First, both folders and drawers in Xerox Star are technologies for storing electronic documents. The difference between the two is that the folder is for storing documents on the user's workstation, while the drawer is for storing documents on a file server on the network. In these techniques, a version number is automatically given by sequentially saving documents having the same name, and the progress of editing a certain document can be saved in order.

Share in Xerox Star
In addition to the drawer function described above, dBook has a lock mechanism that prevents multiple users from editing the same document at the same time, and a function that allows the user to write the reason for changing each version.

Next, SCC in the UNIX development environment
Version management technologies such as S and RCS are for managing source codes in various languages. Versions can be stored hierarchically to manage many versions involved in programming development. It is also possible to leave a comment for each version. In addition, this technology also shows how many lines were added and deleted compared to the previous version.

In general hypertext technology such as NoteCards, information can be described as nodes and the information can be linked by links. In addition, Note
In some systems such as Cards, various types of links can be prepared and selected by the user, or a new type of link can be defined.

[0008] TextLink has a link description language and can automatically form a link to a node satisfying a specific condition. On the other hand, FISH is a system for sharing know-how within the group. F
In ISH, based on the keyword entered by the user,
The links between each know-how are automatically formed at regular intervals.

[0009]

[Problems to be Solved by the Invention] Drawer and Share
With traditional file management techniques such as dBook,
It is mainly the date, owner, version number, etc. that are automatically provided, and it is necessary for the user to describe the relationship between the document before editing and the document after editing.
In SCCS and RCS, the number of added lines and the number of deleted lines are presented, but it is still necessary for the user to perform all the work of determining the intention of the change by editing and describing it.
TextLink that automatically adds links between nodes
The FISH and FISH add links based on database search expressions and keywords, and cannot add links by determining the intention of modification by editing.

In view of the above, the main object of the present invention is to accurately determine the intent of change for each user when a change is made to a document group jointly edited by a plurality of users. . It is also an issue to present the change intention to each user in an easy-to-understand form.

Further, the present invention (Claim 11) has a function of rewriting the contents of the change intention judging rule stored in the change intention judging rule storing means based on the user's action.

[0019]

The desired document information is sent from the document management section 3 to the document editing section 1 in response to a user's editing start request.
The document editing unit 1 edits a document in response to a user's editing request for document information. At that time, the user name is input by the editing user name input means 1c.

The edited document information is stored in the document management unit 3
Stored in. In one aspect (Claim 1) of the present invention, the change intention judging means 3b judges the change intention from the information related to the change of the content of the document by the change intention judging rule stored in the change intention judging rule storing means 3d.
As the information relating to the change of the content of the document, for example, the difference information between the document before editing and the document after editing and the record information of the editing action performed by the editing user at the time of editing can be used. At this time, as the change intention determination rule, the change intention determination rule corresponding to the user name input by the editing user name input means 1c is selected and used. The determined change intention is
It is saved in the document management unit 1 (document change history saving means 1h).

The editing action performed by the user is recorded by the editing action storage means 2e. Although all editing actions may be recorded, in one aspect (claim 2) of the present invention, only the editing actions necessary for the rule applied to each user are selected and saved.

By the above processing, the device can precisely estimate the change intention at the time of editing by using the change intention determination rule suitable for each user, and save it as the change history information.

When the user designates a document for which the change history is to be displayed, the change history display unit 2 retrieves the document information and the document change history information from the document management unit 3, and displays the change history of the document together with the change intention. According to one aspect (Claim 4) of the present invention, the change history display selection means 2d is the selection rule stored in the change history selection rule storage means 5e among the change history information and the display user name is input. Based on the selection rule corresponding to the user name input by the means 2c, history information and document information having a change intention that does not conform to the selection rule are selected. Since the selection rule is prepared for each user, the user can list the series of edit histories that meet the user's condition together with the intention of the change.

