Description

  The present invention deals with various handwritten forms (original documents) such as a written list, a medical certificate, an account transfer request document, an invoice, an invoice, or a list on which various personal information is described, which is handled by an individual or a corporation. When converting so that it can be handled as computerized information that can be handled by a terminal device such as a computer, whether or not the handwritten form and the digitized (text) information have the same content (whether there is a difference) A document data verification method for improving the accuracy and processing speed of the verification, and stabilizing the processing speed, and a document data verification support system for supporting verification work by using the method, It is about.

  For example, a form containing various handwritten original forms such as a written statement, a medical certificate, an account transfer request form, an invoice, an invoice, or a list containing various personal information (hereinafter referred to as a handwritten document) As a method of digitizing (data) so that it can be handled by a terminal device such as a computer, for example, the information of the handwritten document data is displayed as an image using a reading means such as a scanner (document before processing). A method of text conversion (conversion processing using OCR) that identifies characters from the displayed image and converts them into a document, or a character input worker (input person) or the like There is a method of inputting a document based on the information while confirming information described in the handwritten document data using an input terminal device.

  Conventionally, as a technique for converting the information of such handwritten document data into text, for example, the input requester side divides image data of the entire handwritten or printed document into a plurality of partial image information on the image. In this case, users who want to perform input work using the Internet after performing fragmentation until it becomes impossible to derive meaningful information from the fragmented single partial image information itself Is an information input system for inputting text of the partial image information from a terminal, and the partial image information fragmented until it is impossible to derive the meaningful information on the Internet. Means for individually publishing, until it is impossible for the user to derive the meaningful information published on the Internet From among the fragmented image parts information, as input freely selected individually, it is the information input system according to claim (see Patent Document 1).

  In a document obtained by converting handwritten document data into text using such a method (hereinafter referred to as processed document data), the handwritten document data (or preprocessed document data) and the information of the processed document data are completely Although they preferably match, there may be a difference in information between the handwritten document data and the post-processed document data due to the accuracy of OCR, input mistakes by the person in charge of input, or the like.

  Therefore, by verifying whether or not there is a difference between the handwritten document data and the processed document data, correctness of information in the processed document data is determined, and information between the handwritten document data and the processed document data is determined. Are required to match completely.

  As a method for reducing the occurrence of such difference between two document data and maintaining and improving the accuracy of post-processed document data information such as input data, for example, a first input person and a second input person There are a verification method in which an operator performs input work twice, and a third-party verification method in which a difference portion (unmatch portion) is compared and verified by a third party after a match (compare), and the difference portion is corrected.

  In this verification method, since the verification work for judging and confirming the input contents is entrusted to the input person who inputs the second time, depending on the skill and judgment level of the input person who inputs the second time, There is a problem that an error in accuracy may occur.

  On the other hand, the third-party verification method is a method in which verification is performed by a third party after comparison. Since this third party (verification person) is in charge of a person different from the input person, Since the verification work is performed by comparing information between the handwritten document data or the pre-processing document data and the post-processing document data from a different viewpoint, the accuracy of the verification work may be improved as compared with the verification method. Be expected.

  Conventionally, as this kind of verification method, a verification work support system for supporting verification work for verifying one or more design data using one or more test cases using a simulator, the test case Basic information input means for receiving input of basic information necessary to specify the template, template file generation means for generating a template file including the basic information input by the basic information input means, and items other than the test case Individual information input means for receiving input of individual information necessary for identification, and the verification operation by reading the basic information from the template file and adding the individual information input by the individual information input means to the basic information Parameter file generating means for generating a parameter file necessary for There is a verification work support system (see Patent Document 2) characterized by comprising verification work execution means for executing the verification work while activating the simulator in accordance with a file. Document 3 or Patent Document 4 is available.

  However, the third-party verification method is expected to perform verification work with higher accuracy than the verification method as described above. However, in the actual on-site work, the person in charge of the verification uses the handwritten document data or the verification terminal device. When verifying by comparing only the image information of the pre-processed document data and the post-processed document data to be displayed, that is, when the input specifications are compared and judged / confirmed only by information obtained visually, the verification method is used. There is a case where there is not much difference in accuracy even when compared with the above, and there is a possibility that the same problem as the verify method may occur.

  In addition, these verification operations may involve hundreds to thousands of operations per day. If the verification person continuously performs such a large number of verification operations, Since the work is monotonous, the willingness of the person in charge of verification tends to decrease with time, the number of verifications per unit time (processing speed) tends to decrease, and the accuracy of verification (quality) It can also be difficult to maintain.

  As described above, since the verification work ultimately has to rely on human confirmation work, it is difficult to improve the accuracy by visual verification work alone.

  Therefore, there is a problem to be solved by further improving the accuracy of verification and stabilizing the processing speed of verification.

