The present invention relates to a document management method and a document management program.

  When creating a document, it is important to create a document that can be easily understood by a person viewing the document. It is not necessary to describe in detail matters relating to the knowledge possessed by the viewer, but it is necessary to describe matters relating to knowledge that the viewer does not have in detail. For this reason, it is convenient to know beforehand whether or not a document to be created is known to the viewer. Further, when browsing an existing document, it is not necessary to browse a known item, and if only an unknown item can be browsed, the document can be browsed efficiently.

  As a technique for detecting a user who has knowledge about a keyword, Japanese Patent Laid-Open No. 2008-191894 (Patent Document 2) is connected to a plurality of client computers operated by a user via the Internet, and includes a processor, a memory, and an interface. A WEB server comprising: a search history indicating a correspondence between a search keyword and a user who searched the search keyword; a search request including the search keyword is received from the client computer; and from the received search request A search keyword is extracted, a user corresponding to the extracted search keyword is specified based on the search history, and information on the specified user is used as information on a user who has searched the same search keyword in the past. The sender of the received search request WEB server and transmits to the client computer is described.

However, not all search results are successful, and even if the search is successful, the user does not always use the search results. For this reason, although the conventional WEB server can specify the user who performed the same search in the past, there is a problem that the specified user is not necessarily an expert who has knowledge about the keyword.

Here, L is a predetermined threshold value, and is set when the user inputs to the file server 200 in advance. Then, the document selection unit 73 outputs all of the selected L selected documents at the maximum to the access count for each user 75.

  The user-by-user access count totaling unit 75 counts the number of access history information for each user for all the access history information corresponding to each of up to L selected documents input from the document selection unit 73, and Calculate the number of accesses. The number of accesses by user is the number of accesses for each user identification information. Since the access history information includes user identification information, the access history information is classified into users including the same user identification information, and the number of accesses for each user is calculated by counting the number of access history information for each user identification information.

  The user-by-user access count totaling unit 75 rearranges the user-by-user access counts in the descending order of the access counts, and outputs the user identification information with priorities in the descending order of the access counts to the determining unit 81. In addition, when the number of user identification information is N or more, the user-specific access count totaling unit 75 rearranges the user identification information in descending order of the number of user-specific accesses, and identifies the top N user identifications in descending order of the number of user-specific accesses. The information is output to the determination unit 81 as user identification information of the related user. Here, N is a predetermined threshold value, and is set when the user inputs to the file server 200 in advance.

  The user-by-user access count totaling unit 75 outputs the user-by-user access count to the group totaling unit 79. The group totaling unit 79 calculates the number of access times for each group by counting the number of access times for each user for all of the number of access times for each user input from the access frequency totaling unit for each user 75. The access count by group is the access count by group. The group totaling unit 79 refers to the user data 97 and specifies group identification information of a group in which the user of the user identification information is classified. Then, user identification information having the same group identification information is classified into the same group, and the number of accesses by group is calculated. When the number of groups is M or more, the group totaling unit 79 rearranges the groups in the order of the number of accesses by group, and displays the top M group identification information in the order of the number of accesses by group for the group to which the related user belongs. The information is output to the determination unit 81 as group identification information. Here, M is a predetermined threshold value, and is set when the user inputs to the file server 200 in advance.

  The determination unit 81 receives the browsing destination information from the browsing destination information receiving unit 53, receives at most M user identification information from the related user specifying unit 69 as user identification information of the related user, and receives from the related user specifying unit 69. A maximum of N pieces of group identification information are input as group identification information of related groups. When the browsing destination information is user identification information, the determination unit 81 determines whether or not all of the user identification information input as the browsing information is included in the user identification information of the related users. If all the user identification information input as the browsing destination information is included in the user identification information of the related users, it is determined that the keyword is known to all the users of the browsing destination, but if the keyword is not included alone, it is determined to be known. do not do. Further, if the ratio of user identification information included in the user identification information of the related user among the user identification information input as the browsing destination information is equal to or greater than a predetermined value, the keyword is known to some users at the browsing destination. May be known.

