Description

  The present invention relates to a classification support apparatus that supports design of a document classification system such as a directory.

  In recent years, many documents are managed electronically. For example, in companies, it is widely performed to manage documents using document management software. Such document management software generally allows a user to classify documents so that a desired document can be easily searched from a large number of documents. Specifically, in order to realize such document classification management, a file system having a hierarchical directory structure is often used.

  Here, a classification label (directory name) representing the contents of the classification, such as “general affairs document”, is set in the directory representing each classification. Some classifications may be associated with not only documents but also lower classifications (directories). For example, classifications such as “time attendance” and “personnel relations” may be further associated with the classification of “general affairs documents” as lower classifications.

Note that Non-Patent Document 1 discloses an example of a system that generates a list of what directory structure a website has.
“Full-automatic web diagnostic system WEB-Checks”, [online], [searched July 13, 2004], Internet <URL: http://www.syntax.co.jp/webchecks/>

  However, the design of the classification system and the classification of documents in the conventional document management software and the like are generally left to an administrator or the like. In this case, no index is presented as to whether or not the classification by the administrator is easy for the user to use. Further, although there is a system that generates a list of directory structures as disclosed in Non-Patent Document 1, information on whether or not the structure is easy to use for a user cannot be obtained. For this reason, the classification determined by the administrator is not necessarily usable for the user.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a classification support apparatus that presents an evaluation related to classification and can support design of a classification system and classification of documents.

  The present invention for solving the problems of the conventional example described above is characterized in that in the classification support program, a computer connected to a holding means for holding a document in association with one of a plurality of classifications is connected to the classification. A procedure for recording a user's access history to a document associated with any of the above, an evaluation calculation procedure for calculating an evaluation value for each classification based on the access history, and information on the generated evaluation value And a procedure to present is executed.

  Here, in the evaluation calculation procedure, when a history of referring to a list of documents associated with the target category is recorded, and a history of access to another category different from the target category is recorded. The evaluation value of the attention classification may be reduced. Further, in this evaluation calculation procedure, when the history of referring to the list of documents associated with the attention classification is recorded, and the history of access to the document associated with the attention classification is recorded. The evaluation value of the attention classification may be increased. Further, in the evaluation calculation procedure, when a history of user access to a document is recorded, if a history of access to a classification associated with the document is not recorded before the recording, At least the evaluation value of the classification may be reduced.

  In addition, the classification support program according to one aspect of the present invention provides any one of the above classifications to a computer that is connected to a holding unit that classifies and holds a document in association with any of a plurality of classifications. A procedure for recording a user's access history to a document associated with the document, an evaluation calculation procedure for calculating an evaluation value related to the classification of each document based on the access history, and information on the generated evaluation value And a procedure to present is executed.

  Furthermore, the present invention for solving the problems of the above conventional example uses a computer connected to a holding means for holding a document in association with one of a plurality of classifications. A step of recording a user's access history to a document associated with the document, an evaluation operation step of calculating an evaluation value of each classification based on the access history, and information relating to the generated evaluation value The process is performed.

  Furthermore, a classification support apparatus according to an aspect of the present invention is a classification support apparatus that is connected so as to be accessible to a holding unit that holds a document in association with one of a plurality of classifications. Means for recording a user's access history to a document associated with the device, means for calculating an evaluation value of each classification based on the access history, and means for presenting information relating to the generated evaluation value It is characterized by including.

  Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the classification support apparatus according to the embodiment of the present invention includes a control unit 11, a storage unit 12, a storage unit 13, an operation unit 14, a display unit 15, and a communication unit 16. And is connected to a client device C on the user side via a network.

  Here, the control unit 11 can be realized by using a CPU or the like, and operates according to a program stored in the storage unit 12. Specific contents of the processing of the control unit 11 will be described in detail later. The storage unit 12 can be realized by a memory element such as a random access memory (RAM) or a read only memory (ROM), a hard disk, or the like. The storage unit 12 holds a program executed by the control unit 11. The storage unit 12 also operates as a work memory that holds various data used in the process of the control unit 11.

  The storage unit 13 holds document entity data. This storage unit 13 corresponds to the holding means of the present invention. In the present embodiment, the storage unit 13 classifies and stores documents using a hierarchical directory structure.

  The operation unit 14 can be realized by a mouse, a keyboard, or the like. The operation unit 14 accepts a user operation and outputs the content of the operation to the control unit 11. The display unit 15 is a display or the like, and displays and outputs information according to instructions input from the control unit 11. The communication unit 16 is connected to a network, and transmits and outputs data via the network in accordance with an instruction input from the control unit 11. Further, the communication unit 16 receives data (such as a document request from the client device C) received via the network and outputs the data to the control unit 11.

  Here, the specific content of the process performed by the control part 11 is demonstrated. The control unit 11 receives a request to access a document stored in the storage unit 13 and executes a process of presenting the document in response to the request. Specifically, the control part 11 here demonstrates as what operate | moves as a web server.