In the present invention (claim 6), the user information storage means 4c stores the user information instead of preparing a rule for each user, and uses it to make a change intention determination rule and a display selection rule. I was able to select. A storage area can be saved because it is not necessary to prepare a rule for each user. Also, when changing the applied rule, it is sufficient to rewrite the user information, and the operation becomes easy.

In the present invention (claim 7), instead of storing the rule applied to each user, the attribute of each user and the information of the application rule for each attribute are stored. Thereby, the application rule can be changed by the operation of changing the attribute of each user, and the application rule changing operation becomes easy.

In the present invention (claims 8 and 9), the user's attributes are described for each document or for each part (ie, partial structure) of each document, so that the user's attribute is described for each document or its partial structure. Even if the attributes are different, the rule for determining the change intention can be changed appropriately, and accurate determination can be made.

The present invention (claims 3, 5, and 1)
In claim 0), the tendency of the user is grasped from the action of the user, and the applied rule and the user information can be changed accordingly. This allows the rules to be applied to be automatically changed according to the tendency of the user.

【Example】

(Overall Structure) The features of the present invention will be specifically described below based on embodiments with reference to the drawings. FIG. 1 is a block diagram including a plurality of aspects of a document management apparatus for implementing the present invention.

This apparatus is (1) a document information storage means 3e for storing a plurality of documents, a document change history storage means 3f for storing a change history of documents stored in the document information storage means 3e, and a document information storage means. A document management unit 3c that manages the document stored in 3e and the document change history stored in the document change history storage unit 3f, a change intention determination unit 3b that determines the user's change intention from the information regarding the change of the document, and A document management unit 3 having a change intention determination rule storage unit 3d for storing a rule for determining a change intention;
(2) Document edit input / output unit 1b that presents a document and receives an edit request from the user, document edit processing unit 1d that interprets the edit request from the user and changes the document, and an edit user name input that specifies the edited user A document editing unit 1 having a unit 1c, and (3) a change history display processing unit 2a for performing a process for displaying the document change history stored in the document management unit 3 and a document change history for presenting to the user. A change history display unit 2 having a change history display input / output unit 2b is provided as a basic configuration.

Further, for convenience of explanation, it is assumed that a network 5 connecting the respective parts is provided. Of course, even if it is not a network, it suffices to have a means for transmitting information between the respective parts such as a data bus.

Further, in the above basic configuration, a difference detecting means for detecting a difference between a document before editing and a document after editing is further provided as means for obtaining information about a document change necessary for the change intention judging means. Either 3a or an editing action storage means 1a for storing the contents of the editing action performed by the user is provided.

Further, the present apparatus has a configuration for properly displaying only necessary information according to the user.
A display user name input unit 2c for identifying a user who views a display, a change history display selection unit 2d for selecting a change history other than those satisfying a specific condition, and a change history selection rule for storing a rule for selection. Storage means 2e
Is provided in the change history display unit 2 as needed (configuration corresponding to claim 4).

The apparatus stores user information instead of preparing the change intention determination rule and the change history selection rule for each user as described above, and uses the user information to display the change intention determination rule and display. The selection rule can be changed and implemented. In that case, a user information storage unit 4c for storing information of each user and a user information management unit 4b for managing information stored in the user information storage unit are provided (claims 6 and 5). , 6, 7).

Furthermore, the present apparatus can automatically change the change intention determination rule according to the tendency of the user.
It is possible to add and implement the user tendency grasping means 4a for changing the rule for judging the intention of the change based on the user's action (components corresponding to claims 10 and 9).

Next, the operation of the present apparatus configured as described above will be described. First of all, to explain the outline of operation,
The document edit input / output unit 1b displays a document to the user based on a request from the document edit processing unit 1d, receives an edit for the document, and transmits the document to the document edit processing unit 1d. The editing user name input means 1c allows the user to input his or her own user name. Change intention selecting means 1e
Presents the change intention determined by the change intention determining means 3b to the user, confirms the change intention by the user's selection, and transmits the result to the document managing means 3c. Editing act storage means 1a
Stores the editing action input by the user through the document edit input / output unit 1b. The document edit processing means 1d performs actual document edit processing and communication of each means. As a result, the document editing unit 1 can present the document to the user, receive the change request from the user, and edit the document.

