[3. Details of processing]
Next, details of processing executed in the information processing system 1 will be described with reference to FIGS.

[3-1. Processing when registering operation history data]
First, an example of processing executed when the information processing terminal 20 registers operation history data in the information management apparatus 10 in the information processing system 1 will be described with reference to the sequence diagram shown in FIG.

  As illustrated in FIG. 6, when the information processing terminal 20 receives an operation input from the user (S101), the information processing terminal 20 executes document data editing processing based on the received operation input (S102). Here, the editing process may include processes such as opening, closing, and duplicating document data.

  The information processing terminal 20 records the operation history data based on the executed document data editing process (S103). For example, the information processing terminal 20 may record the user ID, operation date / time, operation command, and operation target file name (path name) as operation history data.

  When the operation history data transmission timing has not arrived (S104: N), the information processing terminal 20 returns to S101 and continues the subsequent processing, and when the operation history data transmission timing has arrived. (S104: Y), operation history data to be transmitted and document data are selected (S105). For example, the information processing terminal 20 may determine that the transmission timing has arrived every time a predetermined time interval elapses, or a predetermined event such as an operation input has occurred. Each time, it may be determined that the transmission timing has arrived. Then, the information processing terminal 20 may select operation history data that has not been transmitted to the information management apparatus 10 and document data as transmission targets. Here, even if the document data has already been transmitted, the information processing terminal 20 may select the updated document data as a transmission target when the document data is updated after the transmission.

  The information processing terminal 20 transmits the operation history data selected in S105 and the document data to the information management apparatus 10 (S106). If the information processing terminal 20 does not end the document processing (S107: N), the process returns to S101 and repeats the subsequent processing. If the document processing ends (S107: Y), the processing is performed. finish.

  When the information management apparatus 10 receives the operation history data and the document data transmitted from the information processing terminal 20 in S106, the information management apparatus 10 assigns a document ID to the received document data, and then a document data management table (see FIG. 4). (S108), and the operation history data received from the information processing terminal 20 is stored in the history data management table (see FIG. 3) (S109). When the document data corresponding to the file path of the document data received from the information processing terminal 20 has already been stored in the document data management table, the information management apparatus 10 stores information on the stored document data ( If the document data corresponding to the file path of the document data received from the information processing terminal 20 is not stored in the document data management table, a new document ID is assigned to the document data. Information (records) may be added to the management table.

  Next, when the timing for determining the relationship between documents has not arrived (S110: N), the information management apparatus 10 returns to before S108, and the operation history data from the information processing terminal 20 and the document When it is time to determine the relationship between documents after waiting for data transmission (S110: Y), a process for determining the relationship between documents (inter-document relationship determination process) is executed (S111). ). After completing the process of S111, the information management apparatus 10 returns to before S108 and waits for transmission of operation history data and document data from the information processing terminal 20. Next, details of the inter-document relationship determination process executed by the information management apparatus 10 will be described with reference to the flowcharts of FIGS.

[3-2. Inter-document relationship determination process]
7 and 8 are flowcharts showing the inter-document relationship determination process. As shown in FIG. 7, the information management apparatus 10 selects document data to be processed (here, document data D _{1 to DN} , where N is an integer equal to or greater than 1) (S201). For example, the information management apparatus 10 registers (or updates information) in the document data management table within a specified period (for example, within a predetermined period from the current time) among the document data associated with the specified user ID. It is also possible to select at least one of the document data and the document data that is the operation target in the history data registered in the history data management table as the processing target. The inter-document relationship determination process may be executed for each user ID.

Next, the information management apparatus 10 initializes the variable i to 1 (S202), extracts the operation history data about the document data _{D i} from the history data management table (S203). For example, the information management apparatus 10 may as to extract the operation history data (records) including the document ID of the document data D _i from the history data management table.

