Hereinafter, an example of a preferred embodiment for realizing the present invention will be described with reference to the drawings.
FIG. 1 shows a conceptual module configuration diagram of a configuration example of the present embodiment.
The module generally refers to components such as software (computer program) and hardware that can be logically separated. Therefore, the module in the present embodiment indicates not only a module in a computer program but also a module in a hardware configuration. Therefore, the present embodiment is a computer program for causing these modules to function (a program for causing a computer to execute each procedure, a program for causing a computer to function as each means, and a function for each computer. This also serves as an explanation of the program and system and method for realizing the above. However, for the sake of explanation, the words “store”, “store”, and equivalents thereof are used. However, when the embodiment is a computer program, these words are stored in a storage device or stored in memory. It is the control to be stored in the device. Modules may correspond to functions one-to-one, but in mounting, one module may be configured by one program, or a plurality of modules may be configured by one program, and conversely, one module May be composed of a plurality of programs. The plurality of modules may be executed by one computer, or one module may be executed by a plurality of computers in a distributed or parallel environment. Note that one module may include other modules. Hereinafter, “connection” is used not only for physical connection but also for logical connection (data exchange, instruction, reference relationship between data, etc.). “Predetermined” means that the process is determined before the target process, and not only before the process according to this embodiment starts but also after the process according to this embodiment starts. In addition, if it is before the target processing, it is used in accordance with the situation / state at that time or with the intention to be decided according to the situation / state up to that point. When there are a plurality of “predetermined values”, they may be different values, or two or more values (of course, including all values) may be the same. In addition, the description having the meaning of “do B when it is A” is used in the meaning of “determine whether or not it is A and do B when it is judged as A”. However, the case where it is not necessary to determine whether or not A is excluded.
In addition, the system or device is configured by connecting a plurality of computers, hardware, devices, and the like by communication means such as a network (including one-to-one correspondence communication connection), etc., and one computer, hardware, device. The case where it implement | achieves by etc. is included. “Apparatus” and “system” are used as synonymous terms. Of course, the “system” does not include a social “mechanism” (social system) that is an artificial arrangement.
In addition, when performing a plurality of processes in each module or in each module, the target information is read from the storage device for each process, and the processing result is written to the storage device after performing the processing. is there. Therefore, description of reading from the storage device before processing and writing to the storage device after processing may be omitted. Here, the storage device may include a hard disk, a RAM (Random Access Memory), an external storage medium, a storage device via a communication line, a register in a CPU (Central Processing Unit), and the like.

The information processing apparatus according to the present embodiment extracts related documents of documents managed in the document life cycle, estimates the necessity of reference after phase transition, and performs access control. FIG. As shown in the example, the document operation module 110, the document storage DB 115, the access right change module 120, the document life cycle management module 125, the document life cycle DB 130, the related document detection module 135, the operation monitoring recording module 140, the operation history DB 145, It has a related information operation history DB 150 and a related document access right automatic control module 160.
An overview of the processing of the present embodiment will be described. Based on the access status extracted using the operation history information, the extraction of the unmanaged document (related document) related to the phase document and the usage status of the related document after the phase shift are predicted, and the access right of the related document is changed.

In the case of documents that have high confidentiality such as customer information and must be strictly managed, it is necessary to perform appropriate processing such as promptly disposing of the document when it is finished. Originally, it should be strictly managed by determining appropriate rules for the relevant document, but the document life cycle (hereinafter also simply referred to as the life cycle) is applied in part where the process is defined. Documents (also referred to as phase documents, corresponding to the first document and the third document), and documents used to create some documents (corresponding to the second document and the fourth document) For example, for a temporarily created document), the life cycle is not applied in most cases. In that case, conventionally, it is often left to management by an organization or an individual, and there are cases where it is not deleted appropriately. And it may cause serious accidents such as information leakage.
That is, a document to which the life cycle is not applied remains without being discarded. Or it is difficult to determine when a document that has not been applied to the life cycle must be discarded. In other words, depending on the state of the managed document, some documents may be used thereafter. For example, it is difficult to determine whether the system administrator tries to discard the managed document together with discarding the managed document.

  Note that the document life cycle (document life cycle) is divided into phases such as “occurrence (creation, acquisition)”, “communication”, “utilization”, “storage”, “preservation”, “disposal”, and the like. The document in which phase management is performed means that it is possible to manage which stage in the document life cycle the document is, for example, a document management system having a document life cycle function And the like, the document properties, etc. have a document life cycle stage. The present embodiment is used for such a document management system.

