Description

  The present invention relates to a technique for handling so-called document data, in particular, data in a format such as form data, and more particularly to a technique for detecting a difference (difference) between a plurality of documents. This document data includes form data, and also relates to a technique for confirming a form change when the form system (creation) is transferred to the new system. The technology is applied to various fields such as finance, distribution, and industry.

  Document systems used in finance, distribution, industry, etc., especially form systems, input data from business applications, core systems, package systems, etc., and map the data to a format predefined by the operator. , Paper, pdf, excel and other forms output system. Examples of the contents defined in advance by the operator include character input, ruled lines, shading, graphic drawing definitions, and display position definition of data to be imported into a form. Hereinafter, information defined in advance by the operator is referred to as format definition, and data that is input to the form system is referred to as business data.

  When the form system is migrated to the new system, it is verified whether the form created in the new system is output in the same way as the form created in the old system. I have confirmed. Specifically, the two forms of the new and old systems are compared manually, and if the part for generating forms is changed with the migration of the new system, it is output as it is changed, and the parts that have not been changed Confirms that it is output in the same way as the form of the old system.

  On the other hand, Patent Document 1 discloses a technique for matching (comparing) document images with a document captured by a scanner (OCR).

JP 2000-285139 A

  In the above-described contents, since comparison is performed by human power, there is a possibility that a work load is applied to the worker and oversight may occur. In order to avoid this, it is conceivable to apply Patent Document 1 and digitize two forms to automatically detect a difference.

  However, in Patent Document 1, it is for preventing double registration by confirming whether the same document is stored as image data, and a difference (difference) cannot be detected in the first place. Even if a difference is detected, the work for analyzing the factor is performed manually, so the work load remains high. Whether the work of analyzing the cause of the difference is a specification that occurs because the worker deliberately changed the format definition on the assumption that a difference between the old and new forms occurs, or a bug in the new system or a format definition This is the work of determining whether or not a bug has occurred due to a setting error, and the work of extracting a program or format definition that affects the difference determined to be a bug. Hereinafter, these operations are referred to as difference factor analysis operations.

  The present invention specifies a cause of occurrence of a difference generated in two or more documents (particularly, a form). At this time, it is preferable to determine the factor by using information related to each document creation system and definition information of the document. In addition, when the target document is created by the old system and the new system migrated from now on, it is more preferable to use a log of the work changed along with the migration as information on the creation system. In addition, it is an aspect of the present invention to use a format definition defined for generating a form as the definition information.

  According to the present invention, when there is a difference in a plurality of documents, the factor can be mechanically displayed with respect to the task of analyzing the factor, so that the manual work is reduced.

It is a structure of a difference factor analysis result. In a 1st Example, it is an example of the screen which displays a difference factor result to an operator.

  FIG. 1 is a configuration diagram of a form inspection system according to the first embodiment. The form inspection system includes a computer 1 that generates a form and a computer 2 that compares a form with a form of an old system, and these are connected via a network or the like. This configuration is an example in the case of the first embodiment, and when a function for generating a form and a function for analyzing a difference factor exist in one computer, there may be a plurality of computers 1 or 2. .

  A computer 1 that generates a form is a computer including a CPU 10, a main memory 11, a storage device 12, an input device 13, an output device 14, and a communication interface 15, and these are connected by an internal bus or the like. The CPU 10 performs various processes by reading the unit stored in the storage device 12 into the main memory 11 and executing it. The storage device 12 includes a form generation unit 101 that generates a form, a format generation unit 102 that generates a form definition, a character definition of a form, a drawing definition of ruled lines, shading, and graphics, and a display position definition of data to be imported into the form Format definition 103 which is the format definition of the form, business data 104 which is output from the business application and displayed on the form, format change log 105 which stores the work contents changed in the format creation unit, pdf, excel, etc. The new system form data 106, which is electronic data of the output form, and the format definition coordinates 107 for storing the coordinates of the contents defined as the form are output. The format definition coordinates 107 may be any information that specifies the position in the form. Hereinafter, a computer that generates a form is referred to as a form generation server.

