The input / output unit 201 receives information from the control unit 400 and outputs the received information to the user. The input / output unit 201 includes, for example, a keyboard, a mouse, and a microphone, and also includes a monitor, a speaker, and the like. Details of information and instructions received by the input / output unit 201 and details of information output by the input / output unit 201 will be omitted here, and will be described together with description of each related unit.

  Storage unit 300 is connected to control unit 400. The storage unit 300 stores data used for various processes by the control unit 400. The storage unit 300 is, for example, a semiconductor memory device such as a random access memory (RAM), a read only memory (ROM), or a flash memory, or a storage device such as a hard disk or an optical disk. In the example illustrated in FIG. 2, the storage unit 300 includes a document table 301, a document information table 302, a schedule table 303, a location determination table 304, and a determination result table 305.

  The document table 301 stores documents. In the following description, a document is described using a case where a document name that uniquely identifies a document, an updater name that identifies an updater who updated the document, and the version number of the document are added. For example, the document name, the name of the updater, and the version number are added to the document property or as the attribute information of the document. However, the present invention is not limited to this, and the document name, the updater name, and the version number may not be added to the document. For example, a table that stores the document name and the updater name in association with each other may be provided separately from the document table 301. In the second embodiment, the case where the version number is added to the document will be described. However, the present invention is not limited to this, and the version number may not be added to the document. Further, for example, a document to which a version number is added and a document to which a version number is not added may be mixed. The document table 301 may store data in a data format other than documents.

  The document is also referred to as “data”. Hereinafter, a case where a combination of a document name and a version number is used as identification information for uniquely identifying data will be described. However, the present invention is not limited to this, and the identification information may be any information that can uniquely identify the document. For example, only the document name may be used, and the location information indicating the storage location of the document may be used. Any information may be used.

  The document information table 302 stores information about the data group acquired from the document table 301 by the control unit 400. Specifically, information about a document group for which a reference unnecessary document is specified is stored. An example of information stored in the document information table 302 according to the second embodiment will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of information stored in the document information table according to the second embodiment.

  In FIG. 3, “ID” is information for uniquely identifying a document stored in the document information table. “Document name” is the document name of the document stored in the document information table 302. “Storage destination” is information indicating a storage area in which a document is stored. “Version number” is the version number of the document. The “last update date / time” is the update date / time when the document was last updated. An “updater” is an updater who has updated a document. Specifically, the “updater” is an updater who updated the document on the last update date and time. The “similar file search result” is a flag used by the control unit 400. The similar file search result “1” indicates that there is other data having the same identification information but different updaters. For example, this indicates that there is another data with the same document name and version number but different updaters. The similar file search result “2” indicates that there is no other data having the same identification information but different updaters. For example, this indicates that there is no other data with the same document name and version number but different updaters. The similar file search result “0” indicates that it is unknown whether there is any other data having the same identification information but different updaters. For example, the control unit 400 does not search for data having the same document name and version number but different updaters.

  Information stored in the document information table 302 is stored by the control unit 400 and updated by the control unit 400. For example, as will be described later, in the document information table 302, when the information about the data group acquired from the document table 301 is stored, the “similar file search result” is set to “0” by the control unit 400. . Thereafter, the control unit 400 searches the document information table 302 for the presence / absence of data having the same document name and version number but different updaters, and “similar file search result” is included in the information corresponding to the search result. Updated.

  In the example illustrated in FIG. 3, the document information table 302 is associated with the ID “1”, the document name “XX specification”, the storage destination “¥¥ abc ¥ folder 1”, and the version number “1.1”. The last update date “2009/9/30 14:00” and the updater “A” are stored. That is, for example, in the document information table 302, the document name is “XX specification”, the version number is “1.1”, and is stored in “¥¥ abc ¥ folder 1”. “A” is stored as a document updated to “2009/9/30 14:00”. In the example illustrated in FIG. 3, the document information table 302 stores a similar file search result “0” in association with the ID “1”. That is, in the document information table 302, the control unit 400 does not search for other data having the same identification information for identifying data but different updaters for the document associated with the ID “1”. Remember that. The document information table 302 stores other IDs in the same manner. In the example shown in FIG. 3, the document information table 302 shows a case where the document name is “XX specification”, but the present invention is not limited to this. The document is stored in the same manner.

  The schedule table 303 stores location information and date / time of an updater who is a data updater in association with each other. FIG. 4 shows an example of information stored in the schedule table 303 in the second embodiment. FIG. 4 is a diagram illustrating an example of information stored in the schedule table according to the second embodiment. In FIG. 4, “position information” is position information indicating the location of the updater. “Date and time” is the date and time when the updater was present at the location indicated by “position information”.

  In the example shown in FIG. 4, the schedule table 303 associates the updater “A” with the date and time “2009/9/30 10: 00-12: 00” and the location information “project room A meeting room B”. Remember. That is, the schedule table 303 stores that the updater “A” is in “Project Room A Meeting Room B” at “2009/9/30 10: 00-12: 00: 00”.

  In the schedule table 303, for example, position information and date / time are stored by the updater. In the following, description will be given using the case where the specific device 200 acquires the updater's location information using the schedule table 303, but the present invention is not limited to this, and the location information can be obtained using any method. Good to get. For example, when the updater carries a GPS (Global Positioning System) device, the updater's location information can be obtained by using a table storing map of the updater's location information and map information. good. For example, when the updater carries an ID tag and the location information of the updater is managed for each ID tag, the location information of the updater is acquired from a table managed for each ID tag. Also good.

  The location determination table 304 stores the location information of the updater of the data at the update date and time for data included in the first data group that is the data group having the same identification information but different updaters. The location determination table 304 stores information by the control unit 400.

  An example of information stored in the place determination table 304 according to the second embodiment will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of information stored in the place determination table according to the second embodiment. In FIG. 5, “ID” is information for uniquely identifying a document stored in the document information table 302 as in the case of “ID” in FIG. 3. As will be described later, the IDs stored in the location determination table 304 are all or part of the IDs stored in the document information table 302. “Position information” is position information indicating the location of the updater, similarly to the “position information” in FIG. 4. The “location determination result” is a flag used for the control unit 400. The location determination result “1” indicates that there is other data that matches the location information of the data updater at the data update date and time. For example, it indicates that there is another document with the same location information of the updater at the document update date and time. The location determination result “2” indicates that there is no other data that matches the location information of the data updater at the data update date and time. The location determination result “0” indicates that it is unknown whether there is other data that matches the location information of the data updater at the data update date and time. For example, it shows a state where the control unit 400 has not searched for other data that matches the location information of the data updater at the data update date and time.