  When the browsing destination information is group identification information, the determination unit 81 determines whether the group identification information input as the browsing destination information is included in the group identification information input from the related user specifying unit 69. If the group identification information input as the browsing destination information is included in the group identification information input from the related user specifying unit 69, it is determined that the keyword is known to the browsing destination group, but the keyword is input from the related user specifying unit 69. If it is not included in the group identification information, it is not determined that the information is well known. The determination unit 81 outputs a signal indicating that the keyword is known to the notification unit 55 when determining that the keyword is known to the browsing destination, but is not known when the keyword is not known to the browsing destination. Is output to the notification unit 55.

  When the signal indicating that the keyword is known is input from the determination unit 81, the notification unit 55 notifies the user that the keyword is known. Specifically, when the user inputs characters from the operation unit 207 and creates a document, a message indicating that the keyword is known is displayed on the display unit 206. For example, the message “The viewer is familiar with the items of this headline” is displayed. When the user operates any of the PCs 400 to 402 to create a document, a message indicating that the keyword is known is transmitted to the PC 400 to 402 operated by the user. Thereby, a message is displayed on the PC 400 to 402 operated by the user. A user who sees a message indicating that the keyword is well-known can know that it is not necessary to describe details of the headline after entering the headline during the creation of the document.

<Access processing>
The access operation includes an operation for instructing execution of processing for storing a new document in the HDD 205, an operation for instructing execution of processing for outputting the document 93 stored in the HDD 205, and a change or deletion of the document 93 stored in the HDD 205. Including an operation for instructing execution of processing to be performed. The access operation accepted by the document management unit 67 by the operation unit 207 or the access operation received from any of the PCs 400 to 402 and the MFPs 100, 100A, and 100B is input with operation identification information for identifying the access operation and the access operation. The user identification information for identifying the user who has performed the process and the document identification information for identifying the document 93 stored in the HDD 205 to be processed based on the access operation. The processing for outputting the document includes processing for displaying the document on the display unit 206, processing for transmitting the document by e-mail or FTP via the network I / F 204, and printing out the document by any of the MFPs 100, 100A, and 100B. Processing, and processing to be displayed on a projector or the like.

  For example, if a user who has logged in to the PC 400 inputs an operation for browsing the document 93 stored in the HDD 205 to the PC 400, the PC 400 transmits an access operation indicating that the document 93 is browsed to the file server 200. The file server 200 receives an access operation transmitted from the PC 400 via the network I / F 204. The document management unit 67 receives an access operation from the network I / F 204. In this case, the access operation received from the PC 400 is the document identification information of the document 93, the operation identification information indicating that the operation is an instruction for processing to browse the document 93, and the user identification information of the user who has logged into the PC 400. ,including. If the user who has logged into MFP 100 inputs an operation to print document 93 stored in HDD 205 to MFP 100, MFP 100 transmits an access operation to print document 93 to file server 200. 200 receives an access operation transmitted from the MFP 100 via the network I / F 204. The document management unit 67 receives an access operation from the network I / F 204. In this case, the access operation received from MFP 100 is the document identification information of document 93, the operation identification information indicating that the operation is an instruction to print the document 93, and the user identification information of the user who has logged into MFP 100. ,including.

  The instruction operation reception unit 57 of the document management unit 67 receives an access operation from the operation unit 207 when an access operation is input to the operation unit 207. In addition, when receiving an access operation from any of the PCs 400 to 402 and the MFPs 100, 100 </ b> A, and 100 </ b> B, the instruction operation reception unit 57 receives the received access operation. The instruction operation reception unit 57 outputs the document identification information included in the access operation to the keyword extraction unit 51.

  In addition, the instruction operation reception unit 57 determines browsing destination information based on the access operation, and outputs the browsing destination information to the determination unit 81. When the access operation is an operation for instructing execution of processing for outputting the document 93 stored in the HDD 205, the output destination of the document 93 is determined as browsing destination information. Specifically, the instruction operation accepting unit 57 is configured such that the output process based on the access operation is a process of displaying a document on the display unit 206 or a process of printing out a document by any of the MFPs 100, 100A, and 100B. The user identification information of the login user is determined as browsing destination information. When the output process based on the access operation is a process of sending a document by e-mail via the network I / F 204, the instruction operation accepting unit 57 displays the user identification information of the user to whom the destination e-mail is assigned as the browsing destination Decide on information. In addition, when the output process based on the access operation is a process of transferring a document to a file via the network I / F 204, the instruction operation accepting unit 57 receives the user identification information of the user to which the storage area of the file transfer destination is assigned. Decide on browsing destination information. Further, when the output process based on the access operation is a process of displaying a document on the projector, the instruction operation accepting unit 57 accepts the user identification information of the conference participant or the department name to which the conference participant belongs. Is determined as browsing destination information.