  The computer 2 for comparing the difference with the form of the old system is a computer comprising a CPU 20, a main memory 21, a storage device 22, an input device 23, an output device 24, and a communication interface 25, which are connected by an internal bus or the like. The Various processes are performed by reading a part stored in the storage device 22 into the main memory 21 and executing it. The storage device 22 compares the new system form data 106 generated in the new system with the old system form data 114 generated in the old system, which will be described later, and extracts a difference, and a format corresponding to the extracted difference Difference factor analysis unit 112 that extracts definition information, difference factor display unit 113 that displays a result of the difference factor analysis unit 112 to the worker, electronic data of a form generated in the old system, or paper generated in the old system Old system form data 114 obtained by converting the form into electronic data using a scanner, the new system form data 106 and the old system form data 114 are compared and the difference coordinates generated by comparing the old system form data 114 and the form name are stored. The difference factor analysis result 116 in which the difference information stored in the difference result 115 is associated with the format definition is stored. Hereinafter, the computer 2 that compares the difference with the old system form is referred to as a form comparison server.

  In FIG. 2, the form generation unit 101 generates a new system form 106, the difference extraction unit 111 performs comparison with the old system form 114, the difference factor analysis unit 112 analyzes a difference factor, and a difference factor display unit 113. Is a flowchart for displaying the cause of the difference. This display allows the operator to confirm the factor. Further, in this flowchart, the CPU of each device described above executes the processing according to the program.

  In step 201, the operator's operation on the format creation unit 102 is received, and a format definition 103 is created based on the business data 104 generated by the business application. The method of operating the form creation unit 102 by the operator is the same as that of a general form generation tool, and setting of the position and attribute of the form and setting of the display position of the business data 104 are performed by the GUI. Specific examples of the business data 104 and the format definition 103 will be described below with reference to FIGS.

  The business data 104 is data output from a business application, backbone system, package system, etc. In FIG. 3, the csv file output from the business application is taken as an example, and the file name is stored as P. The data is three columns of data each having two columns.

  The format definition 103 stores input definitions of characters, ruled lines, drawing definitions such as shading, graphics, and the like, the display position of the business data 104 to be imported into the form, and the like. FIG. 4 shows an example of the format definition 103. The form definition 103 stores a form name 401, a layout definition 402 that defines the layout of the form, a form definition 403 that shows the details of the forms constituting the layout, and a display position definition 404 that indicates which form the business data 104 is displayed on. Has been. In FIG. 4, the format definition for the form name Q is taken as an example, and the layout definition of the form Q, 8 form definitions, and 6 display position definitions are described. Regarding form definition 403, form A is an outer frame, form B is a table, form C to form H are text boxes, line type, line thickness, fill color, font size, font color, font type , Character alignment method is set for each form. With respect to the display position definition 404, the information of the file P shown in FIG. In FIG. 4, the layout definition 402 is graphically displayed, but actually, the coordinates of the starting point of each form, the vertical and horizontal lengths of each form, and the like are defined. The layout definition 402 and the form definition 403 are the same as the information defined when creating a screen by GUI operation in a general drawing tool (software).

  In order to distinguish whether the format definition has been changed to create a new form in the same format as the old form, or whether the format definition has been changed on the assumption that a difference between the old and new forms will occur. The creation unit 102 creates the format change log 105. If the format definition has been changed to create a new form in the same format as the old form, the change is due to migration requirements, and the format definition has been changed on the assumption that a difference between the old and new forms will occur. This is called a change by requirement.