  In the example illustrated in FIG. 5, the location determination table 304 stores location information “project room A meeting room A” and location determination result “0” in association with ID “2”. That is, the location determination table 304 stores that the location information of the updater at the update date and time is “project room A meeting room A” for the document with ID “2”. Further, the place determination table 304 stores that it is unknown whether there is other data with the position information of the data updater at the data update date / time regarding the document with ID “2”. The document information table 302 stores other IDs in the same manner.

  The determination result table 305 is the data other than the data associated with the latest update date / time among the update dates / times of the data included in the second data group that is the data group with the same position information in the first data group. Information indicating data is stored. That is, the determination result table 305 stores information indicating data that does not need to be referenced. The second data group is a data group in which the location information of the updater at the update date / time is the same among the data included in the first data group.

  An example of information stored in the determination result table 305 according to the second embodiment will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of information stored in the determination result table according to the second embodiment. In FIG. 6, “ID” is information for uniquely identifying a document stored in the document information table 302, similarly to “ID” in FIGS. 3 and 5. The “judgment result” is a flag indicating whether or not the data need not be referred to. Specifically, the determination result “1” indicates that reference is unnecessary. In the example shown in FIG. 6, the case where no information is included is shown as an example when the data is not reference unnecessary.

  In the example illustrated in FIG. 6, the determination result table 305 stores the determination result “1” in association with the IDs “3” and “4”. That is, the determination result table 305 stores that the document with ID “3” and the document with ID “4” do not need to be referred to.

  The control unit 400 is connected to the input / output unit 201 and the storage unit 300. The control unit 400 includes an internal memory that stores a program that defines various processing procedures and the like, and controls various processes. The control unit 400 is an electronic circuit such as an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a central processing unit (CPU), or a micro processing unit (MPU). In the example illustrated in FIG. 2, the control unit 400 includes a target document acquisition unit 401, a duplicate document determination unit 402, and a document output control unit 403.

  The target document acquisition unit 401 acquires a document to be processed from the document table 301 and stores the acquired document information in the document information table 302. For example, the target document acquisition unit 401 acquires all the documents stored in the document table 301 and stores information about the acquired documents in the document information table 302.

  In the example illustrated in FIG. 3, the target document acquisition unit 401 assigns an ID to each document acquired from the document table 301. Then, the target document acquisition unit 401 stores the document name, the document storage destination, the version number, the update date, the updater, and the like in the document information table 302 in association with the assigned ID. At this time, the target document acquisition unit 401 stores the similar file search result “0” in association with the ID. In the example illustrated in FIG. 3, the document name is “Ox specification”.

  Here, the target document acquisition unit 401 acquires a specific document among the documents stored in the document table 301, and stores information about the acquired document in the document information table 302. For example, all the documents stored in the document table 301 correspond to the specific document. Specific documents include, for example, a document with a document name specified by the user, a document in a folder specified by the user, a document whose update date and time is after the date and time specified by the user, and the like. Applicable.

  As described below, the duplicate document determination unit 402 acquires a first data group, acquires position information for each data included in the first data group, and specifies data. Execute. Hereinafter, processing by the duplicate document determination unit 402 will be described in order.

  Processing for acquiring the first data group will be described. The duplicate document determination unit 402 acquires a first data group having the same identification information for identifying data but different data updaters. For example, the duplicate document determination unit 402 acquires a document group having the same combination of document name and version number but different updaters as the first data group. Hereinafter, documents having the same combination of document name and version number but different updaters are also referred to as “similar documents”.

  In the example illustrated in FIG. 3, the duplicate document determination unit 402 selects one ID associated with the similar file search result “0” among the IDs stored in the document information table 302. That is, the duplicate document determination unit 402 selects one ID for which the control unit 400 has not searched for data having the same document name and version number but different updaters. Then, the duplicate document determination unit 402 searches the document information table 302 for similar documents of the document with the selected ID. Here, if there is a similar document, the duplicate document determination unit 402 indicates that there is a similar document with respect to the “similar file search result” of the selected ID and the “similar file search result” of the similar document “ 2 ”is stored. On the other hand, if there is no similar document, the duplicate document determination unit 402 updates the “similar file search result” of the selected ID to “1” indicating that there is no similar document. Here, the duplicate document determination unit 402 acquires the first data group by acquiring the document group in which “2” is stored in the similar file search result. The duplicate document determination unit 402 repeats the process until there is no ID of the similar file search result “0”. That is, the duplicate document determination unit 402 acquires one or more first data groups by executing a process of acquiring the first data group for each combination of document name and version number.

  The first data group acquisition process performed by the duplicate document determination unit 402 will be described with reference to FIG. FIG. 7 is a diagram illustrating the first data group acquisition process performed by the duplicate document determination unit according to the second embodiment. In FIG. 7, reference numeral 501 denotes the document information table 302 in FIG. Reference numeral 502 denotes a document information table 302 after the duplicate document determination unit 402 updates the similar file search result.

  As indicated by reference numeral 501 in FIG. 7, the duplicate document determination unit 402 selects the ID “1” associated with the similar file search result “0”. In the example indicated by reference numeral 501 in FIG. 7, there is no other document with the document name “Ox specification” and the version number “1.1” for the document with ID “1”. Therefore, as indicated by 502 in FIG. 7, the duplicate document determination unit 402 updates the similar file search result with ID “1” from “0” to “1”.

  Further, as indicated by reference numeral 501 in FIG. 7, the duplicate document determination unit 402 selects the ID “2” associated with the similar file search result “0”. Here, in the example indicated by reference numeral 501 in FIG. 7, the document name and version number of ID “2” are the same as the document name and version number of ID “3” and “4”, and the updater of ID “2” Are different from the updaters of ID “3” and “4”, respectively. Therefore, as indicated by 502 in FIG. 7, the duplicate document determination unit 402 updates the similar file search result with IDs “2” to “4” from “0” to “2”. As a result, the duplicate document determination unit 402 acquires IDs “2” to “4” as the first data group.

