Description

  The present invention relates to an apparatus for creating and editing a document while referring to information.

  Conventional technologies mainly include a version control technology, a memory reproduction technology, a document search technology based on an event, and the like. First, version control technology will be described. Among the technologies in this field, the most basic one is a diff command in UNIX (registered trademark) as an operating system. This command takes the differences between the files and displays their contents. Furthermore, it is also possible to output an editor command representing the difference. Similarly, UNIX (registered trademark) tools include version management tools such as SCCS and RCS. With this tool, versions of a file can be sequentially stored, and a required version of a file can be obtained when required (for example, Non-Patent Document 1).

  Next, a memory reproduction technique will be described. Representative technologies in this field include Reflexible CSCW (for example, Non-Patent Document 2) and PEPYS (for example, Non-Patent Document 3). Reflexible CSCW collects and displays the file update date of the computer. The user looks at the result and recalls the action he has performed. PEPYS is a technology that automatically records a diary by combining badges and other information that automatically notify the user of the location by infrared rays, and assists human memory ability.

As a document search technique based on an event, there is a document search method in which event data such as a database update / search is stored, and a specific state of the database is searched and reproduced using the event data as a search key ( For example, Patent Document 1). This gives a document describing the details of the event.

And Schmidt, K .; (Editors), September 25-27, 1991, Amsterdam, The Netherlands, pp. 139-157. 175-188

  With a diff command, SCCS, RCS, Reflexible CSCW, etc., when a change occurs in a file, it is possible to grasp the content and timing of the change. However, when the file is merely referred to, it is not recorded at all. PEPYS automatically creates a diary, but cannot keep track of information references. The document retrieval method of Document [2] is for reproducing the state of the database at that time based on the history information of the event and obtaining document information in which details of the event are recorded. However, it is not a reminder of the event itself, but is intended to obtain the state of the database at that time, assuming that the event is remembered.

  Then, the inventor of the present application discovered that attention should be paid to the act of referring to other information. Here, an object of the present invention is to record a history of an act of referring to other information and provide the history to a user when necessary.

The history search means 8 sends the history information to the history holding means 11 based on the search request received by the history display instruction means 7. The configuration may be such that the history of the held reference information and the editing history of the document are searched.
Further, as shown in FIG. 1, the reference history providing apparatus further includes a selection rule for holding a rule for selecting a part of the history recorded by the history recording unit 12 in addition to the configuration of the reference history providing apparatus. It may be configured to include a holding unit 5 and a display history sorting unit 6 that sorts a part of the history recorded by the history recording unit 12 based on the rule held in the sorting rule holding unit 5. Good.

  Next, a process of referring to information according to the above configuration will be described. At that time, the histories of these actions are collected simultaneously. The reference information stored in the reference information storage unit 3 is displayed to the user by the reference information display unit 4. Then, these reference actions are recorded in the history holding unit 11 by the history recording unit 12. Next, a process for providing the history information held in the history holding unit 11 to the user will be described. The history display instruction means 7 is a part for receiving a history display request from the user. Based on the instruction received here, the history search unit 8 searches the history holding unit 11 to search for history information desired by the user. Then, this information is sent to the display generation means 2, a display is generated, and displayed on the reference history display means 1. Thus, the history of the reference act can be recorded and displayed.

  Next, a process of editing a document while referring to information will be described. At that time, the histories of these actions are collected simultaneously. The reference information stored in the reference information storage unit 3 is displayed to the user by the reference information display unit 4. Then, these reference actions are recorded in the history holding unit 11 by the history recording unit 12. The document information held in the editing information holding unit 9 is edited by the editing unit 10.

Next, a process for providing the history information held in the history holding unit 11 to the user will be described. The history display instruction means 7 is a part for receiving a history display request from the user. Based on the instruction received here, the history search unit 8 searches the history holding unit 11 to search for history information desired by the user. Then, this information is sent to the display generation means 2 to generate a display, which is displayed on the reference history display means 1. Thus, the history of the reference act can be recorded and displayed. Further, since the editing action is also recorded, search and display in combination with the editing action can be performed.

