Description

The present invention relates to an information processing device and its control method and program.

A document processing workflow that aims to achieve various tasks according to the work procedure for a document is widely used. In particular, the document processing workflow for importing document information written on paper media into a computer system is expanding its application area from general office work to financial industry, distribution industry, medical care, etc. as the accuracy of document recognition technology is improved. In a document processing workflow using a paper document, it is necessary to automatically recognize the description contents and extract information necessary for business execution. If there is an error in the extracted information, the work will not be achieved or the work efficiency will be significantly reduced. Therefore, it is indispensable to visually check the automatic recognition result and correct any mistake. In order to reduce the burden and time of workers involved in such visual confirmation and correction work, a document workflow system that controls confirmation only when necessary has also been proposed. Patent Document 1 discloses a technique for comparing the similarity and certainty of character recognition results and determining the necessity of manual confirmation. Further, in the case of automatically processing character recognition or the like, a method has been devised in which vocabulary or the like that actually exists is retained as knowledge data and collated with the knowledge data to improve recognition accuracy. Patent Document 2, which is an automatic recognition system based on such knowledge reference, discloses a method of learning an error correction result by updating knowledge data based on the corrected character recognition result.

Japanese Unexamined Patent Publication No. 2003-346080 Japanese Patent No. 2985813

The above-mentioned prior art can determine whether or not the workflow processing result needs to be modified, and can update the knowledge database in order to increase the certainty of the recognition result. However, the knowledge database to be updated as a learning process is defined as a knowledge data update process for identifying recognition candidates. Therefore, it is not mentioned which process must be performed in order to obtain the learning effect in the entire document processing workflow.

An object of the present invention is to enable the next workflow to be executed by referring to the modified workflow processing result in a document processing workflow composed of a complex combination of document processing.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

[First Embodiment]
FIG. 1 is a diagram showing an example of a hardware configuration of a document processing flow control device (information processing device) 100 to which this embodiment is applied. The ROM 102 stores a program to be executed by the CPU 101. The CPU 101 controls the document processing flow control device 100 by executing the control program stored in the ROM 102. By executing this program by the CPU 101, each process shown in the software configuration and the flowchart of the document processing flow control device 100 described later is realized. The RAM 103 temporarily stores various data from each component. The RAM 103 is also used as a storage area for developing a program executed by the CPU 101. The document processing unit 104 performs document processing flow control processing in response to an instruction from the CPU 101. The display unit 105 is composed of a liquid crystal panel or the like, and displays the processing result of the document processing unit 104. The communication unit 106 is a network interface (NIC), and enables communication with other devices on the network via a LAN cable or the like. The bus 107 transmits a digital signal between the devices of the CPU 101 and the communication unit 106 described above.

The CPU 101 of the document processing flow control device 100 having the above components executes each process of the flowchart described later.

FIG. 2 is a functional block configuration diagram of the document processing flow control device 100 when the CPU 101 executes a program stored in the ROM 102. Each of the components 201 to 207 shown in the figure is performed by the CPU 101 that executes the program, but some of them may be realized by hardware.

As shown in FIG. 2, the document processing flow control device 100 includes a job management unit 201, a job input unit 202, a job display unit 203, a job execution unit 204, a job execution result correction unit 205, a correction result reproduction unit 206, and a storage unit. Has 207. The storage unit 207 stores the document processing flow definition document of the document processing flow control device 100, the state of the document processing job, and the input / output information during processing.

The job input unit 202 inputs a flow definition document defining a document processing workflow (hereinafter, also referred to as “document processing flow”) and input data to be processed from an input source (not shown) as a document processing job. It is supplied to the document processing job management unit 201. The input source is not particularly limited, but the data to be processed is explained assuming that the user reads the form through the image scanner and the flow definition document is specified by the user. The job management unit 201 stores and manages the input job. Then, the job management unit 201 controls the execution order of the input jobs, notifies the user of the job execution status by the job display unit 203, and receives instructions from the user to execute the job and confirm the correction. The job execution unit 204 executes document processing according to the execution order of the document processing flow stored in the document processing flow definition document. The job execution result correction unit 205 displays the processing result of the job execution unit 204 on the job display unit 203, receives a user's correction instruction as necessary, and corrects the job execution result. The correction result reproduction unit 206 executes a process of reproducing the correction result by the job execution result correction unit 205 so as to be reproducible.

