  When revising the contents of various documents such as legal documents and various financial product contracts, the new and old comparison tables that display new documents and old documents in comparison and underline the revisions in the new documents have been widely used. Yes. When such a document is revised, a part of the old document may be displayed as a new document. For example, cases that are handled differently depending on the time of occurrence of a case due to transitional measures, or cases that are more detailed than in the past, and cases that correspond differently in each case, etc., can be described in a table so that they can be compared and easily read and understood. become.

  However, according to the above prior art, if a specific description is cut from an old document, a new table is inserted, and the description cut in the old document is pasted, the entire specific description is regarded as a newly added part, There was a problem that it took time to fix. The present invention has been made in order to solve the above-described problems of the prior art, and even when a part of an old document is tabulated, when a revised part is displayed in contrast, only a substantial revised part is underlined. It is an object of the present invention to provide a document management system, a document management method, and a program for the same, which can eliminate the need for re-correction and can compress differential data of revision history.

  In order to solve the above problems, a document management apparatus according to the present invention is a document management apparatus capable of comparing and displaying an original document before editing and a document being edited, and the document being edited is the document being edited. A table insertion means for inserting a table including a document data including a tag including a tag for classifying the document and capable of storing character data at a desired position of the document being edited; and the document data with the tag Copy means for copying copy source data as a copy destination data to the table cell, tag insertion means for inserting a predetermined tag before and after the copied copy source data, and the copy destination data A display attribute change for comparing the copy source data with the edited copy destination data, and displaying the difference between the copy source data and the edited copy destination data in an identifiable manner Means And wherein the door.

  According to the present invention, since the clauses and the like are displayed in contrast with the old and new, and the portion that has been newly displayed is also clearly displayed, the correction worker can easily grasp the correction contents. There is an effect that can be.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Since FIG. 1 and FIG. 2 are common to the following Example 1 and Example 2, they will be described first.

[Example 1]
Next, Embodiment 1 will be described with reference to FIG. 3 and subsequent drawings.

  FIG. 3 is an overall flowchart of the document editing process executed by the document management apparatus 130. The document management apparatus 130 executes steps S301 to S309 under the control of the CPU 21.

  First, in step S301, an application for document creation / editing processing stored in advance in the hard disk 28 is read into the RAM 22 and activated, and the process proceeds to step S302.

  In step S302, it is determined whether or not there has been an application termination instruction (pressing operation of the “end” button on the screen of FIG. 9) by the user. If it is determined that there is an end instruction, the process proceeds to step S303. If it is determined that the instruction is not an end instruction, the process proceeds to step S304.

  In step S303, whether or not the document is unsaved is determined from the time stamp of the document file stored in the hard disk 28 and the time stamp of the document file stored in the work file for the document file in the RAM 22, and if not saved ( If the time stamp of the document file stored in the work file for the document file in the RAM 22 is newer than the time stamp of the document file stored in the hard disk 28, “Document has been changed. Do you want to save it?” A small screen (dialog) that displays the message and the buttons “Yes”, “No”, and “Cancel” is displayed. If the “Yes” button is pressed, the open document file (in step S304, the RAM 22). Document files stored in the work area for document files) To terminate the application to overwrite the hard disk 28.

  In step S304, when there is an operation of pressing a button for opening a document or a selection operation of a menu, a reference screen (not shown) for opening a document file is displayed, and a list of documents in a predetermined folder is displayed and selected. The read document file is read from the hard disk 28 and stored in the document file work area of the RAM 22, and the process proceeds to step S305. In the present embodiment, the document file selected will be described as a document file of a contract written in the XML format. However, the document file may be a document file other than the contract, and is not limited to the XML format. A tagged format may be used.

  In step S305, the selected document is displayed on a single screen (FIG. 9). The document structure is hierarchically displayed in a tree form on the left side of the screen of FIG. 9, and the contents of the selected document are displayed on the right side of the screen. In the screen of FIG. 9, the chapters of the clauses and the clauses belonging to the chapters are hierarchically displayed in a tree shape on the left side. Each chapter, each article, and each item of each article are stored in a document file by being delimited by corresponding tags (for example, <kou> and </ kou> for items). When the “Display” menu is selected on the screen of FIG. 9, a submenu “New and old contrast display” can be selected from a submenu (not shown) (or the menu is displayed with the right mouse button and “New and old contrast display” is displayed. The submenu can be selected, or a “new and old contrast display” button (not shown) is displayed on the screen of FIG. The process proceeds to step S306 at a predetermined timing (for example, at intervals of 0.1 second, and so on).