Information management apparatus 10 based on the operation history data extracted for the document data D _i, if the document data D _i is determined to have been copied from another document data (S204: Y), the document data D _i Is recorded in the relationship management table (see FIG. 5) (S205). For example, the information management apparatus 10, in the operation history data extracted for the document data D _i, if the document data D _i is included an operation command indicating that created by the replication of other document data adds a new record to the relationship management table, and stores the newly generated ID to relationships ID of the added record, the document ID of the document data D _i in the main document ID, a copy source to従文document ID It is possible to store the document ID of the document data of “1” and “1: Duplicate” as the content of the relationship in association with the operation date and time in the operation history data on the date of occurrence of the relationship.

Information management apparatus 10 based on the operation history data extracted for the document data D _i, if the document data D _i is not determined to have been copied from another document data: and (S204 N), after the step S205 , based on the operation history data extracted for the document data D _i, it determines whether there are other document data co-occurrence relationship with the document data D _i (S206). For example, in the operation history data extracted for the document data D _i , the information management apparatus 10 shares the shared document data when there is other opened document data from when the document data D _i is opened until it is closed. It is determined that there is other document data of the origin relationship, and otherwise, it is determined that there is no other document data of the co-occurrence relationship.

If the information management apparatus 10 determines in S206 that there is other document data having a co-occurrence relationship with the document data D _i (S206: Y), the document data D _i is co-occurrence with other document data. The relationship is recorded in the relationship management table (see FIG. 5) (S207). For example, the information management apparatus 10, when determining that there are other document data co-occurrence relationship with the document data D _i adds a new record to the relationship management table, relationship ID of the added record to store the newly generated ID, the main document ID of the document data D _i in the document ID, and document ID of the other document data in co-occurrence relation to従文document ID, the contents of the relationship "2: co “Occurrence” may be stored in association with the operation date and time in the operation history data (for example, the date and time when other document data having a co-occurrence relationship is opened) on the occurrence of the relationship.

When there is no other document data having a co-occurrence relationship in the document data D _i (S206: N), the information management apparatus 10 generates a feature vector V _i for the document data D _i after S207 (S208). For example, the feature vector V _i may be calculated based on the word included in the document data D _i and its importance, or may be calculated by another method.

The information management apparatus 10 identifies which of the plurality of clusters into which the feature vectors V _i of the document data D _i belong to the respective feature vectors of the document data stored in the storage unit 12 belongs, and the identified cluster A document data group (document data d _{i1 to} d iMi in this _example ) _belonging to is selected (S209). Note that Mi is an integer of 1 or more. Here, for example, the information management apparatus 10 may calculate the distance between the representative feature vector of each cluster and the feature vector V _i and specify the cluster having the smallest distance as the cluster to which the document data D _i belongs. Here, the processing after S209 will be described with reference to FIG.

As shown in FIG. 8, the information management apparatus 10 initializes a variable j to 1 (S210), and determines whether or not the document data D _i and the document data d _ij are similar data (S211). . For example, the information management apparatus 10 may determine that the distance between the feature vector of the document data D _{i and} the feature vector of the document data d _ij is similar if the distance is equal to or smaller than the threshold, and dissimilar if the distance is larger than the threshold.

When the document data D _i is similar to the document data d _{ij in} S211 (S211: Y), the information management apparatus 10 proceeds to S212, and the document data D _i is dissimilar to the document data d _ij. (S211: N), the process proceeds to S217.

Information management apparatus 10, in S212, if the document data _{D i} and the document data _{d ij} is determined that the copy relationship (S212: Y), the document data _{D i,} and the document data _{d ij} The diversion relationship is recorded in the relationship management table (see FIG. 5) (S213), and if it is determined that the document data D _i and the document data _dij are not in a replication relationship (S212: N), the document data For D _i , the similarity relationship with the document data d _ij is recorded in the relationship management table (see FIG. 5) (S214). For example, the information management apparatus 10 determines whether or not the operation history data extracted for the document data D _i includes a copy operation history using the document data d _ij as a copy source. It may be determined whether _i and document data d _ij have a replication relationship.