  An example of the format change log 105 is shown in FIG. A change ID 501 for identifying a change work, a form name 502 to be changed, a form name 503 to be changed, an operation content 504 describing details of the change work, a change due to a migration requirement or a change due to a new requirement The change requirement 505 describing whether or not is stored. FIG. 5 is a list of changes related to the form C of the form P. The character alignment is set to the center based on the transition requirement, the font size is set to 12 based on the new requirement, and the font is set to the Mincho. In FIG. 5, the layout definition and display position definition of each form stored in the format definition 103 is generated from the format definition of the old form system using the format definition conversion tool, and then the operator performs fine adjustment. Assumes that If the format definition conversion tool is not applied, the operator changes the layout definition and display position definition of each form, and those changes are also registered in the format change log 105.

  The form creation unit 102 registers the change ID 501, form name 502, form name 503, and operation content 504 for each operation by the worker. The change requirement 505 is defined each time the operator operates the form creation unit. Alternatively, after the operation of the format creation unit 102, a rule for distinguishing a change due to a new requirement and a change due to a migration requirement may be registered, and the change requirement 505 may be input according to the rule. For example, if there is a new requirement that the fonts of the old form are all Gothic fonts, but the characters of the new form are Mincho type, the change log change requirement that changes the form font to Mincho type 505 is assumed to be new.

  In step 202, the form generation unit 101 generates new system form data 106 and format definition coordinates 107 based on the format definition 103 and the business data 104. FIG. 6 shows an example of the new system form data 106, which is new system form data generated based on the example of the business data 104 shown in FIG. 3 and the example of the format definition 104 shown in FIG. FIG. 7 shows an example of the format definition coordinates 107. A generated form name 701, a form name 702 defined in the generated form, a form attribute 703 indicating the type of form, and form coordinates 704 indicating where each form is displayed in the new system form data 106 are stored. ing. The form attribute 703 is a form type such as a text box or a figure. Form coordinates 704 are the coordinates of the display position of each form corresponding to the output medium of the new system form data 106, and the coordinates of XY are (10, 20), (10, 200), (100, 20), If it is a quadrangle composed of four points (100, 200), (10, 20, 100, 200) is displayed. When generating the new system form data 106, the form generation unit 101 acquires coordinates 704 corresponding to the output medium of the new system form data 106 for each form, and combines the form name 701, form name 702, and form attribute 703. sign up. For example, when the output medium is pdf, the coordinates designated by pdf are acquired for each form and registered in the format definition coordinates 107.

  In step 203, the difference extraction unit 111 compares the new system form data 106 and the old system form data 114, acquires the coordinates that are the difference, and registers them in the new and old form difference result 115. An example of the old system form data 114 is shown in FIG. 8, and an example of the old and new form difference result 115 is shown in FIG. The new and old form difference result 115 stores a difference ID 901 for identifying the extracted difference, a compared form name 902, and a difference coordinate 903 where the difference has occurred. The difference extraction unit 111 compares the new system form data 106 and the old system form data 114 and registers the extracted differences in the new and old form difference result 115. When the difference extraction unit 111 compares FIG. 6 and FIG. 8, the font and font size of the character “ID” are different, the font and font size of the character “money” are different, and the font of the number “100000000” Three differences of different sizes are extracted. Next, the coordinates where the characters “ID”, “money amount”, and “100000000” are displayed are acquired and registered in the new and old form difference result 115. For example, if the coordinates of “ID” are (30, 20, 50, 30), the difference ID 901 = 1, the form name 902 = Q, and the difference coordinates 903 = (30, 20, 50, 30) are registered. The same applies to “amount” and “100000000”. In the present embodiment, the difference in characters is taken as an example, but the coordinates where the difference is generated are similarly acquired for differences in figures such as line type and line width.

  There are several conventional methods for comparing the system form data 106 and the old system form data 114. For example, there are a method in which two forms captured by a scanner are compared and compared as an image, a method in which characters are identified by OCR and compared. For any of these methods, this patent can be applied by acquiring the difference coordinates.

  In step 204, the difference factor analysis unit 112 analyzes the difference factor and registers the analysis result in the difference factor analysis result 116. FIG. 10 shows an example of the difference factor analysis result 116. The difference factor analysis result 116 stores a difference ID 1001, a form name 1002, a factor candidate form name 1003, a change ID 1004, an operation content 1005, and a change requirement 1006.