FIG. 3 is a diagram showing an example of an operation screen of the job list displayed on the display unit 105 by the job display unit 203 in the document processing flow control device 100. In the figure, reference numeral 300 is a window for displaying a document processing job execution control monitor. Reference numeral 301 is a job identification number that identifies a job that is the control target of the job management unit 201. Reference numeral 302 is a job status indicating the execution status of the job identified by the job identification number 301. There are the following types of job status.
-"Waiting for execution" where the input job has not been executed
-"Running", which is being executed by the job execution unit 204 and the processing is not completed.
-"Waiting for confirmation" where the processing flow is completed and the confirmation and correction of the result by the job execution result correction unit 205 is not completed.
-"Complete", which is a state in which the correction confirmation of the job execution result is completed and no correction has occurred.
-The job execution result has been modified, and the process to make the modified result reproducible is being executed. "Reproduction flow is being executed."
-"Playback completed" indicating that playback is possible
By displaying the above types in an identifiable manner, the user can recognize the status of each job.

Reference numeral 303 is an instruction input unit including a stop button 305 for canceling the execution of the job and an execution button 304 for immediately executing the job in the execution waiting state. The user can instruct (click) the instruction input unit with a pointing device such as a mouse (not shown) to execute or cancel the corresponding job. In the case of a job whose job status is "completed" or "reproduction completed", the execution button 304 and the stop button 305 are not displayed on the instruction input unit 303 because the job cannot be executed or canceled. When any one of the job identification numbers 301 is specified by a click operation or the like in the display area, the reference code 306 displays a thumbnail image of the input image in the job. In the illustration, a thumbnail image of the designated job identification number “00182938” is displayed.

FIG. 4 is a diagram showing an example of a flow definition document that specifies a document processing flow definition. The flow definition document is described in XML (eXtensible Markup Language), and <process_flow> is a structured element representing the entire flow definition document. <process> is a structured element that specifies the document processing type to be executed, and the execution order is specified by the orderer attribute. In addition, run-time parameters can be specified in the parameters attribute. In FIG. 4, when the information extension is executed, it is defined to specify three types, patient-id, document-type, and departure-name, which specify extraction information. The document processing type specified by the <process> element is a label corresponding to the document processing service held by the job execution unit 204. The job execution unit 204 executes the document processing service in association with the label indicated by the document processing type.

Hereinafter, document processing flow control based on the document processing flow definition document of FIG. 4 will be described. In this document flow control, patient identification information (patient-id), document type information (document-type), and document belonging clinical department name (department-name) are used from the image of a medical form with a non-standard layout read by an image scanner. Is extracted.

FIG. 9 is a flowchart showing an example of document processing flow execution control in the document processing flow control device. The program related to this flowchart is executed by the CPU 101, and will be described based on the configuration of FIG.

It is assumed that a plurality of document processing jobs have already been input to the storage unit 207 by the job input unit 202 and are managed by the job management unit 201. Further, it is assumed that the job input unit 202 issues a unique job identification number for the form image each time the form image to be processed is input.

In S900, the job management unit 201 acquires an unexecuted job queued in the storage unit 207, and updates the job status of the job from "waiting for execution" to "executing". The job display unit 203 updates the display screen according to the update of the job status. Then, in S910, the job management unit 201 acquires the document processing flow definition document for the acquired unexecuted job from the storage unit 207. Then, the job management unit 201 passes the acquired information to the job execution unit 204 to execute the job.

In S920, the job execution unit 204 executes the document processing of the first <process> element of the document processing flow definition document. According to the document processing flow definition of FIG. 4, the processing of character region extraction is described as the first processing of the order attribute 1. Therefore, the job execution unit 204 executes the character extraction process over the entire area of the input form image data. Then, the job execution unit 204 temporarily stores the input form image data and the processing result output data (here, the extracted character image data) in the storage unit 207 in association with the job identification number.