The document management means 3c is the document information storage means 3
Document information and document change history storage means 3 stored in e
It manages the document change history information saved in f, and
Contact each means. The difference detecting means 3a detects the difference between the document before editing and the document after editing and sends it to the change intention judging means 3b. The change intention judging means 3b judges the change intention from the difference information or the editing action information based on the judgment rule stored in the change intention judging rule storing means 3d. As a result, the document management unit 3 can manage the document group and the change history thereof, and can determine the change intention when a change is made.

The change history display input / output unit 2b designates a document group to be displayed and actually displays it. The display user name input means 2c inputs the user name to be displayed. The change history display processing means 2a receives the information of the document group to be displayed and the change history information, creates a display, and communicates between each means. Further, the change history display selection means 2d selects the document or the change history to be displayed based on the selection rule stored in the change history selection rule storage means 2e. As a result, the change history display unit 2 can appropriately select and display the document group and its change history.

Next, the operation will be described in more detail with reference to the flow chart of the process and a specific example. FIG. 2 is a flowchart showing a process in which a user edits a document and judges the user's change intention from the difference between the document before editing and the document after editing. First, the user inputs a user name for identifying his / her name from the editing user name input means 1c (step S2a). Next, the user designates a document and edits the document. The document management means 3c is the document information storage means 3
The document information stored in e, for example, in the format shown in FIG. 3 is retrieved and transferred to the document edit processing means 1d. The document edit processing means 1d receives the edit request from the user while displaying the document on the document edit input / output means 1b, and edits the document (step S2b).

When the editing is completed, the document is sent again to the document management means 3c. Therefore, the difference between the document before editing and the document after editing is detected by the difference detecting means 3a (step S2c). The difference detection method is as follows, for example. First, the document before editing is examined in order from the front, and it is determined whether or not units such as characters, lines, and sections are present at the same position in the document after editing. If it does not exist at all, it is determined to have been deleted, and if it is at a different position, it is considered to have been moved. On the contrary, the edited document is sequentially examined from the front, and it is determined whether or not units such as characters, lines, and sections are present in the document before editing. If it does not exist, it is determined that it has been newly added. FIG. 4 is an example of the detected difference information.

Next, the change intention judgment rule group stored in the change intention judgment rule storage means 3d in the form of FIG. 5 is searched for the one applied to the user input in step S2a. In the example of FIG. 5, since each rule has a user name (identifier), it can be searched (step S2d). The change intention determination means 3b applies this change intention determination rule to the difference information to determine the change intention (step S2e). FIG. 6 is an example of the determination result of the change intention.

Finally, the document management means 3c stores the edited document in the document information storage means 3e, and the change history of the document is shown in FIG. 7 together with the highest priority among the change intentions judged earlier. The document is saved in the format in the document change history saving means 3f (step S2f).

FIG. 8 is a flow chart showing a process in which the user edits a document and judges the user's intention to change from the editing action when the editing action storing means 1a is provided instead of the difference detecting means 3a. is there. First,
The user inputs a user name for identifying his / her name from the editing user name input means 1c (step S8a). Next, the change intention determination rule storage means 3d is searched for a change intention determination rule group applied to this user by the input user name in the same manner as in step S2d described above (step S8b). Then, the user specifies a necessary document and edits the document. The document management means 3c retrieves the document information stored in the document information storage means 3e, for example, in the format shown in FIG. 3, and transfers it to the document edit processing means 1d. The document edit processing means 1d is a document edit input / output means 1b.
The document is displayed on (step S8c). The document edit processing means 1d receives the edit action from the user from the document edit input / output means 1b (step S8d), edits and displays the document, and at the same time, edits the contents thereof.
To the format shown in FIG. 9 (step S8).
e). This is repeated until the editing is completed, and when the editing is completed, it is returned to the document management means 3c together with the contents of the editing action saved in the format of FIG. 9 in the previous step (step S8f).