  Processing for acquiring position information for each piece of data included in the first data group will be described. The duplicate document determination unit 402 acquires, from the schedule table 303, the position information of the updater at the update date and time for each piece of data included in the first data group. Then, the duplicate document determination unit 402 stores the acquired position information in the place determination table 304. For example, the duplicate document determination unit 402 stores the IDs “2” to “4” acquired as the first data group in the location determination table 304 as the location information of the updater at the update date and time. In addition, when the plurality of first data groups are acquired, the duplicate document determination unit 402 acquires, from the schedule table 303, the position information of the updater at the update date and time for each of the acquired plurality of first data groups. .

  A description will be given using the first data group including IDs “2” to “4”. In the example illustrated in FIG. 3, the duplicate document determination unit 402 acquires the last update date “2009/10/1 11:50” and the updater “A” from the document information table 302 for the ID “2”. Then, the duplicate document determination unit 402 uses the last update date “2009/10/1 11:50” and the updater “A” as keys, and in the example shown in FIG. Acquire “Conference Room A”. In other words, the duplicate document determination unit 402 determines the location information “project room A meeting” indicating the location where the updater “A” was located on “2009/10/1 11:50” when the document with the ID “2” was last updated. Acquire “Room A”. Similarly, the duplicate document determination unit 402 acquires position information for other IDs “3” and “4” included in the first data group. Then, as illustrated in FIG. 5, the duplicate document determination unit 402 stores the acquired position information in association with the IDs “2” to “4” in the location determination table 304, and sets “0” as the location determination result. Store.

  A process for specifying data will be described. The duplicate document determination unit 402 acquires a second data group having the same position information from the data included in the first data group, and the latest update date and time of each data included in the second data group. Specify data other than the data associated with the update date. In addition, when the plurality of first data groups are acquired, the duplicate document determination unit 402 acquires the second data group for each of the acquired first data groups and associates it with the latest update date and time. Identify data other than specified data. If there is no second data group having the same position information, the process for the acquired first data group is terminated without specifying the data.

  A description will be given using the first data group including IDs “2” to “4”. Further, as illustrated in FIG. 5, description will be made using a case where the position information of the IDs “2” to “4” included in the acquired first data group match. In this case, the duplicate document determination unit 402 acquires IDs “2” to “4” as the second data group among the IDs “2” to “4” included in the first data group. Then, the duplicate document determination unit 402 identifies an ID other than the ID associated with the latest update date / time among the IDs “2” to “4”. In the example illustrated in FIG. 3, among the IDs “2” to “4”, the latest update date and time “2009/10/1 11:50” of ID “2” is the latest. In this case, the duplicate document determination unit 402 identifies IDs “3” and “4”. In other words, among the documents identified by IDs “2” to “4” in the document information table 302 in FIG. 3, each document identified by IDs “3” and “4” is specified. Then, as illustrated in FIG. 6, the duplicate document determination unit 402 stores a determination result “1” indicating that the reference unnecessary data is associated with the identified ID in the determination result table 305.

  In addition, as described above, the duplicate document determination unit 402 acquires the above-described first data group and the position information until there is no ID associated with the similar file search result “0”. And the process of specifying data are repeatedly executed. That is, for example, when the data is specified, the duplicate document determination unit 402 determines whether all IDs associated with the similar file search result “0” have been selected. If the duplicate document determination unit 402 determines that it has not been selected, it selects an unselected ID and repeats the process. The duplicate document determination unit 402 is also referred to as a “data group acquisition unit”, “position information acquisition unit”, and “data specification unit”.

  The document output control unit 403 outputs the data specified by the duplicate document determination unit 402. Specifically, the document output control unit 403 refers to the determination result table 305, acquires the ID associated with the determination result “1” indicating that the data is unnecessary to refer to, and information about the acquired ID Is obtained from the document information table 302 and output.

  For example, in the example illustrated in FIG. 6, the document output control unit 403 acquires IDs “3” and “4”, and outputs information about the document identified by the IDs “3” and “4”. An example of information output by the document output control unit 403 according to the second embodiment will be described with reference to FIG. FIG. 8 is a diagram illustrating an example of information output by the document output control unit according to the second embodiment. In the example illustrated in FIG. 8, the document output control unit 403 acquires information about the document specified by the duplicate document determination unit 402 from the document information table 302 and outputs the acquired information as a table. In the example illustrated in FIG. 8, the document output control unit 403 outputs information about the document identified by ID “3” and information about the document identified by ID “4”. However, the present invention is not limited to this, and the document output control unit 403 may output a document by an arbitrary method.

  The specific device 200 may be realized by using an information processing device such as a known personal computer, server, mobile phone, PHS (Personal Handyphone System) terminal, mobile communication terminal, or PDA (Personal Digital Assistant). . For example, the document table 301, the document information table 302, the schedule table 303, the location determination table 304, and the determination result table 305 shown in FIG. Further, the information processing apparatus such as a PDA may be realized by mounting the functions of the target document acquisition unit 401, the duplicate document determination unit 402, and the document output control unit 403 illustrated in FIG.

[Process by specific device]
Next, an example of the flow of processing by the specifying apparatus 200 according to the second embodiment will be described with reference to FIG. FIG. 9 is a flowchart illustrating an example of a flow of processing performed by the specific apparatus according to the second embodiment.

  As shown in FIG. 9, when the processing timing comes (Yes in step S101), the target document acquisition unit 401 acquires a document to be processed from the document table 301 (step S102). For example, the target document acquisition unit 401 acquires all the documents stored in the document table 301. Then, the target document acquisition unit 401 stores information about the acquired document in the document information table 302 (step S103). For example, the target document acquisition unit 401 assigns an ID to a document acquired from the document table 301, and associates the document name, the storage location of the document, the version number, the update date, the updater, etc. with the document information table. 302 is stored. At this time, the target document acquisition unit 401 stores the similar file search result “0” in association with the ID.

  Then, the duplicate document determination unit 402 selects one ID associated with the similar file search result “0” from the IDs stored in the document information table 302 (step S104). That is, the duplicate document determination unit 402 selects one ID for which the control unit 400 has not searched for data having the same identification information but different updaters.

  Then, the duplicate document determination unit 402 searches the document information table 302 for a similar document similar to the document with the selected ID (step S105). Here, when there is no similar document (No in step S106), the duplicate document determination unit 402 updates the “similar file search result” of the selected ID to “1” indicating that there is no similar document ( Step S107). In the example indicated by reference numeral 501 in FIG. 7, the case where the duplicate document determination unit 402 selects the ID “1” associated with the similar file search result “0” will be described. In this case, there is no similar document similar to the document with ID “1”, and the duplicate document determination unit 402 updates the similar file search result to “1”. In this case, the duplicate document determination unit 402 next executes step S113 described later.