In S930, the job execution unit 204 determines whether or not all the processing procedures described in the document processing flow definition have been executed, and if all the procedures have been executed, go to S940, and if there is unexecuted document processing, go to S920. Loop and perform the next document processing. In the document processing flow definition of FIG. 4, there is character recognition (charactor recognition) of "order attribute 2" next to the character area extraction process. Therefore, the job execution unit 204 executes the character recognition process for the previously extracted character image in the second S920. At this time, the document processing job execution unit 204 temporarily stores the character image to be recognized and the character recognition result (character code) in the storage unit 207 in association with the job identification number. Next, in the third S920, the information extraction (information extraction) process of the "order attribute 3" is also performed in the same manner. According to the flow definition document of FIG. 4, the job execution unit 204 receives the character recognition result and extracts the patient identification information (patient-id) from the character string which is the character recognition result. Further, the job execution unit 204 also extracts the document type information (document-type) and the name of the clinical department to which the document belongs (department-name). The job execution unit 204 associates the character recognition result with the extracted patient identification information (patient-id), document type information (document-type), and document belonging clinical department name (department-name) with the job identification number. It is stored in the storage unit 207. When this extraction is completed, there is no processing to be performed next, so the job execution unit 204 finishes the processing. At this time, the job execution unit 204 notifies the document processing job management unit 201 of the end of the corresponding job.

The processing proceeds to S940 when the document processing flow execution of the job acquired in S900 is completed. Therefore, the job management unit 201 updates the job status of the job from "running" to "waiting for confirmation" in order to put the user in the waiting state for the execution instruction of the correction confirmation, and waits until the confirmation process execution instruction is given. To do. The job display unit 203 updates the display screen in response to this status update.

In S950, the job management unit 201 determines whether or not the result confirmation execution instruction of the job is given from the document processing job execution control monitor shown in FIG. In FIG. 3, it is assumed that the job status of the job identification number “00182938” is “waiting for confirmation” and the user clicks “execute” for this job. In this case, the confirmation process for the job identification number “00182938” is executed. Therefore, the job management unit 201 passes the job identification number “00182938” instructed by the user to the job execution result correction unit 205 to make corrections.

In S960, the job execution result correction unit 205 controls the job display unit 203, displays an edit screen for correcting the document processing job result specified by the user, and performs the correction process. FIG. 5 is an example of the display screen. Then, in S970, the job execution result correction unit 205 corrects and confirms. Details of the correction confirmation process by the job execution result correction unit 205 will be described later with reference to FIGS. 5 to 8A and 8B.

In S980, the job management unit 201 determines, as a result of the correction confirmation in S970, whether or not a reproduction process for reflecting the correction result in the next flow execution is necessary. The reproduction process is a process of storing the correction result for the document process included in the document processing flow once performed. The next time the document is processed again, the stored correction result is output (reproduced). If any of the <result> elements of the modified document (or editing information) of the document processing flow execution result shown in FIG. 8B has the change attribute of "1", the reproduction processing is required. In addition, if there is no <result> element with the change attribute, it is determined that the correction was not made only by checking the result, the playback process is unnecessary, and the job status is updated from "waiting for confirmation" to "completed" and the document processing flow. End the execution of control.

When it is determined that the reproduction process is necessary, in S990, the job management unit 201 requests the modification result reproduction unit 206 to execute the reproduction process for reflecting the modification result in the next flow execution. In addition, the job management unit 201 updates the corresponding job status from "waiting for confirmation" to "reproduction completed" and ends the execution of the document processing flow control. The details of the correction result reproduction processing of S990 by the correction result reproduction unit 206 will be described later with reference to FIG.

Next, the correction process by the job execution result correction unit 205 in the embodiment in S960 will be described. FIG. 5 is an example of an edit screen for correcting the document processing job result. In the figure, reference numeral 500 is a window for displaying an edit screen for confirming and correcting the job execution result. Reference numeral 501 is an area for displaying the job identification number of the correction confirmation target for which confirmation execution instruction is given in FIG. Reference numeral 502 displays the entire processing target form image of the job as a reduced image, and a part 503 of the form image is enlarged and displayed in the display area 504. A part 503 of the reduced form image is hatched and displayed in order to confirm which position is displayed in the display area 504.