A phase is a step for a document defined in the document life cycle. The content to be performed on the document is defined. For example, there are document creation, approval, storage, and deletion.
A phase document is a document that must be managed in the document life cycle. A document type is set for the document. For example, a plurality of phases are defined sequentially for each document type. The defined phase group is fixed with respect to the document type. That is, a one-to-one relationship is established. These phase documents are stored in the document management system. For example, there are contracts, specifications, deliverable documents, and the like.
The document type is a document type defined for the phase document. It is defined by the nature and role of the document.

A related document is a document used in handling a phase document. It is not managed in the document life cycle and the phase is not applied. That is, the document type is not set. These related documents are stored in the document management system.
The document management system is an information processing apparatus having a function as a storage in which documents used in business are stored. Both documents that should be strictly managed and documents that are not strictly stored are stored. In order to prevent the stored document from being taken out without permission, the stored document cannot be taken out.
The access pattern model is a model (pattern) that represents the frequency status of operations on phase documents. For each document type, there are an access pattern model for a reference operation for a phase document, an access pattern model for an edit operation for a phase document, and the like.

The document life cycle DB 130 is a DB in which a plurality of phases are defined for each document life cycle. Consists of existing technology. One document type is set for one document life cycle. The document type is information indicating the type (type) of the document, such as a contract or a plan. Documents of the same type have the same document life cycle, and the same correspondence (setting of access right, etc.) is applied.

The related document detection module 135 is connected to the operation monitoring recording module 140. The related document detection module 135 detects a related document of the phase document based on the information acquired by the operation monitoring recording module 140. When a document for which a document type is not set is displayed and a phase document is updated at the same time or a phase document is referenced, a document for which a document type is not set is displayed as a related document (second Document, corresponding to the fourth document). That is, the second document related to the first document is detected based on the operation history for the first document. Also, a fourth document related to the third document is detected based on the operation history for the third document.
The operation monitoring recording module 140 is connected to the related document detection module 135, the operation history DB 145, and the related information operation history DB 150. The operation monitoring recording module 140 monitors and records in real time which operation the user is performing. For example, after a document is displayed, a process that is closed is also monitored. When the operation target document is a phase document, the related document information detected by the related document detection module 135 is stored in the related information operation history DB 150.

The operation history DB 145 is connected to the operation monitoring recording module 140, the related information operation history DB 150, and the related document access right automatic control module 160. The operation history DB 145 is a DB that records operation information for a document. Consists of existing technology.

Apply.
The document life cycle monitoring module 165 monitors whether a phase transition occurs for the phase document.

  The access pattern model generation module 170 defines, as an “access pattern model”, a model that represents the frequency status of operations for all phase documents in which the document life cycle is completed with the same document type, and generates the model. An access pattern model of display operation for phase document / update operation for phase document is generated. That is, when the first document shifts to the phase, a third document that is the same type as the first document and has already completed the document life cycle is detected. Then, based on the operation history of the third document, an access pattern model of the operation history is generated. For example, the access pattern model may be generated based on the number of operations in time series or the time during which a document is opened.

The access pattern feature determination module 175 determines the similarity with the access pattern in the phase document for the access pattern model generated by the access pattern model generation module 170. That is, the ratio of the difference between the access pattern model and the operation history of the first document and the third document is calculated.
The related document access right determination module 180 predicts how much the related document of the phase document in which the phase shift has occurred is used after the phase shift, and determines an access right to be applied to the related document. Based on the determination result, the access right changing module 120 is controlled to change the access right. That is, the access right of the second document is changed based on the access right of the fourth document. More specifically, among the fourth documents, the fifth document whose number of accesses is less than or less than a predetermined value in the phase transition of the third document corresponding to the fourth document is detected. . Then, the operation history of the fifth document and the operation history of the second document are compared to extract a similar second document, and the access right of the second document is changed to inaccessible. May be. The operation history here is mainly the number of accesses.

