Description

  The present invention relates to a document management system, a document management method, a document management server, and a client terminal, and in particular, a document management system, a document management method, and a document management for managing a document displayed on a client terminal with a document management server via a network. The present invention relates to a server and a client terminal.

  When a user displays a document on a client terminal such as a notebook PC (Personal Computer), the document is widely used by providing the latest version of the document from a context server (document management server) that manages the document. Document attribute management systems have been proposed (for example, see Patent Document 1).

  Such a system is desired to be widely used regardless of inside or outside of an intranet. For example, a user is not limited to a specific environment such as HTTP (HyperText Transfer Protocol) from a client terminal and is relatively easy. By making it possible to access the document management server using a protocol, the system can be used more effectively.

  On the other hand, a document (context) to be provided to a user may be required to be different depending not only on the time (version) but also on the location (position) of the user such as inside or outside the company (inside or outside of the intranet).

  For example, considering the case of using the system from outside the intranet, a client terminal in which a document is already stored by a user outside the company or an employee (in-house user) such as PSTN (Public Switched Telephone Networks) This may be the case when accessing the server from a low-speed line.

  In order to utilize the document at more opportunities, it is necessary to notify the user of trivial or uncertain information, but such provision of information is unnecessary for external users, For users using low-speed lines, communication may be hindered.

  In addition, for example, specifications such as specifications are updated frequently in the company, and it is preferable for many users to see them. Notifying the specification document is useless information.

  Furthermore, as an inquiry destination regarding document information, it may be appropriate to switch the information itself, for example, an internal number is notified to users in the company and an external number is notified to users outside the company.

  For example, when an employee (in-house user) who interferes with communication with a user who uses a low-speed line puts a document in a notebook PC and accesses the server using PSTN, the user communication is performed. As one of the methods for preventing the communication from being interrupted, when accessed via the PSTN, it is possible to switch to only the summary of important communication items related to the document, notify the destination first, and terminate the communication once. There is a way to avoid sudden start of long-term communication.

For example, as a method for preventing the communication of a user using a low-speed line from being interrupted, an employee takes a notebook PC (client terminal) storing documents outside the company and accesses the server via the PSTN. In this case, instead of providing the latest version of the document itself, it is possible to switch to only the summary of important communication items related to the document and notify the destination first, to avoid suddenly starting a long communication over a low-speed line. .
Japanese Patent Laid-Open No. 2004-110682

  However, such switching of information (document) can be realized by a method in which the user himself / herself switches the document by providing a client terminal with a manual information switching means. However, in a system dependent on a document, Since each document is connected to a different server, information switching must be set for each document, which complicates the user.

  Also, if the server is temporarily accessed from a low speed line from outside the company, it is much more convenient to switch automatically to in-house notification at the same time as returning to the office than to manually setting.

  Therefore, in the present invention, a document management system, a document management method, and a document that can automatically provide an appropriate document to the user according to a location (position) where the user manages the document managed by the server.

  Hereinafter, a document management system according to the present invention will be described in detail using embodiments.

  FIG. 1 is a schematic conceptual diagram showing an example of a configuration of a document management system according to the present embodiment. FIG. 1A shows a case where both the document management server 10 and the client terminal 20 are in the intranet 30 (in-house). FIG. 6B is a diagram showing an example of the configuration when the client terminal 20 is outside the intranet 30 (outside the company).

  As shown in the figure, the document management system includes a document management server 10 and a client terminal 20, and when both the document management server 10 and the client terminal 20 are in the intranet 30, FIG. As shown in FIG. 5B, when the document management server 10 and the client terminal 20 are connected via an intranet network 40 such as a LAN (Local Area Network) and the client terminal 20 is outside the intranet 30. The document management server 10 and the client terminal 20 are connected to each other via a gateway 60 that connects the intranet network 50 such as PSTN, the intranet network 40, and the networks (40, 50) inside and outside the intranet.

  The document management server 10 is a server that manages documents, and includes a document database 11, a position determination unit 12, a document management unit 13, and a control unit 14, as shown in FIG. Is done.