  On the other hand, when there is a similar document (Yes in step S106), the duplicate document determination unit 402 updates the “similar file search result” of the selected ID and the “similar file search result” of the similar document to “2”. (Step S108). In the example indicated by reference numeral 501 in FIG. 7, the case where the duplicate document determination unit 402 selects the ID “2” associated with the similar file search result “0” will be described. In this case, the documents with ID “3” and “4” are similar to the document with ID “2”, and the duplicate document determination unit 402 sets the similar file search result with IDs “2” to “4” to “2”. Update to

  Here, the document group in which “2” is stored in the similar file search result becomes the first data group. That is, as shown in steps S104 to S108, the duplicate document determination unit 402 acquires the first data group.

  Then, the duplicate document determination unit 402 acquires, from the schedule table 303, updater position information at the update date and time for each piece of data included in the first data group (step S109). For example, the duplicate document determination unit 402 acquires the last update date “2009/10/1 11:50” and the updater “A” from the document information table 302 for the ID “2”. Then, the duplicate document determination unit 402 acquires the location information “project room A meeting room A” from the schedule table 303 using the last update date “2009/10/1 11:50” and the updater “A” as keys. . Similarly, position information is also acquired for other IDs “3” and “4” included in the first data group.

  Then, the duplicate document determination unit 402 acquires a second data group having the same position information among the data included in the first data group (step S110). As shown in FIG. 5, description will be made using a case where the position information of IDs “2” to “4” included in the acquired first data group match. In this case, the duplicate document determination unit 402 acquires IDs “2” to “4” as the second data group among the IDs “2” to “4” included in the first data group.

  Then, the duplicate document determination unit 402 identifies data other than the data associated with the latest update date and time among the update dates and times of each data included in the second data group (step S111). As shown in FIG. 3, among IDs “2” to “4”, the latest update date and time is the latest update date and time “2009/10/1 11:50” of ID “2”. explain. In this case, the duplicate document determination unit 402 identifies IDs “3” and “4”.

  Then, the duplicate document determination unit 402 stores the determination result “305” in the determination result table 305 in association with the specified ID indicating the determination result “1” indicating that reference is unnecessary (step S112).

  Then, the duplicate document determination unit 402 determines whether all IDs associated with the similar file search result “0” have been selected (step S113). If the duplicate document determination unit 402 determines that no selection has been made (No at Step S113), the process returns to Step S104 described above and repeats the process.

  On the other hand, when it is determined that the duplicate document determination unit 402 has selected (Yes at step S113), the document output control unit 403 outputs the data specified by the duplicate document determination unit 402 (step S114). For example, in the example shown in FIG. 6, the document output control unit 403 acquires IDs “3” and “4”, and as shown in FIG. 8, information about the document identified by the IDs “3” and “4” is obtained. Output.

  Note that the processing procedure described above is not limited to the above order, and may be changed as appropriate within a range that does not contradict the processing content. For example, in the example shown in FIG. 9, the case where data is specified every time the first data group is acquired is shown as an example, but the present invention is not limited to this. For example, first, one or a plurality of first data groups may be acquired together and the subsequent processing may be executed.

[Effect of Example 2]
As described above, according to the second embodiment, the specifying device 200 stores the location information and time of an updater who is a data updater in association with each other. Then, the specifying device 200 acquires a first data group having the same identification information for identifying data but different data updaters. Then, the specifying device 200 acquires the location information of the data updater at the update date and time of the data included in the first data group. Then, the specifying device 200 acquires the second data group in which the position information matches, and the data other than the data associated with the latest update date and time among the update dates and times of the data included in the second data group. Identify. Then, the specifying device 200 outputs the specified data. As a result, according to the specifying device 200, it is possible to appropriately specify data that does not require reference. For example, according to the specifying device 200, it is possible to specify data that does not require reference even in a situation where the version number is not managed. For example, according to the specifying device 200, a document that does not have text data that matches the text data of a document to be referred to can be specified as reference-free data if reference is not required.

For example, when the updater carries a GPS (Global Positioning System) device, the location information of the updater is acquired by using a GPS log table storing map of the updater's location information and map information. May be. That is, the latitude / longitude information associated with the update date / time may be acquired from the GPS log table, and the position information corresponding to the acquired latitude / longitude information may be acquired from the map information. Each time an updater inputs / outputs a room or building using an ID tag, the log is stored in the input / output log table in association with the input / output time, and the input / output log table is used. Thus, the position information may be acquired and used.

[Version number]
Further, for example, in the above-described embodiment, the case where the combination of the document name and the version number is used as the identification information has been described as an example. However, the present invention is not limited to this, and the version number may not be used. Alternatively, any information may be combined and used as identification information.

  Further, each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution / integration of each device is not limited to the one shown in the figure, and all or a part of the distribution / integration may be functionally or physically distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. For example, referring to FIG. 2, the storage unit 300 may be connected as an external device of the specific device 200 via a network.

[Computer]
The various processes described in the above-described embodiments can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. Therefore, in the following, an example of a computer that executes a specific program having the same function as that of the above-described embodiment will be described with reference to FIG. FIG. 10 is a diagram illustrating an example of a computer that executes a specific program according to the second embodiment.

  As illustrated in FIG. 10, the computer 3000 according to the second embodiment includes an operation unit 3001, a microphone 3002, a display 3003, a communication unit 3006, a CPU 3010, a ROM 3011, an HDD (Hard Disk Drive) 3012, and a RAM 3013. Further, the computer 3000 is connected to each other by a bus 3009.

  The ROM 3011 stores a control program that exhibits the same functions as the target document acquisition unit 401, the duplicate document determination unit 402, and the document output control unit 403 illustrated in FIG. That is, as shown in FIG. 10, the ROM 3011 stores a target document acquisition program 3011a, a duplicate document determination program 3011b, and a document output control program 3011c. Note that these programs 3011a to 3011c may be appropriately integrated or separated in the same manner as each component of the specific device 200 shown in FIG.

  Then, the CPU 3010 reads out these programs 3011a to 3011c from the ROM 3011 and executes them. As a result, as shown in FIG. 10, the programs 3011a to 3011c function as a target document acquisition process 3010a, a duplicate document determination process 3010b, and a document output control process 3010c. Each process 3010a to 3010c corresponds to the target document acquisition unit 401, the duplicate document determination unit 402, and the document output control unit 403 shown in FIG.

