JP5715219B2 - Form processing system, server, program, and form processing method - Google Patents

Description

  The present invention relates to a form processing system, a server, a program, and a form processing method that are installed in a financial institution and transmit form image data and character data to an operator's terminal that processes forms such as an account opening request form.

  In a conventional form processing system, a server apparatus manages form data such as image data obtained by scanning a form of a customer and character data obtained by OCR (Optical Character Recognition) processing, from the server apparatus to an operator terminal. By transmitting the form data, the operator can confirm the contents of the form and correct the contents.

  At this time, the form data to be subjected to work requiring high level confirmation such as seal verification and correction of input contents is transmitted to an operator terminal operated by an operator with a high skill level (for example, Patent Document 1).

JP 2006-146830 A (paragraph “0033” -paragraph “0034”, FIG. 1)

  However, in the conventional technology described above, the characters themselves described in the form are not considered. That is, the character data obtained by the OCR process may include characters that have been erroneously recognized from the characters described in the original image data. In addition, a form including many similar characters that are easily misrecognized is more important for the operator in the confirmation operation than a form having few similar characters, and the degree of processing becomes high. However, in the conventional method, since some degree of similar characters is not considered as being irrelevant to the difficulty of work, there are many similar characters at random for both low-level and high-level operators ( The data of a form (high difficulty) and a form with few similar characters (low difficulty) were sent for confirmation. In this case, there is little problem if an operator with a high level of proficiency is responsible for the data of the form with high difficulty, but it is unfamiliar when an operator with a low proficiency level is in charge of the form with high degree of difficulty. However, there is a problem that the possibility of an artificial error of failing to correct similar characters that have been misrecognized increases.

  An object of the present invention is to provide means for solving the above problems.

To solve the above problems, the present invention compares a form image data with character data obtained by character recognition of the image data, and a form processing system in which an operator performs an operation of correcting or confirming character data. In this case, a character having a similar shape is defined in advance as a similar character, and whether the number of the similar characters among the characters included in the character data of the form is large or small with respect to the character recognition result of the form. Based on the information shown and information on the proficiency level of the operator's work, an operator with a high proficiency level is in charge of a form with a lot of similar characters, and an operator with a low proficiency level is in charge of a form with few similar characters As described above, the operator in charge of the form is determined, and the character data of the form is corrected or confirmed.

  As a result, the present invention can select operators according to information on the number of similar characters and process the form, thereby reducing the occurrence of human error such as processing similar characters by mistake. The effect of being able to be obtained.

  The operation of the above-described configuration will be described according to the steps indicated by S using the flowchart showing the form scanning process shown in FIG.

  The clerk places the form deposited from the customer on the form inhalation unit of the scanner device 7 of the image reading apparatus 1 and performs input for reading image data by the input unit 3.

  S1, when the control unit 5 of the image reading apparatus 1 recognizes that an input for reading image data has been made, the control unit 5 conveys the form placed on the form inhaling part (not shown) and reads the image data by the scanner unit 7. The image data is stored in the storage unit 6.

  S <b> 2, the control unit 5 converts the image data read from the form into character data by the character recognition means, and stores the character data in the storage unit 6.

  S3, the control unit 5 refers to a table of similar characters stored in the storage unit 6 and counts the number of similar characters included in the character data converted from the image data.

  S4, the control unit 5 counts the total number of characters included in the character data, uses the total number of characters and the number of similar characters counted in step S3, calculates the similar character rate by the similar character rate calculation means, The similar character rate is stored in the storage unit 6.

  S5, the control unit 5 assigns the sequence number, reads out the stored image data, character data, and the similar character rate, and forms the form data configured by associating the sequence number, the image data, the character data, and the similar character rate. The data is transmitted to the form DB server 8 via the communication line 9.

  S6, the form DB server 8 stores the received form data, updates the form data table based on the contents of the form data, and ends the form scanning process.

  Next, a form content confirmation process for allowing the operator to confirm the description contents of the form will be described according to the steps indicated by SA using the flowchart showing the procedure of the form content confirmation process shown in FIG.

  Here, it is assumed that the operator performs an input operation for requesting confirmation data by the terminal input unit 12 of the operator terminal 10 in order to confirm the description content of the form.

  SA1, when the terminal control unit 14 of the operator terminal 10 recognizes that an input operation for requesting confirmation data by the operator's terminal input unit 12 has been performed, reads the operator ID stored in the terminal storage unit 13, and the operator A data request message with an ID is transmitted to the form DB server 8 via the communication line 9.

  SA2, the server control unit 8a of the form DB server 8 refers to the operator table stored in the server storage unit 8b based on the operator ID of the received data request message, and identifies the corresponding operator rank.

  In step SA3, the server control unit 8a extracts form data including image data and character data to be transmitted to the operator terminal 10 according to the operator rank specified above, in which no input data is input from the form data table.

  Here, FIG. 7 is an explanatory diagram showing the flow until the form data is extracted from the form data table. (A) is a state in which the form data is arranged in the sequence number order, and (b) is the form data in the order of the similar character ratio. Indicates the state of arrangement.

That is, in the similar character order shown in FIG. 7B, the form data of sequence number 3 having the largest similar character rate of 17% is extracted.

  When the operator rank is B, in the form data table, the form data in the middle when the form data is arranged in the order of similar character ratio is extracted, that is, the order in the similar character order shown in FIG. The form data of sequence number 5 in the middle is extracted.

  Further, when the operator rank is C, the form data with the smallest similar character rate is extracted, that is, the form with the sequence number 4 having the smallest similar character rate of 1% in the similar character order shown in FIG. Extract data.

  Needless to say, if there is only one form data that can be extracted from the form data table, the remaining form data is extracted.

  SA4, the server control unit 8a reads the image data, the character data, and the sequence number from the extracted form data, associates the read image data with the character data, and the sequence number as confirmation data, and uses the confirmation data via the communication line 9. To the operator terminal 10.

  SA5, the terminal control unit 14 of the operator terminal 10 stores the sequence number of the received confirmation data in the terminal storage unit 13 and displays the image data and character data of the confirmation data on the terminal display unit 11 as well as the image data. The user confirms the contents described in the form by the above, and displays a confirmation instruction screen for confirming the misrecognized characters and the description contents in the character data and prompting the correction.

  As a result, the operator compares the image data with the character data, confirms the character data based on the description on the form, and if there is a misrecognized character in the character data, corrects the input. Do.

  SA 6, the terminal control unit 14 reads the stored sequence number, uses the character data that has been corrected and input as input data, attaches the sequence number to the input data, and transmits it to the form DB server 8 via the communication line 9.

  SA7, the server control unit 8a of the form DB server 8 reads the stored form data based on the received sequence number, adds the received input data to the form data, and updates the contents of the form data table. The form content confirmation process is terminated.

  Thus, the present invention allows an operator with a high level of proficiency to process a form with many similar characters and an operator with a low proficiency level to process a form with few similar characters. It is possible to reduce the occurrence of human error in processing.

  As described above, in this embodiment, when the operator confirms and corrects the character data converted from the image data of the form by the character recognition unit, the ratio of similar characters included in the character data is calculated and the similarity is calculated. The character rate is included in the form data and stored, and when sending image data and character data to the operator terminal, the form data with a high rate of similar character rate is given to operators who are skilled from the skill level of the operator. Image data and character data were sent, and image data and character data of form data with a small percentage of similar character ratio were sent to an inexperienced operator, so it was misrecognized when converted from image data to character data The possibility of human error such as missing correction of similar characters can be reduced.