  In step S306, it is determined whether the old and new contrast display is selected by selecting a menu or pressing a button. If it is determined that the old / new comparison table display has been selected, the process proceeds to step S307. If it is determined that the new / old comparison table display is not selected, the process proceeds to step S308.

  In step S307, the old and new comparison table processing is executed on the comparison display screen as shown in FIG. 10 to edit the document (details will be described later according to the flowchart of FIG. 5). The process proceeds to step S309 at a predetermined timing.

  If the old / new comparison table is not displayed in step S306, the process proceeds to step S308, and editing processing such as text input and text deletion is performed in accordance with the input operation of the user in the state displayed on the single document display screen shown in FIG. Do. The process proceeds to step S309 at a predetermined timing.

  In step S309, it is determined whether to continue editing. Specifically, it is determined whether “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed. If “close” is not selected in the menu and the “x” button is not pressed, the process returns to step S306. If “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed, the process proceeds to step S302. This is the end of the description of the flowchart of FIG.

  FIG. 5 is a detailed flowchart of the old / new comparison table processing (step S307 in FIG. 3 executed in the document management apparatus 130 and step S424 in FIG. 4 executed in the document management server 110). The document management apparatus 130 controls the CPU 21. Steps S501 to S509 are executed below.

  In step S501, the screen display data stored in the hard disk 28 is read out to the RAM 22, and the screen is switched to the new / old comparison table display (FIG. 10). The new / old comparison table display screen of FIG. 10 is composed of three columns. From the left, a “new document column” (column for displaying the contents of the document file currently being edited) and an “old document column” (current column). A column for displaying the contents of the original document file of the document being edited) and a “remarks column” (a column for inputting a comment or the like regarding the revision content).

  In the new document field and the old document field, one XML file is displayed on the left and right. Although they are the same XML file, the display method (display attribute) is different between the new document field and the old document field (described later). This display attribute is stored in advance in the hard disk 28 as a display attribute table, and is read and stored in the work area of the RAM when an application for document creation / editing processing is started. Specifically, a new document column / old document column classification, a tag, and a display attribute corresponding to the tag are stored. For example, in the new document column, a tag <hk1.00-01> In the old document field, the <hk1.00-01> tag is associated with non-display, the character color is red, and the strikethrough (the center line of the character is horizontal writing for horizontal writing and vertical writing). , One or two lines in the vertical direction) are stored in association with each other. In the <insert> tag (tag indicating an added portion) in the new document field, the character color is blue and the underline is associated with the tag. In the <delete> tag (tag indicating the deleted portion) in the new document column, the character color is red and a strikethrough is associated with the character.

  In step S502, it is determined whether or not the user has given an instruction to end the display of the new and old comparison tables (pressing operation of an “end” button on a screen not shown). If it is determined that there is an instruction to end the display of the old and new comparison table, the process proceeds to step S503. If it is determined that there is no termination instruction, the process proceeds to step S504.

  In step S503, the new / old comparison table display process is terminated. In step S504, the user's operation content is determined, and the process proceeds according to the determination. If it is determined that a text input operation has been performed in the new document field, the process proceeds to step S505 (additional process). If it is determined that a text deletion operation has been performed in the new document field, the process proceeds to step S506 (deletion process). If it is determined that a table insertion operation has been performed in the new document column, the process proceeds to step S507 (table display process).

  In step S505, a text addition process is performed. Details will be described later according to the flowchart of FIG. After the additional recording process, the process proceeds to step S508 at a predetermined timing. In step S506, text deletion processing is performed. Details will be described later according to the flowchart of FIG. After the deletion process, the process proceeds to step S508 at a predetermined timing.

