  When the operator obtains a document to be registered and performs an operation for registration in the document management server 2 via the operation panel 17, this operation is accepted in step S01. In step S02, the scanner unit 14 reads the document and converts it into an electronic file. Instead of being read by the scanner unit 14, a document stored in the box 151 or the like or a document on the network 4 may be taken in as a document file to be registered.

  Next, in step S03, a table of contents is created from the document file, and in step S04, a document identification code is embedded in the document file as a background pattern and transmitted to the document management server 2 together with the created table of contents.

  The document file and table of contents data transmitted to the document management server 2 are stored in the storage unit 24 of the management server 2 and registered in association with each other. A plurality of document files are registered and stored in the document management server 2 by such processing.

  FIG. 5 is a diagram showing a screen displayed on the display unit 171 of the operation panel 17 of the MFP 1 when the worker performs an operation of registering and storing the document file in the document management server 2.

  When the operator performs an operation for registration, a screen D <b> 1 in FIG. 5 is displayed on the display unit 171 of the operation panel 17. On this screen, the message “Enter the information of the document to be registered.” Is displayed, along with the project code, document classification code, supplier code input fields, and the “Forward” and “Cancel” buttons. Yes.

  The project code indicates the project that is in charge of managing the current document file, the document classification code indicates information that identifies the type of the document file to be registered, and the supplier code is the current document file. This indicates information on a business partner (exchange partner), and each of these codes functions as a document identification code for identifying a document file.

  Each code is determined in advance by the department to which the worker belongs, and is input in accordance with the rules. An example of each code is shown in FIG. In the example of FIG. 6, “C098” indicating “UI development project A”, “C099” indicating “system development project A”, and the like are shown as project codes, and “contract (business consignment)” is shown as a document classification code. “0001” indicating “quotation (business consignment)”, etc., “001” indicating “Company A”, “002” indicating “Company B”, in-house (A “1000” or the like indicating the department) is shown.

  The operator inputs each code using a numeric keypad. Each input code is connected with "-(hyphen)". The document identification code is registered in association with the document file registered in the document management server 2, and the code itself is embedded in each page of the document file as a background pattern by the MFP 1. The registered document file can be retrieved by searching using the document identification code as a key.

  Returning to FIG. 5, when the operator finishes inputting each code and presses the “forward” button on the screen D1, the screen transitions to the screen D2. On this screen D2, selection buttons for “paper medium” and “electronic file” are displayed together with a message “Please select a medium for the document to be registered”.

  When the operator selects “paper medium” and presses the “forward” button, the screen transitions to a screen D3. On the screen D3, a message indicating that the document to be registered is set in the ADF of the scanner unit 14 is displayed. When the document is set in the ADF and the “scan start” button is pressed, reading by the scanner unit 14 is started, and the screen D4 is displayed. Transition to.

  On the other hand, in the screen D2, when the operator selects “electronic file”, inputs the name of the folder that is the storage destination (reference destination) of the electronic file, and presses the “forward” button, the designation is made from the reference destination. While the document file is taken out, the screen changes to a screen D4.

  On the screen D4, a message indicating that registration is being performed is displayed.

  During this time, the MFP 1 creates a table of contents for the document file of the document read by the scanner unit 14 or the document file acquired from the storage destination. The table of contents is created by analyzing the paragraph structure in the document and extracting items such as bookmarks or titles of the respective paragraphs. Such table of contents creation processing is disclosed in, for example, Japanese Patent Application Laid-Open No. 2011-39580. Such a known technique may be used. In this case, if the document file is image data, it is converted into text data using a character recognition function (not shown), a table of contents is created, and stored in the document management server 2 in the state of text data.

  After the table of contents is created, the document file is transmitted from the MFP 1 to the document management server 2 and stored and managed by the document management server 2 as described above. Further, as described above, the document identification code input by the operator is embedded as a background pattern in each page of the document file and transmitted to the document management server 2. The purpose of embedding the document identification code is to obtain an updated version (official version) of the document file later and acquire the document file before update from the document management server 2 for extracting the difference before and after the change. This is for facilitating retrieval of the corresponding document file by the document management server 2.

  Thus, document file registration / accumulation processing is executed.

  Next, an operation for extracting a difference between an updated version document file (first document file) and a provisional version document file (second document file) registered in the document management server 2 will be described.

  FIG. 7 is a diagram for explaining the flow of the entire system.

