 visually expresses the “breadth” in the document sharing behavior of the target user A, and the deeper the hierarchical structure of the document group, the more the documents shared on the document sharing system 11 are accessed. If the document group structure on the document sharing system is similar to the organizational structure, this suggests that the document sharing behavior across the organization is more than that.
In addition, in the display 21 of the users involved in the document sharing behavior, the more related users B are displayed as the number of users involved in the document sharing behavior increases, and the target user A and other users who are sharing the document sharing behavior with each other are displayed. This suggests the spread of activities.
In other words, the analyst can grasp the habit as described above from these displays, and can obtain hints such as correcting the structure of the organization or document to an appropriate one.

FIG. 3 shows an example in which the document sharing action range diagram displayed on the screen of the document sharing action range diagram display unit 6 is displayed again by changing the target user according to the operation from the document sharing action range diagram operation unit 7. It is. That is, this is an example of a traverse operation between users using a document sharing action range diagram.
As shown in FIG. 3A, when the user icon E is selected with the mouse pointer 7 while the target user A and other users B to E sharing the document are displayed, the user E is set as the target user. Then, the document sharing action range diagram generating means 3 newly generates a document sharing action range diagram by the same processing, and the document sharing action range diagram in which the user E is switched to the target user as shown in FIG. It is displayed on the screen 6.

This makes it possible to change the viewpoint of analysis one after another with other users who are sharing documents together as the target user, so that the actual state of document sharing behavior can be further explored.
The display of the target document structure is also based on the document repository information 12 and the user access log 13 as shown in FIG. 3A where the commonly accessed documents are (9), (13), and (16). As shown in (b), users B and C that have been changed to (16) and (28) and have not accessed these documents (16) and (28) are not displayed, and the other users F to H who have accessed are not displayed. Is displayed.

FIG. 4 shows an example in which the document sharing action range diagram is added with the statistics calculated by the document sharing action statistics calculation means 2 to the document and the user. In the illustrated example, the statistics are added and displayed only to the document (16) and the user E. However, the statistics may be added to all users, all shared documents, and all documents. Alternatively, it may be displayed only on either the document or the user.
This statistic is calculated by the document sharing behavior statistic calculation means 2 based on the access user log 13 and the access document structure information 12 acquired by the document sharing log data acquisition means 1, and the document sharing action range diagram is obtained using the calculation result. The generation unit 3 generates a document sharing action range diagram, which is additionally displayed.

As statistics, the number of joint accesses for the document file, the number of documents included in the document file, the number of read accesses from the document file, the number of write accesses to the document file are calculated and displayed. The number of accessed document folders and the diameter (size) of the target document folder group are calculated and displayed. Various types of statistics are set according to the access user log 13 and the access document structure information 12. Can do.
By displaying various statistics on document sharing behavior in this way, it is possible for an analyst to explore the actual state of document sharing behavior more deeply.

FIG. 5 shows an example in which the hierarchical range of the user displayed as the document sharing action range diagram is limited. That is, it is a filtering operation of the display target user.
This operation is performed in the combo box 22 displayed in the upper right of FIG. 5 (that is, the screen 6), and the analyst selects the user to be displayed using the operation means 7 at the distance on the organization to which the user belongs. It is specified. That is, referring to the organization information including the user identification information from the organization information management unit 5, the document sharing action range diagram display unit 6 sets the display range of the document sharing action range diagram as a range corresponding to the instruction.

In the illustrated example, only users whose “distance on organization” is 3 or less are displayed, and user E disappears from the display in FIG. This operation has an effect of making it easy to see the figure when there are many users to be displayed.
In addition to “distance on organization”, for example, the user access log 13 is used to perform various filtering such as “access within the last month”, “user close to age”, “specific job title”, etc. You can also

FIG. 6 shows an example of the data structure (graph) of the document sharing action range diagram generated by the document sharing action range diagram generating means 3.
Similar to the normal valid graph, it can be expressed by the relationship between nodes and edges, but the data necessary for the document sharing action range diagram of “node type”, “edge type”, and “statistics structure” It has been added.
“Node type” indicates whether the displayed node is a document folder or a user. “Edge type” indicates whether the displayed edge is an edge between the user and the document folder or an edge between the document folders. The “statistics structure” stores various statistics on document sharing behavior.

FIG. 7 shows a data sharing (graph) generation processing procedure of the document sharing action range diagram performed by the document sharing action range diagram generating means 3.
First, the document sharing action range diagram generating means 3 empties the graph structure G as a generation field (step S1), and then the information of the set F of document folders accessed by the target user u through the document sharing log data acquiring means 1 is obtained. Obtain (step S2).