  When the document identification information is input from the instruction operation reception unit 57, the keyword extraction unit 51 selects a document 93 specified by the document identification information input from the instruction operation reception unit 57 from among the documents 93 stored in the HDD 205. The headline part included in the read-out document 93 is extracted as a keyword. When the read document 93 includes a plurality of headlines, each of the plurality of headlines is extracted as a keyword, and the plurality of keywords are output to the keyword receiving unit 63 in order. The keyword extraction unit 51 outputs the document 93 read from the HDD 205 and the extracted keyword to the output unit 59.

  The operations of the keyword receiving unit 63, the document search unit 65, and the related user specifying unit 69 are the same as those in the document creation process. Therefore, description is not repeated here.

  The determination unit 81 receives the browsing destination information from the instruction operation reception unit 57, and receives at most M user identification information and at most N group identification information from the related user specifying unit 69. When the browsing destination information is user identification information, the determination unit 81 determines whether or not all of the user identification information input as the browsing information is included in the user identification information of the related users. If all the user identification information input as the browsing destination information is included in the user identification information of the related users, it is determined that the keyword is known to all the users of the browsing destination, but if the keyword is not included alone, it is determined to be known. do not do. Further, if the ratio of user identification information included in the user identification information of the related user among the user identification information input as the browsing destination information is equal to or greater than a predetermined value, the keyword is known to some users at the browsing destination. May be known.

  When the browsing destination information is group identification information, the determination unit 81 determines whether the group identification information input as the browsing destination information is included in the group identification information input from the related user specifying unit 69. If the group identification information input as the browsing destination information is included in the group identification information input from the related user specifying unit 69, it is determined that the keyword is known to the browsing destination group, but the keyword is input from the related user specifying unit 69. If it is not included in the group identification information, it is not determined that the information is well known. The determination unit 81 outputs a signal indicating that the keyword is known to the output unit 59 when it is determined that the keyword is known to the browsing destination, but is not known when the keyword is not known to the browsing destination. Is output to the output unit 59.

  The output unit 59 receives the document 93 and the keyword from the keyword extraction unit 51, and receives a signal indicating whether or not the keyword is known from the determination unit 81. The output unit 59 modifies the document 93 based on the signal indicating whether the keyword is known from the determination unit 81, and outputs the modified document 93 to an output destination determined based on the access operation. Specifically, when a signal indicating that a keyword is well-known is input from the determination unit 81, the output unit 59 displays a part excluding the heading from the part including the keyword in the heading and displaying the other part. Make them different. The part including the keyword in the heading is a part from the heading including the keyword to the next heading. For example, when the document 93 is composed of chapters 1 to 5, if a heading is attached to each chapter, the heading attached to each chapter is set as a keyword. , Which includes keywords.

  Specific examples of changing the display form include deleting a part excluding the heading from the part including the keyword in the headline from the document 93, or making the part including the keyword in the heading higher in brightness than the other part so as not to stand out. Or Alternatively, the display size may be reduced, surrounded by a balloon, commented out, deleted from the document 93, and displayed by a predetermined operation. The part including the keyword determined to be well-known in the headline is likely to be known to the user specified by the browsing destination information. Therefore, by making the display form different from the other parts in the document 93, A known part of the document can be skipped, and the document can be read efficiently. In particular, when deleting from the document 93, the contents of the document can be simplified and not redundant for the browsing destination user.

  When the document 93 includes a plurality of headings, the output unit 59 receives a signal indicating whether the keyword is known for each of the plurality of headings from the determination unit 81. For this reason, the output unit 59 makes each of the plurality of parts included in the document 93 display differently from the other parts based on a signal indicating whether or not the keyword is well known.