In step S208, the related document detection module 135 determines whether the operation to the phase document is reference or writing. If the operation is reference or writing, the process proceeds to step S210. Otherwise, the process proceeds to step S216. . That is, if it is a phase document, the process is transferred to the related document detection module 135, and it is determined whether the operation on the phase document is a display operation or an update operation. For other operations, operation information is recorded in the operation history DB 145.
In step S210, the related document detection module 135 determines whether or not there is a document other than the phase document that has not been closed. If there is, the process proceeds to step S212. Otherwise, the process proceeds to step S216. That is, in the case of a display operation or an update operation, it is confirmed whether there is a document that is displayed by a user other than the phase document on the same machine (a closing operation is not performed after the display operation). If it does not exist, the operation information is recorded in the operation history DB 145.

In step S212, the related document detection module 135 acquires document information other than the phase that is not closed.
In step S214, the operation monitoring recording module 140 records the operation information in the related information operation history DB 150. That is, if it is determined in step S210 that the document exists, the corresponding document information is acquired and recorded in the related information operation history DB 150 together with the phase document information as a related document of the phase document.
In step S216, the operation monitoring recording module 140 records the operation information in the operation history DB 145.

In step S1004, the related document access right determination module 180 applies the difference ratio (ratio) with the access pattern model of the phase document to which the related document is linked (associated) to the related document access status (specifically). Multiply it).
In step S1006, the related document access right determination module 180 applies (specifically, multiplies) the difference ratio (ratio) with the access pattern model in the phase-shifted document to the related document access status.
In step S1008, the related document access right determination module 180 compares the access statuses of the related documents in the completed phase document and the phase-shifted document, and calculates an access status difference amount. In this way, the similarity ratio is calculated.
In step S <b> 1010, the related document access right determination module 180 determines a related document for changing the access right and the access right from the difference amount and the access right setting to be applied. Then, the access right of the related document is changed through the access right change module 120 (see [5. Calculation] in FIG. 22).

In the following, description will be made on generation of an access pattern model and determination of an access right to be applied to a related document.
For example, a document storage table 1100 is stored in the document storage DB 115. FIG. 11 is an explanatory diagram showing an example of the data structure of the document storage table 1100. The document storage table 1100 has a document type column 1110, a document name column 1120, an access right column 1130, and a phase column 1140. The document type column 1110 stores the document type. The document name column 1120 stores a document name (information that can uniquely identify the document in the present embodiment). The access right column 1130 stores access rights (users, groups, etc. having access rights such as editing and deletion). The phase column 1140 stores the current phase in the document. A document whose document type column 1110 is blank is a document other than the phase document that does not need to be managed in the document life cycle.

  For example, a phase table 1200 is stored in the document life cycle DB 130. FIG. 12 is an explanatory diagram showing an example of the data structure of the phase table 1200. The phase table 1200 has a phase name column 1210 and the like. In the phase name column 1210 and the like in the phase table 1200, steps for documents defined in the document life cycle are set. Specifically, it is the content to be performed on the document.

  The document life cycle DB 130 stores, for example, a document life cycle table 1300. FIG. 13 is an explanatory diagram showing an example of the data structure of the document life cycle table 1300. The document life cycle table 1300 has a document type column 1310, a phase column 1320, and an order column 1330. The document type column 1310 stores the document type. The phase column 1320 stores a phase. The order column 1330 stores the order in the document life cycle to which the document of the document type is applied. That is, the document life cycle table 1300 sets a plurality of phases to be performed on the document for each document type.

  For example, an operation history table 1400 is stored in the operation history DB 145. FIG. 14 is an explanatory diagram showing an example of the data structure of the operation history table 1400. The operation history table 1400 includes an operation date / time column 1410, an operator column 1420, a target document name column 1430, and an operation column 1440. The operation date / time column 1410 stores the date and time (year, month, day, second, second or less, or a combination thereof) when the operation was performed. The operator column 1420 stores the user who performed the operation (information that can uniquely identify the user according to the present embodiment). The target document name column 1430 stores the document name of the document to be operated. The operation column 1440 stores operations. That is, the operation history table 1400 records operation information such as operation date / time, operator, target document name, and operation content for the document stored in the document storage table 1100 (see [0. Record] in FIG. 22).

FIG. 15 is a graph illustrating an example of the number of operations when a phase shift occurs. The vertical axis represents the number of operations such as display operation and update operation, and the horizontal axis represents time series. The solid line graph indicates the number of phase document update operations, and the dotted line graph indicates the number of phase document display operations.
The state of the phase target document is monitored by the document life cycle monitoring module 165, and the phase transition of the phase document α “XX project contract” occurs (the phase document α “XX project contract” in FIG. 22). Reference), a document having the same document type “contract” and having the document life cycle completed is acquired.
Here, it is assumed that two phase documents β “△△ case contract” and γ “□□ case contract” are applicable.
The number of displays and the number of updates for the two-phase document are acquired from the operation history table 1400 (see [1. Extraction] in FIG. 22).