  The HDD 3012 is provided with a document table 3012a and a schedule table 3012b. Each table 3012a to 3012b corresponds to the document table 301 and the schedule table 303 shown in FIG.

  Then, the CPU 3010 reads out the document table 3012a and the schedule table 3012b and stores them in the RAM 3013. The CPU 3010 executes the specific program using the document data 3013a, document information data 3013b, schedule data 3013c, location determination data 3013d, and determination result data 3013e stored in the RAM 3013.

  However, in the above description, the case where all the processes 3010a to 3010c are always virtually realized on the CPU 3010 is shown. However, the present invention is not limited to this. For example, some processes required for processing among the processes 3010a to 3010c may be virtually realized on the CPU 3010. In other words, not all processes always operate on the CPU 3010, but processes necessary for processing may selectively operate.

  Similarly, the case where both the document table 3012a and the schedule table 3012b are stored in the RAM 3013 is shown. However, the present invention is not limited to this. For example, a part of the tables required for processing out of the document table 3012a and the schedule table 3012b may be stored in the RAM 3013. In other words, not all tables are always stored in the RAM 3013, but tables necessary for processing may be selectively stored.

An example of the configuration of the specifying device 600 according to the fourth embodiment will be described with reference to FIG. FIG. 11 is a block diagram illustrating an example of the configuration of the specific apparatus according to the fourth embodiment. In the example illustrated in FIG. 11, the identification device 600 includes an input / output unit 601, a storage unit 700, and a control unit 800. The input / output unit 601 is connected to the control unit 800. The description of the input / output unit 601 is the same as the description of the input / output unit 201 illustrated in FIG.

  Storage unit 700 is connected to control unit 800. The storage unit 700 stores data used for various processes performed by the control unit 800. The storage unit 700 is, for example, a semiconductor memory device such as a random access memory (RAM), a read only memory (ROM), and a flash memory, or a storage device such as a hard disk or an optical disk. In the example illustrated in FIG. 11, the storage unit 700 includes a document information table 302, a determination result table 305, and an e-mail information table 701. Among these, the description of the document information table 302 and the determination result table 305 illustrated in FIG. 11 is the same as the description of the document information table 302 and the determination result table 305 illustrated in FIG. 2.

  The e-mail information table 701 stores information about the e-mail acquired from the mail server by the control unit 800. Specifically, the e-mail information table 701 includes e-mail ID, transmission date and time, information indicating the sender, information indicating the recipient, title, text, attached file name, and opening information indicating whether or not the file has been opened. Remember. The e-mail information table 701 is an example of a “message information storage unit”. An e-mail is an example of a “message”.

  An example of information stored in the e-mail information table according to the fourth embodiment will be described with reference to FIG. FIG. 12 is a diagram illustrating an example of information stored in the electronic mail information table according to the fourth embodiment. In FIG. 12, “Mail ID” is identification information for uniquely identifying an electronic mail. For example, the “mail ID” is given by the control unit 800 when information related to the email is stored in the email information table 701. “Transmission date and time” is information indicating the date and time when the electronic mail is transmitted. “Sender” is information indicating the person who sent the e-mail. For example, “sender” is the sender's transmission address or user name. “Recipient” is information indicating the person who received the e-mail. For example, “recipient” is the recipient's reception address or user name. “Open” is open information indicating whether or not the recipient opened the electronic mail. For example, opening “1” indicates that each recipient has opened an email, and opening “0” indicates that any recipient has not opened the email. “Title” is the title of the e-mail. The “text” is the text of the e-mail. “Attached file name” is the file name of the file attached to the e-mail. The information stored in the e-mail information table 701 is, for example, information acquired and stored by the control unit 800 from a mail server that manages e-mail communication.

  Hereinafter, a case where the mail ID is used as the identification information of the e-mail will be described as an example, but the present invention is not limited to this. As the identification information, any information may be used as long as the information can uniquely identify the electronic mail. For example, e-mail transmission date and time may be used as the identification information.

  In the example shown in FIG. 12, the e-mail information table 701 is associated with the mail ID “B1055”, the transmission date and time “2009/10/1 10:55”, the sender “B”, and the recipients “A, C ”is stored. In addition, the e-mail information table 701 is associated with the mail ID “B1055”, the opening “1”, the title “...”, The text “...”, And the attached file name “. Remember. That is, the e-mail information table 701 stores that the e-mail with the mail ID “B1055” is an e-mail transmitted from the sender B to the recipients A and C on “2009/10/1 10:55”. To do. In the e-mail information table 701, the e-mail with the mail ID “B1055” is opened by the recipients A and C, and the title “...”, The text “...”, And the attached file name “. It is memorized that it is an e-mail with the content.

  In the example illustrated in FIG. 12, the email information table 701 is associated with the email ID “C1058”, the transmission date and time “2009/10/1 10:58”, the sender “C”, and the recipient “C”. A, B "is stored. In addition, the e-mail information table 701 is associated with the mail ID “C1058”, with an opening “0”, a title “...”, A text “...”, And an attached file name “. Remember. That is, the e-mail information table 701 stores that the e-mail with the mail ID “C1058” is an e-mail transmitted from the sender C to the receivers A and B on “2009/10/1 10:58”. To do. Further, in the e-mail information table 701, the e-mail with the mail ID “C1058” is not opened by the recipient A or B, and the title “...”, The text “...”, The attached file name “. "Is stored as an e-mail with the content". " The e-mail information table 701 also stores other e-mails in the same manner.

  The control unit 800 is connected to the input / output unit 601 and the storage unit 700. The control unit 800 includes an internal memory that stores a program that defines various processing procedures and the like, and controls various processes. The control unit 800 is an electronic circuit such as an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a central processing unit (CPU), or a micro processing unit (MPU). In the example illustrated in FIG. 11, the control unit 800 includes a document acquisition unit 801, an e-mail acquisition unit 802, a specification unit 803, and an output control unit 804.

  The document acquisition unit 801 acquires a first data group having the same identification information for identifying data but different data updaters. The description of the process in which the document acquisition unit 801 acquires the first data group is the same as the description of the process in which the duplicate document determination unit 402 illustrated in FIG. 2 acquires the first data group. The document acquisition unit 801 is an example of a “data group acquisition unit”.

