As shown in the example of FIG. 1, the information processing apparatus according to the present embodiment includes a reception module 110, a similar document extraction module 120, a document storage module 130, a document comparison module 140, a template document generation module 150, and a comparison document generation module. 160, a difference detection module 170, and an output module 180.
Documents are text data, and in some cases, electronic data such as images, videos, and audio, or a combination of these, and are subject to storage, editing, search, etc., and are exchanged as individual units between systems or users. What you can do, including things similar to these. Specifically, an electronic document, image data, electronic mail, and the like generated by the document creation software are applicable.
Storage destination information indicating a document storage destination or a document storage destination is also referred to as a folder. Note that the folder is also referred to as a directory depending on the OS (Operating System).

  The reception module 110 is connected to the similar document extraction module 120 and the difference detection module 170. The reception module 110 receives the document 102 and the storage destination folder 104 of the document 102. The document 102 may be stored in the storage folder 104 or stored in the storage folder 104. For example, a case where the document 102 is selected and moved or copied to the storage destination folder 104 based on the operation of the operator with respect to a mouse, a keyboard, a touch panel, or the like is applicable.

  The document storage module 130 is connected to the similar document extraction module 120. The document storage module 130 stores documents and folders as a hierarchical structure. Here, the hierarchical structure will be described. A set of documents (zero or more documents) is stored in a folder. A document, a folder, or a set of documents and folders is stored in the folder. In this way, a hierarchical structure including documents and folders as constituent elements is configured. This is a so-called file system. A folder can be given a name. The contents (document, folder, folder structure) stored in the document storage module 130 are accessed from the similar document extraction module 120.

The similar document extraction module 120 is connected to the reception module 110, the document storage module 130, and the document comparison module 140. The similar document extraction module 120 identifies a folder having a structure similar to the structure including the storage destination folder 104 received by the reception module 110 from the document storage module 130, and a document similar to the document 102 received by the reception module 110. Are extracted from the document stored in the specified folder.
Identify similar documents in two steps.
First, a folder similar to the structure including the storage destination folder 104 is specified. The structure including the storage destination folder 104 refers to the relationship between the storage destination folder 104 and folders related to the storage destination folder 104. A folder related to the storage destination folder 104 is, for example, a parent (upper) folder, a parent folder, a child (lower) folder, a child folder, a sibling folder (for the storage destination folder 104). Other folders having the same parent folder). A similar folder refers to a folder having the same or similar relationship as the relationship between folders related to the storage destination folder 104. For example, a folder having the same name as the storage destination folder 104, a folder having a parent folder having the same name as the parent folder of the storage destination folder 104, and a child folder having the same name as a child folder of the storage destination folder 104 are included. A folder having a name different from the folder 104 by a predetermined number of characters, a folder having a parent folder having a name different from the parent folder of the storage folder 104 by a predetermined number of characters, a storage destination There is a folder having a child folder whose name differs from the child folder of the folder 104 by a predetermined number of characters. The comparison of whether or not they are similar may be performed by comparing path names. Examples of the predetermined number include one character and two characters. Alternatively, similarities may be determined when only a predetermined number of folders in the path name are different.

  Next, a document similar to the document 102 is extracted from the documents stored in the similar folder. For example, a document having the same name as the document 102, a document having a name different from the document 102 by a predetermined number of characters, a document having the same content as the content of the document 102, and the content of the document 102 being different by a predetermined number of characters. There are a document of contents, a document having the same attribute as the attribute of the document 102, a document having an attribute different from the attribute of the document 102 by a predetermined number of characters, and the like. As the predetermined number, for example, in the case of the content of a document, it may be determined according to the capacity of the document.

The document comparison module 140 and the template document generation module 150 analyze a plurality of similar documents extracted by the similar document extraction module 120 and generate a template document that is a document that becomes a template (hereinafter also referred to as a template). The analysis here refers to extracting a part corresponding to the attribute of the document, the same part among a plurality of documents, and a different part.
The document comparison module 140 is connected to the similar document extraction module 120 and the template document generation module 150. The document comparison module 140, for the similar document extracted by the similar document extraction module 120, (1) a part corresponding to an attribute related to the similar document in the similar document, (2) the same part among a plurality of similar documents, (3) Extract any one or more of different parts between a plurality of similar documents.