  For this reason, the user specified by the browsing destination information and serving as the output destination of the document 93 can browse the document in which the description of matters well known to the user is omitted. Further, even a single document can be displayed in different display forms if the knowledge level of the user as the output destination is different. For this reason, the document 93 can be modified to be output in accordance with the knowledge level of the viewer.

  FIG. 7 is a first flowchart illustrating an example of the flow of document creation processing. The document creation process is a process executed by the CPU 201 when the CPU 201 of the file server 200 executes a document management program stored in the ROM 202, HDD 205, or CD-ROM 209A.

  Here, a process when the user logs in to the file server 200 and creates a document will be described. In this case, the logged-in user operates the operation unit 207 and creates a document while viewing the screen displayed on the display unit 206. In addition, you may make it log in to the file server 200 by operating any of PC400-402.

  Referring to FIG. 7, CPU 201 determines whether or not a browsing user has been accepted. It is determined whether or not the user identification information of the user to be browsed has been accepted as the browsing destination information (step S01). It will be in a standby state until a browsing user is received, and if a browsing user is received, a process will be advanced to step S02. In step S02, the user identification information of the accepted browsing user is temporarily stored.

  In the next step S03, it is determined whether or not a character string is accepted. A login user receives a character string input to the operation unit 207. Next, a keyword extraction process at the time of creation is executed.

  FIG. 8 is a flowchart showing an example of the creation keyword extraction process. Referring to FIG. 8, it is determined whether or not a headline warning is set (step S21). The headline warning is preset in the file server 200 by the user. If the headline warning is set, the process proceeds to step S22; otherwise, the process proceeds to step S24.

  In step S22, it is determined whether or not the character string input by the user is a headline. If the input character string corresponds to a headline, the process proceeds to step S23; otherwise, the process proceeds to step S24. Whether or not it corresponds to a heading part may be specified as a heading when the user inputs a character string. In step S23, the heading part is set as a keyword, and the process proceeds to step S24.

  In step S24, it is determined whether or not the user has designated a character string as a keyword. If the user designates a character string as a keyword, the process proceeds to step S25. If not, the process returns to the document creation process. In step S25, the designated character string is set as a keyword, and the process returns to the document creation process.

  Returning to FIG. 7, in step S05, it is determined whether or not a keyword has been set. If the keyword is set as a result of the creation keyword extraction process in step S04, the process proceeds to step S06. If not, the process returns to step S03. In step S06, a related user search process is executed. Although details of the related user search process will be described later, this is a process of determining a user whose keyword is known as a related user. In step S07, it is determined whether or not the browsing user accepted in step S01 is the related user searched in step S06. If the viewing user is a related user, the process proceeds to step S08; otherwise, the process proceeds to step S09. In step S08, it is notified that the keyword is known, and the process returns to step S03. Specifically, a message “The reader is familiar with the items of this headline” is displayed on the display unit 206. On the other hand, in step S09, it is notified that the keyword is not known, and the process returns to step S03.

  FIG. 9 is a flowchart illustrating an example of the flow of related user search processing. The related user search process is a process executed in step S06 in FIG. Referring to FIG. 9, a document 93 stored in HDD 205 by keyword is searched (step S31). A document 93 including a keyword is extracted from the documents 93 stored in the HDD 205. Then, all of the access history information 95 corresponding to each of the at least one document 93 extracted in step S31 is extracted from the access history information 95 stored in the HDD 205 (step S32). Then, at least one document 93 extracted in step S31 is rearranged in descending order of the number of accesses (step S33). The access count is the number of access history information 95 extracted for the document in step S32.

  In the next step S34, the top L documents are selected as the selected document from the extracted at least one document 93 in descending order of the number of accesses. Here, L is a predetermined threshold value. If at least one extracted document 93 is L or less, all of the extracted at least one document 93 is selected as a selected document.

  In the next step S35, the access count for each user is calculated by counting the number of access history information for each user for all the access history information corresponding to each of L selected documents at the maximum. The number of accesses by user is the number of accesses for each user identification information. Since the access history information includes user identification information, the access history information is classified into users including the same user identification information, and the number of accesses for each user is calculated by counting the number of access history information for each user identification information.

