Description

  The present invention relates to a document management technique for managing an electronic document, and more particularly to a document management technique suitable for a form when a plurality of users share an electronic document.

  In a document management system that manages shared use of an electronic document by a plurality of users, the use of the electronic document may be restricted by charging for the use of the electronic document by the user. An example of such a document management system is described in Japanese Patent Application Laid-Open No. 2001-222525.

  According to Japanese Patent Application Laid-Open No. 2004-133620, an electronic document that is frequently accessed from an external device is charged with a special fee system that is different from the regular fee for a certain period and a certain capacity even when the regular retention period has passed. Thus, a document management apparatus that permits its use is described.

  Patent Document 2 (Japanese Patent Laid-Open No. 11-157179) discloses an image processing system in which a plurality of users share one printer as an example of a technique for charging users for shared resources. In addition, it is described that a billing management apparatus that manages billing information for each user charges a usage fee to each user based on information on the total number of sheets output by each user.

  By the way, there is a limitation by the so-called lock function in the usage limitation for the electronic document. The lock function prevents editing by another user by locking the document when the user edits the document in order to prevent data inconsistency due to simultaneous update of the document.

  However, when the lock applied to the target document is released when the user finishes the work, the user continues to use the target document for a long time or remains in use (i.e., locks the target document). If the user leaves his / her seat (in the same state), another user cannot use the target document for a long time. For example, when you are away from the desk, the lock may be released due to a session timeout between the server and the client, but the target document cannot be used until the timeout period elapses. It can cause stagnation and system load. Especially when the frequency of use of a document is high, many users need to use the document, and if a document is locked for a long time by a specific user, the entire business may be disturbed. There is also sex.

  In this regard, the charging methods described in Patent Document 1 and Patent Document 2 limit the use of the document by charging according to the storage period of the target document, the total number of output users, and the like. However, no consideration is given to the problem of the lock function as described above.

Note that “Usage upper limit / time” 208 stores the upper limit usage amount per time (eg, 15000 yen) of the document. In the state 209, information indicating the current locked state of the document (for example, locked or not locked) is stored.

  The billing management unit 103 in FIG. 1 has a billing management function for managing billing for the use of a document by a user, and stores billing management information related to billing of the document in the billing management information storage unit 104. The billing fee is calculated for each document and includes a basic fee and an additional fee. The charge management unit 103 has a basic fee determining function for determining a predetermined basic fee for use of a document by a user, and an additional fee determining function for determining a predetermined additional fee. Details of the billing fee (basic fee, additional fee) will be described later.

  FIG. 3 is a diagram illustrating an example of a data configuration of a charging management table stored in the charging management information storage unit 104. As shown in the figure, the billing management table includes “document ID” 301, “number of users” 302, “use time” 303, “no operation penalty (first addition fee)” 304, “locked use request addition” Data items such as “charge (second charge)” 305 and “charge fee (basic charge)” 306. The “number of users” 302 stores the number of users of the document in the past predetermined period (here, a unique number is used instead of the number described as an example). “Use time” 303 stores the total use time of the document in the past predetermined period. FIG. 10 is a diagram for explaining the “number of users” 302 and “usage time” 303. According to the figure, the “number of users” 302 stores four persons, and the “use time” 303 stores the total of t1 to t7.

  The “no-operation penalty” 304 is imposed on the user who is in use when the user who is using the document does not perform an operation while using the document (that is, when the document is locked) exceeds a predetermined threshold. To be added (first addition fee) or information for calculating the addition fee is stored. The content of the first additional fee, that is, the penalty fee (addition rule) can be set as appropriate according to the design. For example, it is an additional fee per unit time, and when the no-operation time exceeds a predetermined threshold time This is imposed on the duration from the (penalty start time) to the time when the next operation is detected (penalty end time).

  The “in-lock use request addition fee” 305 is imposed on the user, which is generated when the user receives a document use request from another user for the document being used (that is, the locked document). An additional fee (second additional fee) or information for calculating the additional fee is stored. The content of the second additional fee, that is, the usage request additional fee during locking (addition rule) can be set as appropriate according to the design. For example, it is added at the time of accepting a document usage request from another user, In addition, the value can be set so as to increase according to the number of document use requests from other users.