Upon receipt of the edited document and the editing action, the document managing means 3c first changes the editing action by the intention determining means 3b.
Transfer to. The change intention determination means 3b determines the user's change intention by applying the change intention determination rule retrieved earlier to the content of the editing action (step S).
8g). FIG. 6 is an example of the determination result of the change intention. Finally, the document management means 3c saves the edited document in the document information storage means 3e, and the change history of the document is shown in the format of FIG. 7 together with the highest priority among the change intentions determined earlier. It is stored in the document change history storage means 3f (step S8h).

FIG. 10 shows a case where an editing action saving / selecting means for selecting only the editing actions necessary for the rule applied to each user and saving them in the editing action saving means 1a is provided.
6 is a flowchart showing a process in which a user edits a document and determines the intention of changing the document. The basic flow is almost the same as the process of determining the user's change intention from the editing action in the case of the flowchart of FIG. The difference from the process shown in FIG. 1 is that in step S10c, the change intention determination rules applied to this user are searched in order,
The result is to select an act to be recorded and an act not to record the result as in the example shown in FIG. 11 and save it. Then, in the process of step S10e, a process for not recording an editing action not necessary for the change intention determination rule applied based on the selection result is performed. In this example, a search is performed for selecting an action when the user selects the user name, but it may be created at the same time when the rule for each user is saved.

FIG. 12 is a flowchart showing the processing for displaying the change history of a document together with the change intention. The user first inputs a user name for identifying his / her name from the display user name input means 2c (step S12).
a). Then, the change history selection rule storage means 2e is displayed in FIG.
Among the plurality of selection rule groups stored in the format of No. 3, the one applicable to the user is searched (step S12b). Next, a series of documents to be displayed is designated by the change history display input / output unit 2b. The document management unit 3c searches the document change history storage unit 3f and the document information storage unit 3e, and returns the document information, the change history, and the change intention information (step S12c). The change history display sorting means 2d sorts the document information based on the sorting rule retrieved earlier, and sends only the document information that meets the user's request to the change history display processing means 2a (step S12).
d). Then, for example, as shown in FIG. 14, the information before and after the editing is displayed with icons, and the information is connected to the change history display input / output unit 2b in a format in which the information is connected by a line segment expressing the change intention. Display (step S12)
e).

In FIG. 15, when the user information storage means 4c is provided and the modification intention judgment rule is determined by the user information, the user edits the document, and the document before editing and the document after editing are edited. 8 is a flowchart showing a process of determining a user's change intention from the difference. The same applies to the case where the intention of change is determined from the editing action, and thus the description thereof is omitted here. The basic processing flow is the same as the processing described in FIGS. 1, 8 and 10. The difference is that the user information stored in the user information storage means 4c is retrieved by the processing shown in step S15d. Here, the user name is sent to the user information management means 4b, and the user information management means 4b is then sent to the user information storage means 4
The user information stored in c is searched, and the change intention determination rule group to be applied is searched. As the user information, as shown in FIG. 16, information indicating which user uses which rule group is described, and as shown in FIG. 17, which user has what role. There are two modes of implementation in the case where the information is stored separately for each role and which rule group is applied to each role. In the former case, the user information management means 4b can retrieve the rule group number of the corresponding change intention determination rule group from the user information in the format of FIG. 16 using the user name. In the latter case, when a user name is specified, the role of the user is searched, and then the rule group applied to that role is searched. Since the rule group is stored in the change intention determination rule storage unit 3d in the form of FIG. 18, the required rule group can be obtained by searching the rule group number.