  For each piece of data included in the first data group, the e-mail acquisition unit 802 transmits a message communicated between the data updaters within a predetermined time from the update date and time of the latest data in the first data group. Is obtained from the e-mail information table 701. For example, the e-mail acquisition unit 802 stores information related to e-mails that satisfy the following conditions for each of the documents with IDs “2”, “3”, and “4” acquired as the first data group. Get from. That is, the e-mail acquisition unit 802 acquires, from the e-mail information table 701, information related to an e-mail that is a common e-mail communicated between updaters and communicated within a predetermined time. Then, the e-mail acquisition unit 802 acquires an e-mail in which the information related to the acquired e-mail includes a document name and information indicating that the file has been opened. The predetermined time is, for example, 1 hour. The predetermined time is not limited to this example, and a person who uses the specific device 600 may set an arbitrary value. The e-mail acquisition unit 802 is an example of a “message information acquisition unit”.

  Description will be made using the first data group including IDs “2”, “3”, and “4”. In the example illustrated in FIG. 3, the latest update date and time of the documents “ID” “2”, “3”, and “4” having the same document identification information and different updaters is the last update date and time of ID “2”. “2009/10/1 11:50”. In this case, the e-mail acquisition unit 802 updates the updaters “A”, “B”, and “C” and the last update date and time of the ID “2” for the documents with the IDs “2”, “3”, and “4”. “2009/10/1 11:50” is acquired from the document information table 302. Then, the e-mail acquisition unit 802 uses the updaters “A”, “B”, and “C” and the last update date and time “2009/10/1 11:50” as keys in the example shown in FIG. / 10/1 11:50 "and the e-mails that the updaters" A "," B ", and" C "communicated within one hour before are acquired. That is, the duplicate document determination unit 402 includes updaters “A”, “B”, and “C” in “sender” or “recipient”, and transmits them on the transmission date “2009/10/1 10:55”. The acquired email IDs “B1055” and “C1058” are acquired from the email information table 701. The duplicate document determination unit 402 then opens the document “1” in the emails with the mail IDs “B1055” and “C1058”, and the document is included in any of the “title”, “text”, or “attached file name”. An e-mail containing the name “XX specification” is acquired. In the example illustrated in FIG. 12, it is assumed that the document name is included in the “title”, “text”, or “attached file name” of the email with the email ID “B1055”. In this case, the e-mail acquisition unit 802 acquires the e-mail with the mail ID “B1055” from the e-mail information table 701.

  The identifying unit 803 acquires, for each data included in the first data group, a second data group in which messages communicated between data updaters match. Then, the specifying unit 803 specifies data other than data associated with the latest update date and time among the update dates and times of each data included in the second data group. If there is no second data group in which the messages communicated between the data updaters match, the processing for the acquired first data group is terminated without specifying the data.

  Description will be made using the first data group including IDs “2”, “3”, and “4”. Here, as shown in FIGS. 3 and 12, for each of the IDs “2”, “3”, and “4”, the mail IDs “A”, “B”, and “C” communicated between the updaters “A”, “B”, and “C”. The case where the electronic mail “B1055” is acquired from the electronic mail information table 701 will be described. In this case, the identifying unit 803 acquires documents with IDs “2”, “3”, and “4” associated with the email with the mail ID “B1055” as the second data group. The identifying unit 803 identifies an ID other than the ID associated with the latest update date / time among the IDs “2”, “3”, and “4”. In the example shown in FIG. 3, among the IDs “2”, “3” and “4”, the latest update date and time “2009/10/1 11:50” of the ID “2” is the latest. . In this case, the specifying unit 803 specifies the IDs “3” and “4”. In other words, among the documents identified by IDs “2”, “3”, and “4” in the document information table 302 of FIG. 3, each document identified by IDs “3” and “4” is specified. Then, as illustrated in FIG. 6, the specifying unit 803 stores a determination result “1” indicating that the data is reference unnecessary in association with the specified ID in the determination result table 305.

  In addition, the document acquisition unit 801, the e-mail acquisition unit 802, and the specification unit 803 acquire the first data group until the ID of the similar file search result corresponding to “0” disappears, and the e-mail. The process of acquiring and the process of specifying data are repeatedly executed. That is, for example, when the document acquisition unit 801 specifies data, the document acquisition unit 801 determines whether all IDs associated with the similar file search result “0” have been selected. If the document acquisition unit 801 determines that the document has not been selected, the document acquisition unit 801 selects an unselected ID and repeats the process.

  The output control unit 804 outputs the data specified by the specifying unit 803. The description of the process of outputting data by the output control unit 804 is the same as the description of the process of outputting data by the document output control unit 403 shown in FIG. The output control unit 804 is an example of an “output unit”.

  The specific device 600 may be realized by using an information processing device such as a known personal computer, server, mobile phone, PHS (Personal Handyphone System) terminal, mobile communication terminal, or PDA (Personal Digital Assistant). . For example, the document information table 302, the email information table 702, and the determination result table 305 shown in FIG. In addition, it can be realized by mounting the functions of the document acquisition unit 801, the email acquisition unit 802, the identification unit 803, and the output control unit 804 shown in FIG. good.

[Process by specific device]
Next, an example of the flow of processing performed by the identifying apparatus 600 according to the fourth embodiment will be described with reference to FIG. FIG. 13 is a flowchart illustrating an example of a process flow performed by the specific apparatus according to the fourth embodiment.

  As illustrated in FIG. 13, when the processing timing comes (Yes in step S <b> 201), the document acquisition unit 801 selects an ID associated with the similar file search result “0” among the IDs stored in the document information table 302. One is selected (step S202). That is, the document acquisition unit 801 selects one ID that is not searched by the control unit 800 from data having the same identification information but different updaters.

  Then, the document acquisition unit 801 searches the document information table 302 for a similar document similar to the document with the selected ID (step S203). Here, when there is no similar document (No at Step S204), the document acquisition unit 801 updates the “similar file search result” of the selected ID to “1” indicating that there is no similar document (Step S204). S205). Then, the document acquisition unit 801 executes step S212 described later.

  On the other hand, when there is a similar document (Yes in step S204), the document acquisition unit 801 updates the “similar file search result” of the selected ID and the “similar file search result” of the similar document to “2” ( Step S206). Here, the document group in which “2” is stored in the similar file search result becomes the first data group. That is, as shown in steps S202 to S206, the document acquisition unit 801 acquires the first data group.