  When receiving an access from the client device C, the control unit 11 authenticates the user of the client device C with a user name, a password, or the like. When the authentication is successful, such as when a predetermined user name and a password corresponding to the user name are received from the user side, the control unit 11 issues a unique session identifier and uses it as a cookie (Cookie) or the like. Send to.

  The client device C holds this session identifier, and transmits this session identifier together with an access request to a document or directory. When the control unit 11 receives an instruction to log out (end of session) from the client device C, the control unit 11 instructs the client device C to delete the session identifier, and the client device C deletes the session identifier cookie.

  Upon receiving an access request including the designation of a directory in the storage unit 13, the control unit 11 transmits the lower directory included in the designated directory and document list data to the requesting client apparatus C. To do. In addition, when receiving an access request including a document specification, the control unit 11 transmits the specified document to the client device C. Here, the designation of a directory or a document is performed by, for example, a URL (Uniform Resource Locator).

  The control unit 11 also executes processing (recording processing) for recording a history of access to the user's document. In this recording process, information specifying the directory or document specified in the access request received via the network and the user (or client device C) making the request (client specifying information) The session identifier is associated with the date and time information (acquired from a clock (not shown)) when the access request is accepted, and stored in the storage unit 13 as a history database. The contents of this history database are, for example, as shown in FIG.

  The control unit 11 calculates the evaluation value of the directory corresponding to the classification and the evaluation value related to the classification of each document with reference to the contents of the history database thus recorded. In the present embodiment, as shown in FIG. 3A, for each directory, a directory evaluation table in which information for specifying a directory and information on its evaluation value are associated is stored in the storage unit 12. Further, as shown in FIG. 3B, for each document, a document classification evaluation table in which information for specifying a document and evaluation value information related to the classification of the document are associated is stored in the storage unit 12.

  Next, directory evaluation value calculation processing will be described. The control unit 11 separates the access records recorded in the history database for each session (a series of user access records). More specifically, the access record recorded in the history database is divided into session records composed of records including the same session identifier. Then, the following processing is performed for each session record.

  The control unit 11 rearranges the access records included in the session record in order of date and time while referring to the date and time information. Then, a directory access record (a record referring to a list of documents and subdirectories in the directory) is searched. The control unit 11 records the access to the directory found by the search (the directory accessed by this record is referred to as the noticed directory here), and the access to another directory different from the noticed directory is recorded. The evaluation value stored in the storage unit 12 in association with the target directory is reduced. Specifically, the evaluation value associated with the target directory is reduced by a predetermined value.

  Furthermore, for example, referring to the access order to the directory, after accessing in the lower direction of the hierarchy, the access to the document is not performed, and then the upper direction is accessed. In addition, the evaluation value associated with the lowest directory in the series of accessed directories is reduced. Specifically, the evaluation value associated with the lowest directory is reduced by a predetermined value.

  Specifically, in the present embodiment, for each directory in the storage unit 13, a numerical value (hierarchy depth information) representing the depth of the hierarchy is stored in association (FIG. 4). For example, it is assumed that the directory level of “General Affairs” associated with the root directory is “1”, the directory of “HR Documents” associated with this “General Affairs” is “2”, and so on. Then, the control unit 11 refers to the layer depth information for each access record to the directory, increases the value of the layer depth information, and then continues (without accessing the document) the value of the layer depth information. The access record corresponding to the extreme value of the hierarchical depth information is found. Then, the evaluation value of the directory related to the found access record (the lowest directory among a series of accessed directories) is reduced.

  As a result, as shown in FIG. 5, when the user obtains a desired document from the upper directory and descends down the directory hierarchy (S 1, S 2), the desired document is eventually obtained. In the case where the document is not found and returns to the top (S3), the evaluation regarding the classification in which the desired document cannot be found is reduced.

  On the other hand, after the access records included in the session record are rearranged in order of date and time with reference to the date and time information, the access record to the document is searched. The control unit 11 uses the directory accessed immediately before the record of access to the document found by the search (the directory to which the document found by the search is associated) as the noticed directory, and associates the noticed directory with the storage part. The evaluation value stored in 12 is increased. Specifically, the evaluation value associated with the directory of interest is increased by a predetermined value. In other words, after access to a directory of interest, if a history of access to a document associated with the directory of interest is recorded, it is estimated that this means that a desired document has been found in the directory of interest. Therefore, the evaluation value of the target directory is increased.

  The control unit 11 further displays the evaluation value thus calculated on the display unit 15. With reference to the display of the evaluation value, the administrator can consider a countermeasure for the directory having a low evaluation value. Here, countermeasures include changing the directory name, creating a new directory, or moving the directory (eg, associating it with other directories).

  Further, the control unit 11 calculates an evaluation value related to the classification of the document. In this embodiment, a plurality of documents accessed during one session are recorded as co-occurrence access documents. Specifically, as shown in FIG. 6, the control unit 11 stores in the storage unit 12 a co-occurrence access table that represents the number of accesses (number of co-occurrence accesses) related to a document pair accessed during the same session. is doing. In FIG. 6, the value in the lower left triangle is not the same as the value set in the upper right triangle (the number of co-occurrence accesses between documents a and b is the same between documents b and a). This is because it is the same as the number of times of access.

