Description

  The present invention relates to a document management program, a document management method, and a document management apparatus for digitizing and managing a document.

  2. Description of the Related Art Conventionally, there is a document management apparatus that digitizes documents such as documents and forms and stores them in a storage device for management. This document management apparatus has a registration function and a search function for documents having a plurality of related documents and forms. At the time of registration, image data of documents and forms is collected in units of documents, and one index is assigned and stored in the storage device. At the time of search, image data for each document stored in the storage device is extracted using an index.

  However, some documents include a plurality of indexes in one document. For example, in a group insurance application document, a plurality of contractors are registered in one document. One document includes group insurance application documents and contract-related documents for each contractor. In this case, it is preferable to manage by assigning an index to the document corresponding to each contractor as well as the entire document. FIG. 18 is a diagram illustrating an example of management of a document including a plurality of conventional indexes. The application document 910 to be managed includes an application document ABC911, an attached document (A) 912, an attached document (B) 913, and an attached document (C) 914. In the application document ABC911, “securities number A”, “securities number B”, and “securities number C”, which are indexes for identifying the attached documents, are described. “Securities number A” corresponds to the attached document (A) 912, “Securities number B” corresponds to the attached document (B) 913, and “Securities number C” corresponds to the attached document (C) 914, respectively. Hereinafter, the document in which the index of the attached document is described is referred to as a representative form, and the attached document associated with the representative form by the index described in the representative form is referred to as an incidental form.

  In the conventional document management apparatus 900, image data 931 of all documents included in the application document 910 is stored in an image database (hereinafter referred to as DB) 930, and one index is assigned. In the example of FIG. 18, the image data of the application document 910 is character-recognized, and the “stock number A” at the head of the index item is extracted and used as an index. The index “securities number A” is registered in the index DB 920 in association with the address where the image data 931 is stored. In order to enable a search based on “security number B”, an index may be generated for “security number B”. In this case, the operator again causes the document management apparatus 900 to perform the same processing as described above using the image data of the application document ABC911. The document management apparatus 900 stores the image data 932 of the application document ABC in the image DB 930 and extracts the index “securities number A”. Therefore, the operator manually replaces “securities number A” with “securities number B”. The operator performs the same process for “Securities Number C”. Thus, in the image DB 930, the entire image data 931 of the application document 910 associated with the index “Securities number A”, the image data 932 of the application document ABC associated with the index “Securities number B”, and the index “ The image data 933 of the application document ABC associated with the “security number C” is stored.

  In the management of multimedia information, which is a collection of different types of information data such as image data, audio data, text data, etc., an attribute index corresponding to the included information data is assigned to the multimedia information instead of one index. However, there is a method for facilitating the search (see, for example, Patent Document 1).

JP 2002-7418 A

Conventional document management has a problem that it is not easy to manage a document including a plurality of indexes.
As described above, in order to manage a document in which a single document includes a plurality of indexes with a plurality of indexes, the operator reads as many representative forms as the number of indexes to be registered, and replaces the obtained indexes. The burden on the operator was great. In the example of FIG. 18, it is necessary to repeatedly read the application document ABC911 for “security number B” and “security number C” and to replace the obtained index. Since this operation is performed manually by the operator, there is a high possibility that a registration error will occur. Furthermore, the storage device has to store the image data of the representative forms corresponding to the number of indexes, and there is a problem that if the number of indexes increases, the storage amount of the storage device is compressed.

  Even in the search, there is a problem that image data cannot be directly acquired for the added index. In the example of FIG. 18, when it is desired to confirm the attached document (B) of “Securities No. B”, first, “Securities No. B” is specified and the image data 932 of the application document ABC is acquired. However, there is no image data for attached documents. Therefore, based on the image data 932 of the application document ABC displayed on the display device, the “stock number A” at the head of the index is confirmed, and the “stock number A” is designated to obtain the entire image data 931. As described above, a complicated operation is required even during a search.

  In view of such a point, an object of the present invention is to provide a document management program, a document management method, and a document management apparatus capable of facilitating document management of a document including a plurality of indexes.

  In order to solve the above problems, a document management program is provided that allows a computer that performs document management processing to digitize and manage documents to function. This document management program causes a computer to function as a recognition unit, a registration unit, and a search unit. The recognizing unit has a representative form and an incidental form attached to the representative form, and acquires image data obtained by digitizing a document in which an index for identifying the incidental form associated with the representative form is described in the representative form. Then, character recognition is performed on the image data of the representative form to extract all indexes described in the representative form. The registration unit stores the acquired document image data in the image data storage unit, and registers the address storing the document image data in the index management information in association with the index extracted from the representative form of the document. When a search target index is specified, the search means searches the index management information based on the specified index, and extracts document image data corresponding to the specified index.

  In order to solve the above problems, there are provided a document management method and a document management apparatus that execute the same processing procedure as that of a computer that executes the document management program.

  According to the disclosed document management program, document management method, and document management apparatus, when a document is registered, all indexes are extracted, and the extracted indexes are associated with document image data. In this way, since all the indexes are extracted by reading the image data once, it is possible to improve the work efficiency when registering the operator. Further, at the time of retrieval, document image data can be easily acquired based on the index, and work efficiency at the time of retrieval can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual diagram of the invention applied to the embodiment.
The document management apparatus 1 includes a reading unit 1a, a recognition unit 1b, a registration unit 1c, and a search unit 1d. The document management apparatus 1 generates an index and registers image data of the document 5 and an image of the registered document 5 Performs search processing to retrieve data.