  In the next step S36, the user identification information is rearranged in descending order of the number of accesses by user calculated in step S35. Then, the top N pieces of user identification information are selected in descending order of the number of accesses by user (step S37). Then, the user of the selected user identification information is set as the related user (step S38), and the process returns to the document creation process. A maximum of N users are set as related users.

  FIG. 10 is a second flowchart illustrating an example of the flow of document creation processing. The difference from the document creation process shown in FIG. 7 is that steps S01, S02, S06, and S07 are changed to steps S01A, S02A, S06A, and S07A, respectively. Hereinafter, differences from the procedure shown in FIG. 7 will be mainly described.

  Referring to FIG. 10, CPU 201 determines whether a viewing group has been accepted. It is determined whether or not the department name to which the browsing user belongs has been accepted as the browsing destination information (step S01A). The process waits until a viewing group is accepted. If a viewing group is accepted, the process proceeds to step S02A. In step S02A, the group identification information of the accepted viewing group is temporarily stored.

  In step S06A, a related group search process is executed. Although details of the related group search process will be described later, this is a process of searching for a group having a known keyword as a related group. In step S07A, it is determined whether or not the viewing group received in step S01A is the related group searched in step S06A. If the viewing group is a related group, the process proceeds to step S08; otherwise, the process proceeds to step S09.

  FIG. 11 is a flowchart illustrating an example of the flow of related group search processing. The related group search process is a process executed in step S06A in FIG. Referring to FIG. 11, the difference from the related user search process shown in FIG. 9 is that steps S41 and S42 are inserted between steps S35 and S36, and steps S36 to S38 are steps S36A to S36A. This is a point changed to step S38A. The other processes are the same as those shown in FIG. 9, and therefore description thereof will not be repeated here.

  In step S35, the number of accesses by user is tabulated, and in step S41, the user data 97 stored in the HDD 205 is read. Then, with reference to the read user data 97, the group identification information of the group in which the user of the user identification information is classified is specified.

  In the next step S42, the total number of accesses for each user is counted for each group, and the number of accesses for each group is calculated. User identification information having the same group identification information is classified into the same group, and the number of accesses by group is calculated.

  In the next step S36A, the group identification information is rearranged in descending order of the number of access times by group calculated in step S42. Then, the top M user identification information items are selected in descending order of the number of accesses by group (step S37A). Then, the group of the selected group identification information is set as a related group (step S38A), and the process returns to the document creation process.

  FIG. 12 is a flowchart illustrating an exemplary flow of a document browsing process. The document browsing process is a process executed by the CPU 201 when the CPU 201 included in the file server 200 executes a document management program stored in the ROM 202, HDD 205, or CD-ROM 209A.

  Referring to FIG. 12, CPU 201 determines whether a browsing operation has been accepted. If an access operation for browsing one of the documents 93 stored in the HDD 205 is received, it is determined that the browsing operation has been received. The process waits until a browsing operation is accepted (NO in step S51). If a browsing operation is accepted (YES in step S51), the process proceeds to step S52. In step S52, the operating user who performed the browsing operation is specified. Here, the user who has logged into the file server 200 is specified as the operating user.

  In the next step S 53, the document determined by the browsing operation accepted in step S 51 is read from the document 93 stored in the HDD 205. In the next step S54, a headline is extracted from the document. When the document includes a plurality of headings, all of the plurality of headings are extracted. In the next step S55, one of the headings is selected as a processing target.

  Then, the headline selected as the processing target is set as a keyword (step S56). In the next step S57, related user search processing is executed. Based on the keyword set in step S56, the related user search process shown in FIG. 9 is executed. In the next step S58, it is determined whether or not the operating user specified in step S52 is a related user. If the operating user is a related user, the process proceeds to step S59. If not, step S59 is skipped and the process proceeds to step S60.

  In step S59, the heading part including the heading selected as the processing target in step S55 is changed. The heading part starts with a heading and ends before the next heading. The display mode of the heading part is changed to be different from the display mode of other parts. Specifically, the part of the heading part excluding the heading is deleted from the document, or the brightness is increased. In step S60, it is determined whether there is a headline that has not yet been set as a processing target in step S55 among the headlines extracted in step S54.

  If there is an unprocessed heading, the process returns to step S55; otherwise, the process proceeds to step S61. In step S61, the document whose headline part has been changed is displayed on the display unit 206.