FIG. 19 is a process for displaying the change history of a document together with the intention of change when the user information storage means 4c is provided and the selection rule for change history display selection is determined by the user information. It is a flowchart showing. The basic processing flow is the same as the processing described in FIG. The difference is that the user information is retrieved by the processing shown in step S19b.
Here, the user name is sent to the user information management means 4b,
The user information management means 4b searches the user information storage means 4c for a selection rule group to be applied. Similar to the case of editing, there are a mode of directly searching for a rule group to be applied from a user name and a mode of searching for a role of a user and then searching for a selection rule group to be applied to the role. Finally, for example, as shown in FIG. 14, the icons of the respective documents are displayed in a form in which they are connected by a line segment expressing the change intention. In addition to the user role described above, the user information
It can be based on various attributes such as affiliation, job title, gender, age ...

FIG. 20 shows a structure in which the document management means is provided with a function of adding user attribute information to a document or a part (partial structure) of a document, and a change intention determination rule is selected based on the attribute information (claim) (Corresponding to items 8 and 7) is a flowchart showing a process in which a user edits a document and determines the user's intention to change from the difference between the document before editing and the document after editing. The same applies to the case where the intention of change is determined from the editing action, and therefore the description thereof is omitted here. The basic processing flow is the same as in the case of FIG. The difference is that the process shown in step S20d retrieves the role information of the user assigned to the document, and the process shown in step S20e retrieves the change intention determination rule corresponding to the role information. is there. In the case of a configuration in which user attribute information is added to each document (claim 8), role information 21b1, ..., 21b4 of each user is added to each document 21a1, ..., 21a4 in the form as shown in FIG. There is. In the case of a configuration in which the attribute information of the user is added to a part of each document (claim 9), the constituent units 22a11, 22a12, 22a of each document are as shown in FIG.
13 ... Role information 22b1, 22b2 of each user,
22b3 ... Are added. By retrieving this information, the role of the user of the changed document or location can be obtained (step S20d). Then, based on the role information, the user information management means 4b
23 retrieves the user information stored in the user information storage means 4c in the format of FIG. 23 and retrieves the change intention determination rule to be applied (step S20e).

FIG. 24 shows a case where the user tendency grasping means 4a is provided (Claims 10 and 11), and the change intention judgment rule is changed from the user's act (action of selecting the change intention indicated by the apparatus). It is a flowchart which shows the process to do. Here, a process in which the user edits a document and determines the user's intention to change based on the difference between the document before editing and the document after editing is taken as an example. The same applies to the case where the intention of change is determined from the editing action, and therefore the description thereof is omitted here. Step S24
The steps from a to step S24f are exactly the same as in the case of FIG. The change intentions determined by the device are provided to the user in the order shown in FIG. 25 in descending order of priority (step S24g). Then, the user selects the one closest to his or her intention (step S24h). The selection result and the edited document are stored by the document management unit 3c in the document change history storage unit 3f and the document information storage unit 3e, respectively (step S24i). Further, the selection result is transferred to the user tendency grasping means 4a (step S24j).
The user tendency grasping means 4a judges the tendency of the user from the selection result of the user (step S24k) and changes the change intention judging rule group stored in the change intention judging rule storing means 3d in the form shown in FIG. Alternatively (in the case of claim 10), the portion related to the change intention determination rule of the user information stored in the user information storage means 4c in the form shown in FIG. 16 is changed (in the case of claim 11) (step S24l).

As an example of the process of judging the tendency of the user and correcting the rule, there is a process of increasing the priority of the rule of the judgment selected by the user and lowering the priority of the rule not selected by the user. it can. Also,
As an example of the process of determining the user's tendency and changing the user information, there is a process of exchanging the rule group to be applied when the ratio of the user's selection of the change determined by the device is less than a certain value. You can

In the above description, the contents of the rule and the applied rule are changed based on the user's act of selecting the change intention determined by the device.