  The document 5 to be managed has a representative form 5a and N attached forms 5b (N is an integer of N ≧ 0) attached to the representative form 5a. Here, it is assumed that the form indicates a document in which information is described in a predetermined format. In the representative form 5a, information for identifying the incidental form 5b is described as an index. The representative form 5a includes a normal form in which one index is set for the document 5 and a comprehensive form in which a plurality of indexes are set. In the case of a normal form, the document 5 has a representative form 5a in which one index is described and one incidental form 5b related to the index. In the case of a comprehensive form, the document 5 has a representative form 5a in which M (M is an integer of M ≧ 0) indexes are described, and M types of incidental forms 5b associated with each index.

  The reading unit 1a controls, for example, a scanner, reads an image image of the document 5 to be managed, and generates image data thereof. The reading unit 1a sequentially reads the image images of the representative form 5a and the accompanying form 5b included in the document 5, and outputs the image data to the recognition unit 1b in the order of reading. Here, it is assumed that the document 5 has the incidental form 5b arranged in the order of the index described in the representative form 5a with the representative form 5a at the top. The read image data is output in the order of the image data of the representative form 5a, the image data of the attached form corresponding to the index described at the head, and the image data of the attached form corresponding to the next described index. Note that the reading unit 1a may input image data already digitized for the document 5 from the outside.

  The recognizing unit 1b extracts an index from the image data of the representative form 5a of the image data of the document 5 acquired by the reading unit 1a. The recognizing unit 1b determines the form type of the image data acquired from the reading unit 1a, and if it is the representative form 5a, extracts the index. At this time, if the representative form 5a is a normal form, one index is extracted, and if the representative form 5a is a comprehensive form, all indexes described in the representative form 5a are extracted. For example, based on the area definition of data predetermined for each form, the area where the index is described is detected, and the image data is extracted. Then, a character recognition process is performed on the extracted image data, and the obtained word is extracted as an index. The image data acquired from the reading unit 1a and the extracted index are output to the registration unit 1c.

  The registration unit 1c collects the image data read by the reading unit 1a in document units, stores the image data 3c in document units in the storage device 3, and generates and manages individual indexes and document indexes. The document-unit image data 3c is arranged in the order of representative form image data and incidental form image data in accordance with the reading order. The document index is identification information for identifying a document, and is associated with a storage area of image data for each document. In the example of FIG. 1, a document index for identifying the document 5 is generated and associated with the address of the image data 3 c of the document 5 stored in the storage device 3. The generated document index and the address of the image data 3c of the document unit of the associated document 5 are registered in the document index management information 3b. The document index is the same regardless of whether the representative form 5a is a normal form or a comprehensive form. The individual index is an index described in the representative form 5a extracted by the recognition unit 1b. As the image data of the form, one piece of image data 3c in document units is stored. Therefore, regardless of the index to be searched, the image data 3c in document units is extracted. Therefore, the individual index is associated with the storage address of the image data 3c in document units. Here, since the document index is associated with the image data 3c in document units, the document index of the document described in the individual index is associated. The document index is associated with the individual index extracted by the registration unit 1c and the recognition unit 1b and registered in the individual index management information 3a.

  When an index is designated by the user or the like, the retrieval unit 1d extracts image data of a document including an incidental form corresponding to the designated index and provides it to the user. First, the individual index management information 3a is searched based on the designated index, and the document index corresponding to this index is detected. Subsequently, based on the detected document index, the document index management information 3b is searched, and the address where the image data of the document unit of this document is stored is detected. Then, based on the detected address, the document-unit image data 3c including the attached form of the designated index is read and provided as document image data 7 to the request source.

  The operation of the document management apparatus 1 will be described. In the document registration process, when the document 5 having the representative form 5a and the incidental form 5b is designated, the reading unit 1a sequentially acquires the image data of each form of the document 5 and outputs it to the recognition unit 1b. The image data is input in the order of the form, starting with the image data of the representative form 5a. The recognizing unit 1b discriminates the form type of the image data to be sequentially input, and if it is the representative form 5a, extracts the index. If the representative form 5a is a normal form, one index is extracted. If the representative form 5a is a comprehensive form, all indexes to be described are extracted. The index is extracted by extracting image data of a predefined area and performing character recognition. The registration unit 1 c stores document data image data 3 c in which image data of the document 5 read by the reading unit 1 a is collected in a predetermined storage area of the storage device 3. Then, the document 5 is associated with the document index for identifying the document 5 and is registered in the document index management information 3b in association with the address where the image data 3c for each document is stored. Next, an individual index is generated using the index described in the representative form 5a recognized by the recognition unit 1b, and the document index of the document 5 is associated and registered in the individual index management information 3a.

  In the document search process, an index is designated and the search is started. The search unit 1d searches the individual index management information 3a based on the specified index, and detects the document index of the document including the incidental form of the specified index. Then, the document index management information 3b is searched based on the detected document index, and an address where the document-unit image data 3c of this document is stored is detected. Then, based on the detected address, the image data 3c stored in the storage device 3 is extracted and output to the search request source as the image data 7 of the document.

  As described above, at the time of registration, the indexes described in the representative form 5a are collectively read, and the image data for each document is associated with the recognized individual indexes. For this reason, even if it is a comprehensive form, the operation | work which reads the representative form 5a repeatedly becomes unnecessary, can reduce a burden of an operator, and can improve work efficiency. Since a plurality of individual indexes set for a document are associated with the image data of the document, the image data of the target document is extracted if the individual index is designated at the time of retrieval. For this reason, it is not necessary to repeat the search to obtain the desired data, and the search efficiency can be increased. As a result, the efficiency of registration processing and search processing of documents including a plurality of indexes is improved, and document management can be facilitated.