  Before the history is searched and finally displayed, the display history selecting means 6 sorts a part of the reference information out of the history information based on the rules held in the sorting rule holding means 5. It is also possible to arrange the display history selection means 6 between the history recording means 12 and the history holding means 11. As a result, it is possible to display the history of only the act that is actually making a reference or to specify the history according to the purpose.

(Overall configuration)
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing an entire configuration of an embodiment of a reference history providing apparatus according to the present invention. The apparatus includes an editing information holding unit 9 for holding a document to be edited, an editing unit 10 for performing an editing process on a document held in the editing information holding unit 9, a reference information holding unit for holding information to be referred to when editing. 3. Reference information display means 4 such as a CRT for displaying information stored in the reference information storage means 3 as basic components. This is equivalent to a component such as a word processor which is a document creation device. Further, in the present apparatus, a history recording means 12 for monitoring an editing action performed by the editing means 10 and a reference action performed by the reference information display means 4 and recording the history with time, and a history holding means 11 for holding the history. Having. Then, among the histories held in the history holding means 11, a history display instruction means 7 for designating a desired one by the user, and a history held in the history holding means 11 in accordance with a request from the history display instruction means 7 is searched. History searching means 8, a display generating means 2 for generating a display representing the searched history, and a reference history displaying means 1 for displaying the history. In addition, it has a display history selection unit 6 for selecting a history that is not considered to be actually referred to from the searched histories, and a selection rule holding unit 5 for holding a rule for selection. The display history selection means 6 is arranged between the history search means 8 and the display generation means 2. On the other hand, if the display history selecting unit 6 is arranged between the history recording unit 12 and the history holding unit 11, there is an effect that the capacity of the history holding unit 11 can be saved. Needless to say, each holding means is described separately for the sake of simplicity of description, but the reference information holding means 3, the selection rule holding means 5, the edit information holding means 9, and the history holding means 11 are provided separately from a magnetic disk or the like. It is possible to integrate them into one storage device. In addition, the configuration may be such that the reference history display unit 1, the reference information display unit 4, and the display unit (not shown) of the editing unit 10 are integrated into one display device such as a CRT.

  FIG. 2 is an example of document information held in the editing information holding unit 9. In this example, a document is managed by a table including an ID that is an identifier that can uniquely identify the document, a document name, and a body address. Then, the document main body is located at a location specified by the main body address.

  FIG. 3 is an example of the reference information stored in the reference information storage unit 3. In this example, the reference information is managed by a table including an ID, which is an identifier capable of uniquely identifying the document, a storage location, a document name, and a main body address. Then, the reference information exists at a location specified by the address of the main body. The reference information may be stored in the device or in an external database on the network. In this figure, the storage location which is local is stored in the device, and the external DB is stored in an external database on the network. FIG. 3 shows that the document R000235 in the second row and the document R3655985 in the third row of the table are held in an external database on the network. Here, the reference information is, for example, information stored in an external database, personal information such as a memo held by an individual operator, and is recorded in the form of a database or a document. .

(Recording of editing history)
FIG. 4 is a flowchart showing processing for editing a document using the present apparatus. First, the user specifies a specific document by inputting a uniquely determined document name, for example, and starts editing work (step S4a). The apparatus refers to the information held in the edited document holding means 9 in the form shown in FIG. 2 based on this instruction and opens the file specified by the user (step S4b).

  Since the history recording unit 12 monitors these operations, the start of editing is recorded in the history holding unit 11 as an editing history. Here, as a data having items of the document ID, the time, the operation type, and the operation content, it is held as a table as shown in FIG. 5 (step S4c). Here, the start time of editing is recorded in the time corresponding to the document ID, the editing start is recorded in the operation type, and the position of the window in which the document is displayed (ie, for example, in the display device) The upper left coordinates and lower right coordinates of the window) and the range displayed in that window (that is, the displayed portion in the document) are recorded. The contents of the opened document are displayed on a display unit (not shown) of the editing unit 10 (step S4d).