  The document database 11 is a storage device such as an HDD (Hard Disk Drive) and stores a document (context) to be displayed on the client terminal. Specifically, for example, an intranet document for the intranet with the newest information, an external board document for the intranet that excludes confidential matters and uncertain elements that are not preferably disclosed outside the company, and a PSTN A plurality of types of documents having different contents are stored for each document, such as a simplified version document with a reduced amount of information for communication.

  The position determination unit 12 determines the position of the client terminal. Specifically, for example, as shown in FIG. 1A, when accessed from the intranet network 40 without going through the gateway 60, it is determined that there is a client terminal in the intranet 30, and FIG. As shown in FIG. 5, when accessed from the client terminal 20 via the gateway 60, it is determined that the client terminal 20 is outside the intranet 30. Note that the position of the client terminal (inside or outside the intranet 40) may be determined based on the access route to the IP address of the client terminal. At this time, the type of network 50 outside the intranet (VPN (Virtual Private Network), PSTN, etc.) may be determined to determine whether a low-speed line is used.

  The document management unit 13 switches (determines) a document to be displayed on the client terminal 20 according to the position of the client terminal 20. Specifically, for example, as shown in FIG. 1 (a), if there is a client terminal in the intranet 30, the document to be displayed on the client terminal is determined as an in-house version document, as shown in FIG. 1 (b). If the client terminal 20 is located outside the intranet 30, the document to be displayed on the client terminal is determined to be an external document. If the client terminal uses a low-speed line such as PSTN as the network 50 outside the intranet, the document to be displayed on the client terminal may be determined as a simplified document.

  The control unit 14 performs processing for controlling the entire document management server 10 and transmits / receives information such as documents to / from the client terminal.

  The position determination unit 12 and the document management unit 13 are realized by software installed on the document management server. The document management server is a computer that can operate as a server, and each function shown in FIG. This is realized by executing a program that realizes the section.

  Using the above configuration, when the document management server 10 receives a document display request from a client terminal, the position determination unit 12 determines the position of the client terminal, and the document displayed on the client terminal is determined according to the position of the client terminal. This is determined by the document management unit 13. Then, the determined document is extracted from the document database 11 and transmitted to the client terminal.

  The client terminal 20 is an information processing apparatus such as a notebook PC (Personal Computer), and includes an operation / display unit 21 and a control unit 22 as shown in FIG.

  The operation / display unit 21 includes an operation device such as a keyboard and a mouse and a display device such as a display. The operation / display unit 21 receives an operation from the user and displays information and a document provided to the user.

  The control unit 22 performs processing for controlling the entire client terminal 20 and transmits / receives information such as documents to / from the document management server.

  Using the above configuration, when the client terminal 20 receives a document display request, for example, when the user inputs a document name using the operation / display unit 21, the client terminal 20 transmits the display request to the document management server and receives the document request from the document management server. The document is displayed on the operation / display unit 21.

  FIG. 4 is a flowchart illustrating an example of a process flow of the document management system according to the present embodiment.

  First, when a document display request is received from a user at a client terminal (step 100), the display request is transmitted to a document management server that manages the document (step 101).

  The document management server determines the position of the client terminal (step 102), and determines the type of document to be displayed on the client terminal based on the determination result (step 103).

  Then, the document management server transmits the determined document to the client terminal (step 104), and the client terminal displays the received document (step 105).

  As described above, in the present invention, in order to determine (switch) the document to be provided to the user based on the position of the client terminal, for example, “a public version specification document is provided to an external (outside the intranet) user and a new specification is provided. Provide a draft version of the certificate to internal (intranet) users. “Provide price lists to external users and provide partition price changes to internal users.” Can provide different documents to the user.

  By the way, the position of the client terminal can be determined on the client terminal side by using a function such as an OS (Operating System) or a browser installed in the client terminal. Will be described in detail.

  FIG. 5 is a functional block diagram illustrating an example of the configuration of the client terminal according to the present embodiment.

  As shown in the figure, the client terminal 20 includes an operation / display unit 21, a control unit 22, and a position determination unit 23.