Next, the document management apparatus shown in FIG. 1 will be described in detail with reference to the drawings, taking as an example the case where the document management apparatus is applied to the management of insurance application documents and attached documents.

  Peripheral devices connected to the bus 109 include a hard disk drive (HDD) 103, a graphic processing device 104, an input interface 105, an optical drive device 106, a scanner control device 107, and a communication interface 108.

  The HDD 103 magnetically writes and reads data to and from the built-in disk. The HDD 103 is used as a secondary storage device of the document management apparatus 100. The HDD 103 stores an OS program, application programs, and various data. The document data storage device 300 may function. Note that a semiconductor storage device such as a flash memory can also be used as the secondary storage device.

  A monitor 600 is connected to the graphic processing device 104. The graphic processing device 104 displays an image on the screen of the monitor 600 in accordance with a command from the CPU 101. Examples of the monitor 600 include a display device using a CRT (Cathode Ray Tube) and a liquid crystal display device.

  A keyboard 601 and a mouse 602 are connected to the input interface 105. The input interface 105 transmits signals sent from the keyboard 601 and the mouse 602 to the CPU 101. Note that the mouse 602 is an example of a pointing device, and other pointing devices can also be used. Examples of other pointing devices include a touch panel, a tablet, a touch pad, and a trackball.

  The optical drive device 106 reads data recorded on the optical disk 603 using a laser beam or the like. The optical disk 603 is a portable recording medium on which data is recorded so that it can be read by reflection of light. The optical disk 603 includes a DVD (Digital Versatile Disc), a DVD-RAM, a CD-ROM (Compact Disc Read Only Memory), a CD-R (Recordable) / RW (ReWritable), and the like.

  The scanner control device 107 is connected to the scanner 200, instructs the scanner 200 to read an image in accordance with an instruction from the CPU 101, and transmits image data acquired from the scanner 200 to the CPU 101.

  The communication interface 108 is connected to the network 604. The communication interface 108 transmits and receives data to and from other computers or communication devices via the network 604.

  When the document data storage device 300 is provided externally, it can be connected to the document management device 100 via an interface connected to the internal bus 109 or via the network 604. With the hardware configuration as described above, the processing functions of the present embodiment can be realized.

  Next, the software configuration of the document management apparatus 100 will be described. FIG. 4 is a block diagram showing a software configuration of the document management apparatus. The document management apparatus 100 includes a reading unit 110, a recognition unit 120, an inspection unit 130, a registration unit 140, a search unit 150, and a display unit 160. The document data storage device 300 is provided with an individual index DB 310, a document index DB 320, and an image DB 330.

  The reading unit 110 controls the operation of the scanner 200 and acquires image data of the document 500 read by the scanner 200. The acquired image data is output to the recognition unit 120 in the order of reading.

  The recognition unit 120 includes a form determination unit 121 and a character recognition unit 122. The form discriminating unit 121 discriminates whether the type of the form input from the reading unit 110 is a representative form or an accompanying form, and if it is a representative form, it is a normal document or a comprehensive form. For example, the form type described at a predetermined position on the form is read and determined. Alternatively, the characteristics of each form may be defined in advance, and the form may be identified by comparing with the characteristics obtained from the read image data. If the image data is an accompanying form, it is output to the inspection unit 130 as it is. When the representative form is detected, it is determined whether the representative form is a normal form or a comprehensive form, and is output to the character recognition unit 122 together with the determination result. The character recognition unit 122 extracts an index described in the image data of the representative form. The index is information for identifying an incidental form attached to the representative form, and which of the items described in the representative form is determined as an index. An area where an index is described is also defined in advance. When the representative form is a normal form, character recognition processing is performed on image data in a predefined area, and one index is extracted. If the representative form is a comprehensive form, character recognition processing is performed on image data in a predefined area, and M indexes are extracted. The image data of the representative form and the extracted index are output to the inspection unit 130.

  The inspection unit 130 displays the image data of the document 500 read by the reading unit 110, the index extracted by the recognition unit 120, and the like on the display unit 160, and is checked by the operator. The operator looks at the image data displayed on the display unit 160 and checks the order of the read documents and reading errors. In addition, the index extracted by the recognition unit 120 is checked to check whether the character has been correctly recognized or not missing. The image data and the index that have undergone such operator inspection are output to the registration unit 140.

  The registration unit 140 divides the image data of the document that has been checked by the operator into document units and stores it in the image DB. Further, a document index and an individual index are generated and stored in the document index DB 320 and the individual index DB 310, respectively.

  Upon receiving a search request for image data of a document stored in the image DB 330, the search unit 150 searches the individual index DB 310 and the document index DB 320 using the specified search keyword, and the image of the document corresponding to the specified keyword. Extract data. Then, the extracted image data is displayed on the display unit 160, for example. The extracted image data can be output to a printing device and printed, or can be output to an external storage device.

The display unit 160 displays an image of the document 500 based on the image data, an index, and the like on the display screen in accordance with instructions from the inspection unit 130 and the search unit 150.
The individual index DB 310 manages individual index management information used when searching for image data of documents stored in the image DB 330.

  The document index DB 320 manages document index management information in which a document index for identifying one document is associated with an address where image data for the document is stored.

The image DB 330 stores image data in units of documents.
Hereinafter, the operation of the document management apparatus 100 will be described using a specific example of the document 500. FIG. 5 is a diagram showing an example of a document. The document management apparatus 100 registers and manages image data of the document ABC 510, the document D 520, the document E 530, and the document F 540. The document shown in FIG. 5 is assumed to be managed by using the security number as an index.