  The user issues editing instructions such as adding, deleting, moving, and copying characters and graphics to the document. These editing instructions are for editing a document performed by a word processor or the like, but are not limited thereto. This apparatus interprets the user's editing command and assigns it to each processing (step S4e). The addition is sent to the addition process (step S4f), the deletion is sent to the deletion process (step S4g), the move is sent to the move process (step S4h), and the copy is sent to the copy process (step S4i) and processed. Next, the content of the editing action is reflected on the display on the display unit (not shown) of the editing unit 10 (step S4j).

  The above processing is repeated until all editing is completed (step S4k). When the editing is completed, the file is closed (step S41), and since the history recording unit 12 monitors these operations, the history holding unit 11 edits the file again as the document ID, time, operation type, and operation content. The end is recorded as shown in FIG. 5 (step S4m), and the process ends. Here, the time at which the file was closed is recorded in the time corresponding to the document ID, and the editing end is recorded in the operation type.

(Recording of reference history)
FIG. 6 is a flowchart illustrating a process of recording various reference actions performed when a document is edited using the present apparatus. First, the user designates a specific document by inputting, for example, a uniquely determined document name during document editing, and refers to other information (step S6a). The apparatus refers to the information in the table held in the form of FIG. 3 in the reference information holding means 3 based on this instruction, and opens the file specified by the user. The apparatus refers to this table and opens the file in which the document body is recorded (step S6b).

  Since the history recording unit 12 (monitoring unit) monitors these operations, the start of reference is recorded in the history holding unit 11 as a reference history. Here, as data having items of a document ID, a time, an operation type, and an operation content, the data is held in a table format as shown in FIG. 7 (step S6c). The contents of the opened reference information are displayed on the reference information display means 4. FIG. 8 shows an example in which reference information 8b, 8c, and 8d are displayed simultaneously with the document 8a to be edited (step S6d).

  The user can process the reference information by changing the display range, changing the display position of the window, changing the display magnification, or duplicating the reference information and copying it to the edited document. Instruct. The device interprets the user's reference command and assigns it to each process (step S6e). The change of the display range goes to the display range change process (step S6f), the change of the display position goes to the display position change process (step S6g), the change of the display magnification goes to the display magnification change process (step S6h), and the copy goes to the copy process (step S6h). S6i) is sent and processed. The contents of this processing are held in the history holding unit 11 because the history recording unit 12 monitors these operations (step S6j). Next, the content of the instruction for the reference information is reflected on the display on the display unit (not shown) of the editing unit 10 (step S6k). Here, the recording method is the same as the method described with reference to FIGS.

  The above processing is repeated until all reference actions are completed (step S61). At the end of the process, the file is closed (step S6m), the end of the reference is recorded in the history holding unit 11 again (step S6m), and the process ends.

(Determine display reference history)
FIG. 9 shows only the history information held in the history holding means 11 relating to the designated document. Further, based on the rules held in the selection rule holding means 5, the user can actually obtain the information. 9 is a flowchart showing a process of selecting an action that is not considered to refer to the. First, the user specifies a document whose reference history is to be displayed (step S9a). The user will be described below assuming that a document whose document name is a patent search report and whose document ID is E781578 is specified by the history display instructing unit 7 among the documents held in the editing information holding unit 9. . The history search unit 8 receiving the instruction extracts the document related to the specified document from the editing history stored in the history holding unit 11 in the form shown in FIG. It can be seen that the editing of the previously specified document was started at 17:31:00 on November 30, 1993, and ended at 19:32:59 (step S9b).

