  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a configuration of a document management system according to the present embodiment. The document management system 300 includes a scanner 200 and a document management terminal 100 (information processing apparatus).

  The scanner 200 has an image scanning unit 20. The document management terminal 100 includes a character recognition unit 1 (recognition unit), a character editing unit 2 (editing support unit), an output unit 3 (display unit), and an old and new comparison table generation unit 4 (contrast table generation unit).

  The document management terminal 100 includes a CPU (Central Processing Unit) that is an arithmetic processing device, a memory that is a main storage device, a nonvolatile storage device (flash memory, a hard disk drive, etc.), a keyboard, a mouse, a display, a printer, and the like. The computer having the input / output device. Each functional block in the document management terminal 100 is realized by loading a document management program stored in advance in a non-volatile storage device onto the memory and calculating and executing the document management program by the CPU.

Next, a detailed description of each of these functional blocks will be given.
Details of the image scanning unit 20 will be described with reference to FIG. The image scanning unit 20 irradiates light to an uncorrected original 51 (at least one character or a plurality of characters written on the uncorrected original 51) managed by a paper medium, and digitally uses the reflected light. Image data 52 is generated by converting the data. The generated image data 52 is transmitted to the character recognition unit 1 of the document management terminal 100.

  Details of the character recognition unit 1 will be described with reference to FIG. The character recognizing unit 1 analyzes the image data 52 transmitted from the image scanning unit 20 and converts a portion that seems to be a character string into text data (data constituted by a predetermined character code). Coordinate information indicating where the image data 52 exists is added to the converted text data in units of lines.

  Further, the character recognition unit 1 associates the text data with the image data 52 by assigning the file name of the image data 52 and the location where the image data 52 exists (in which folder) to the converted text data. I do. This text data is generated as text data 53 in the XML format. When the process is completed, the character recognition unit 1 stores the generated text data 53 and the image data 52 used for recognition as a file in a predetermined storage location.

  Here, an example of the text data 53 generated by the character recognition unit 1 is shown in FIG. As shown in FIG. 4, by setting the information (image data information) of the image data 52 on the text data 53, the image data 52 and the text data 53 are matched during the merge process by the output unit 3. In the text data 53 shown in FIG. 4, the image data information from “<image path> /usr/DAT/A00001/genpon.jpg </>” to “<image height> 296.7 </>” Each value of “xs”, “ys”, “xe”, and “ye” is coordinate information for each row with the upper left corner of the image data 52 as a reference.

  Details of the character editing unit 2 will be described with reference to FIG. The character editing unit 2 supports the editing work by the editor by calling the text data 53 generated by the character recognition unit 1 and displaying the character string on its own editor. The editing result is written to the text data 53 again. The data displayed by the editor of the character editing unit 2 is in a state in which no XML tag, image data information, or coordinate information is attached (that is, text data immediately after being recognized by the character recognition unit 1). Shall.

  The character editing unit 2 calls the stored text data 53 and passes it to the editor (step S1). The editor displays the passed text data 53 on the screen of the input / output device (for example, display), and the editor performs editing work using the keyboard and mouse on the screen (S2). During the editing work in the editor, the text data loaded in the memory is corrected.

  At the timing when the editor instructs to save the editing result, the editor compares the text data after editing loaded in the memory with the text data 53 before editing, and the correction information tag (described later) together with the text information before and after editing. ) Is newly created as text data 53 (S3). The created text data 53 is written into the nonvolatile storage device. In this embodiment, the text data before editing is overwritten and saved with the text data after editing. However, the text data may be saved in separate files.

  An example of a method for setting the correction information tag by the character editing unit 2 is shown in FIG. In the present embodiment, the correction information tag is an <ins /> tag (hereinafter referred to as an insertion tag (insertion information)) indicating an inserted character string, and a deleted character string. <Del /> tag (hereinafter referred to as deletion tag (deletion information)). All edit results of text data can be expressed by “insertion” and “deletion”. The replacement of a character string can be expressed by a combination of “delete” and “insert”. The character editing unit 2 sets a correction information tag in the text data 53 in the XML format when writing the result edited on the editor to a file.