  The document ABC 510 includes an application document ABC 511 that is a representative form, an attached document (A) 512, an attached document (B) 513, and an attached document (C) 514 that are incidental forms. The application document ABC511 is a comprehensive form, in which “A”, “B”, and “C” are described as securities numbers of a plurality of contractors. This security number is also identification information for identifying the attached document (A) 512, attached document (B) 513, and attached document (C) 514 of each contractor attached to the application document ABC 511. For example, the document ABC 510 has the application documents ABC 511 at the top, and the attached documents corresponding to the respective securities numbers are arranged in the order of the securities numbers described in the application documents ABC 511. In the example of FIG. 5, the securities number has an attached document (A) 512 corresponding to “A”, an attached document (B) 513 corresponding to “B”, and an attached document (C) 514 corresponding to “C”. .

  The document D520 includes an application document D521 that is a representative form and an attached document (D) 522 that is an accompanying form. The application document D521 is a normal form, and only the securities number “D” of one contractor is described. Further, it has an attached document (D) 522 corresponding to “D”. The document E530 includes an application document E531 that is a representative form and an attached document (E) 532 that is an accompanying form. The document F540 includes an application document F541 that is a representative form and an attached document (F) 542 that is an accompanying form.

  Next, registration processing of the document ABC 510, the document D 520, the document E 530, and the document F 540 of the document management apparatus 100 will be described. First, registration processing of the document ABC510 having a comprehensive form will be described, and subsequently, registration processing of the document D520, the document E530, and the document F540 having a normal form will be described.

  FIG. 6 is a diagram showing document registration processing when the representative form is a comprehensive form. The document ABC 510 is a document in which a representative form is a comprehensive form, and includes an application document ABC 511 that is a representative form, an attached document (A) 512, an attached document (B) 513, and an attached document (C) 514.

  The reading unit 110 reads images in the order of the application document ABC511, the attached document (A) 512, the attached document (B) 513, and the attached document (C) 514, and generates the image data. The recognizing unit 120 determines the form of the image data read by the reading unit 110, and extracts an index when the form is a representative form. In the example of FIG. 6, first, the application document ABC511 is recognized as a representative form and a comprehensive form, and N indexes are extracted. Here, three indexes 1201 of “A”, “B”, and “C” are extracted for the security number. The attached document (A) 512, the attached document (B) 513, and the attached document (C) 514 are discriminated as accompanying documents, and recognition processing is not performed.

  The image data of each form and the index 1201 are delivered to the inspection unit 130. The inspection unit 130 displays the image data on the display unit 160 and waits for an operator's inspection. The index 1201 is also displayed on the display unit 160. The image data 5111 of the application document ABC checked by the operator, the image data 5121 of the attached document (A), the image data 5131 of the attached document (B), the image data 5141 of the attached document (C), and the index 1201 140 is delivered.

  The registration unit 140 divides the image data into document units, and stores the document unit image data in the image DB 330. In the example of FIG. 6, the image data 5111 of the application document ABC, the image data 5121 of the attached document (A), the image data 5131 of the attached document (B), and the image data 5141 of the attached document (C) are arranged in this order. Store in the DB 330. Also, a document index “INDEX-A” relating to the document ABC 510 is generated, associated with the image data storage address of the document ABC 510 in the image DB 330, registered in the document index management information, and set in the document index DB 320. Then, an individual index is generated based on the index 1201 extracted from the application document ABC511. In the example of FIG. 6, “A”, “B”, and “C” of the index 1201 extracted by the recognition unit 120 are associated with the document index “INDEX-A” indicating the image data of the document 510, respectively, and the individual index management information And set in the individual index DB 310. An individual index can be generated first, and a document index can be generated later.

  FIG. 7 is a diagram showing document registration processing when the representative form is a normal form. The document D520 and the document E530 are documents in which the representative form is a normal form, and includes an application document D521 and an attached document (D) 522, and an application document E531 and an attached document (E) 532, respectively. Although omitted in the example of FIG. 7, the same applies to the document F540.

  The reading unit 110 reads images in the order of application document D521, attached document (D) 522, application document E531, and attached document (E) 532, and generates image data thereof. The recognizing unit 120 determines the form of the image data read by the reading unit 110, and extracts an index when the form is a representative form. In the example of FIG. 7, first, the application document D521 is recognized as a representative form and a normal form, and one index is extracted. Here, an index 1202 “D” is extracted for the security number. The attached document (D) 522 is determined as an accompanying form, and recognition processing is not performed. The next application document E531 is recognized as a representative form and a normal form, and one index is extracted. Here, an index 1203 “E” is extracted. The attached document (E) 532 is determined as an incidental form, and recognition processing is not performed.

  The image data of each form and the indexes 1202 and 1203 are delivered to the inspection unit 130. The inspection unit 130 displays the image data on the display unit 160 and waits for an operator's inspection. The indexes 1202 and 1203 are also displayed on the display unit 160. The image data 5211 of the application document D that has been checked by the operator, the image data 5221 of the attached document (D), the image data 5311 of the application document E, the image data 5321 of the attached document (E), and the indexes 1202 and 1203 140 is delivered.