  As specific means for solving the problems of the conventional example described above, as the first invention according to the present invention, the information described in each of the two document data is compared using a verification terminal device. A document data verification method that enables verification of the presence / absence of a difference in the image data, wherein the two document data include an image of pre-processed document data that is an image display of handwritten document data information, and A text conversion process for identifying a character and converting it into a document, or an image of post-process document data in which a document is input using an input terminal device based on the handwritten document data. A process for comparing the image of the post-document data with a process for reading out and comparing the information of the post-process document data by voice and verifying them simultaneously. There is provided a document data verification method according to claim.

  In addition, as a second invention, by comparing information described in each of two document data using a verification terminal device, it is possible to verify whether there is a difference in the document data. In this case, the two document data are converted into a document by identifying an image of pre-processed document data, which is an image obtained by displaying handwritten document data information, and characters from the image. And the processed document data image obtained by inputting the document using the input terminal device based on the handwritten document data, and the comparison using the verification terminal device is the image of the unprocessed document data. And the comparison of the processed document data with the image and the comparison by reading aloud the information of the processed document data by voice are simultaneously processed. There is provided a document data verification support system characterized by verifying by.

  In the second aspect of the invention, the comparing means using the image-displayed image displays a marker on the read-out portion of the image-displayed image in synchronism with the timing when the information of the document data is read out by the comparing means based on the reading aloud; The constant speed can be varied and adjusted in advance; the verification terminal device is connected to a data management server that manages the document data via a network, and the data management server It is included as an additional requirement that a verification operation can be performed by a plurality of verification terminal devices to be connected.

  In the document data verification method and the document data verification support system according to the present invention, by comparing the information described in each of the two document data using the verification terminal device, whether or not there is a difference between the document data A document data verification support system for supporting verification work, wherein the two document data include an image of pre-processed document data that is an image of information on handwritten document data, A text conversion process for identifying characters from an image and converting them into a document, or an image of processed document data obtained by inputting a document using an input terminal device based on the handwritten document data, and using the verification terminal device The comparison is made by comparing the image of the pre-processed document data with the image of the post-processed document data, and the information of the post-processed document data by voice Because it is a configuration that verifies by performing simultaneous processing together with comparison by reading aloud, the auditory information that is automatically read out at a constant speed (constant rhythm) that can be varied by the terminal device for verification, Since it has a pacemaker-like action, the verification processing speed is stabilized, and verification work can be performed using two types of information, visual information and auditory information. There is an excellent effect that the accuracy of verification can be improved as compared with the case of performing verification work.

Next, the present invention will be described in detail based on specific embodiments.
A document data verification method and a document data verification support system according to the present invention will be described with reference to FIGS. FIG. 1 shows a schematic diagram of an example of a network configuration for constructing a document data verification support system according to the present invention. In the case of performing verification work using the document data verification support system, it is preferable to use a network so that a plurality of persons in charge of verification can perform verification. The network does not necessarily have to be used, and only one or more independent verification terminal devices may be used.

  The network 1 includes, for example, a data management server 2, a voice recognition server 3, and a verification terminal device 4, which are connected in a communicable state. Note that the voice recognition server 3 does not necessarily have to be provided as an independent server. For example, the data management server 2 or the verification terminal device 4 may be configured to also function as the voice recognition server 3.

  Although not shown in the drawing, a plurality of input terminal devices are connected to the data management server 2, and various data input or created by the input terminal device are stored in the data management server 2, The data can be used by the input terminal device or the verification terminal device 4 connected to the data management server 2.

  In the input terminal device, the person in charge of input directly inputs or converts the handwritten document data into text by OCR conversion processing, that is, conversion processing to electronic information that can be used in a terminal device including the verification terminal device 4. To create post-processed document data. The input terminal device and the verification terminal device 4 may be shared.

  The storage device of the data management server 2 captures the processed document data and the original data of the processed document data, and the handwritten document data into the terminal device using reading means such as a scanner. Pre-processing document data that is image displayable data is stored, and these two document data are displayed on the display screen of the verification terminal device 4 when the verification operation is performed using the verification terminal device 4, for example, The image is displayed at the same time by dividing the screen horizontally.

  The speech recognition server 3 reads the processed document data stored in the data management server 2 and then uses a predetermined speech conversion program that can convert text information included in the processed document data into speech information. The processed document data is converted into audio information, and the converted audio information is stored.

  Next, the flow of processing when using the document data verification support system will be described with reference to the flowchart of FIG. First, handwritten document data to be verified is prepared as f1, the handwritten document data is captured so that it can be handled by an input terminal device using a reading unit such as a scanner, and processed before image processing is image data of handwritten document data. Create document data f2.

  Then, using the input terminal device, the image data of the handwritten document data (preprocessed document data) is subjected to OCR conversion processing, or the person in charge of input uses the input means such as a keyboard to obtain information on the handwritten document data. Is directly input to create post-processed document data f3.

  These pre-processed document data and post-processed document data are stored in the data management server 2 and are managed so as to be readable by a predetermined verification terminal device 4 connected to the data management server 2 over the network. That is, the verification work can be simultaneously performed by any and a plurality of verification terminal devices 4 connected to the data management server 2 via the network.