  As in the example of FIG. 6, when the user modifies the character string “Today's weather was rainy but sunny from the afternoon” to “Today's weather was sunny” (FIG. 6 (A )), The character editing unit 2 assigns an insertion tag to the inserted character string, and creates text data 53 to which the deleted character string is assigned a deletion tag instead of actually deleting data. (See FIG. 6B).

  Next, the detail of the output part 3 is demonstrated based on FIG. Upon receiving an instruction to output correction confirmation data from the character editing unit 2 (step S10), the output unit 3 captures the edited text data 53 and image data 52 stored as files in the nonvolatile storage device. (S11, S12), the correction confirmation data 54 obtained by merging them is generated (S13), and output as a file to the nonvolatile storage device or displayed on the input / output device (for example, display) (S14).

  An example of the layout of the correction confirmation data 54 is shown in FIG. The correction confirmation data 54 has a data structure having at least layout information that defines where image data and character strings are to be arranged. In the present embodiment, the correction confirmation data 54 is divided into an area where the image data 52 is arranged (image data arrangement area) and an area where the inserted character string is arranged (correction information arrangement area). Data in a format displayed on an input / output device (for example, a display). The image data 52 is arranged by reducing the data stored in the file as necessary.

  With reference to FIG. 9, a merge process (a method for creating the correction confirmation data 54) by the output unit 3 will be described. The output unit 3 arranges the image data 52 in the image data arrangement area of the correction confirmation data 54, and calculates which character string of the image data 52 has been deleted from the correction information tag and the coordinate information in the text data 53. Then, attention information (shading of the deleted part) that allows the confirmer to visually recognize the correction contents is put on the corresponding character string. Further, the output unit 3 arranges a balloon pointing to the insertion position in the image data 52 in the correction information arrangement area, and sets an insertion character string in the balloon. In the example of FIG. 9, the output unit 3 places shaded attention information on a character string with a deletion tag attached to the image data 52, and places a balloon that points to the insertion position of the image data 52 in the correction information arrangement area. Then, the character string to which the insertion tag is attached is placed in the balloon. A more specific example of the correction confirmation data 54 is shown in FIG.

  The operation of the merge process by the output unit 3 will be described with reference to the flowchart of FIG.

  The output unit 3 receives the text data 53 from the nonvolatile storage device (S20), and receives the image data 52 from the nonvolatile storage device (S21). The output unit 3 arranges the image data 52 in the image data arrangement area shown in FIG. 8 (S22), and reads the text data 53 (S23).

  Here, the output unit 3 determines whether or not the text data 53 has been read to the end (S24), and if it has not been read to the end (S24, NO), determines whether or not the current read location is a correction information tag. (S25). If it is not a correction information tag (S25, NO), the process returns to step S23 to read the next character in the text data 53. On the other hand, when it is a correction information tag (S25, YES), the output unit 3 determines the type of the correction information tag (S26).

  When the correction information tag is a deletion tag (S26, deletion tag), the output unit 3 calculates a deletion range (S27). In the present embodiment, the output unit 3 determines the number of characters (value A) from the end of the line where the first character of the character string to which the deletion tag of the text data 53 is assigned, and the deletion tag. Is counted to determine the deletion range.

The output unit 3 sets a deletion location on the image data 52 and puts attention information on the corresponding location (S28). The output unit 3 executes the following process in step S28.
(S28-1) The coordinate information (coordinates of the starting point (xs, ys) and ending point (xe, ye) of the line) of the line in which the character string to which the deletion tag is assigned is acquired from the text data 53.
(S28-2) The corresponding line of the image data 52 is specified using the acquired coordinate information.
(S28-3) On the image data 52, the size in the character direction of the coordinate information is divided by the total number of characters before correction (value C) of the identified line (in the case of horizontal writing: (xe−xs) / C, In the case of vertical writing: (ye−ys) / C) The coordinate position for each character is calculated, and the range of the coordinate position corresponding to the value B is shaded from the coordinate position corresponding to the value A.
In S27, in order to prevent a shift between the count value of the text data 53 and the coordinate position to be shaded in S28-3, the character string to which the XML format tag character and the insertion tag are attached is counted. Shall not.