  “Billing fee” 306 stores a basic fee charged to the user for use of the document or information for calculating the basic fee. The basic fee is a document usage fee per unit time, and is determined according to the document usage status. The parameter indicating the usage status of the document can be appropriately set according to the design. For example, the frequency of use of the document management apparatus for each time period specified from the number of users, the usage time, the number of users, and the usage time. The parameters such as

  Here, FIG. 4 is a diagram showing an example of the data structure of the usage frequency table for each time zone of the document management apparatus stored in the charging management information storage unit 104. As shown in the figure, the usage frequency table for each time zone has data items such as “time zone” 401 and “ratio” 402. In the “time zone” 401, for example, a plurality of time zones obtained by dividing one day by a predetermined time unit are stored. The “ratio” 402 stores, for example, a ratio of the number of usage hours in the time period to the total number of usage hours of the document management apparatus 100 in a past predetermined period.

  FIG. 9 is a diagram for explaining an example in which the usage frequency is different for each time zone. In the figure, for example, the usage frequency of the document management device increases at 9 o'clock immediately after the start time, around 13:30 immediately after the lunch time, and around 17:00 just before the end time, while at 7 o'clock before the start of work, during the lunch time It is low at 12:00, around 20:00 after the closing time, and it is shown that the frequency of use varies depending on the time zone.

  Returning to FIG. 1, the user management unit 105 includes a user management function for managing user information of a user who uses a document, and stores the user information in the user information storage unit 106. Specifically, when a login request from a user is accepted, an authentication function for authenticating the user is provided. If the authentication is successful, a session is established with the client terminal of the user, and user information is stored for each session. Manage.

  FIG. 5 is a diagram illustrating a data structure of user information (user information table) stored in the user information storage unit 106. As shown in the figure, the user information table includes “user ID” 501, “name” 502, “login password” 503, “affiliation” 504, “use fee” 505, and “remaining use fee”. ”And the like. The “use fee” 505 stores the total of the use fees that the user has already used among the predetermined use fees that are periodically given to the user from the document management apparatus 100. The “remaining usage fee” 506 stores a usage fee that has not been used yet, that is, a usage fee that can be used in the future.

  The document main body storage unit 107 in FIG. 1 is a storage device that stores information on a document main body to be used by the user, and has a function as a database, for example. The document only needs to be usable by the user at the client terminal 120, and the content thereof is not particularly limited, but data such as text, a still image, a moving image, a video, and a sound is applicable.

  The access log 108 is a storage device that stores a past use history (access log) of a document by a user, and has a function as a database, for example. The access log is referred to when calculating the usage frequency of the document management apparatus 100 for each time zone, or when calculating a document charge.

  FIG. 6 is a diagram illustrating the data structure of the access log. As shown in the figure, the access log has data items such as “start / end” 601, “user ID” 602, and “operation” 603. The “start / end” 601 stores the use start time and use end time of the document. The “operation” 603 stores information indicating the usage contents for the document.

  The communication unit 109 in FIG. 1 is configured to communicate with the client terminal 120 and the like via the network 140 and to input and output information. For example, an existing communication module such as a network interface card (NIC) or a TCP / IP driver is provided.

  Next, the client terminal 120 will be described. In FIG. 1, two client terminals (120, 130) are illustrated, but the client terminal 130 has the same configuration as the client terminal 120, and thus description thereof is omitted here.

  The client terminal 120 includes a document application 121, a process management unit 122, client software 123, an input / output device 124, and a communication unit 125.

  The client terminal 120 includes a CPU as a control unit that controls processing and operation of the client terminal 120, a memory such as a ROM and a RAM, an external storage device (HDD) that stores various information, a communication interface, an input interface, a display, and the like. It is possible to apply a general-purpose computer equipped with the output interface and hardware such as a bus connecting them. The client terminal 120 can function as, for example, the process management unit 122 described above, when the CPU executes a predetermined program stored in a memory or an external storage device.

  The document application 121 is application software that provides a predetermined function to the user by being stored in an external storage device or the like and executed by the CPU. For example, existing software such as an editor having a document editing function can be applied.