  Then, the e-mail acquisition unit 802 acquires e-mails communicated between updaters from the e-mail information table 701 within one hour from the last update date and time for each data included in the first data group ( Step S207). For example, the e-mail acquisition unit 802 acquires the last update date “2009/10/1 11:50” and the updater “A” from the document information table 302 for the ID “2”. Similarly, the e-mail acquisition unit 802 acquires the last update date and time and the updater from the document information table 302 for the other IDs “3” and “4” included in the first data group. Then, the e-mail acquisition unit 802 uses the updaters “A”, “B”, and “C” and the last update date and time “2009/10/1 11:50” as keys, and the updaters “A” and “B”. And a common e-mail communicated by “C”. In the example shown in FIG. 12, the e-mail acquisition unit 802 acquires e-mails communicated by updaters “A”, “B”, and “C” one hour before “2009/10/1 11:50”. To do.

  Then, the e-mail acquisition unit 802 acquires an e-mail in which the information related to the acquired e-mail includes the document name and the information indicating that it has been opened (step S208). For example, the e-mail acquisition unit 802 opens “1” among the e-mails with the mail IDs “B1055” and “C1058” shown in FIG. 12, and “title”, “text”, or “attached file name”. E-mail including the document name “XX specification” is acquired. In the example illustrated in FIG. 12, it is assumed that the document name “XX specification” is included in the “title”, “text”, or “attached file name” of the e-mail with the mail ID “B1055”. In this case, the e-mail acquisition unit 802 acquires the e-mail with the mail ID “B1055” from the e-mail information table 701.

  Then, the specifying unit 803 acquires a document associated with the e-mail as a second data group (step S209). For example, as shown in FIGS. 3 and 12, for the IDs “2”, “3”, and “4”, the mail ID “B1055” communicated between the updaters “A”, “B”, and “C”. The case where the e-mail is acquired from the e-mail information table 701 will be described. In this case, the identifying unit 803 acquires documents with IDs “2”, “3”, and “4” associated with the email with the mail ID “B1055” as the second data group.

  Then, the specifying unit 803 specifies data other than the data associated with the latest update date and time among the update dates and times of each data included in the second data group (step S210). As shown in FIG. 3, among the IDs “2”, “3”, and “4”, the latest update date / time “2009/10/1 11:50” of ID “2” is the latest. The case will be described. In this case, the specifying unit 803 specifies the IDs “3” and “4”.

  Then, the specifying unit 803 stores the determination result “1” indicating that the data is unnecessary to reference in the determination result table 305 in association with the specified ID (step S211).

  Then, the document acquisition unit 801 determines whether all IDs associated with the similar file search result “0” have been selected (step S212). If the document acquisition unit 801 determines that the document has not been selected (No at Step S212), the process returns to Step S202 described above and repeats the process.

  On the other hand, when it is determined that the document acquisition unit 801 has selected (Yes at Step S212), the output control unit 804 outputs the data specified by the specifying unit 803 (Step S213). For example, in the example illustrated in FIG. 6, the output control unit 804 acquires the IDs “3” and “4”, and as illustrated in FIG. 8, information about the document identified by the IDs “3” and “4”. Is output.

  In the above-described processing procedure, the processing for specifying data that does not need to be referenced using the position information described in the second embodiment may be executed, and then the processing for specifying data that does not need to be referenced may be executed using a message. . That is, the specifying device 600 may further include the schedule table 303, the location determination table 304, and the duplicate document determination unit 402 shown in FIG. An example of the flow of processing performed by the identifying apparatus 600 according to the fourth embodiment will be described with reference to FIG. FIG. 14 is a flowchart illustrating an example of a process flow performed by the specific apparatus according to the fourth embodiment.

  As shown in FIG. 14, when the processing timing comes (Yes at Step S <b> 301), the document acquisition unit 801 selects an ID associated with the similar file search result “0” among the IDs stored in the document information table 302. One is selected (step S302).

  Then, the document acquisition unit 801 searches the document information table 302 for similar documents similar to the document with the selected ID (step S303). Here, when there is no similar document (No at Step S304), the document acquisition unit 801 updates the “similar file search result” of the selected ID to “1” indicating that there is no similar document (Step S304). S305). Then, the document acquisition unit 801 executes step S314 described later.

  On the other hand, when there is a similar document (Yes at step S304), the document acquisition unit 801 updates the “similar file search result” of the selected ID and the “similar file search result” of the similar document to “2” ( Step S306). Here, the document group in which “2” is stored in the similar file search result becomes the first data group. That is, as shown in steps S302 to S306, the document acquisition unit 801 acquires the first data group.

  Then, the duplicate document determination unit 402 acquires, from the schedule table 303, updater position information at the update date and time for each piece of data included in the first data group (step S307). The duplicate document determination unit 402 acquires a second data group having the same position information among the data included in the first data group (step S308).

  Then, the e-mail acquisition unit 802 acquires e-mails communicated between the updaters from the e-mail information table 701 within one hour from the last update date / time for each data other than the second data group (step S1). S309). The e-mail acquisition unit 802 acquires an e-mail in which the information related to the acquired e-mail includes the document name and information indicating that it has been opened (step S310).

  Then, the specifying unit 803 acquires a document associated with the email as a third data group (step S311). The specifying unit 803 specifies data other than the data associated with the latest update date / time from the second data group and the third data group (step S312). The specifying unit 803 stores a determination result “1” indicating that the data is unnecessary to reference in the determination result table 305 in association with the specified ID (step S313).

  Then, the document acquisition unit 801 determines whether all IDs associated with the similar file search result “0” have been selected (step S314). If the document acquisition unit 801 determines that no selection has been made (No at Step S314), the process returns to Step S302 described above and repeats the process.

  On the other hand, when it is determined that the document acquisition unit 801 has selected (Yes at Step S314), the output control unit 804 outputs the data specified by the specifying unit 803 (Step S315).

  In FIG. 14, the case has been described in which the specifying device 600 executes the process of specifying the reference unnecessary data using the message after executing the process of specifying the reference unnecessary data using the position information. It is not limited to. For example, the specifying device 600 may execute a process of specifying data that does not need to be referenced using position information after executing a process of specifying data that does not need to be referenced using a message. Specifically, after executing steps S201 to S209 in FIG. 13, the specifying apparatus 600 executes steps S109 to S110 in FIG. 9 for data other than the second data group, and sets the acquired data group to the third data group. Data group. Thereafter, the specifying device 600 may specify data that does not need to be referenced by executing steps S312 to S315 of FIG. Further, for example, the identifying apparatus 600 may execute in parallel a process for identifying unnecessary data using position information and a process for identifying unnecessary data using a message. Specifically, the identifying apparatus 600 first executes steps S101 to S108 in FIG. 9 to acquire a first data group. Subsequently, the identification device 600 executes steps S109 to S110 in FIG. 9 and steps S207 to S209 in FIG. 13 in parallel for each data included in the first data group. Then, the identifying device 600 identifies data that has not been acquired in steps S109 to S110 or steps S207 to S209 among the data included in the first data group, and then executes steps S112 to S114 in FIG. Also good.