  In step S28, in addition to the above method, after a line is specified in the image data 52, a character string to which a deletion tag is attached is acquired, and the corresponding line in the image data 52 is deleted using the OCR function. A method of searching for whether or not a character string has a tag is also conceivable. However, when there are a plurality of the same character strings in the same line of the image data 52, one of them is assigned a deletion tag, and the other is not attached, a search target character string is found by searching the image data 52. Sometimes, it is difficult to determine whether the character string is to be deleted. In the present embodiment, the above-described mounting is performed in consideration of such points.

  The description returns to the process of step S26. When the correction information tag is an insertion tag (S26, insertion tag), the output unit 3 calculates the insertion location (S29). The output unit 3 counts the number of characters from the end of the line where the character immediately before the character string to which the insertion tag of the text data 53 is assigned.

  Next, the output unit 3 extracts the character string to which the insertion tag is assigned from the text data 53 (S30), and sets the insertion location in the image data 52 (S31).

The output unit 3 executes the following process in S31.
(S31-1) The coordinate information (coordinates of the start point and end point of the line) of the line in which the character string to which the insertion tag is attached is obtained from the text data 53.
(S31-2) The corresponding line of the image data 52 is specified using the acquired coordinate information.
(S31-3) On the image data 52, the size in the character direction of the coordinate information is divided by the total number of characters before correction (value D) in the specified line (in the case of horizontal writing: (xe−xs) / D, For vertical writing: (ye−ys) / D) When the coordinate position for each character is calculated in order from the base point of the line, and the number of calculated coordinate positions becomes the count value obtained in step S29, A coordinate position is specified as an insertion location on the image data 52.
In S29, in order to prevent a shift between the count value of the text data 53 and the coordinate position of S31-3, the character string to which the XML format tag character and the insertion tag are attached is not counted. .

  Next, the output unit 3 arranges a balloon that points to the insertion location on the image data 52 obtained in step S31 in the correction information arrangement area (see FIG. 8), and an insertion tag is assigned to the area in the balloon. Place the character string. (S32).

  After step S28 and step S32, the process returns to S23, and the process for the next character is executed. If the output unit 3 determines in step S24 that the text data 53 has been read to the end (YES in S24), the output unit 3 creates a file of the correction confirmation data 54, displays it on the display, and releases the used memory. Etc.) is executed (S33), and the process ends.

  Next, details of the new and old comparison table generator 4 will be described with reference to FIG. The old and new comparison table generation unit 4 receives an instruction to output the old and new comparison table from the character editing unit 2 (S40), takes in the text data 53 generated by the character editing unit 2 (S41), and corrects information in the text data 53 The new and old comparison table 55 is generated based on the tag and output as a file (S42, S43). The data output as the old and new comparison table 55 is assumed to be in CSV (Comma Separated Values) format.

  A generation example of the old and new comparison table 55 is shown in FIG. The old and new comparison table generation unit 4 extracts character string information in line units from the text data 53, and generates the old and new comparison table 55 before and after correction according to “insertion” and “deletion”. In the present embodiment, as in the example of FIG. 13, “page” indicating the page number, “number of lines” indicating the number of lines before correction, “modification type” indicating (insertion / deletion) or deletion, CSV data is generated with “record before modification” indicating a character string before correction and “after correction” indicating a character string after correction as one record. The text data from which the character string with the insertion tag is removed is extracted in the “original document”, and the text data from which the character string to which the deletion tag is added is removed in “After modification”. Extracted.

  Here, the reason for creating the old and new comparison table will be described. For example, after a document is corrected, a notification document for notifying the correction content may be created. This notification document must describe which part of the document has been modified and how. Conventionally, a notification document has been created by visually checking the correction location, but if the device automatically creates a new and old comparison table as in this embodiment, the notification document can be created by pasting the created table as it is. Can be created. Therefore, working efficiency can be improved by this embodiment.