After S213 or S214, the information management apparatus 10 determines whether the file paths of the document data D _i and the document data _dij are similar (S215). For example, the information management apparatus 10, a character string of the file path of the document data D _i, the file path of the document data d _ij and if the string matches more than a predetermined ratio, the document data D _i file path If the difference between the character string and the character string of the file path of the document data _dij is only a predetermined format (for example, only numbers), it is determined that they are similar, and if not, both May be determined to be dissimilar.

If it is determined in S215 that the file paths of the document data D _i and the document data d _ij are similar (S215: Y), the information management apparatus 10 compares the document data d _i with the document data d _i . The revision relationship with _ij is recorded in the relationship management table (see FIG. 5) (S216).

Information management apparatus 10, after S216, when the file path of the document data _{D i} and the document data _{d ij} is dissimilar (S215: Y), or the document data _{D i} is the document data _{d ij} and dissimilar If there is (S211: N), it is determined whether or not the document data D _i includes data referring to the document data d _ij (S217). For example, the information management apparatus 10, in the document data D _i, based on whether including the document data d _ij file path (file name) may as executing the determination processing of S217.

Information management apparatus 10, when the document data _{D i} is determined to include the data referring to document data _{d ij} in S217 (S217: Y), the document data _{D i,} to the document data _{d ij} The reference relationship is recorded in the relationship management table (see FIG. 5) (S218). Further, the information management apparatus 10 further determines whether containing data referring to document data D _i in the document data d _ij, based on the determination result, the document data d _ij, document data a reference relationship to D _i, may be recorded in the relationship management table.

The information management apparatus 10 proceeds to S219 after S218 or when the document data D _i does not include data referring to the document data _dij (S217: N). Here, the information management apparatus 10, the variable j is, when the document data _{D i} does not reach the number of documents Mi belonging cluster (S219: N), to the variable j (1 added to j) is incremented (S220) Returning to S211, the subsequent processing is repeated, and when the variable j reaches Mi (S219: Y), the process proceeds to S221.

  Here, when the variable i has not reached the target document data number N (S221: N), the information management apparatus 10 increments the variable i (adds 1 to i) (S222), and returns to S203 in FIG. Then, the subsequent processing is repeated, and when the variable i reaches the target document data number N (S221: Y), the process returns to exit the inter-document relationship determination processing.

  The above is an example of processing executed when registering operation history data in the information processing system 1. Next, an example of providing information to the user using the relationship between documents analyzed in FIGS. 6 to 8 will be described.

[3-3. Related document provision processing]
For example, it may be possible to provide a user with a document that directly has a specified relationship with the document of interest, but the document of interest is not directly related to the document of interest. It is quite possible that there are existing and useful documents. Therefore, in the present embodiment, the information management apparatus 10 determines that the document having the second relationship in common with the plurality of documents having the first relationship with the document of interest is the second document. Processes provided as related documents that are highly likely to have a relationship are executed. Hereinafter, the related document providing process by the information management apparatus 10 according to the present embodiment will be described with reference to first and second examples.

[3-3-1. First related document provision process]
First, details of the first related document providing process will be described with reference to FIGS. 9 and 10.

FIG. 9 is a diagram illustrating the relationship between the document of interest and the related document according to the first example. In FIG. 9, D is an attention document, and the attention document D may be specified based on, for example, designation from the information processing terminal 20. Then, D _A is a document having a relationship r with respect to the target document D, target document D with respect to the relationship r main document D _A indicates that it is in the slave relationship. Here, for example, in the replication relationship, the replication destination is primary and the replication source is secondary, in the diversion relationship, the diversion destination is primary and the diversion source is secondary, and in the reference relationship, the reference source is primary, The reference destination may be in a subordinate relationship.

D _B and D _C are documents that are in the relationship r to the document D _{A as} in the noted document D. That is, the document D _B and the document D _C is subordinate document D _A with respect to the relationship r, a document which themselves mainly, where the first document group a group of documents as elements document D _B and the document D _C is Called.