  Then, the reference action performed during this time is searched from the reference history stored in the history storage unit 11 as shown in FIG. The search result is as shown in FIG. FIG. 11 illustrates the history information shown in FIGS. 5 and 10 in an easily understandable manner. From the time the edited document (the document with the ID of E781578) is opened to the time the document is closed, four documents having the IDs of R47562, R012456, R000235, and R22359 are referred to, and various reference actions are performed. Understand (Step S9c). Then, in the following processing, the display history selection unit 6 performs an action that is not considered to be referred to from the history information according to the rule held in the selection rule holding unit 5 in the form of FIG. Or, select actions that are not related to the user's intention. The following processing (reference history display processing) is performed without performing any processing thereafter (that is, processing after step S9d) and using the result of the search performed by the history search means 8 (FIG. 10) as it is. It is also possible to do. Further, the following processing can be performed when the history recording unit 12 records in the history holding unit 11.

  First, the counters N and M are set to 1 (step S9d). Next, the N-th reference history is read (step S9e). Next, the M-th rule is read (step S9f). Then, it is determined whether a rule is applied to the reference history (step S9g), and if so, the reference history is deleted (step S9h). This process is repeated while incrementing the value of M by one (step S9j) until the rule ends (step S9i). When all the rules have been applied, the counter M is set to 1 (step S9k). Further, this rule determination loop is repeated while incrementing the value of N by one (step S9m) until the reference history of FIG. 10 ends (step S91), and finally the final result is stored (step S9n). .

  Some specific examples in which the rules are applied and the reference history is deleted by these processes will be described. No. in FIG. In the case where rule 23 in FIG. 12 (the action of “opening” when closed within 5 seconds is excluded) is applied to the reference history 1, this document is opened on November 30, 1993 at 17:43:00. Have been. When the subsequent reference histories are scanned, No. in FIG. The history of No. 8 indicates that this document was closed at 18:39:11 on the same day. This history does not apply to the rules, so do not delete it. No. in FIG. When the rule 23 is applied to the reference history of No. 3, this document is opened at 18:18:45, and the document No. 3 of FIG. 4, it can be seen that it is closed at 18:18:49. Since this history satisfies this rule, the history is deleted by checking the deletion column in FIG. 10 (changing "-" in the deletion column of FIG. 10 to "X") (step S9h). Of course, by applying rule 1 of FIG. 12 (if the action of “opening” a document is excluded, all actions up to and including the action of “close” on the document are excluded), this document is closed in FIG. History No. 4 is also deleted in a later process (step S9h).

  Next, in FIG. A case in which the rule 24 of FIG. 12 (the “open” action hidden in another window and not displayed for 30 minutes or more) is applied to the reference history of No. 6 will be described. This document is displayed at the display position upper left coordinates (600, 250) and lower right coordinates (800, 450). Among the reference histories thereafter, those that may hide this document are identified by No. 1 in FIG. 7 and the act of opening the document No. 7 in FIG. 9 is a window change. No. in FIG. 6 and No. 6 in FIG. When an overlapping portion with the display position of the result of the act 7 is detected, it is found that there is no overlapping portion. No. in FIG. 6 and No. 6 in FIG. It can be seen that there is no overlapping position with No. 9. Therefore, in FIG. The history of No. 6 is not deleted. In this case, the deletion is not performed because there is no overlapping position. However, when there is an overlapping position, the reference history from the occurrence of the overlapping relationship is sequentially scanned, and the time until the overlapping position disappears is calculated. If the time is 30 minutes or more, the reference history is deleted.

  A description will be given of a case where the rule 25 (even if excluded by another rule, it is not excluded if a copying action occurs) or an operation of copying is performed. In this case, while the reference history prior to the action is sequentially scanned, the reference action related to the document that has been deleted is unchecked in the deletion column of FIG. 10, that is, the deletion of FIG. Is restored by changing "X" in the column of "" to "-". This process is repeated between "open" actions. Next, the reference actions subsequent to the copying action are sequentially scanned, and the reference actions relating to this document are changed so as not to be deleted. Specifically, “X” in the column of deletion in FIG. 10 is changed to “−”. This process is repeated until "close" is found.