From the acquired document information, a moving average model of display and update times is created for each phase document.
After that, in the model of display and update count, the scale is changed to a scale with the maximum value of each operation being 1, and divided into N equal parts set in advance for each phase. Here, it is divided into 10 equal parts and normalized.
The average access pattern of the phase document is calculated in the same phase, and an access pattern model for the entire document life cycle of the phase document of the same document type as the phase transition document is created (see [2. Create] in FIG. 22).
Note that βRfn, βWfn, γRfn, and γWfn are defined as follows.
Number of n-divided displays in phase f of phase document β: βRfn
Number of updates equally divided into n in phase f of phase document β: βWfn
The number of n-divided displays in phase f of phase document γ: γRfn
N equally divided updates in phase f of phase document γ: γWfn
Thereafter, values are standardized in each phase, and an access pattern model for the entire document life cycle in the “contract” is created.
FIG. 16 is an explanatory diagram of an example of a process for generating an access pattern model of “contract”. FIG. 16A shows a phase document β, and FIG. 16B shows a time-series transition graph of the number of operations for displaying and updating the phase document γ. In addition, the double-headed arrow below each graph indicates the phase. Phases 1, 2, and 3 of the phase document β are shorter than phases 1, 2, and 3 of the phase document γ, respectively. Phase 4 of the phase document β is a phase document. It is longer than Phase 4 of γ. In order to match both, each phase is divided into n equal parts (here, 10 equal parts).

An example of a mathematical formula for calculating the access pattern model M of the document type a is shown below.
For phase document β and phase document γ:
Number of n-divided displays in phase f: MaRfn = (βRfn + γRfn) / number of phase documents Number of n-divided updates in phase f: MaWfn = (βWfn + γWfn) / number of phase documents Each phase document corresponds to the access pattern model In order to determine the difference, the difference between each phase document and the access pattern model is changed to a scale with the maximum value being 1, and the ratio of the difference is divided into 10 equal units for each phase. calculate.
The phase calculated here is the phase transition document up to the phase before the transition occurred.
An example of the ratio calculation formula is as follows.
For phase document β:
Ratio of the number of n-divided displays in phase f: DβRfn = MaRfn / βRfn
Ratio of the number of updates equally divided into n in phase f: DβWfn = MaWfn / βWfn

FIG. 17 is an explanatory diagram illustrating a processing example for calculating a ratio of a difference from a pattern. The graph of FIG. 17A compares the update operation (dotted line graph) of the phase document β with the update operation (solid line graph) in the access pattern model. The graph of FIG. 17B compares the display operation (dotted line graph) of the phase document β with the display operation (solid line graph) in the access pattern model. Each difference is indicated by a double arrow.
The related document information of the phase transition document is extracted from the related information operation history DB 150, and the ratio is calculated for each operation on the phase document. In the related information operation history DB 150, for example, a related information operation history table 1800 is stored. FIG. 18 is an explanatory diagram showing an example of the data structure of the related information operation history table 1800. The related information operation history table 1800 has an operation date / time column 1810, an operator column 1820, a related document name column 1830, a phase document name column 1840, a document type column 1850, and a phase document operation column 1860. The operation date / time column 1810 stores the date and time when the operation was performed. The operator column 1820 stores the user who performed the operation. The related document name column 1830 stores the document name of the related document. The phase document name column 1840 stores the document name of the corresponding phase document. The document type column 1850 stores the document type of the phase document. The phase document operation column 1860 stores operations for the phase document.
Similarly, the related document information in the phase document having the same document type “contract” as the phase transition document and having the document life cycle completed is extracted, and the ratio is calculated for each operation on the phase document ([[ See 3. Calculation].

Of the related document information in the phase document in which the document life cycle is completed, the related document that does not have access to the related document related to the phase document is extracted in the phase after the transition of the phase transition document ([4 in FIG. 22]. .. Extraction]).
Here, the access statuses of the related document 1 of the phase document β and the related document 3 of the phase document γ are extracted.
After normalizing the access status of each related document in the same unit as when generating the access pattern model, the scale is changed to a scale where the maximum value of each operation is 1. Multiply the ratio of each phase document with the access pattern model.