  In step S507, a tabulation process is performed. The tabulation process is a process of inserting a table at a desired position in a new document and pasting a part of the text of the document into the inserted table for editing. Details will be described later according to the flowchart of FIG. After the tabulation process, the process proceeds to step S508 at a predetermined timing. In step S508, an editing process for inputting or deleting text in the remarks column of FIG. 10 is executed. After the editing process, the process proceeds to step S509 at a predetermined timing.

  In step S509, it is determined whether to continue editing. Specifically, it is determined whether “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed. If “close” is not selected in the menu and the “x” button is not pressed, the process returns to step S504. If “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed, the process proceeds to step S502. This is the end of the description of the flowchart of FIG.

  FIG. 6 is a detailed flowchart of the tabulation process (step S507 in FIG. 5) executed in the document management apparatus 130. The document management apparatus 130 executes steps S601 to S610 under the control of the CPU 21.

In step S601, when the right button of the mouse is clicked on the screen of FIG. 10, the right button menu shown in FIG. 11 is displayed. When the “Add contents” menu is selected and “Table” is selected, the number of columns and the number of rows are displayed. A small screen (dialog) (not shown) displaying an input field and an “OK” button and a “Cancel” button is displayed. When the number of columns and rows are input and the “OK” button is pressed, a new document field is displayed. Insert the table of the number of columns and rows entered in the dialog at the cursor position. Specifically, a table <table></table> and a tag indicating each row and each cell corresponding to the number of columns and the number of rows input in the dialog are inserted at a position corresponding to the cursor position of the document file. For example, in the case of 2 rows and 2 columns, <table> is added to the document file (XML format) stored in the document file work area of the RAM 22.
<Tr>
<Td> blank code </ td>
<Td> blank code </ td>
</ Tr>
<Tr>
<Td> blank code </ td>
<Td> blank code </ td>
</ Tr>
</ Table>
Insert a tag and a blank code. For example, the 2 × 2 table is composed of four columns (hereinafter referred to as “cells”). Each cell corresponds to <td> blank code </ td>. Note that the screens of FIGS. 12 and 13 show a case where a table of 1 row and 2 columns is inserted.

  The post-table insertion process proceeds to step S602.

  In step S602, it is determined whether or not the tabulation process is to be ended (whether an end instruction has been given). Specifically, it is determined whether “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed. If “Close” is not selected in the menu and the “x” button is not pressed, the process proceeds to step S603. If “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed, the tabulation process is terminated via step S606.

  In step S603, as shown in the screen of FIG. 12, the range of the text to be tabulated (text of text to be transferred to the table) is selected (for example, the start point of the text is indicated by pressing the left mouse button). , Specify the end point of the text by dragging, highlight the text as shown in FIG. 12, click the right button of the mouse and select “Cut Tab” from the displayed menu), “Cut Tab” I do. Table cut is a tag that is inserted at the start and end of the text to be tabulated in the new document field and is not displayed on the screen of the new document field. The text to be tabulated is stored in the work area of the RAM 22. The screen shown in FIG. 13 shows the state of the screen after tabulation cutting and before tabulation pasting. That is, in FIG. 13, the cut text is not displayed, and the cut text is not yet pasted in the newly created table.

  For example, <hk1.00-01> is inserted at the start point and </hk1.00-01> is inserted at the end point. Here, hk means “table cut”, “1.00” indicates the version of the document read from the bibliographic information of the document file being edited, and “01” after the “−” indicates the table cut position. Means a serial number for identification. This serial number is unique within each “article” of the contract in this embodiment. For example, if the text to be tabulated by table cut is “except when there is an offer from the customer”, the cell of the part will be “<hk1.00- 01> However, except when there is an offer from the customer. At this time, in the old document column, the display attribute of the portion corresponding to the cut-out cut portion (the portion sandwiched between the <hk1.00-01> tag and </hk1.00-01>) is changed, and the tabulated The cut-out text is displayed in red letters and a strikethrough is inserted. For example, the serial number can be set to about 4 digits, and the serialization position can be attached so that the management of the table pasting position is unique in the entire document file.

  In step S604, it is determined whether or not the tabulation process is to be ended (whether an end instruction has been given). Specifically, it is determined whether “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed. If “Close” is not selected in the menu and the “x” button is not pressed, the process proceeds to step S605. If “Close” is selected from the menu or the “x” button at the upper right of the screen is pressed, the tabulation process is terminated via step S606.