  For example, when a document correction is instructed by administrative guidance from an organization such as a supervisory government office, it is necessary to report the correction result to the organization. It is possible to use the old and new comparison tables for the correction contents described in this report document.

  Finally, the overall operation of the document management system 300 will be described with reference to the flowchart of FIG.

  The image scanning unit 20 reads the uncorrected original 51 and generates image data 52 (for example, image data in JPEG format) (S51). It is assumed that the image data 52 includes a character string composed of at least one character or a plurality of characters.

  The character recognition unit 1 reads a character string from the image data 52 and generates text data 53 (S52). The text data 53 is given coordinate information indicating the position of the line in the image data 52 for each line of the character string written in the image data 52.

  The character editing unit 2 acquires the text data 53 generated by the character recognition unit 1, adds a deletion tag to the deleted character string, and inserts it according to the editing operation by the user on the text data 53. An insertion tag is assigned to the character string that has been set. The character editing unit 2 generates text data 53 to which these deletion tags and insertion tags are assigned (S53).

  Next, a description will be given of processing when there is an instruction to output correction confirmation data from the character editing unit 2 (S54, correction confirmation data).

  The output unit 3 creates correction confirmation data and displays it on a file output or display (S55). S55 will be described. The output unit 3 acquires the image data 52 and the text data 53 generated by the character editing unit 2. The output unit 3 displays the image data 52 and the character string to which the insertion tag is attached. Further, the output unit 3 displays the character string of the image data 52 corresponding to the character string to which the deletion tag is assigned in a format different from other character strings (for example, a shaded format). In addition, the output unit 3 displays in which format the character string to which the insertion tag is added is inserted into the image data 52 in a format that the user can visually recognize (for example, a balloon pointing to the insertion location).

  A description will be given of how to specify a deletion location and an insertion location on the image data 52. The output unit 3 uses the text data 53 generated by the character editing unit 2 to determine the number of characters from the end of the line, and the number of characters in the character string, to which the first character of the character string to which the deletion tag is assigned. The character string of the image data 52 corresponding to the character string to which the deletion tag is assigned is specified based on the count value and the coordinate information. In addition, the number of characters from the end of the line at which the first character of the character string to which the insertion tag is attached is counted using the text data 53 generated by the character editing unit 2, and this count value and Based on the coordinate information, it is specified in which of the image data 52 the character string to which the insertion tag is attached is inserted.

  The description returns to the determination process of S54. The processing when the character editing unit 2 instructs to output the old and new correspondence table (S54, old and new correspondence table) will be described.

  The old and new comparison table generation unit 4 identifies a character string deleted or inserted by a user editing operation based on the deletion tag and insertion tag of the text data 53 generated by the character editing unit 2, and the editing operation The old and new comparison table 55 before and after is generated (S56).

  In the present embodiment, the document management terminal 100 acquires image data and processes the image data. However, the present embodiment is not limited to image data, and any data having a character string can be applied. can do.

  In the present embodiment, the document management system 300 divided into two units of the scanner 200 and the document management terminal 100 has been described. However, these two units are assumed to be one OCR device (optical character reader). Is also possible.

  As in this embodiment, by merging the confirmation work of the uncorrected original and the corrected output into a single image, it becomes possible to clearly indicate the correction location for the uncorrected original, and omission of confirmation This makes it easier to confirm the comparison. In addition, by creating a table in which the text information of the original before correction and the text information after correction are compared, it is possible to easily create a comparison between old and new.

  In the present embodiment, the document management program is described as being installed in advance in the above-described document management terminal. However, the document management program in the present invention includes one stored in a storage medium. Here, the storage medium is a medium that is detachable from the document management terminal, such as a magnetic tape, a magnetic disk (hard disk drive, etc.), an optical disk (CD-ROM, DVD disk, etc.), a magneto-optical disk (MO, etc.), and a flash memory. Further, it refers to all media that can be read and executed by a computer in the document management terminal described above, such as media that can be transmitted via a network.