  For the updated version (official version) document file obtained by the operator, a table of contents is created and registered in the document management server 2 in the same procedure as described with reference to FIGS. In this case, the worker assigns the same document identification code as that given to the provisional version of the document file to the official version of the document file. Also, a version number may be added to indicate a new version.

  Next, the MFP 1 obtains the previous version (provisional version) of the document file obtained this time from the document management server 2. At this time, the document management server uses the document identification code which is the document information input by the operator as a key. 2 sends an acquisition request. The document management server 2 searches the storage unit 24 of the server 2 using the received document identification code, extracts a document file including the designated document identification code as a background pattern, and transmits it to the MFP 1.

  In parallel, the MFP 1 transmits the list data of the table of contents created from the official document file to the worker's terminal device 3 via the network 4.

  Upon receiving the list data of the table of contents, the terminal device 3 of the worker displays the list of the table of contents on the display device in a selectable manner as shown in FIG.

  The worker selects an item that seems important from the table of contents. FIG. 8B shows a selected state, and shows an item in which a black portion is selected. The selection result is transmitted from the worker's terminal device 3 to the MFP 1 as indicated by an arrow X in FIG.

  When the MFP 1 receives the data of the item selected from the terminal device 3 of the worker, the MFP 1 determines that the selected item is a difference extraction target item, and only the paragraph corresponding to the item is the official version document file and document. The provisional version of the document file acquired from the management server 2 is compared, and the difference between the two is extracted. Difference extraction is performed by full-text comparison of the entire paragraph including the item, and a portion that does not match is extracted as a difference.

  The difference result obtained by the extraction process is transmitted from the MFP 1 to the operator's terminal device 3 as indicated by an arrow Y in FIG. The worker's terminal device 3 displays the received difference result on the display device, and the worker sees the result to see how the document has been changed from the previous version of the document and whether any changes have been made. Confirm. A similar difference result can also be printed by the printer unit 16 of the MFP 1.

  FIG. 9 is a display example of the difference extraction result. In this embodiment, as shown in FIG. 8 (B), the operator can select “dealing form”, “development period”, “delivery of deliverables”, “compensation”, “Man-hours”, “total amount”, “other / special notes” are set, and the comparison results are shown. FIG. 9A shows a provisional version document file, FIG. 9B shows an official version document file, and a darkly described portion is a changed portion. For example, the changed portion may be marked with red by changing the color, or the display form other than the color may be changed.

  As described above, the difference extraction between the official document file and the provisional document file is performed only for the paragraph corresponding to the item selected by the user's intention in the official document file. For this reason, since it is not necessary to extract differences in all document files, the total amount of difference extraction can be reduced, and the confirmation work by an operator displayed on a display or printed on paper becomes easier.

  As shown in FIG. 10, when the operator selects a difference extraction target item from the table of contents, the importance is selected from “high”, “medium”, and “low” by using a pull-down menu or the like. Thus, the importance may be set for the selected item. In this case, the difference result may be displayed in different colors for each paragraph according to each importance level. For example, the difference in the high-importance paragraph is red, the difference in the medium-importance paragraph is yellow, and the difference in the low-importance paragraph is blue. It may be changed.

  FIG. 11 is a flowchart showing document file difference extraction processing performed by the MFP 1. This process is executed by the CPU 11 of the MFP 1 operating according to an operation program recorded on a recording medium such as the ROM 12.

  When the operator obtains an updated version of the document and performs an operation for registration in the document management server 2 via the operation panel 17, this operation is accepted in step S11. In step S12, a document is read and input by the scanner unit 14 and converted into an electronic file. Instead of being read by the scanner unit 14, a document previously stored in the box 151 or the like or a document on the network may be taken as a document file to be registered.

  In step S13, a table of contents is created from the document file. In step S14, a document identification code is embedded in the document file as a background pattern, and transmitted to the document management server 2 together with the created table of contents.

  The document file transmitted to the document management server 2 is stored and registered in the storage unit 24 of the management server 2. A plurality of document files are registered and stored in the document management server 2 by such processing.

  Next, in step S15, the created table of contents data is transmitted to the operator's terminal device (PC), and then in step S16, the document management server 2 stores the previous version of the document file using the document identification code entered by the operator as a key. Request acquisition.

  In step S17, it waits to receive the previous version of the document file from the document management server 2 (YES in step S17), and in step S18, the data of the item selected by the operator from the terminal device 3 of the operator is obtained. Wait for reception.