  The process management unit 122 has a function of managing the use of a document by a user using a document application. Specifically, it manages the start and end of use of a document by a user and calculates a basic charge for calculating the basic charge for the use of a document by the user. An additional charge calculation function for calculating the additional charge when it satisfies, a termination function for forcibly terminating the user's document use when the total amount of the basic charge and the additional charge satisfies a predetermined termination condition, Is provided.

  The predetermined addition condition can be set as appropriate according to the design. Here, as an example, whether or not the no-operation time exceeds a predetermined threshold during document locking (first addition condition), or Whether or not a use request from another user for the document is accepted while the document is locked (second addition condition) is set. The predetermined termination condition includes, for example, whether or not the total amount has reached the usage upper limit (first termination condition), and whether or not the total amount has exceeded the user's remaining usage fee (second termination condition). Is set.

  The client software 123 is application software that is stored in an external storage device or the like and is executed by the CPU to provide a user with a function of using the document management apparatus 100. For example, existing software such as a browser having an information browsing function can be applied.

  The input / output device 124 is an input device such as a keyboard and a mouse for a user to input various instructions, and an output device such as a display and a printer that outputs various information.

  The communication unit 125 is configured to communicate with the document management apparatus 100 and the like via the network 140 and to input and output information. For example, an existing communication module such as a network interface card (NIC) or a TCP / IP driver is provided.

  The network 140 is a line for transmitting and receiving information between the document management apparatus 100 and the client terminals (120, 130). The network 140 may be, for example, the Internet, a dedicated line, a packet communication network, a telephone line, a LAN, a corporate network, other communication lines, a combination thereof, or the like. It doesn't matter.

  Next, a flow of document management processing according to the present embodiment will be described with reference to FIGS.

  It should be noted that the processing steps shown in the flowcharts shown in FIGS. 7 and 8 can be executed in any order or in parallel as long as the processing contents do not contradict each other. Moreover, you may add another step between each process step. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step. In the following processing, a case where the user edits a document will be described as an example.

  As a premise, first, the client terminal 120 accesses the document management apparatus 100 using the client software 123 and acquires a document list. When the user selects a desired document from the document list, the editing request for the selected document is transmitted to the document management apparatus 100 (S1).

  When the document management unit 101 of the document management apparatus 100 receives the document editing request, the document management unit 101 checks the lock state of the target document by referring to the document management table (S2).

  If the target document is locked (YES in S2), an uneditable message is transmitted to the client terminal 120 (S3). In addition, the client terminal of the user who has locked the target document is notified that there has been an edit request for the target document (S4).

  On the other hand, when the target document is not locked (NO in S2), the target document is locked and the fact that it is locked is stored in the document management table (S5). Then, the charging management unit 103 is requested for charging information of the target document (S6).

  Upon receiving the charge information request, the charge management unit 103 requests the access log 108 for the access log of the target document (S7). The access log 108 transmits the access log of the target document to the charge management unit 103 (S8).

  The charge management unit 103 refers to the usage frequency table for each time zone and updates the contents of the usage frequency table for each time zone based on the access log (S9). Further, referring to the charge management table, the “number of users” 302 and “use time” 303 of the charge management table are updated based on the access log (S10).

  Based on the contents of the updated charging management table and the usage frequency table for each time zone, the basic charging fee per unit time for the use of the target document is calculated. Specifically, a parameter value for determining the basic billing fee is calculated. Here, a user parameter based on the number of users, a usage time parameter based on usage time, and a time zone parameter based on time zone usage frequency are set as parameters. Note that the basic billing fee can be calculated using one of these three parameters or any combination, and other parameters may be added according to the specifications and design.

  For example, the value of the user parameter is determined so that the basic charging fee increases as the number of users increases. The usage time parameter is set such that, for example, a document with a longer usage time has a higher basic billing fee. For the time zone parameter, for example, a value is set such that the basic billing fee increases in a time zone where the usage frequency is high. It should be noted that the user parameter and the usage time parameter do not change in the parameter value during use of the document, while the time zone parameter changes in the parameter value according to the usage time zone.

  The charging management unit 103 dynamically calculates a basic charging fee for each time zone based on the determined parameters. Note that the penalty fee for the no-operation penalty and the editing request addition fee during locking can be calculated in the same manner.