  The position determination unit 23 determines the position of the client terminal (own terminal). Specifically, for example, as shown in FIG. 1A, when accessing the document management server from the intranet network 40, it is determined that the own terminal 20 is in the intranet 30, and FIG. As shown, when accessing the document management server from the network 50 outside the intranet via the gateway 60, it is determined that the own terminal 20 exists outside the intranet 30.

  The position determination unit 23 is realized by software installed in the client terminal.

  Using the above configuration, the client terminal 20 determines the position of its own terminal when receiving a document display request, for example, when the user inputs a document name on the operation / display unit 21, and determines the display request and its own terminal position. The result is transmitted to the document management server, and the document received from the document management server is displayed on the operation / display unit 21.

  As shown in FIG. 2, the document management server 10 in this embodiment includes a document database 11, a position determination unit 12, a document management unit 13, and a control unit 14.

  Using the above configuration, when the document management server 10 receives the document display request and the position determination result from the client terminal, the position determination unit 12 determines the position of the client terminal based on the position determination result at the client terminal, The document management unit 13 determines a document to be displayed on the client terminal according to the position of the client terminal. Then, the determined document is extracted from the document database 11 and transmitted to the client terminal.

  FIG. 6 is a flowchart illustrating an example of a processing flow of the document management system according to the present embodiment.

  First, when a document display request is received from the user at the client terminal (step 200), the position of the own terminal is determined (step 201), and the position determination result of the own terminal and the display request are sent to the document management server that manages the document. Transmit (step 202).

  The document management server determines the position of the client terminal based on the position determination result received from the client terminal (step 203), and determines the document to be displayed on the client terminal based on the determination result (step 204).

  Then, the document management server transmits the determined document to the client terminal (step 205), and the client terminal displays the received document (step 206).

  As described above, in this embodiment, the position of the client terminal is determined by the client terminal, and the document to be displayed on the client terminal can be determined and switched based on the determination result.

  By the way, there is a case where the in-house version document is desired to be displayed on the client terminal outside the intranet, for example, when the in-house version document is stored in the client terminal and temporarily taken out of the intranet.

  However, it is not desirable to display an in-house version of a document containing information that is not desirable to be disclosed outside the company, such as confidential matters, outside the intranet.

  Therefore, a document management system capable of determining a document to be displayed on the client terminal based on the position of the client terminal and the usage status of the document will be described in detail below using an embodiment.

  FIG. 7 is a functional block diagram illustrating an example of the configuration of the client terminal according to the present embodiment.

  As shown in the figure, the client terminal 20 includes an operation / display unit 21, a control unit 22, a document storage unit 24, and a usage status management unit 25.

  Note that the same reference numerals as those used in FIG. 3 are attached to portions that perform the same functions as those in FIG. 3, and detailed descriptions thereof are omitted.

  The document storage unit 24 is a storage device such as an HDD, and stores a document to be displayed on the client terminal 20.

  The usage status management unit 25 manages the usage status of the document. Specifically, for example, the number of times the document was displayed outside the intranet within a certain period (one day or the period from going out to the office, etc.), or after taking the document out of the intranet and displaying it It manages arbitrary information that can grasp the usage status of a document, such as a period of time that has passed without displaying the document in the intranet.

  The usage status management unit 25 is realized by software installed in the client terminal.

  When the client terminal 20 stores the document in the document storage unit 24 using the above configuration and receives a display request by the user inputting the document name of the document on the operation / display unit 21, the usage status of the document is Is extracted from the usage status management unit 25, and the display request and usage status are transmitted to the document management server.

  When the document display permission is received from the document management server, the document stored in the document storage unit 24 is displayed on the operation / display unit 21. When the document is received from the document management server, the received document is operated / displayed. Displayed in the unit 21.

  As shown in FIG. 2, the document management server 10 in this embodiment includes a document database 11, a position determination unit 12, a document management unit 13, and a control unit 14.