Hereinafter, these parts will be described.
(1) About a portion corresponding to an attribute related to the similar document in the similar document The attributes related to the similar document are the attribute of the similar document, the attribute of the folder storing the similar document, and the attribute of the folder related to the folder. There is. For example, if the person-in-charge name is described in a similar document and is the same as “store” as the attribute of the similar document, this corresponds to (1). Further, if the destination name is described in the similar document and the folder name is the same as the folder two above the folder storing the similar document, this corresponds to (1).
(2) Compare a plurality of similar documents extracted by the similar document extraction module 120 with respect to the same part among a plurality of similar documents. Compare the contents and extract the same part. For example, if the titles in similar documents are the same, this corresponds to (2). Note that (1) is extracted first. If it is the same part among a plurality of similar documents but is also a part corresponding to (1), it is extracted as a part corresponding to (1).
(3) Differences between a plurality of similar documents A plurality of similar documents extracted by the similar document extraction module 120 are compared. Compare the contents and extract different parts. Although it is a similar document, there is a description specific to the document. These descriptions correspond to (3).

The template document generation module 150 is connected to the document comparison module 140 and the comparison document generation module 160. The template document generation module 150 generates a template document using the portion extracted by the document comparison module 140.
The template document generation module 150 may generate a rule using the attribute for the portion corresponding to the attribute related to the similar document in the similar document and incorporate the rule in the template document. In the above-described example, the rule using an attribute is a rule indicating an area in which “store” as an attribute is described. Further, this is a rule indicating that this is an area in which “name of folder two folders above a document is stored” as an attribute is described. The application of the rules will be described in the description of the comparison document generation module 160. Also, the incorporation of the rule into the template document means that the rule can be applied when a comparison document is generated from the template document. The rules themselves may be stored in the template document, or they may be stored anywhere as long as they can be accessed when generating a comparison document from the template document.
The template document generation module 150 may use the same part in the template document for the same part among a plurality of similar documents. That is, the same portion among a plurality of similar documents is used as it is in the template document.
The template document generation module 150 may make portions that are different among a plurality of similar documents not to be compared in the template document. In other words, the part that is different between multiple similar documents is an area where the uniqueness of the document is described. Therefore, in the comparison document, even if it is compared with the target document, it should not be the comparison target. is there. The free description column mentioned later corresponds.

The comparison document generation module 160 is connected to the template document generation module 150 and the difference detection module 170. The comparison document generation module 160 generates a comparison document that is a document for comparison with the document 102 received by the reception module 110 based on the template document generated by the template document generation module 150. That is, in order to determine whether the document 102 is a document suitable as a document stored in the storage destination folder 104, a document (comparison document) for comparison with the document 102 is generated from the template document.
Specifically, the comparison document is generated by applying the rules in the template document. When the rule is applied, an attribute related to the document 102 is used. Applying this rule means that, in the above example, in the case of a rule indicating that “storage” as an attribute is an area in which the attribute is described, the character string “storage” that is the attribute of the document 102 is set to that area. It is to describe in. Note that the attribute relating to the document 102 includes the attribute of the storage destination folder 104 and the attribute of the folder related to the storage destination folder 104. Applying the rule in this case means that, in the above example, in the case of the rule indicating that the attribute is “the folder name two folders above the folder storing the document”, the storage destination The folder name two above the folder 104 is described in the area.

  The difference detection module 170 is connected to the reception module 110, the comparison document generation module 160, and the output module 180. The difference detection module 170 extracts the difference by comparing the comparison document generated by the comparison document generation module 160 with the document 102 received by the reception module 110. That is, the comparison document is a document suitable as a document stored in the storage destination folder 104 (a document generated from a similar document or the like in a folder similar to the storage destination folder 104 that is an already created document or the like). Therefore, by comparing this with the document 102 and extracting the difference, the difference portion is extracted as a portion of the document 102 with a possibility of an error.

  The output module 180 is connected to the difference detection module 170. The output module 180 outputs the difference extracted by the difference detection module 170 as a possible error portion of the document 102. Here, outputting the difference may output a portion having a difference in the document 102 in a form (color, shape, pattern, output method, or a combination thereof) different from other portions. For example, when the document 102 is displayed, the part is displayed in red, surrounded by a rectangle, displayed with a pattern on the background, or blinked. For output, when an output target is an image, for example, printing with a printing device such as a printer, displaying on a display device such as a display, transmitting an image with an image transmission device such as a fax, For example, a document image including difference information may be written in an image storage device such as a database. In addition, a document including difference information as an output target (for example, a document in which difference information is additionally written, or information including a difference information and a link to the document) To store in a storage medium such as a hard disk device or a memory card, to write a document including difference information into a document storage device such as a document database, or to other information processing devices (for example, for notification of notification of differences) May be a program).