Specifically, in the divided unit in the access phase to the related document, the normalized “access status of related document 1 of phase document β” is multiplied by “ratio Dβ of phase document β and access pattern model” ( (See the upper part of FIG. 23B "Applying the difference ratio of each phase document to the target related document access status").
Similarly, “access status of related document 3 of phase document γ” is multiplied by “ratio Dγ between phase document γ and access pattern model” (FIG. 23B). (Apply to access status ")
FIG. 19 is an explanatory diagram illustrating a processing example in which the ratio between the phase document β and the access pattern model is applied to the access status of the related document 1. That is, for the graph showing the access status of the related document 1 of the phase document β shown in the example of FIG. 19A, the phase document β and the access pattern model shown in the examples of FIGS. The difference ratio is applied to obtain a graph shown in the example of FIG. 19D (a result of applying the difference ratio to the access status of the related document 1 of the phase document β).
Similarly, the related documents (related document 5 and related document 6) in the phase shift document are also multiplied by “the ratio of the phase document α and the access pattern model” from the access status (FIG. 23 (c) “the phase shift has occurred. Apply document ratio to related document access status ").

Formula examples in the above case are shown below.
1Rfn and 1Wfn for the related document 1 of the phase document β are defined as follows.
Number of n-divided displays in phase f: 1Rfn
N equally divided updates in phase f: 1 Wfn
Then, the display number and the update number in the related document 1 including the phase document ratio are calculated as follows.
Number of displays equally divided into n in phase f: New1Rfn = 1Rfn × DβRfn
Number of updates equally divided into n in phase f: New1Wfn = 1Wfn × DβWfn

The related document access status of the phase-shifted document after application is compared with the related document access status of the phase document that has completed the document life cycle (see FIG. 23 (d) “Compare with Access Status of Related Documents That Have Phase-Shifted”). ).
Here, the access status is compared in the following cases compared.
“Related document 5 of phase document α” and “Related document 1 of phase document β”
・ "Related document 5 of phase document α" and "Related document 3 of phase document γ"
“Related document 6 of phase document α” and “Related document 1 of phase document β”
・ "Related document 6 of phase document α" and "Related document 3 of phase document γ"

FIG. 20 is an explanatory diagram illustrating a processing example for calculating a difference from a pattern. The graph shown in the example of FIG. 20A shows a difference in the number of update operations of the related document 1 of the phase document β and the related document 5 of the phase document α. The graph shown in the example of FIG. The difference in the number of display operations between the related document 1 of the phase document β and the related document 5 of the phase document α is shown.
It is calculated how much difference each difference has in the phase.
An example of the calculation formula is shown below.
For Related Document 1 and Related Document 5 Deviation Value = Σ (| New5Rfn−New1Rfn |)
Here, it is assumed that the calculation result is as follows.
・ "Related document 5 of phase document α" and "Related document 1 of phase document β" → 62
・ "Related document 5 of phase document α" and "Related document 3 of phase document γ" → 15
・ "Related document 6 of phase document α" and "Related document 1 of phase document β" → 26
・ “Related document 6 of phase document α” and “Related document 3 of phase document γ” → 48

If the calculation result is larger than the predetermined threshold (20), it is predicted that the access to the related document will be the same as the pattern in which the access to the related document is lost with the document to be transferred after the phase shift. Change rights.
In the above case, the access right of the related document of the document α that has undergone the phase shift is changed as follows according to the present embodiment (FIG. 23E) Change ”).
・ "Related document 5 of phase document α" → No access right (accessible only to administrators)
・ "Related document 6 of phase document α" → (No change)

As an application example, a plurality of access right settings may be applied according to the calculation result. For example, the application access right determination setting table 2100 shown in FIG. 21 is prepared, and the access right to be applied is set in comparison with the calculation result. The applied access right determination setting table 2100 has a similarity ratio column 2110 and an access right column 2120. The similarity ratio column 2110 stores a similarity ratio. The access right column 2120 stores an access right (changed to the access right in the access right column 2120) applied in the case of the similar ratio. When there are a plurality of access rights to be applied to one related document, an access right having a high similarity ratio is applied.
In the above case, the access right of the related document of the document α that has undergone the phase shift is changed as follows according to the present embodiment.
・ "Related document 5 of phase document α" → None (accessible only to administrators)
・ "Related document 6 of phase document α" → Encryption