  In step S605, "Add contents" is selected from the menu displayed by the user selecting a cell and clicking the right button of the mouse as shown in FIG. In step S603, copy and paste the text to be tabulated into the specified cell (the cell where the cursor is positioned) of the table inserted into the document in step S603 and store it in the RAM 22 work area. ”Is executed.

  An example of the screen after pasting is shown in FIG. If the text to be tabulated is tabulated, for example, “except when there is an offer from the customer.”, After this tabular pasting operation, the relevant part of the document file will be “<hh1.00- 01> However, except when there is an offer from the customer. Here, “hh1” means tabular pasting, 1.00 is the version of the document file, 01 is the corresponding tabbed cut location <hk1.00-01> and </hk1.00-01>. A unique number to associate with. After the pasting and pasting, the text to be tabulated is displayed in the cell at the pasting position in the new document column, and the text displayed in this cell can be deleted and the editing operation for adding the text can be performed.

  In step S606, the editing operation is determined, and an editing operation other than the editing operation for the tabulated text (for example, when “Close” is selected from the menu or the “x” button on the upper right of the screen is pressed, If it is determined that there is an editing operation other than the tabulated text, it is determined that the “other editing operation” and this processing is terminated. On the other hand, if it is determined in step S605 described above that the editing operation is performed on the text to be tabulated that has been subjected to the “table pasting” operation, the process proceeds to step S607 or step S608. Specifically, the editing operation is determined on a character-by-character basis by comparing the original text to be tabulated stored in the work area of the RAM 22 and the text to which the corresponding cell is pasted (determined every time one character is added or deleted To do). If the editing operation is text input, the process proceeds to step S607. If the editing operation is deletion of text, the process proceeds to step S608. If there is no editing operation, the system waits for an editing operation in step S606.

  In step S607, an additional writing process is performed. Specifically, FIG. 7 which is a detailed flow of step S607 will be described. In step S701 in FIG. 7, the input character is added to the cell being edited. In step S702, it is determined whether or not the added character exists in the original text to be tabulated stored in the RAM 22. If it is determined not to proceed, the process proceeds to step S703.

  In step S702, it is determined whether or not the original text to be tabulated exists based on the match / mismatch of the entire text including the character order. Specifically, it is performed as follows. If the original text to be tabulated is “However, except when there is a request from the customer”, the cell being edited is entered with one character of the document. If not, it is determined that the 9th character “speed” does not exist in the original text to be tabulated.

  In step S703, the added character is inserted between the <insert> tag and the </ insert> tag at the text addition location in the text being edited in the cell, and the display attribute of the input character is set. change. Specifically, the character entered in the cell is underlined and displayed in blue. For example, if the original text to be tabulated is "However, except when there is an offer from the customer", the first character "Speed" is added, "However, from the customer <insert> speed </ insert> Except when there is an offer. " In the state where the four characters “promptly” are added, it is “except when the customer makes an <insert> prompt” request. Thus, when characters are continuously added to the same location, only one set of <insert> tag and </ insert> tag is inserted. This is the end of the description of FIG. 7 which is the detailed flow of S607.

  Returning to the description of the flow of FIG. In step S608, a deletion process is performed. Specifically, description will be made with reference to FIG. 8 which is a detailed flow of step S608. In step S801 of FIG. 8, a <delete> tag and a </ delete> tag are added before and after the character deleted in the cell being edited. In step S802, the added character is stored in the RAM 22 in the original. It is determined whether or not the text to be tabulated exists, and if it is determined that the text does not exist, the process proceeds to step S803.

  In step S802, it is determined whether or not the original text to be tabulated exists based on a match / mismatch of the entire text including the character order in a state excluding the <delete> tag and the </ delete> tag. Specifically, it is performed as follows. If the original text to be tabulated is “However, except when requested by the customer”, the cell being edited is deleted with the first character “o” in the fourth character of the document. “However, except when there is an offer from the customer,” the 9th character “O” is compared with the <delete> tag and </ delete> ignored. "Is present in the original text to be tabulated.