  The registration unit 140 divides the image data into document units, and stores the document unit image data together in the image DB 330. In the example of FIG. 7, a document unit of image data 5211 of application document D and image data 5221 of attached document (D), a document unit of image data 5311 of application document E and image data 5321 of attached document (E), Are stored in the image DB 330 while maintaining this order. Also, a document index “INDEX-D” corresponding to the document D520 is generated and registered in the document index management information stored in the document index DB 320 in association with the area where the image data of the document D520 is stored. Similarly, for the document E530, an index “INDEX-E” corresponding to the document E530 is generated and registered in the document index management information stored in the document index DB 320 in association with the area in which the image data of the document E530 is stored. . Then, an individual index of the index 1202 extracted from the application document D521 is generated. In the example of FIG. 7, “D” of the index 1202 extracted by the recognition unit 120 is associated with the document index “INDEX-D” and registered in the individual index management information stored in the individual index DB 310. Similarly, “E” in the index 1203 is associated with the document index “INDEX-E” and registered in the individual index management information. Individual index management information is managed by the individual index DB 310.

  FIG. 8 is a diagram showing the relationship of indexes. The individual index 311 includes the application number ABC511, the application document D521, the application document E531, and the securities number “A”, “B”, “C”, “D”, “E”, “E” extracted from the application document F541. F ". The individual index 311 is linked to the document index 321 of the document to which each belongs. In the example of FIG. 8, the individual indexes “A”, “B”, and “C” extracted from the application document ABC511 of the document ABC510 are associated with the document index “INDEX-A” of the document ABC510. The individual index “D” extracted from the application document D521 of the document D520 is associated with the document index “INDEX-D” of the document D520. The individual index “E” extracted from the application document E531 of the document E530 is associated with the document index “INDEX-E” of the document E530. The individual index “F” extracted from the application document F541 of the document F540 is associated with the document index “INDEX-F” of the document F540.

  The document index 321 is associated with an address indicating a storage area in which image data 331 of each document is stored, for example, a head address of a storage area in which image data in units of documents in the image DB 330 is stored. In the example of FIG. 8, the document index “INDEX-A” of the document ABC 510 includes the application document ABC image, the attached document (A) image, the attached document (B) image, and the image data of the document ABC having the attached document (C) image. Are associated with the storage area. The document index “INDEX-D” of the document D520 is associated with the image data storage area of the document D520 having the application document D image and the attached document (D) image. The document index “INDEX-E” of the document E530 is associated with the image data storage area of the document E having the application document E image and the attached document (E) image. The document index “INDEX-F” of the document F540 is associated with the image data storage area of the document F having the application document F image and the attached document (F) image.

  As described above, by associating the individual index with the document index, the relationship between the document index and the image data is 1: 1. The relationship between the individual index and the document index is N: 1. That is, even if a single document includes a plurality of indexes, only one image data of the representative form is required. As in the prior art, there is no need to read the representative form again in accordance with the individual index, and the reading efficiency and the storage area utilization efficiency can be improved. Also, in the search, since the individual index that is not described at the top of the representative form is associated with the image data of the document including the incidental form, there is an advantage that the re-search is not necessary and the search efficiency can be improved. is there.

FIG. 9 is a diagram illustrating an example of index management information. (A) shows individual index management information, and (B) shows document index management information.
(A) In the individual index management information 3100, a reference destination document index 3102 is registered in association with the individual index 3101 extracted from the representative form of the target document. For example, in the individual indexes “A”, “B”, and “C” extracted from the application document ABC 511 of the document ABC 510, “INDEX-A” is registered as a reference destination document index. Similarly, “INDEX-D” is registered in “D”, “INDEX-E” is registered in “E”, and “INDEX-F” is registered in “F” as a reference destination document index.

  (B) In the document index management information 3200, reference destination image data 3202 is registered in association with the document index 3201 of the target document. For example, the document index “INDEX-A” is registered to use “application document ABC image” as reference image data. Similarly, “INDEX-D” includes “application document D image”, “INDEX-E” includes “application document E image”, and “INDEX-F” refers to “application document F image”. Registered as data. For example, an address indicating a storage area in which each image data is stored is registered.

  In the example of FIG. 9, the index and the reference destination thereof are managed by the table-type individual index management information and the document index management information, but the present invention is not limited to this. Any expression format may be used as long as the index relationship shown in FIG. 8 can be expressed.

  Next, search processing of image data of the document ABC 510, the document D 520, the document E 530, and the document F 540 stored in the image DB 330 will be described. First, the case where the representative form is a comprehensive form will be described, and then the case where the representative form is a normal form will be described.

  FIG. 10 is a diagram showing search processing when the representative form is a comprehensive form. In the individual index DB 310, individual indexes “A”, “B”, and “C”, each associated with a document index, are registered. In the document index DB 320, a document index “INDEX-A” associated with the image data storage area of the document ABC 510 is registered. In the image DB 330, image data of the document ABC 510 is stored in document units.

  The search unit 150 searches the index based on the specified search keyword, and detects the top address of the storage area in which the image data is stored. In the example of FIG. 10, when the search keyword “A” 1501 is specified, the search unit 150 searches the individual index management information in the individual index DB 310 and detects “A”. Since the individual index “A” is associated with the document index “INDEX-A”, the document index management information in the document index DB 320 is searched, and “application document ABC”, “attached document (A)”, “attachment” The head address of the storage area in which the image data of the document ABC 510 having “Document (B)” and “Attached Document (C)” is stored is detected. The search unit 150 returns the image data 1511 of the document ABC 510 as a response to the search keyword “A” 1501. Thereby, the user can acquire the image data of the application document ABC, which is a representative form, and the image data of the attached document (A) as the material of the designated security number “A”, and can confirm the contents. .