The details will be clarified from the following description, but FIG. 5 shows an example in which the job execution unit 204 extracts the “inspection report” as the document type information (document-type) as originally intended. Then, in FIG. 5, the job execution unit 204 erroneously extracts the examination ID “3579090” where “123456” should be extracted as the patient information (patient-id), and “department-name” as the belonging clinical department name (department-name). It shows the case where "general clinical department" is mistakenly extracted where "chest and abdomen examination center" should be extracted.

As shown in FIG. 5, in order to make it possible to easily grasp where the information of the three output results (patient number, document type, clinical department) is drawn in the image to be processed, the rectangular frame 505 and the respective are respectively. 506 and 507 are displayed.

Reference numeral 508 is an attribute (or item name) of the extraction information which is the processing result, and reference numeral 509 is an area for displaying the value of the extraction information. When a specific cell area of the extraction result display area 509 is specified by clicking or the like, it is highlighted together with the corresponding rectangular area display. In FIG. 5, the cell with the patient number “3579090” and the rectangular area 507 are highlighted as the corresponding extraction results. Reference numeral 510 is an input area for modifying the extraction result. Further, reference numeral 511 is an icon displayed when there are other extraction candidates, and when clicked, a candidate list is displayed below the icon and can be selected. The reference code 512 is a completion button, and the user presses the button when completing the confirmation / correction operation.

FIG. 6 is a display example when the candidate display icon 511 of FIG. 5 is clicked. If there are other candidate results, clicking this icon 511 will display the candidates, and by selecting one of them, the selected candidate will be displayed in the correction result input field 510. In the illustration, another candidate "123456" of the patient information is displayed as the candidate list 602, and by clicking this candidate, the edit result input field 510 corresponding to the patient number can be updated. At this time, the character input cursor is blinking in one of the correction result input fields 510 (in the figure, the variable result input field 510 corresponding to the patient number). The user can perform editing operations such as inserting and deleting characters from a keyboard (not shown) or the like. Also, the rectangular area 507 recognized as the patient number is highlighted, but this is an incorrect area. Therefore, the area designation cursor 601 may be moved by mouse operation to specify the correct rectangular area 600. It is possible. In the illustrated case, since the rectangular area 600 indicates the original patient number, the user sets two diagonal points of the rectangular area 600 with the area designation cursor 601. When the correct rectangular area 600 is reset, the job execution result correction unit 205 searches for the character recognition result (stored in the storage unit 207) at the corresponding position, and displays the result in the correction result input field 510. To do. When this correct area is set, the user may directly input the correct patient number “123456” into the correction result input field 510 from the keyboard or the like. As described above, either the operation by the candidate list 602, the resetting of the rectangular area by the area designation cursor 601 with the extraction result to be corrected selected, or the direct input to the edit result input field 510, the patient You can correct the information.

FIG. 7 shows another example in which the processing result is modified by designating the rectangular area to be the output result. In FIG. 7, although the “general clinical department” is incorrect as a result of being extracted as a clinical department, other candidates are not displayed. Therefore, two diagonal points of the rectangular area 702 are set by the rectangular area designation cursor 701. When the rectangular area 702 is determined, the job execution result correction unit 205 executes character recognition processing in the designated area and displays the result in the correction result input field 510.

FIG. 8A shows a state in which the process of correcting the execution result of the document processing flow is completed. By the operation of FIGS. 5 to 7, the patient number and the clinical department are corrected in the document processing flow execution result and entered in the correction result input field, and the rectangular area frame 801 corresponding to the final confirmation result of the extraction result, 802 and 803 are displayed. When the user presses the "done button" in this state, the correction process by the execution result correction unit 206 ends.