  First, the difference factor analysis unit 112 extracts a candidate form of the factor for each extracted difference from the new and old form difference results 115 and the format definition coordinates 107. Specifically, the difference coordinates 903 and the form coordinates 704 of each form are compared, and the form in which the overlapping area exists becomes the factor candidate form name 1003. In FIG. 10, since the difference coordinates of the difference with the difference ID = 1 are (30, 20, 50, 30), Form B and Form C including the area are extracted as the factor candidate form names. Similarly, form B and form F are extracted as the cause candidate form names with difference ID = 2, and form name B and form H are extracted as the cause candidate form names with difference ID = 3.

  Next, the difference factor analysis unit 112 acquires the change ID 501, the operation content 504, and the change requirement 505 from the format change log 105 using the factor candidate form name as a key, and obtains the change ID 1004, the operation content 1005, and the change requirement 1006. sign up. For example, when the difference ID = 1, change IDs = 1, 2, and 3 corresponding to the form C are acquired and registered in the difference factor analysis result 116. On the other hand, when the difference ID = 3, since there is no change ID corresponding to the form H, “-” indicating no corresponding is registered.

  In step 205, the worker makes an inquiry about the difference between the old and new forms in the difference factor display unit 113 and displays the result to the worker. A display example is shown in FIG. In FIG. 11, the form name 1101 being compared, the comparison result 1102 comparing the forms generated by the old and new systems, the difference ID list 1103 that is a list of the places where the difference has occurred, and the cause of the difference for each difference ID. It consists of a factor analysis 1104 for each difference ID that displays a list of possible change operations. The difference factor display unit 113 displays the comparison result 1102 and the difference ID list 1103 based on the form name selected by the operator. Next, the worker selects a difference ID from the difference ID list 1103 and the difference result 1102, and the difference factor display unit 113 displays the change work related to the selected difference ID in the factor analysis 1104 for each difference ID.

  Regarding the comparison result 1102, there is conventionally a method for comparing two forms generated by the new and old systems on one screen. For example, to automatically correct misalignment and distortion when scanned with a scanner and detect only the really different parts as differences, and to enclose a place where it is difficult to see the difference with a polygonal frame to make the difference easy to see Etc. However, in the prior art, the operator cannot immediately determine what causes the detected difference has occurred.

  On the other hand, in this embodiment, since the information described in FIG. 10 is held for each difference, the operator can immediately determine the factor by changing the display method for each factor of the detected difference. It becomes possible. For example, in FIG. 11, a portion where a difference has occurred even though the operator has not changed the format definition is displayed in a red frame, and a portion where the difference has not occurred is displayed in a blue frame. As a result, it is possible to graphically determine whether the cause of the difference is a specification generated due to a change in the format definition, or a bug in the system program or a bug caused by forgetting to set the format definition.

  Further, by applying this embodiment, it is possible to display only a portion related to the format definition changed according to a certain policy as a difference result and confirm whether the policy is satisfactory. In the following, an example is described in which a policy has been set in which characters that have been displayed in the Gothic font until now are in the Mincho style. The worker selects the attribute value of the form name 1002, the operation content 1005, and the change requirement 1006, and makes an inquiry to the difference factor display unit 113. In this example, the value of the operation content 1005 is “font (Mincho)” and an inquiry is made. The difference factor display unit 113 retrieves the operation content 1005 of the difference factor analysis result 116, extracts a form whose font is changed to Mincho and a factor candidate form name, and displays only the form in a polygon frame and displays it on the screen. To do. As a result, only the difference corresponding to the policy can be graphically displayed, so that the operator's judgment becomes easy.

  In the present embodiment, it is assumed that the format change log 105 exists. Even when the format change log 105 does not exist, a form that affects the generated difference can be graphically displayed to the operator. Thereby, the difference factor analysis work can be reduced.