  Next, it is assumed that the search keyword “B” 1502 is designated. The search unit 150 searches the individual index management information in the individual index DB 310 and detects “B”. Since the individual index “B” is associated with the document index “INDEX-A”, the document index management information in the document index DB 320 is searched and “application document ABC”, “attached document (A)”, “attachment” is searched. The head address of the storage area in which the image data of the document ABC 510 having “Document (B)” and “Attached Document (C)” is stored is detected. The search unit 150 returns the image data 1512 of the document ABC as a response to the search keyword “B” 1502. As a result, the user can acquire the image data of the application document ABC, which is a representative form, and the image data of the attached document (B) as the material of the designated security number “B”, and can confirm the contents. .

  FIG. 11 is a diagram showing search processing when the representative form is a normal form. In the individual index DB 310, individual indexes “D” and “E”, each associated with a document index, are registered. Document indexes “INDEX-D” and “INDEX-E” associated with image data are registered in the document index DB 320. The image DB 330 stores document image data in document units.

  In the example of FIG. 11, when the search keyword “D” 1503 is designated, the search unit 150 searches the individual index management information in the individual index DB 310 and detects “D”. Since the individual index “D” is associated with the document index “INDEX-D”, the document index management information in the document index DB 320 is searched, and the document having “application document D” and “attached document (D)” is retrieved. The image data storage area of D is detected. The search unit 150 returns the image data 1513 of the document D520 as a response to the search keyword “D” 1503. As a result, the user can acquire the image data of the application document D, which is a representative form, and the image data of the attached document (D) as the material of the designated security number “D” and confirm the contents. . Similarly, when the search keyword “E” 1504 is designated, the image data 1514 of the document E is returned as a response. As a result, the user can acquire the image data of the application document E, which is a representative form, and the image data of the attached document (E) as the material of the designated security number “E” and confirm the contents. .

  Next, a processing procedure and a document management method of the document management apparatus will be described using a flowchart. First, reading / recognition processing and inspection / registration processing at the time of document registration will be described, and then search processing at the time of document search will be described.

FIG. 12 is a flowchart showing a procedure of reading / recognition processing at the time of document registration of the document management apparatus. The target document is set in the scanner 200, registration is instructed, and processing is started.
[Step S01] The reading unit 110 sequentially reads the document ABC 510, the document D 520, the document E 530, and the document F 540 set in the scanner 200, and the image data of each document, and generates image data.

  [Step S02] The recognizing unit 120 acquires the image data read by the reading unit 110, and determines the type of the form. For example, a form type code or the like described in a predetermined position defined in advance is read to detect the form type.

  [Step S03] The recognizing unit 120 determines whether or not the type of the form detected in Step S02 is a representative form. If it is a representative form, the process proceeds to step S04. If it is not a representative form, the process proceeds to step S07 and no recognition process is performed.

  [Step S04] When the type of the form is a representative form, the recognizing unit 120 determines whether the representative form is a normal form or a comprehensive form. If it is a comprehensive form, the process proceeds to step S05. If it is not a comprehensive form, the process proceeds to step S06.

  [Step S05] When the form type is a representative form and a comprehensive form, the recognition unit 120 performs character recognition processing and extracts all M indexes included in the representative form. For example, a position on image data in which an item to be an index is described in advance is defined, and the image data of the representative form is recognized based on the position definition. Moreover, not all the description columns of the items corresponding to the index are filled. When the character recognition of all specified areas is performed and it is determined that there is no description, it is not included in the index. All indexes thus described are extracted, and the process proceeds to step S07.

  [Step S06] When the type of the form is a representative form and a normal form, the recognizing unit 120 performs a character recognition process and extracts one index included in the representative form. A position on the image data in which items to be indexed are described in advance, and the image data of the representative form is recognized based on the position definition.

  [Step S07] The recognizing unit 120 determines whether or not the recognition process has been completed for the image data of all the documents read in step S01. If it is determined that the process has not been completed, the process proceeds to step S02, and the image data of the next form is recognized. If it is determined that the process has been completed, the process proceeds to a connector A shown in FIG. 13 and an inspection / registration process is performed.

FIG. 13 is a flowchart showing a procedure of inspection / registration processing at the time of document registration of the document management apparatus. After the processing up to the connector A shown in FIG. 12 is executed, the following processing procedure is executed.
[Step S08] The inspection unit 130 displays the image data of the document acquired through the processing up to the previous stage and information such as the extracted index on the display unit 160, and waits for an inspection operation by the operator. When the completion of the operator confirmation is notified, the inspected image data and index are delivered to the registration unit 140, and the process proceeds to the next step.

  [Step S09] The registration unit 140 divides the acquired image data of the document into document units. For example, the form type of the image data is examined in order according to the arrangement order, and the representative form is detected. Then, after the representative form is detected, the document form immediately before the next detected representative form is set as one document unit. Further, if the representative form describes the number of forms included in the document, it may be used to detect a document unit break. Then, using the detected delimiter, the image data is divided into document units.

[Step S <b> 10] The registration unit 140 stores image data of a document divided into document units in the image DB 330.
[Step S11] The registration unit 140 generates a document index for identifying a document, associates it with the address of the storage area of the image data stored in the image DB 330, and registers it in the document index management information. As the document index, a unique value is set for each document unit. For example, a position of image data of a document stored in the image DB 330, a headword characterizing the document extracted from the representative form, and the like are set. The set document index management information is set in the document index DB 320.

  [Step S12] The registration unit 140 generates an individual index based on the index extracted by the recognition unit 120. The individual index is registered in the individual index management information in association with the document index to which each belongs, and is set in the individual index DB 310.