D _D and D _E are documents having a common relationship R with respect to two or more documents included in the first document group. That is, the document _{D D} and the document _{D E} are both documents _{D B} and the document _{D C} Relationship R major (or slave), a document to follow their own (or primary), the document _{D D} and the document D here A document group having _E as an element is referred to as a second document group.

  Here, since the second document group having the relationship R with respect to the first document group may have the relationship R with the document of interest D, in the first related document providing process, The document group is provided as a related document that may be in the relationship R with the document of interest D.

  Next, the details of the first related document providing process executed by the information management apparatus 10 will be described with reference to the flowchart shown in FIG.

  As illustrated in FIG. 10, the information management apparatus 10 selects the document of interest D based on, for example, data received from the information processing terminal 20 (S301). For example, the information management apparatus 10 may receive the document ID and select the target document D, or may select the target document D based on the result of searching for data that matches the search conditions.

The information management apparatus 10 identifies the first relationship r ₁ to r _N for identifying a document having a common relationship with the document of interest D and a document in which the document of interest D may potentially have a relationship. The second relations R _{1 to} R _M for setting are set. For example, when “replication” and “reference” are set for the first relationship, N = 2, r ₁ = replication, r ₂ = reference, and “co-occurrence” is set for the second relationship , M = 1 and R ₁ = co-occurrence. Here, the contents of the first relationship and the second relationship may be specified by the information processing terminal 20 or may be determined in advance.

Information management apparatus 10, (S303) after initializing a variable i to 1, with the relationship management table, first a document having a document of interest D in the first relation r _i, the first relationship r _i A plurality of other documents are searched as the first document group (S304). For example, for the first relationship r _i , the information management apparatus 10 relates to one subordinate document (or main document) whose main document (or subordinate) is the document of interest D, with respect to the one subordinate document (or main document). Thus, a plurality of documents having a main (or subordinate) relationship as in the noted document D may be searched as the first document group.

When the first document group is searched in S304 (S305: Y), the information management apparatus 10 initializes the variable j to 1 (S306), and then stores two or more documents included in the first document group. One or more documents having the second relationship R _j are searched as a second document group (S307). For example, for the second relationship Rj, the information management apparatus 10 commonly uses one or more documents that mainly include documents included in the first document group, or a document included in the first document group. One or more documents may be searched as the second document group.

  When the second document group is searched in S307 (S308: Y), the information management apparatus 10 adds the document of the second document group to the elements of the document set Dij (S309).

If the first document group is not searched in S304 after S309 (S305: N), or if the second document group is not searched in S307 (S308: N), the information management apparatus 10 It is determined whether j has reached M (S310). If the variable j has not reached M (S310: N), the information management apparatus 10 increments j (adds 1) (S311), returns to S307, and repeats the subsequent processing. If the variable j has reached M (S310: Y), the information management apparatus 10 determines whether the variable i has reached N (S312). If the variable i has not reached N (S312: N), the information management apparatus 10 increments i (adds 1) (S313), returns to S304, and repeats the subsequent processing. Further, when the variable i has reached N (S312: Y), the information management device 10 determines the information processing terminal based on the information of the document set D _ij (i = 1 to N, j = 1 to M). Document information is provided to 20 (S314).

For example, the information management apparatus 10 includes the documents included in the document sets D _{1k to} D _Nk as a list of documents that may have the relationship R _k (k is any one of 1 to M) with respect to the target document D. Information may be provided. At this time, when the document list is divided for each first relationship, the information management apparatus 10 transmits information on the documents included in the document set D _ik to the information processing terminal 20 for the first relationship r _i . You may make it provide.

[3-3-2. First related document provision process]
Next, details of the second related document providing process will be described with reference to FIGS. 11 and 12.

FIG. 11 is a diagram illustrating the relationship between the document of interest and the related document according to the second example. In FIG. 9, D is an attention document, and the attention document D may be specified based on, for example, designation from the information processing terminal 20. _{Then, D A, D B, D} C , respectively, a document with the relationship r (e.g. similar relationship) with respect to the target document D, _{also, D A, D B, D} C also mutually have a relationship r ing. Here, the document group including the document of interest D and a plurality of documents having the relationship r to each other as elements is referred to as a first document group.