FIG. 8B is an example of a document processing flow execution result correction document generated by the execution result correction unit 206 when the completion button is pressed in FIG. 8A. This modified document verified_result stores the region coordinates of the modified or confirmed processing result, the data type, and the set of the values as the reset element. Further, when the processing result is modified, the change attribute is added to the reset element.

FIG. 10 is an operation flowchart of the processing of the correction result reproduction unit 206 in S990 of FIG. Hereinafter, the processing of the correction result reproduction unit 206 will be described with reference to the figure.

In S1000, the correction result reproduction unit 206 acquires the processing procedure from the document processing flow definition of the job for which the execution result of the document processing flow has been confirmed. In S1010, the modification result reproduction unit 206 sequentially executes the processing in S1020 at the end of the processing procedure, that is, in descending order of the order attribute from the processing in which the order attribute in the process element of FIG. 4 is maximum.

In S1020, the correction result reproduction unit 206 executes the process acquired in S1010 in a reproduction mode for storing a result different from the normal document processing execution. In this reproduction mode, the modification result reproduction unit 206 determines whether or not each process includes the output result also specified in the result of processing the specified input data. Then, if it is included, the correction result reproduction unit 206 stores the correction information of the document processing result stored in the storage unit 207 in a table (hereinafter referred to as a correction table) so as to obtain a result to be output. .. This modification table will be described later with reference to FIG. When the document processing is executed, if the pattern stored in the modification table exists, the stored pattern is output.

When the correction result reproduction unit 206 determines in S1030 that all the outputs described in the correction result document of FIG. 8B are stored in the correction table so as to be reproducible, the present process is terminated. If there is a correction result that cannot be reproduced, the process proceeds to S1040.

In S1040, the correction result reproduction unit 206 determines whether or not all the processing procedures acquired in S1000 have been completed. If it is determined that the process is completed, the process proceeds to S1050, and if not, that is, if there is an unexecuted process, the process loops to S1020 and is executed in the playback mode.

In S1050, the correction result reproduction unit 206 stores all the correction results that are not reproducible in the correction table and ends when all the processing procedures are completed. To do.

11 (a) and 11 (b) show an example of the input information referred to when the correction result reproduction unit 206 executes the information extraction process in the reproduction mode. Since the information extraction process extracts a specific character string in the document image in consideration of the layout information, the correction result reproduction unit 206 inputs the character string data which is the character recognition result and the area coordinate information thereof. FIG. 11B is input information storing the character recognition result extracted from the document image shown in FIG. 11A. The region element is the character recognition result in one character area, and the region elements of id attributes 1, 2, ..., 8 correspond to the reference codes 1101, 1102, ..., 1108 of FIG. 11 (a), respectively. Although omitted in the middle in FIG. 11B, the id attributes 3, 4, 5, 6 and 7 also correspond to the respective rectangular display areas in FIG. 11A. On the other hand, the "chest and abdomen examination center" shown in FIG. 11 (a) is not recognized as a character area, and the corresponding character information is not stored in FIG. 11 (b). A plurality of character recognition result char elements can be stored in each region element, and are identified by the can attribute. For example, the character recognition result having the region element id 1 stores two candidate character strings, that is, the "inspection report" of the cand attribute 1 and the "inspection report" of the cand attribute 2. Based on these input data, the correction result data, FIG. 8B, is registered in the correction table so that it can be reproduced. In the case of FIG. 8B, the “inspection report” in which the id of the result element of the correction result is 2 and the “123456” in which the id is 3 are included in the input information as options 1101 and 1104. Therefore, it can be said that the correction result can be reproduced in the information extraction processing, but since the "chest and abdomen medical examination center" in which the id of the result element of the correction result is 1 is not included as an option in the input information, the information extraction processing The correction result cannot be reproduced because it is not processed by.