  FIG. 13 is a flowchart illustrating an exemplary flow of a document transmission process. The document transmission process is a process executed by the CPU 201 when the CPU 201 of the file server 200 executes a document management program stored in the ROM 202, HDD 205, or CD-ROM 209A.

  Referring to FIG. 13, the difference from the document browsing process shown in FIG. 12 is that steps S51, S52 and S58 are changed to steps S51A, S52A and S58A. Since other processes are the same, different processes will be described here. Referring to FIG. 13, CPU 201 determines whether a transmission operation has been accepted. If an access operation for transmitting any of the documents 93 stored in the HDD 205 by e-mail is accepted, it is determined that the transmission operation has been accepted. The process waits until a transmission operation is accepted (NO in step S51A). If a transmission operation is accepted (YES in step S51A), the process proceeds to step S52A. In step S52A, a transmission destination user is specified. Here, the user who is assigned the e-mail address set as the e-mail transmission destination by the transmission operation is specified as the transmission destination user.

  In step S58A, it is determined whether or not the transmission destination user specified as the transmission destination user in step S52A is a related user. If the destination user is a related user, the process proceeds to step S59. If not, step S59 is skipped and the process proceeds to step S60.

  Here, the document browsing process and the document transmission process are shown as an example of the document output process. However, for the process of outputting to the projector and the process of printing on the MFPs 400 to 402, the conference participants or prints are also viewed. If the user to be designated is designated as the browsing user, the document is output in such a way that the well-known name part is different from other parts, for example, deleted from the document or commented out. can do.

  For this reason, the document transmitted by the e-mail received by the transmission destination user is changed to a document whose display mode is different from that of the other part. For this reason, the transmission destination user can browse the document efficiently.

  As described above, the file server 200 according to the present embodiment sets a character string input as a headline as a keyword when executing the document creation process, and includes the keyword from the documents 93 stored in the HDD 205. If one or more documents are extracted, a user having a large number of access history information associated with the extracted one or more documents is specified as a related user, and a user designated as a viewer is included in the related user , It is determined that the keyword is known to the viewer. For this reason, since the creator is notified whether the headline is known to the viewer, it is possible to notify the information for determining whether the creator should describe in detail. For this reason, it becomes easy for the creator to create a document including information necessary for the viewer.

  Further, when executing the document browsing process, the file server 200 sets the heading of the document to be browsed as a keyword, and extracts one or more documents including the keyword from the document 93 stored in the HDD 205. If a user having a large number of access history information associated with one or more extracted documents is identified as a related user, and the document viewer is included in the related user, the portion including the heading is the document viewer. It is judged to be well known. Further, when it is determined that the part including the headline is known to the document viewer, the part including the headline determined to be known is displayed in a different form from the other parts. For this reason, a document viewer can distinguish between a well-known portion and a non-known portion at the time of browsing the document. In particular, when a known part is deleted or commented and displayed or transmitted, the known part is not displayed, so that the document can be browsed efficiently.

  Further, when executing the document transmission process, the file server 200 sets the heading of the document to be transmitted as a keyword, and extracts one or more documents including the keyword from the document 93 stored in the HDD 205. If a user having a large number of access history information associated with one or more extracted documents is identified as a related user, and the user to whom the document is to be transmitted is included in the related user, the portion including the heading It is determined that it is known to the user of the transmission destination. Further, when it is determined that the part including the headline is known to the user to whom the document is transmitted, the part including the headline determined to be known is displayed or transmitted in a different form from the other parts. For this reason, the user who receives the document can distinguish between a well-known part and an unknown part when browsing the received document. In particular, when a known part is deleted or commented and displayed or transmitted, the known part is not displayed, so that the document can be browsed efficiently. In addition, when there are a plurality of transmission destination users, the well-known portion and the unknown portion may differ depending on the plurality of users. In this case, a well-known part and a non-known part are distinguished for each of a plurality of users. Therefore, a plurality of forms of documents corresponding to a plurality of users are transmitted.

  In the above-described embodiment, the document management system 1 has been described. However, the invention can be understood as a document management method and a document management program for causing the file server 200 to execute the processes shown in FIGS. Needless to say.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