  In the data management server 2, optionally, a process f5 for extracting the data of the difference part of the text character in the two document data from the information of the stored pre-process document data and post-process document data, for example, different A process f6 of performing an OCR conversion process using a plurality of programs and extracting the data of the difference part, etc., and storing the extracted data of the difference part in the data management server 2 may be performed. In this case, it is possible to reduce the number of items / parts to be verified later by the person in charge of verification, and to facilitate the verification work.

  In the speech recognition server 3, the post-processed document data stored in the data management server 2 (or the difference part data, which is the same as the process of the post-processed document data, and hence the description of the difference part data is omitted). , The processed document data is converted into voice information (voice synthesis process) by using a predetermined voice conversion program that can convert the text information of the processed document data into voice information f7. In the voice conversion program, for example, all the kanji characters included in the processed document data are converted into either reading (onyomi) or kanji reading, or reading kanji candidates. The conversion method can be set. Further, in order to further improve the accuracy of verification, it may be possible to perform settings such as reading aloud once and then reading again.

  The verification terminal device 4 reads the information of the pre-processing document data and the post-processing document data to be verified from the data management server 2 and displays the display screen of the verification terminal device 4 as shown in FIGS. The image image 6 of the pre-processed document data is displayed on the right side, and the image image 7 of the post-processed document data is displayed on the left side. At this time, the verification terminal device 4 reads the voice information corresponding to the processed document data from the voice recognition server 3 so that the voice information can be used when the two document data are verified.

  The person in charge of the verification stores information described in each of the two document data images, that is, the image image 6 of the pre-processing document data and the image image 7 of the post-processing document data displayed on the display screen of the verification terminal device 4. Comparison / confirmation by visual inspection is performed to verify whether there is a difference between the two document data (comparison using an image displayed). At this time, sound from headphones or speakers connected to the verification terminal device 4 is used. From the output means, voice information corresponding to the processed document data is read out, that is, the information of the processed document data is read aloud by voice and displayed on the display screen of the verification terminal device 4. The two document data are visually compared and verified, and the pre-processed document data and the process are read out by reading out the information of the processed document data by voice. It become possible to simultaneously process f8 two verification of the method for verifying compares the document data.

  Here, the speed of reading aloud using the verification terminal device 4 can be set after being adjusted and adjusted in advance according to the experience and ability of the person in charge of verification, and automatically at this preset speed. That is, it is automatically read out at a constant speed (a constant rhythm) according to the person in charge of verification.

  If no error is confirmed in the processed document data by the verification f8 in which the visual information and the auditory information are processed at the same time, the processed document data is used as a confirmed final data text file. When an error is confirmed in the processed document data stored in the data management server 2, the erroneous data is corrected f10, and the corrected processed document data is used as the final data text file in the data management server 2 By storing the data, it can be used as data with higher accuracy.

  In this way, verification work with different properties of visual information and auditory information can be performed at the same time. The accuracy of verification in a person can be improved, and the auditory information is provided at a constant speed. Therefore, the auditory information has a metronome or pacemaker-like action, and verification work can be performed at a constant speed. That is, the verification processing speed is stabilized. Furthermore, since the information of the processed document data is read aloud by the verification terminal device 4, it is not necessary to increase the number of persons in charge of verification, so that the human cost does not increase.

  Further, when the comparison by the image displayed image and the comparison by the reading aloud are performed, the reading portion of the image displayed image is displayed as a marker in synchronization with the timing of reading the information read aloud, that is, FIG. As shown in FIG. 4, for example, the information of the item “name” in the image (two document data of pre-processing document data and post-processing document data) displayed on the display screen of the verification terminal device 4 is read aloud. For example, when reading aloud, the “name” item, and as shown in FIG. 4, for example, when reading out the information of the “injury name” item aloud, the “injury name” item, for example, These are displayed with markers 6a and 7a such as an enclosing line, a cursor, or an underline to indicate which part on the display screen is the reading-out part.

  In this way, by displaying the read-out portion of the image displayed in synchronism with the reading-out timing of the document data information by the comparison means by reading aloud with the markers 6a and 7a, for example, a verification person with little experience performs verification work. Even in this case, it is possible to improve the accuracy of verification because it is no longer possible to get confused or mistaken about which part of the image data is read out.

  Further, when it is confirmed that the information of the processed document data is correct by the verification work, as shown in FIG. 5, a marker 6b indicating that verification has been completed is displayed for each item in the information of the pre-processed document data. You may make it do.

It is the schematic which shows the case where the document data verification assistance system which concerns on this invention is constructed | assembled using the network. It is a flowchart which shows the processing method of the document data verification assistance system. It is an example of the display screen of the verification terminal device in the document data verification support system, and a marker indicating a reading portion indicates a name item. It is an example of the display screen of the verification terminal device in the document data verification support system, and the marker indicating the read-out portion is in the state pointing to the item of the name of the disease. It is an example of a display screen of a verification terminal device in the document data verification support system, in a state in which a marker indicating verification is displayed.