[Step S13] The registration unit 140 determines whether or not the processing of all documents has been completed. If not completed, the process returns to step S10 to perform registration processing for the next document.
The above processing procedure is executed, and an individual index and a document index having the relationship shown in FIG. 8 are generated and used for document image data management.

FIG. 14 is a flowchart showing a document search process procedure of the document management apparatus.
A search instruction is received from the user, and the process is started.
[Step S21] Upon receiving the search instruction, the search unit 150 inputs the specified search keyword together with the search instruction.

  [Step S22] The search unit 150 searches the individual index management information in the individual index DB 310 using the input search keyword. An index matching the word specified as the search keyword is searched, and when it is detected, the document index associated with the index is extracted. When the word specified as the search keyword is not detected, it is determined as not detected.

  [Step S23] The search unit 150 determines whether an individual index corresponding to the designated search keyword is detected as a result of the search of the individual index management information in the individual index DB 310 in step S22. If detected, the process proceeds to step S24. If not detected, the process proceeds to step S27.

  [Step S24] When an individual index is detected, the search unit 150 extracts a document index associated with the individual index. Then, using this document index, the document index management information in the document index DB 320 is searched, and the address of the image DB 330 in which the image data of the document unit associated with the document index is stored is extracted.

  [Step S25] The search unit 150 searches the image DB 330 based on the address where the image data of the target document extracted in step S24 is stored, and reads the image data stored in the corresponding storage area. .

[Step S26] The search unit 150 displays the image data read in step S25 on the display unit 160, and ends the process.
[Step S27] When the individual index matching the input keyword is not detected, the search unit 150 notifies the error by displaying an error screen on the display unit 160, and ends the process.

  By executing the above processing procedure, the image data of the document related to the designated search keyword is displayed on the display unit 160. Further, even when a search keyword including an incidental form is designated, the image data of the incidental form can be displayed on the display unit 160 by one search.

  Next, a second embodiment will be described. In the first embodiment, the individual index extracted from the comprehensive form is associated with the document unit document index, and when the individual index corresponding to each supplementary form is designated, the document unit image data is extracted and displayed. Then. In this way, when image data in units of documents is extracted and displayed on the display unit 160, the contents of the first representative form are confirmed, and then the screen is scrolled to a desired incident form to confirm the incident form. be able to. However, there are cases where it is difficult to find a desired incidental form even if image data for each document is acquired, such as when many indexes are described in a comprehensive form. Therefore, in the second embodiment, at the time of retrieval, the image data of the attached form corresponding to the specified individual index is extracted from the document unit image data, and is displayed together with the representative form.

  Note that the configuration of the processing functions of the document management apparatus in the second embodiment is the same as the components of the first embodiment shown in FIGS. Therefore, functions in the second embodiment will be described using the reference numerals of the components shown in FIGS.

  Registration processing and search processing in the document management apparatus according to the second embodiment will be described. Note that the processing when the representative form is a normal form is the same as that in the first embodiment, and therefore, in the following description, the case where the representative form is a comprehensive form will be described.

  FIG. 15 is a diagram illustrating document registration processing when the representative form of the second embodiment is a comprehensive form. The document ABC550 includes an application document ABC551 that is a comprehensive form, an attached document (A) 552, an attached document (B) 553, and an attached document (C) 554. In the application document ABC551, the number of attached documents corresponding to each security number is described in association with the security numbers “A”, “B”, and “C” as indexes. In the example of FIG. 15, one attached document (A) 552 corresponding to the security number “A”, two attached documents (B) 553 corresponding to the security number “B”, and corresponding to the security number “C”. It is described that one attached document (C) 554 is attached to the application document ABC551.

  The reading unit 110 reads the application document ABC551, the attached document (A) 552, the attached document (B) 553, and the attached document (C) 554 in this order, and generates the image data. The recognizing unit 170 determines the form of the image data read by the reading unit 110, and when the form is a representative form, extracts an index and the number of attached forms corresponding to each index. The number of attached forms is also obtained by extracting image data of a predefined area and performing character recognition on the image data. The number of the index and the accompanying form is obtained by, for example, defining the position of the index on the image data and the position of the number of the accompanying form, and character-recognizing the image data extracted based on the definition. In the example of FIG. 15, the application document ABC551 is recognized as a representative form and a comprehensive form, and M indexes and the number of sheets are extracted. Here, as the recognition information 1701, three individual indexes “A”, “B”, and “C” and the number of attached forms “1”, “2”, and “1” corresponding to each individual index are displayed. Extract. The attached document (A) 552, the attached document (B) 553, and the attached document (C) 554 are discriminated as accompanying documents, and recognition processing is not performed. The image data of each form and the recognition information 1701 are delivered to the inspection unit 130. Since the processing of the inspection unit 130 is the same as that of the first embodiment, description thereof is omitted.