  The result processed in this way is as shown in FIG. In this figure, the rule 23 shown in FIG. 12 is applied, and among the reference acts in FIG. 10, the reference act for the document with the document ID R012456 is deleted.

(Reference history display)
FIGS. 14 and 15 are flowcharts showing a process for displaying the reference action obtained in the process of FIG. 9 to the user. FIG. 14 shows a process of creating a miniature of the screen of the reference action and displaying it at once, and FIG. 15 shows a process of sequentially displaying the same screen as that actually edited to the user. Things. These processes are performed by the display generation means 2 displaying the information on the reference history display means 1. The display generation unit 2 uses, for example, the reference history shown in FIG. 13 which is only significant history information processed by the display history selection unit 6. Alternatively, the display generation unit 2 may use, for example, the reference history in FIG. 10 which is history information that has not been processed by the display history selection unit 6.

  First, the processing of FIG. 14 will be described. First, the counter N is set to 1 (step S14a). The editing history held in the form shown in FIG. 5 is read into the history holding unit 11, and a miniature of the edited document (a reduced rectangle of the edited document) is arranged at the position where the edited document was displayed. A screen is generated (Step S14b). The N-th of the reference history obtained as shown in FIG. 13 in the above-described process is read (step S14c), and the data expressing the state of the reference screen is updated. For example, the state of the reference document at the position indicated by the vertical dotted line in FIG. 11 is expressed as shown in FIG. 16 (step S14d).

  Then, an image is generated by combining the miniature image of the reference document with the image of the edited document generated in step S14b (step S14e). Further, a reference document name is assigned to each miniature (step S14f). This process is repeated while incrementing N by one (step S14h) until the reference history data ends (step S14g). The final image is provided to the user and the process ends (step S14i). FIG. 17 is an example of a screen displaying the reference history in this manner. From 17a to 17f, the history is displayed as a miniature screen. However, here, for simplification of the display, the movement of the display range in each window is not displayed.

  The processing of FIG. 15 will be described. First, the editing history stored in the history holding unit 11 in the form shown in FIG. 5 is read, an edited document screen is generated at the position where the edited document was displayed (step S15a), and the counter N is set to 1. (Step S15b). Here, after waiting for an instruction from the user's instruction, the reference history is displayed in order. If the instruction from the user is to terminate the display, the display processing is terminated at that point. If the instruction from the user is the next screen display, the process proceeds (step S15c).

  First, the N-th reference history is read (step S15d). Then, data expressing the state of the reference screen is updated in the same manner as in the processing of FIG. 14 (step S15e). Based on the data, an image reproducing the state of the reference screen is generated (step S15f). Further, the data actually displayed there is retrieved from the reference information holding means 3 and added to the generated image (step S15g). This image is displayed to the user (step S15h). This process is repeated while incrementing N by one (step S15j) until the reference history data ends (step S15i). The displayed image is superficially exactly the same as the image shown in FIG. 8 when editing is actually performed.

  In the reference history providing apparatus of the present invention, a history of information referred by a user is held, and a series of reference actions can be displayed. I remember what kind of information affected a series of tasks at the time of the task, but often forget it over time. In most cases, this information is not explicitly stated in the document. According to the first invention, it has become possible for the user to know what kind of information has been affected. This is very effective when writing sentences while referring to various information. In other words, it is possible to recall the meaning of a series of reference actions, and it is possible to recall information that is not recorded in the record, such as the influence of other information. In addition, damages such as unknowingly quoting another person's idea can be suppressed. In the second invention, by referring to the combination of the editing history of the document and the history of the information referred to, it is possible to search for and display a reference action related to document creation. This makes it possible to easily search for a reference action performed during the creation of a document. Further, in the third invention, it is possible to select a part of the reference action. This makes it possible not to display a reference act that is clearly unrelated, or to display only a specific reference act. Therefore, the display can display only a reference action that is considered significant to the creator, and can simplify the display of the reference history.