  The control unit 11 performs the following processing to generate a co-occurrence access table. First, the control unit 11 separates the access records recorded in the history database for each session (a series of user access records). In other words, the access records recorded in the history database are divided into session records composed of records including the same session identifier, and the number of sessions is counted.

  Then, the control unit 11 refers to the access record to the document included in each session record, and checks whether or not a plurality of documents are accessed during one session. Here, if a plurality of documents are accessed, they are selected as co-occurrence access documents, and a combination (document pair) of documents obtained by arbitrarily selecting two documents from the co-occurrence access documents is selected and selected. The co-occurrence access count for each document pair is incremented, and the co-occurrence access table is updated.

  For example, when documents A, B, and C are accessed in one session, these become co-occurrence access documents, and a combination of documents A and B, a combination of documents B and C, and documents A and C The number of co-occurrence accesses related to the combination is incremented.

  When the update of the co-occurrence access table is completed for all the sessions, the control unit 11 divides the number of co-occurrence accesses on the co-occurrence access table by the number of sessions, and for each pair of documents, Calculate the ratio of co-occurrence access documents per session.

  The control unit 11 identifies document pairs in which the calculated ratio exceeds a predetermined threshold value. Then, it is checked whether or not the two documents related to the document pair are associated with different directories. Here, when the two documents are associated with different directories, information for specifying the two documents and information for specifying the directory including each document are notified for the two documents. The information is stored in the storage unit 12 as target information. The control unit 11 then displays and outputs the notification target information stored in the storage unit 12 on the display unit 15.

  The administrator can recognize the document pair to be associated with the same directory by referring to the information to be notified.

  Furthermore, the control unit 11 refers to the notification target information, and generates a list of directory groups (directory groups each including each document of the document pair) related to the notification target information. Then, the value of the appearance frequency of each directory set is calculated.

  For example, when there are documents a1, a2, and a3 included in the directory A and documents b1 and b2 included in the directory B, the notification target information includes a1 and b1, a1 and b2, a2 and b1, a2 and b2. , A3 and b1 document pairs are included. In this case, five sets of directories A and B appear as a set of directories related to the notification target information.

  For each set of directories included in the generated list, the control unit 11 determines the number of combinations obtained by extracting documents from each of the two directories in the set (in the case of a set of directories A and B, directory A Product of the number of documents included in the directory B and the number of documents included in the directory B). Then, for each set of directories, a value (pair content rate) obtained by dividing the appearance frequency in the list by the calculated number of combinations is calculated.

  If there is a directory set whose pair content rate exceeds a predetermined threshold among the set of directories, information specifying the set of the directory (the directories of the two directories included in the set) Name) is displayed on the display unit 15.

  By referring to this display, the administrator can know that there is a high probability that many users will access the documents in the two directories in one session. For example, one administrator integrating the two directories Measures such as creating a directory can be considered.

  As described above, according to the present embodiment, it is possible to provide information related to the evaluation of the directory configuration and the document classification, and support the design of the classification system and the document classification.

  Further, the control unit 11 not only has a mode of accessing a document by tracing a directory, but also, for example, receives a search word input from a user and presents a list of documents related to the search word as a search result (so-called so-called search result). Full-text search processing) may be executed. At this time, the control unit 11 adds a record indicating that the search has been performed and a search result to the access history.

  When the search is performed in this way, the control unit 11 calculates a correlation value between the directory containing the search result document based on the given search word and the search word, and the correlation value is determined in advance. When the value is lower than the threshold, the display unit 15 may display that the name of the directory is not appropriate. This correlation value is obtained by, for example, referring to a correlation value table in which the correlation values of word pairs included in a predetermined word group are determined in advance, and calculating the sum of correlation values between words included in the search word and words included in the directory name. It can be calculated and calculated.

  Further, when the user accesses a document found by the search, the access history records the access to the document after the search result is recorded. If the history of access to the classification (directory) with which the document is associated is not recorded before recording the access to the document, the control unit 11 sets at least the evaluation value of the classification. Reduce. For example, when a directory that is a category is hierarchically configured, the evaluation value of each category on the path from the root to the category (the category to which the accessed document belongs) may be reduced.

  Specifically, when the access to the document is recorded after the search result is recorded, the control unit 11 is a list of documents in which the access target immediately after the presentation of the search result is the search result. To see if it is included in. If the document to be accessed is included in the list, the evaluation value of each directory on the path from the root directory to the directory including the document to be accessed is reduced. Specifically, a certain value is subtracted from the evaluation value of each directory. For example, in order to access a document found by a search, it is necessary to trace the directory A → B → C from the root (the document is classified into the directory C). The evaluation values of the directories A, B, and C on the paths up to are reduced.