  Note that the processing procedure described above is not limited to the above order, and may be changed as appropriate within a range that does not contradict the processing content. For example, in the example shown in FIGS. 13 and 14, the case where data is specified every time the first data group is acquired is shown as an example, but the present invention is not limited to this. For example, in the processing procedure described above, one or a plurality of first data groups may be acquired together and the subsequent processing may be executed. Further, for example, step S208 and step S310, which are processes for obtaining an e-mail containing information indicating that the document name and the document have been opened, are not necessarily executed. That is, step S208 and step S310 may not be executed. Further, in the above-described processing procedure, in step S208 or step S310, only the process of acquiring an e-mail including a document name may be executed, and the process of acquiring an e-mail including information indicating that the document has been opened. You may only run.

[Effect of Example 4]
As described above, according to the fourth embodiment, the specifying device 600 updates the data updater within a predetermined time from the first data group in which the identification information for identifying the data is the same and the data updater is different. The second data group in which the messages communicated between the two match is acquired. Then, the specifying device 600 specifies data other than the data associated with the latest update date and time among the update dates and times of the data included in the second data group, and outputs the specified data. As a result, according to the specifying device 600, it is possible to appropriately specify data that does not require reference. For example, according to the specifying device 600, it is possible to specify data that does not require reference even in a situation where the version number is not managed. For example, according to the specifying device 600, a document that does not have text data that matches the text data of the document to be referred to can be specified as reference-free data if reference is not required.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in other embodiments besides the above-described embodiments. Therefore, other embodiments will be described below.

[Output data that does not require reference]
For example, in the above-described embodiments, the case where data that does not require reference is output has been described. However, the present invention is not limited to this, and data that requires reference may be output. Specifically, the identification device 600 may output data associated with the latest update date and time among the update dates and times of each data included in the second data group.

[Output mode]
Further, for example, in the above-described embodiment, as illustrated in FIG. 8, the case has been described in which the specific device 600 outputs various pieces of information about data. However, the present invention is not limited to this, and the data itself is not limited. You may make it output. For example, the specifying device 600 may output the document itself.

For example, communication means such as an IP phone or a messenger that can acquire a communication record may be used as the message.

[Version number]
Further, for example, in the above-described embodiment, the case where the combination of the document name and the version number is used as the identification information has been described as an example. However, the present invention is not limited to this, and the version number may not be used. Alternatively, any information may be combined and used as identification information.

[System configuration]
Also, among the processes described in this embodiment, all or part of the processes described as being performed automatically can be performed manually, or the processes described as being performed manually can be performed. All or a part can be automatically performed by a known method. In addition, the processing procedures, control procedures, specific names, and information including various data and parameters shown in the above-mentioned documents and drawings (FIGS. 11 to 14 etc.) are arbitrarily changed unless otherwise specified. can do. For example, the e-mail information table 701 shown in FIG. 12 does not store the title, the body, and the attached file name, but may store these information as text data in one item.

  Further, each component of each illustrated apparatus is functionally conceptual, and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution / integration of each device is not limited to the one shown in the figure, and all or a part of the distribution / integration may be functionally or physically distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. For example, referring to FIG. 11, the storage unit 700 may be connected as an external device of the specific device 600 via a network.

[Computer]
The various processes described in the above-described embodiments can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. Therefore, in the following, an example of a computer that executes a specific program having the same function as that of the above-described embodiment will be described with reference to FIG. FIG. 15 is a diagram illustrating an example of a computer that executes a specific program according to the fourth embodiment.

  As illustrated in FIG. 15, the computer 4000 according to the fourth embodiment includes an operation unit 4001, a microphone 4002, a display 4003, a communication unit 4006, a CPU 4010, a ROM 4011, an HDD (Hard Disk Drive) 4012, and a RAM 4013. Further, the computer 4000 is connected to each part by a bus 4009.

  The ROM 4011 stores a control program that exhibits functions similar to those of the document acquisition unit 801, the e-mail acquisition unit 802, the specifying unit 803, and the output control unit 804 illustrated in FIG. That is, as shown in FIG. 15, the ROM 4011 stores a document acquisition program 4011a, an e-mail acquisition program 4011b, a specific program 4011c, and an output control program 4011d. Note that these programs 4011a to 4011d may be integrated or separated as appropriate, as with each component of the specific device 600 shown in FIG.

  The CPU 4010 reads these programs 4011a to 4011d from the ROM 4011 and executes them. As a result, as shown in FIG. 15, the programs 4011a to 4011d function as a document acquisition process 4010a, an e-mail acquisition process 4010b, a specific process 4010c, and an output control process 4010d. Each process 4010a to 4010d corresponds to the document acquisition unit 801, the e-mail acquisition unit 802, the specifying unit 803, and the output control unit 804 shown in FIG.

  The HDD 4012 is provided with a document information table 4012a and an e-mail information table 4012b. Each table 4012a to 4012b corresponds to the document information table 302 and the e-mail information table 701 shown in FIG.

  Then, the CPU 4010 reads out the document information table 4012a and the email information table 4012b and stores them in the RAM 4013. The CPU 4010 executes the specific program using the document information data 4013a, the e-mail information data 4013b, and the determination result data 4013c stored in the RAM 4013.

  However, in the above description, the case where all the processes 4010a to 4010d are always virtually realized on the CPU 4010 is shown. However, the present invention is not limited to this. For example, some processes necessary for processing among the processes 4010a to 4010d may be virtually realized on the CPU 4010. In other words, not all processes always operate on the CPU 4010, but processes necessary for processing may selectively operate.

  Similarly, the case where both the document information table 4012a and the e-mail information table 4012b are stored in the RAM 4013 is shown. However, the present invention is not limited to this. For example, a part of the table necessary for processing out of the document information table 4012a and the e-mail information table 4012b may be stored in the RAM 4013. In other words, not all tables are always stored in the RAM 4013, but tables necessary for processing may be selectively stored.