  In step S803, the display attribute of the character sandwiched between the <delete> tag and the </ delete> tag, which is the text deletion location in the text being edited in the cell, is changed. A strike-through line is drawn on the character between the tags, and the character is displayed in red. For example, if the original text to be tabulated is “However, except when there is a request from the customer”, the fourth character “O” is deleted and “<delete> O </ delete> customer Except when there is an offer. " In a state where “from customer” is deleted for 5 characters, it is “except when <delete> offers </ delete>.” Thus, when characters are continuously deleted at the same location, only one set of <delete> tag and </ delete> tag is inserted.

  Processing when the same character is input at the character position deleted in S701 will be described. For example, the original text to be tabulated is “However, except when there is an offer from the customer.” The first three characters are deleted once, and the first three characters are struck through (“< delete> However, </ delete> except when there is an offer from the customer.)), when three characters of "However," are newly entered at the top (deleted character string and new In step S702, since it is determined that the three characters “However,” existed in the original text to be tabulated, the leading “However,” The cancel line disappears (the <delete> tag and the </ delete> tag disappear to return to the original state), and no additional attribute is displayed for the three characters “However,” which are input again. Similarly, when the first three characters have been deleted and a new “Ta” character has been entered at the beginning (“However, unless <delete> and </ delete> offers a request from the customer ”And the one-line strike-through line of“ Ta ”disappears.

  Similarly, for example, even if three characters are once added to the original text to be tabulated and the three characters are displayed with the additional attribute, even if these three characters are deleted at the beginning, It is only deleted together with the <insert> tag and the </ insert> tag, and no deletion is displayed. When a part of the three characters is deleted, the characters not deleted are sandwiched between the <insert> tag and the </ insert> tag and displayed with an additional attribute. This is the end of the description of FIG. 7 which is the detailed flow of S607 and the description of FIG. 8 which is the detailed flow of S608.

  Returning to the description of FIG. In step S609, it is determined whether to continue the tabulation process. Specifically, when it is determined that the end is instructed or an instruction to open a new document file is received, it is determined that the editing is not continued, and the process ends. If it is determined that another editing operation has been detected (determined as NO), the process proceeds to step S610.

  In step S610, it is determined whether to continue the editing process for the text in the table. If it is determined that there is an editing operation on the tabulated text or other text in the document, the process returns to step S606, and if it is determined that a menu of a process other than the tabulated process is selected, this process is performed. finish. This is the end of the description of the first embodiment.

[Example 2]
In the first embodiment, the case where processing is executed by a so-called stand-alone document management apparatus (document management apparatus 130 in FIG. 1) has been described. However, the same processing as that performed by the document management apparatus in the first embodiment is document management. An embodiment (so-called client server type system) in which the server 110 and the terminal device 120 execute in cooperation is also conceivable. Hereinafter, the difference from the first embodiment will be mainly described. For the sake of simplicity, description will be made assuming that one terminal device is connected to the document management server 110. In practice, however, a plurality of sessions are established and data is transferred between the terminal devices. Needless to say, processing is performed in parallel. In FIG. 4, dotted arrows between the document management server 110 and the terminal device 120 indicate data exchange, and solid arrows indicate the flow of processing of the document management server 110 and the terminal device 120.

  The differences between the first embodiment and the second embodiment are mainly that the document management server 110 and the terminal device 120 share roles, and that document files are exchanged between the document management server 110 and the terminal device 120. The operation information is transmitted from the terminal device 120 to the document management server 110, and the document file is edited on the server side by the operation information.

  Hereinafter, the overall flow of FIG. 4 will be described. In FIG. 4, steps S401 to S411 are processes executed under the control of the CPU 21 of the terminal apparatus 120, and steps S421 to S427 are processes executed under the control of the CPU 21 of the document management server 110. First, in step S401, the terminal device 120 executes an initial process. Specifically, a document editing software (document editing client software or a browser incorporating a document editing plug-in) is activated, and connected to the document management server 110 to perform authentication processing (send user ID and password). ). The document management server 110 performs authentication determination using the received user ID and password. If the authentication determination is OK, the session management server 110 assigns a session ID to the RAM 22 and secures a session memory for the user in the RAM 22. Is transmitted to the terminal device 120 (screen information read from the hard disk 28 to the RAM 22). The terminal device 120 displays an initial screen using the screen information received from the document management server 110. If the authentication determination is NG, an error message is transmitted to the terminal device 120 and the process is terminated. Hereinafter, a case where the authentication determination is OK will be described.