_DD is a document having a common relationship R with respect to two or more documents included in the first document group. For example, the document _{D D} is a document having a document _{D A, D B, D C} a relation R. A document group including each of two or more documents included in the first document group and one or more documents having the relationship R is referred to as a second document group.

  Here, since the second document group having the relationship R with respect to the first document group may have the relationship R with the document of interest D, in the second related document providing process, The document group is provided as a related document that may be in the relationship R with the document of interest D.

  Next, details of the second related document providing process executed by the information management apparatus 10 will be described with reference to the flowchart shown in FIG.

  As illustrated in FIG. 12, the information management apparatus 10 selects the document of interest D based on, for example, data received from the information processing terminal 20 (S401). For example, the information management apparatus 10 may receive the document ID and select the target document D, or may select the target document D based on the result of searching for data that matches the search conditions.

The information management apparatus 10 identifies the first relationship r ₁ to r _N for identifying a document having a common relationship with the document of interest D and a document in which the document of interest D may potentially have a relationship. The second relations R _{1 to} R _M for setting are set. For example, when “similar” is set for the first relationship, N = 1 and r ₁ = similar, and when “co-occurrence” is set for the second relationship, M = 1 and R ₁ = Co-occurrence. Here, the contents of the first relationship and the second relationship may be specified by the information processing terminal 20 or may be determined in advance.

After initializing the variable i to 1 (S403), the information management apparatus 10 sets a document group including a plurality of documents having the first relationship r _i and the document of interest D as the first document from the relationship management table. Search as a group (S404). Here, the information management apparatus 10 may have a plurality of documents searched as the first document group having a first relationship r _i to each other.

When the first document group is searched in S404 (S405: Y), the information management apparatus 10 initializes the variable j to 1 (S406), and then stores two or more documents included in the first document group. One or more documents having the second relationship R _j are searched as the second document group (S407). For example, for the second relationship Rj, the information management apparatus 10 commonly uses one or more documents that mainly include documents included in the first document group, or a document included in the first document group. A document group having one or more documents as elements may be searched as the second document group.

  When the second document group is searched in S407 (S408: Y), the information management apparatus 10 adds the document of the second document group to the elements of the document set Dij (S409).

If the first document group is not searched in S404 after S409 (S405: N), or if the second document group is not searched in S407 (S408: N), the information management apparatus 10 performs the variable It is determined whether j has reached M (S410). If the variable j has not reached M (S410: N), the information management apparatus 10 increments j (adds 1) (S411), returns to S407, and repeats the subsequent processing. Further, when the variable j has reached M (S410: Y), the information management apparatus 10 determines whether the variable i has reached N (S412). If the variable i has not reached N (S412: N), the information management apparatus 10 increments i (adds 1) (S413), returns to S304, and repeats the subsequent processing. Further, when the variable i has reached N (S412: Y), the information management device 10 determines the information processing terminal based on the information of the document set D _ij (i = 1 to N, j = 1 to M). The document information is provided to 20 (S414).

For example, the information management apparatus 10 includes the documents included in the document sets D _{1k to} D _Nk as a list of documents that may have the relationship R _k (k is any one of 1 to M) with respect to the target document D. Information may be provided. At this time, when the document list is divided for each first relationship, the information management apparatus 10 transmits information on the documents included in the document set D _ik to the information processing terminal 20 for the first relationship r _i . You may make it provide.

  The first related document providing process and the second related document providing process may be executed independently, or when there is no relevant related document in the first related document providing process, the second related document providing process is performed. The first related document providing process may be executed when there is no relevant related document in the second related document providing process.

  According to the information processing system 1 described above, a plurality of documents having a first relationship common to a document of interest are compared with other documents having a second relationship in common with the document of interest. It can be provided as a related document that may have two relationships.

  The present invention is not limited to the above embodiment. For example, in the above embodiment, the document data has been described as an example, but the present invention may be applied to data other than the document data.