  The registration unit 180 divides the image data into document units, and stores the document unit image data in the image DB 330c. In the example of FIG. 15, the image data 5511 of the application document ABC, the image data 5521 of the attached document (A), the image data 5531 of the attached document (B), and the image data 5541 of the attached document (C) are arranged in this order. Store in the DB 330c. Also, a document index “INDEX-A” relating to the document ABC550 is generated and stored in the index DB 320c. Then, an individual index is generated based on the recognition information 1701 extracted from the application document ABC551. In the example of FIG. 15, “A”, “B”, and “C” extracted by the recognition unit 170 are associated with the document index “INDEX-A” indicating the image data of the document ABC, and the individual index management of the individual index DB 310c is performed. Register for information. At this time, “position” and “number of sheets” are stored in association with the individual index as supplementary form information. “Number of sheets” is a numerical value described in the application document ABC551 obtained by character recognition together with the individual index. “Position” is data indicating the number of the attached form corresponding to the individual index from the representative form based on the “number of sheets”. The position information is obtained by adding the “number of sheets” corresponding to the previous individual index to the “position” of the previous individual index in the form array. For example, the “position” of the attached document (A) 552 following the application document ABC551 is “1” because it is next to the representative form. The position of the attached document (B) 553 to be placed next to the attached document (A) 552 is obtained by adding the number “1” of the attached document (A) 552 to the position “1” of the attached document (A) 552. 2 ”. In this way, the number of sheets from the application document ABC551, which is a representative form, is sequentially calculated for the incidental form corresponding to the individual index, and is associated with the individual index and registered in the individual index management information of the individual index DB 310c.

  FIG. 16 is a diagram illustrating an example of index management information according to the second embodiment. (A) is individual index management information. The document index management information is the same as the document index management information 3200 shown in FIG.

  In the individual index management information 3110, a document index 3112 to be referred to, an attached document position 31133, and the number of attached documents 3114 are registered in association with the individual index 3111 extracted from the representative form of the target document. The reference destination document index 3112 indicates a document associated with the individual index. For example, in the individual indexes “A”, “B”, and “C” extracted from the application document 551 of the document ABC550, “INDEX-A” is registered as a reference destination document index. The attached document position 3113 registers the position of the incidental form corresponding to the individual index from the top representative form of this document, in this case, the number from the representative form. In the number of attached documents 3114, the number of attached forms corresponding to the individual index is registered. For example, for the attached document (B) 553 corresponding to the index “B”, the document index “INDEX-A”, the attached document position “2”, and the number of attached documents “2” are registered.

  In the examples of FIGS. 15 and 16, it is assumed that the number of supplementary forms is described in the representative form. For example, as shown in the table of contents, position information indicating the position of the corresponding supplementary form from the top form. May be described in the representative form in advance. In this case, the position information read by character recognition is registered in the attached document position 313. In addition, position information may be defined separately by an operator or the like.

A search process is performed based on such index management information 3110.
FIG. 17 is a diagram illustrating document search processing when the representative form according to the second embodiment is a comprehensive form. In the individual index DB 310c, individual indexes “A”, “B”, and “C”, each associated with a document index, are registered together with a position (position of attached documents) and a number of sheets (number of attached documents). A document index “INDEX-A” associated with the image data is registered in the document index DB 320c. The image DB 330c stores document image data in document units.

  The search unit 190 searches the index based on the specified search keyword, and detects the top address of the storage area in which the image data is stored. In the example of FIG. 17, when the search keyword “A” 1901 is designated, the search unit 190 searches the individual index management information in the individual index DB 310c and detects the individual index “A”. At this time, “position = 1” and “number of sheets = 1” are also acquired. Since the individual index “A” is associated with the document index “INDEX-A”, the document index DB 320c is searched, and “application document ABC”, “attached document (A)”, “attached document (B)”. And the image data storage area of the document ABC having “attached document (C)” is detected. Based on “position = 1” and “number of sheets = 1” corresponding to the index “A”, the search unit 190 obtains the image data of the attached document (A) corresponding to the index “A” as the representative form. It is specified that it is one document located at the first position from the application document ABC. Then, the image data for the attached document (A) is extracted, image data 1911 combined with the image data of the application document ABC, which is a representative form, is generated, and returned as a response to the search keyword “A” 1901. Thereby, the user can acquire the image data of the application document ABC, which is a representative form, and the image data of the attached document (A) for the specified securities number “A” and confirm the contents. Subsequently, it is assumed that the search keyword “B” 1902 is designated. The search unit 190 searches the individual index management information in the individual index DB 310c and detects the individual index “B”. At this time, “position = 2” and “number of sheets = 2” are also acquired. Since the individual index “B” is associated with the document index “INDEX-A”, the document index DB 320c is searched, and “application document ABC”, “attached document (A)”, “attached document (B)”. And the image data storage area of the document ABC having “attached document (C)” is detected. Further, based on “position = 2” and “number of sheets = 2” corresponding to the index “B”, the image data of the attached document (B) corresponding to the index “B” is a representative form. It is specified that the two documents are in the second position from the document ABC. Then, the image data for the attached document (B) is extracted, image data 1912 combined with the image data of the application document ABC as a representative form is generated, and returned as a response to the search keyword “B” 1902. As a result, the user can acquire the image data of the application document ABC, which is a representative form, and the image data of the attached document (B) as the material of the designated security number “B” and confirm the contents.

  In the second embodiment, the position is calculated based on the number of sheets and registered in association with the individual index during the registration process. However, only the number of sheets is registered, and the position calculation process is a search process. You can also do it.

  According to the second embodiment, for a document whose representative form is a comprehensive form, only the representative form and the incidental form corresponding to the index specified by the search keyword can be selectively extracted. For this reason, it is possible to save the trouble of searching for a desired incidental form from a lot of image data extracted in units of documents, and the search efficiency can be further improved.

  The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the document management apparatus should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic storage device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic storage device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Optical discs include DVD, DVD-RAM, CD-ROM / RW, and the like. Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, a portable recording medium such as a DVD or a CD-ROM in which the program is recorded is sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. In addition, each time a program is transferred from a server computer connected via a network, the computer can sequentially execute processing according to the received program.

  In addition, at least a part of the above processing functions can be realized by an electronic circuit such as a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or a PLD (Programmable Logic Device).