  In step S <b> 402, the terminal device 120 transmits a document request to the document management server 110. The document request may be transmission of a document name or a document ID, or a document list may be requested from the document management server 110, a desired document may be identified from the document list transmitted from the document management server 110, and the document request may be transmitted. . In step S421, when the document management server 110 receives a document request from the terminal device 120, the document request is stored in the session memory of the RAM 22, and the process proceeds to step S422.

  In step S422, the document management server 110 reads the document request stored in the session memory of the RAM 22, reads the document file of the requested document from the hard disk, and stores the document file in the document file work area of the RAM 22. The document file is transmitted to the terminal device 120. The document file includes a unique document ID and document name for specifying the document. The document management server 110 advances the post-transmission processing to step S423 and waits in a state waiting for receiving operation information.

  In step S403, the terminal device 120 stores the received document file in the work area of the RAM 22 and displays it on a screen as shown in FIG. The process proceeds to step S404 at a predetermined timing. In step S404, the terminal device 120 performs an editing operation (movement of the cursor by clicking the left button of the mouse, menu display request by clicking the right button of the mouse, selection of each button or menu by clicking the left button of the mouse, drag operation of the mouse, keyboard Character input, pressing the delete key or insert key, selecting to save the document in the menu, selecting to end the menu, pressing the X button at the top left of the screen, etc., and determining that there was operation information If so, the process advances to step S405.

  In step S404, the terminal device 120 transmits operation information to the document management server 110 together with the session ID. In step S423, the document management server 110 is in a waiting state for operation information transmitted from the terminal device 120. When operation information is received from the terminal device 120, the process proceeds to step S424.

  In step S424, the document management server 110 executes the new and old comparison table processing shown in FIG. A difference from the first embodiment is that a process similar to that in step S303 in FIG. 3 is executed in step S503. That is, in step S503 in the second embodiment, the document management server 110 determines whether the document has not been saved, the time stamp of the document file stored in the hard disk 28, and the time stamp of the document file stored in the work file for the document file in the RAM 22. If the document file has not been saved (if the time stamp of the document file stored in the work file for the document file in the RAM 22 is newer than the time stamp of the document file stored in the hard disk 28), “the document has been changed. Is read from the hard disk 28 to display the screen information for displaying a small screen (dialog) that displays the buttons “Yes”, “No”, and “Cancel”. 120 and displayed on the terminal device 120. When the “Yes” button is pressed on the screen and the operation information indicating that the “Yes” button is pressed is received from the terminal device 120, the open document file (for the document file in the RAM 22 of the management server 110) is displayed. The document file being edited stored in the work area) is overwritten on the hard disk 28, and the session ends.

  In other cases, a step is performed on the document file stored in the document file work file in the RAM 22 according to the processing content determined in step S504 using the operation information received in step S423 and stored in the work area of the RAM 22. The processing from S505 to S508 is executed. In step S425, the management server 110 generates new screen information using the document file reflecting the result processed in step S424 using the operation information, and transmits the generated screen information to the terminal device 120. After transmission, the process proceeds to step S426. In step S406, the terminal device 120 updates the display of the document comparison screen using the screen information received from the management server 110, and advances the process to step S407.

  In step S407, the terminal device 120 determines whether or not the mouse or the keyboard is operated in the same manner as in step S405, and advances the process to step S408. In step S408, the terminal apparatus 120 determines whether or not the document storage is selected in the menu. If the document storage is selected, the process proceeds to step S409. If there is no selection to save the document, the process proceeds to step S410. In step S409, the terminal device 120 transmits a session ID and a request to save the document being edited (document ID or document name and information to request saving) to the management server 110. In step S426, the document management server 110 determines whether a document save request has been received. If a document save request is received, the document management server 110 stores the save request in the session memory corresponding to the session ID in the RAM 22, and the process is performed. Proceed to S427. If a document save request has not been received, the process returns to step S423.

  In step S427, the document management server 110 overwrites the document file stored in the hard disk 28 with the document file stored in the work area of the RAM 22 with the document file stored in the session memory, and the process returns to step S421.