  The billing management unit 103 documents information on the basic billing fee for each time zone of the target document, information on the penalty fee, information on the editing request addition fee during locking, and information for billing calculation including the upper limit of document usage per time The data is transmitted to the management unit 101 (S12).

  The document management unit 101 transmits a user information acquisition request of the target user to the user management unit 105 (S12). The user management unit 105 acquires user information of the target user from the user information table and transmits it to the document management unit 101 (S13). The user information includes at least the user's remaining usage fee.

  The document management unit 101 acquires the body data of the target document from the document body storage unit 107 (S14).

  The document management unit 101 transmits the main data, billing calculation information, and user information of the target document to the client terminal 120 (S15).

  Next, as shown in FIG. 8, the client terminal 120 starts a document application management process (S16).

  The process management unit 122 stores the billing calculation information and user information of the target document in a predetermined storage area (S17).

  The client terminal 120 activates the document application 121 (S18). Then, the process management unit 122 transmits a target document editing start notification to the document management unit 101 of the document management apparatus 100 (S19).

  Upon receiving the editing start notification from the client terminal 120, the document management unit 101 of the document management apparatus 100 requests the access log 108 to update the access log (S20). The access log 108 indicates the start time, user ID, and operation status. The access log is updated by writing (S21).

  On the other hand, the process management unit 122 of the client terminal 120 executes termination monitoring processing for monitoring whether or not the document application is terminated by the user while the document application is activated (S22).

  In addition, the process management unit 122 executes a no-operation monitoring process for monitoring whether or not the user is no-operation (S23). Specifically, the no-operation time during which no editing instruction or the like is input via the input / output device 124 is measured, and it is determined whether or not the measured no-operation time has exceeded a predetermined threshold time. If the determination result is right (YES), a no-operation penalty is generated. The no-operation penalty will be described later.

  The process management unit 122 executes a basic charging fee calculation process for calculating a basic charging fee for the user's document usage (S24). The basic charging fee is calculated based on the basic charging fee per unit time for each time zone included in the charging calculation information of the target document and the usage time of the user.

  When a no-operation penalty occurs, an additional fee is calculated based on the penalty fee included in the charging calculation information of the target document, and this is added to the basic charging fee. Specifically, the process management unit 122 determines a penalty fee (based on the elapsed time from the time when the no-operation time exceeds a predetermined threshold time until the next operation is detected and the penalty fee per unit time ( (Addition fee) is calculated. The penalty fee increases as the time of no operation increases. When the input / output device 124 accepts a user operation, the no-operation time measured up to that time returns to the initial value, and the addition of the penalty fee is stopped.

  Further, when an editing request from another user is generated, an additional fee is calculated based on the locked editing request additional fee included in the charging calculation information of the target document, and this is added to the basic charging fee. Specifically, when it is notified from the document management unit 101 that there has been an editing request from another user (S24-1: YES), the process management unit 122 adds an in-lock editing request addition fee according to the number of notifications. Calculate and add to the basic charge.

  The process management unit 122 determines whether or not the total charging fee of the basic charging fee, the penalty fee, and the locked editing request addition fee satisfies a predetermined forced termination condition (S25). Specifically, it is determined whether or not the total charging fee exceeds the remaining usage fee of the user, or whether or not the total charging fee exceeds the upper limit of usage per time of the target document. If the remaining usage fee or usage upper limit is exceeded (YES), forced termination processing is executed.

  When the process management unit 122 forcibly terminates the document application, the process management unit 122 presents a forced termination message as illustrated in FIG. 12 to the user. Note that in the forced termination message, a message for confirming to the user whether or not to transmit the edited target document to the document management apparatus 100 (whether or not to update) may be displayed.

  After displaying the above message, the process management unit 122 forcibly terminates the document application. When the user selects update, the process management unit 122 notifies the editing end notification together with the updated document data and the document of the document management apparatus 100. The data is transmitted to the management unit 101 (S27).

  When the document management unit 101 receives the edit end notification from the client terminal 120, the document management unit 101 transmits an access log update request to the access log 108 (S28), and the access log 108 updates the access log by writing the end time (S28). S29).