  When received (YES in step S18), in step S19, a full text comparison check is performed on the paragraph corresponding to the selected item, and a difference extraction process is executed.

  After the extraction process, the extraction result is transmitted to the worker's terminal device 3 in step S20, and then the item data selected by the worker is transmitted to the document management server 2 in step S21.

  The item data transmitted to the document management server 2 is stored in the storage unit 25 in the server 2 in association with the document file.

  In the above embodiment, the execution range (paragraph) of the difference extraction process is determined based on the item selection in the operator's table of contents. However, the method for determining the execution range of the difference extraction process is not limited to the above. .

  As another example, if an item to be transferred to a document to be created later is included in the contents obtained in the document obtained by the operator, that item is extracted from the template of the document to be created later. The paragraph corresponding to the item may be determined as the execution range of the difference extraction process.

  For example, when a certain business is outsourced to Company A, a document such as an in-house application for application may be created. In such a case, information such as “order amount”, “development period”, and “delivery date” described in the contract is often transferred to a specific part of the application form. In this way, based on the entries in a document to be created later, it is determined that the relevant part is important.

  The various application forms are stored in the in-house document management server 2, and the MFP 1 can acquire the various application forms from the document management server 2 via the in-house network 4. It has been.

  The operator sets in advance the type of application created based on the contract in association with the contract, and the MFP 1 receives the updated version of the document file. If so, the application template set in the document file is acquired from the document management server 2, and the template is converted into a navigation PDF. At the time of conversion to the navigation PDF, the entry name is themed in each entry column in the template format, and each title is extracted by the conversion to the navigation PDF as shown in FIG. For example, in FIG. 12, keywords such as “business contents”, “order amount”, “development time”, “right to deliverables”, “transaction form”, and the like are extracted from the template of the application form.

  Then, the MFP 1 searches the extracted keyword from the table of contents of the updated version of the document file, and sets a paragraph in which these keywords exist as items as a difference extraction target.

  Further, as another method for determining the execution range of the difference extraction process, a method of using minutes (including an email recording the contents of the meeting) can be cited.

  In other words, based on the minutes of meetings issued during the period from the previous version (provisional version) document file to the updated version (official version) document file and the contents of the sent and received emails, the scope of execution of the difference extraction process Is to determine.

  When various documents such as minutes and e-mails are registered and stored in the document management server 2, the date and time of issue are registered. In the document file difference extraction process, the MFP 1 obtains the issue date and time of the provisional version of the document file and the issue date and time of the current official version of the document file from the document management server 2 until the official version of the document file is issued. The MFP 1 calculates the period.

  Each document is assigned a management ID for identifying which project belongs to each project, such as a project code, and the document management server also records minutes when meeting with the supplier. 2, the same management ID as that of the related document file is assigned and stored together with the issue date and time.

  The MFP 1 is issued within the period from the issuance of the provisional version document file to the issuance of the official version document file from each date, and the minutes related to the document file are acquired from the document management server 2.

  When the MFP 1 obtains the minutes, it converts it into a navigation PDF in the same manner as the application template, extracts each agenda item of the minutes, and sets each agenda item as an important keyword.

  Then, the MFP 1 searches the extracted keyword from the table of contents of the updated version of the document file, and sets a paragraph in which these keywords exist as items as a difference extraction target.

  As another method for determining the execution range of the difference extraction process, an item that has been determined to be a difference extraction target when the difference extraction process has been performed on a similar document file in the past may be used.

  For example, if you have contracted with the same supplier in a different project in the past, and the document file difference extraction process was performed for the contract at that time, the difference extraction target item used at that time is re- It can be used.

  Difference extraction target items set in the past are stored in the document management server 2 as a history in association with the document file. When an updated version of the document file for performing the difference extraction process is input, the MFP 1 receives past similarities. The document management server 2 is requested to acquire the difference extraction target item used for the document file. The document management server 2 calls the difference extraction target item set for the past similar document file from information such as the document document identification code from the history information, and transmits it to the MFP 1.

  The MFP 1 executes difference extraction processing between the provisional version document file and the official version document file for the paragraph corresponding to the acquired difference extraction target item.

  As described above, there are a plurality of methods for setting the execution range of the difference extraction process. For this reason, when executing the difference extraction process, a selection screen for setting a method for setting the difference extraction range as shown in FIG. 13 is displayed on the terminal device 3 of the worker, and the worker selects the MFP 1 and the MFP 1 is selected. The execution range of the difference extraction process may be determined by the method.