  Here, the document management unit 13 determines a document to be displayed on the client terminal 20 according to the position of the client terminal 20 and the usage status of the document. Specifically, for example, when the usage status satisfies a predetermined condition even when the client terminal is inside or outside the intranet, display of the in-house version document stored in the client terminal is permitted, and the client terminal If it is outside the intranet and the usage status does not meet the prescribed conditions, it is determined as an external document.

  Here, as the predetermined condition, for example, an arbitrary condition such as the number of times the document is displayed or a period of time elapsed since the document is displayed can be used, and the number of times the document is displayed outside the intranet It is determined that the predetermined condition is satisfied, for example, if it does not exceed the predetermined period, or if the period after the document has been released outside the intranet does not exceed the predetermined period.

  Note that the document database 11, the position determination unit 12, and the control unit 14 perform the same functions as those of the document management server described in the first embodiment with reference to FIG. 2, and detailed descriptions thereof are omitted.

  Using the above configuration, when the document management server 10 receives a document display request and the usage status of the document from the client terminal, the position determination unit 12 determines the position of the client terminal, and the position of the client terminal and the document The document management unit 13 determines a document to be displayed on the client terminal based on the usage status of the document, and when the determined document is stored in the client terminal, display permission is transmitted to the client terminal, and the determined document is the client terminal. If not stored, the document is extracted from the document database 11 and transmitted to the client terminal.

  FIG. 8 is a flowchart illustrating an example of a processing flow of the document management system according to the present embodiment.

  First, a document is stored in a client terminal (step 300), a display request for the document is received from a user (step 301), a usage status of the document is extracted (step 302), and a document management server that manages the document The display request and usage status are transmitted to (step 303).

  The document management server determines the position of the client terminal (step 304), and determines whether or not to display the document stored in the client terminal based on the determination result and the usage status (step 305).

  If it is determined that the document stored in the client terminal is to be displayed (YES in step 305), the display permission of the document is transmitted to the client terminal (step 306), and the client terminal displays the stored document. It is displayed (step 307).

  On the other hand, if it is determined not to display the document stored in the client terminal (NO in step 305), the document to be displayed on the client terminal is determined (step 308), and the determined document is transmitted to the client terminal (step 309). ) The client terminal displays the received document (step 307).

  In this embodiment, according to the document stored in the client terminal, the display permission of the document or the document to be displayed on the client terminal is transmitted to the client terminal. However, the document is stored in the client terminal. The document may be transmitted from the document management server to the client terminal regardless of whether or not there is.

  Even when a document stored in the client terminal is displayed, if there is an updated version of the document (type), the document may be transmitted from the document management server to the client terminal and displayed. .

  Further, the document to be displayed on the client terminal is determined on the client terminal, and if the determined document is different from the document stored on the client terminal, the document management server may be accessed to obtain the document. Good.

  In addition, it is preferable that the usage status of the document is copied together with the document when the document is copied to another client terminal or the like. Documents copied outside the company will take over the usage status of the original that was the source of the copy.For example, if a certain period of time has passed since the original, which is an internal document, was taken outside the company, As with the original, the copied document can be switched, such as switching to a document for use.

  As described above, in this embodiment, even if an intranet document is stored in the client terminal, the document is managed according to the user situation, such as switching to an external document when the access count exceeds the limit value. be able to.

  In addition, if the user has taken the document out of the office temporarily, the user can view the document in the same way as in the company, and the number of accesses is limited even if the document is taken out by e-mail etc. When knowledge is exceeded, the document is switched to an external document, so that the user can receive a document according to the situation without being particularly conscious.

  As described above, according to the present invention, even when a plurality of documents managed by different document management servers are used by one client terminal, the positions of the server and the client can be determined without the user being aware of the document settings. The document can be switched according to the situation.

  In addition, because documents can be switched according to the location of the client terminal, etc., it is possible to switch between items inside and outside the company, limit notification of useless information, and optimize use on low-speed lines by adjusting the amount of communication. It becomes possible.

  In addition, since the document displayed on the client terminal can be switched according to the usage status, the document temporarily taken out of the company is the same as in the intranet for a certain period of time without the user changing the settings. Can be displayed on the client terminal.