12 (a) and 12 (b) show an example of input information referred to when the correction result reproduction unit 206 executes the character recognition process in the reproduction mode. Since the character recognition process recognizes the character pattern in the area where the characters in the document image are drawn and outputs the character code string, the area coordinates where the characters are drawn are input. FIG. 12B is input information storing the character drawing area coordinates extracted from the document image shown in FIG. 12A. The region element is one character drawing area, and the region elements of id attributes 1, 2 and 8 correspond to the reference codes 1101, 1102 and 1108 of FIG. 11 (a), respectively. Although omitted in the middle of FIG. 12B, the id attributes 3, 4, 5, 6 and 7 also correspond to the respective character drawing areas of FIG. 12A. Based on these input data, the correction result data, FIG. 8B, is registered in the correction table so that it can be reproduced. In the case of FIG. 12A, the “inspection report” in which the id of the result element of the correction result is 2 and the “123456” in which the id is 3 are included in the input information as options 1201 and 1204. Therefore, it can be said that the correction result can be reproduced by the character recognition processing, but since the "chest and abdomen medical examination center" in which the id of the result element of the correction result is 1 is not included as an option in the input information, the character recognition processing It is not processed and the correction result cannot be reproduced.

FIG. 13 is a diagram showing an example of a correction table stored to make the correction result reproducible. The modification table is configured to be held in the RAM 103, held in an external storage device (not shown) via the communication unit 106, or held in an external storage device (not shown) connected to the bus 107.

The field 1300 is input data identification information, and stores the URL (Universal Resource Locator) of the storage location that holds the input image data to be stored. The fields 1301, 1302, 1303, and 1304 store the X coordinate and Y coordinate of a specific rectangular area in the input data, the number of pixels representing the height of the area, and the number of pixels representing the width of the area, respectively. The field 1306 is image data constituting a specific area indicated by the fields 1301 to 1304, and stores the pixel data array constituting the image, the feature amount data array calculated from the pixel data array, and the like, and the field 1305 is the data. Store the size. The field 1307 is a data attribute of the content drawn in the specific area indicated by the fields 1301 to 1304, and in the present embodiment, any one of "patient number", "document type", and "clinical department" is stored. .. The field 1308 stores the content drawn in the specific area indicated by the fields 1301 to 1304.

As described above, according to the first embodiment, the result of modification (editing) by the user for the job (process leading to the extraction of the character string of the preset item) for the form image is prioritized when the next job is executed. Will let you. For example, if a form image with a different layout but the same purpose is input, and if there is a "chest and abdomen examination center" in it, it will be extracted as the department name (department-name) of the document. ..

[Second Embodiment]
In the first embodiment described above, the flow is defined so that the processing result executed based on the document processing flow definition is corrected when the user does not want it, and the correction result is reproduced at the next document processing flow execution. The correction result was memorized by executing the processing in reverse order.

In the second embodiment, the correction result is stored by redefining the flow definition document of the document processing so that the correction result is reproduced and executed.

FIG. 14 shows an example of a document processing flow definition document that describes the reproduction storage process to be executed in order to reproduce the correction result. The process element that defines the processing order is the same as in FIG. 4, but the feedback element that is the reproduction storage processing definition unit is added. The feedback element stores a process of executing the reproduction storage process according to the modification result element of FIG. 8B. result_type indicates a modification result element, and if it is a region, it corresponds to the region element in FIG. 8B. The process element stores the process to be executed for the reproduction storage process for the specified result_type. Similar to the document processing flow definition in FIG. 4, a plurality of processes can be concatenated by adding an orderer attribute.

In the correction result reproduction processing using FIG. 14, after the processing procedure is acquired, the correction result reproduction storage is executed by acquiring and executing the processing for reproducing and storing the correction result element included in the correction result from the feedback element. To.

[Third Embodiment]
In the first and second embodiments, the modification result of the same type of workflow job is reproduced by configuring the storage information for reproducing the modification result to be unconditionally stored. On the other hand, the possibility that the results of other jobs may change by utilizing the regenerated memory information is considered. Therefore, the document processing jobs executed in the past are accumulated, the reproduction storage information is applied, and the accumulation job is re-executed, and the reproduction storage information is left only when the ratio for obtaining the correction result becomes a certain predetermined value or more. If not, the reproduction storage information is deleted. Further, when the reproduction storage information is deleted, "unreproducible" is added as a display status to the job status 302 of FIG.