Then, regarding the acquired plurality of document folder sets, the relationship between the document folders f and f ′ is such that f and f ′ are not equal and all the folders f and f ′ in which f and f ′ are both included in the folder set F. About the common folder f * that can be reached with the smallest number of paths in the document structure from both f and f ′ through the document shared log data acquisition means 1, the folder and link between f and f *, and f ′ Folders and links between f * are added to the graph G (step S3).
Then, it is confirmed whether or not the graph G includes an isolated subgraph (step S4). If so, a virtual root folder r is added to the graph G, and all of the end folders on the graph G are added. A link to r is added (step S5).

For all the folders included in the folder set F, the information of the user u ′ who has accessed the documents included in these folders is acquired through the document sharing log data acquisition unit 1, and the user u ′ and the user u ′ and the folder are acquired. A link between them is added to the graph G (step S6).
Thereby, data of a document sharing action range diagram (graph) is generated, and the document sharing action range diagram is displayed on the document sharing action range diagram display means 6 as shown in FIG.

FIG. 8 shows another configuration example of the document sharing behavior analysis support apparatus according to the present invention.
Compared with the example shown in FIG. 1, the document sharing action analysis support apparatus of this example adds task information management means 8, and further, the document sharing action range diagram generation means 3 includes organizational information management means 5 and task information management. The information stored in the means 8 is changed to be used.

FIG. 9 shows an example of task information data held and managed by the task information management means 8.
This task information data holds “task ID”, “checkpoint name”, “checkpoint date / time”, and “member at checkpoint (user ID)” for each checkpoint for the business unit managed as a task. Yes.
There are various existing devices that manage such “tasks”, such as project management devices and workflow management devices, and the task information management means 8 can be easily realized by sharing data with these devices. .

In this example, since the document sharing action range diagram generation unit 3 can handle the business entity indicated by the task, it is possible to display the difference between the document group structure and the actual business situation as a more direct visual image. Become.
FIG. 10 shows an example of a visualized image of the document sharing action range diagram generated and displayed according to this example.
In the document sharing action range diagram of this example, as shown in FIG. 10A, only the users A to D belonging to the task designated by the analyst from the operation means 7 are displayed, and the users indicating those users are displayed. The icons are displayed by grouping (A, B) (C, D) into organizational units hierarchized using the information of the organization information management means 8.

In addition to the side of the document sharing action range diagram, as shown in FIG. 10B, the checkpoints (CP1 to CP4) of the task and the target folder group diameter at each time point (from one end folder to another end folder). The graph shows the relationship of the maximum value among the shortest path lengths that can reach the folder.
In this graphed display, when the analyst selects a checkpoint from the operation means 7, the document group structure at the checkpoint is drawn with a thick line in the diagram of FIG.
Also, for example, in FIG. 10B, the diameter of the target folder group suddenly decreases at the time of the check point (CP3), and when the task reaches a certain check point, the document sharing action is performed. It can be seen that the document group accessed by a certain user is arranged in a very close range on the document structure of the document sharing system 11 and related documents are collected.
This suggests that the document group structure has an appropriate structure in accordance with the actual state of business.

FIG. 11 shows a data sharing graph generation process procedure of the document sharing action range diagram performed by the document sharing action range diagram generating means 3 in this example.
First, the document sharing action range diagram generating means 3 empties the graph structure G as a generation field (step S11), and then
Through the document shared log data acquisition means 1 and the task information management means 8, the folder set F accessed by the target user u until the time of the task T and the checkpoint CP selected by the analyst is acquired (step S12).

Then, regarding the acquired plurality of document folder sets, the relationship between the document folders f and f ′ is such that f and f ′ are not equal and all the folders f and f ′ in which f and f ′ are both included in the folder set F. About the common folder f * that can be reached with the smallest number of paths in the document structure from both f and f ′ through the document shared log data acquisition means 1, the folder and link between f and f *, and f ′ Folders and links between f * are added to the graph G (step S13).
Then, it is confirmed whether or not the graph G includes an isolated subgraph (step S14). If so, a virtual root folder r is added to the graph G, and all of the end folders on the graph G are added. A link to r is added (step S15).

And for all folders included in the folder set F,
Through the document shared log data acquisition unit 1 and the task information management unit 8, the user u ′ who has accessed the document included in the folder f up to the time of the selected task T and checkpoint CP is acquired, and the user u ′ and A link between the user u ′ and the folder is added to the graph G (step S16).
Thereby, data of a document sharing action range diagram (graph) is generated, and the document sharing action range diagram is displayed on the document sharing action range diagram display means 6 as shown in FIG.

In this example, not only the task that is currently in progress is displayed, but also the user E belonging to the task T2 that has already been completed is displayed as shown in FIG. 12, and the task 24 to which the user E belongs is displayed. It is also possible to display.
For example, in FIG. 12, since the user E is accessing the folder (4) and the task T2 to which the user E belongs is already in an end state, the folder (4) stores the result of the task that has already ended. Because the results are arranged within a very close range on the document group structure used by the task that is currently in progress, information transfer from another task is being performed properly. It is suggested.
By displaying such an appropriate document group structure, the analyst can examine which partial structure of the displayed document group structure should be corrected to obtain an appropriate structure. .