  In addition, the document management unit 101 transmits a user information update request to the user management unit 105 (S30), and the user management unit 105 updates the user usage fee and the remaining usage fee based on the total charging fee of the user (S30). S31).

  Further, when the updated document data is transmitted, the document management unit 101 updates the existing document data in the document main body storage unit 107 with the updated document data, and the document attributes (updater ID, update date / time, etc.) of the document management table. Is updated (S32).

  Then, the document management unit 101 unlocks the target document and updates the state of the document management table to “unlocked state” (S33). As a result, the document can be used by other users.

  FIG. 11 is a diagram showing the relationship between the elapsed time of document use and the total charge amount of the user. This figure shows a state in which an in-lock editing request addition fee is added when a usage request is made by another user, and a state in which a penalty fee is added due to the occurrence of a no-operation penalty.

  As described above, according to the present embodiment, when the usage status for a document satisfies a predetermined additional condition during document locking, the predetermined additional fee is charged for the basic fee. As a result of the time exceeding the user's remaining usage fee or the usage upper limit being advanced, the forced termination time of the document can be further advanced. This makes it possible to prevent a specific user from locking and occupying a particularly frequently used document for a long time.

  In addition, for example, when an editing request from another user is accepted while the document is locked, an additional fee is charged according to the number of times the document is received, so the more editing requests from other users, the higher the additional fee. The forced termination time of the document can be further advanced. This makes it possible to efficiently use the document according to the usage status of the document.

  Also, for example, if a no-operation penalty occurs during document locking, a penalty fee is added until the next operation is detected, so the longer the no-operation time becomes, the longer the penalty fee becomes, The forced termination time of the document can be further advanced. In addition, since the user concentrates on the document editing work so as to avoid the penalty fee, the efficiency of the document editing work of each user can be promoted.

  Also, according to the present embodiment, the basic charge is set according to the frequency of use of the document. Therefore, the basic charge is high when the frequency of use of the document is high, and the basic charge is set when the frequency of use of the document is low. Fees are also lower. Therefore, it is possible to avoid restricting the use of the document unnecessarily.

[Modification of the above embodiment]
The present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. For this reason, the said embodiment is only a mere illustration in all points, and is not interpreted limitedly.

  (1) For example, the no-operation penalty addition rule is not limited to the above-described content. For example, after the penalty start time, every predetermined time (for example, every 10 minutes), the rule increases. You may set so that the amount set to may be added.

  (2) In addition, the rule for adding the usage request addition fee during locking is not limited to the above-described content, for example, an addition fee per unit time, and the elapsed time since the reception of a document usage request from another user Depending on, it may be set to calculate the additional fee.

  (3) For example, the process management unit 122 determines whether or not the no-operation time exceeds a predetermined end time threshold, and if it is determined that the no-operation time exceeds the end time threshold, forcibly at that time You may make it complete | finish a process. According to this, even when the user's total billing fee does not exceed the user's remaining usage fee or usage upper limit, the document is forcibly terminated, so that the document can be unlocked more quickly.

  (4) For example, the process management unit 122 determines whether or not the number of notifications of other users 'edit requests exceeds a predetermined end count threshold, and the number of other users' edit request notifications exceeds a predetermined end count threshold. If it is determined that the process has been completed, the process may be forcibly terminated at that time. According to this, even if the user's total billing fee does not exceed the user's remaining usage fee or the upper limit of usage, the document is forcibly terminated, so the document is forcibly terminated. It becomes possible to accelerate.

  (5) It may be determined whether to charge for each document. For example, a document with a low update frequency or a personally owned document may not be charged.

  (6) The document management system of the present invention can be applied to, for example, a book lending system as an example of a system for sharing resources among a plurality of users. During the library rental period, any book can be lent for a certain period. However, because popular books have loan requests from many people, it may be desirable to shorten the loan period of such highly requested books so that as many people as possible can use them. is there. On the other hand, it may be more convenient for the user to give a loan period that is longer than the normal loan period for books that are not so lent (for example, technical books). By applying the resource management system of the present invention to such a book lending system, the lending period of the book can be dynamically set according to the frequency of use of the book (number of users, time of use).