FIG. 2 is a flowchart showing an example of processing according to this embodiment.
In step S202, the reception module 110 receives the document A1 and the storage destination folder B.
For example, the document storage module 130 stores a document group having a folder structure illustrated in FIG. This file is created for an estimate job, and files are classified for each destination company. A folder for each job such as estimate, approval, ordering, and delivery is configured for each estimate number. A document used or used in the business is stored in a folder for each business. Specifically, the estimation business folder 300 includes a company A folder 302, a company B folder 348, a company C folder 358, and a company D folder 360. The company A folder 302 includes an estimate 0001 folder 304 and an estimate 0003 folder 338. The estimate 0001 folder 304 includes an estimate folder 306, an approval folder 312, an order folder 318, and a delivery folder 322. The estimate folder 306 includes an estimate 308 and an estimate answer 310. The approval folder 312 includes an approval request document 314 and an approval document 316. The order folder 318 includes an order form 320. The delivery folder 322 has a delivery note 324. The estimate 0002 folder 326 includes an estimate folder 328, an approval folder 334, and an order folder 336. The estimate folder 328 includes an estimate form 330 and an estimate answer form 332. The estimate 0003 folder 338 includes an estimate folder 340, an approval folder 342, an order folder 344, and a delivery folder 346. The B company folder 348 includes an estimate 0101 folder 350, an estimate 0102 folder 352, an estimate 0103 folder 354, and an estimate 0104 folder 356.
In such a folder structure, when the document 400 is to be stored (or stored) in the estimated folder 340 as the storage destination folder B according to the operation of the operator, The estimate folder 340 is received. FIG. 4 is an explanatory diagram showing an example of the document 400, the document attribute 410 of the document 400, and the folder attribute 420 of the document 400 (an example of the attribute of the storage destination folder). The folder attribute 420 is a path name when the document 400 is stored in the estimated folder 340.

In step S <b> 204, the similar document extraction module 120 extracts a folder B <b> 2 having a folder structure similar to the folder structure constituted by the folders related to the storage destination folder B <b> 1 from the document storage module 130.
In the above example, the estimated folder 306 and the estimated folder 328 are extracted as the folder B having a folder structure similar to the estimated folder 340. When only one folder name in the path name is different (the estimated 0001 folder 304 and the estimated 0002 folder 326 are different from the estimated 0003 folder 338 in the path name), it is extracted as a similar folder. For example, in order to determine whether the path names are similar, the similar case may be determined in advance using a regular expression or the like.

In step S206, the similar document extraction module 120 extracts a document A2 similar to the document A1 from the extracted folder B2 from the document storage module 130.
In the above example, the estimate 308 and the estimate 330 are extracted as the document A 2 similar to the document 400 from the documents in the estimate folder 306 and the estimate folder 328. The content of the estimate 308 is a document 500. The content of the estimate 330 is a document 600. FIG. 5 is an explanatory diagram illustrating an example of the document 500, the document attribute 510 of the document 500, and the folder attribute 520 of the document 500 (an example of an attribute of a storage destination folder). FIG. 6 is an explanatory diagram illustrating an example of the document 600, the document attribute 610 of the document 600, and the folder attribute 620 of the document 600 (an example of the attribute of the storage destination folder). The document name and contents of the document 400 are compared with the document names and contents of the document 500 and the document 600, and it is determined that the different parts are smaller than a predetermined ratio. ing.

In step S208, the document comparison module 140 may be conditional on (1) a portion corresponding to the attribute related to the document A2 (a plurality of documents A2 have the same correspondence) with respect to the extracted documents A2. ), (2) Extract the same part between the plurality of documents A2, and (3) Extract the different part between the plurality of documents A2.
Using the above example, the comparison result / template document 700 shows an example of the result of comparing the document 500 and the document 600. FIG. 7 is an explanatory diagram showing an example of the comparison result / template document 700. The comparison result / template document 700 includes areas 710 to 730. These areas are punctuation marks, line feed codes, symbols (for example, “:”, etc.), fields, tags in the case of structured documents, etc., or the results of segmentation. The process of step S208 is performed for each area.
As “(1) portion corresponding to the attribute related to the document A 2”, an area 712, an area 722, an area 728, and an area 730 are extracted. An area 712 corresponds to a folder name (Company A folder 302) two above the storage folder (estimate folder 306, estimate folder 328). The area 722 corresponds to the folder name (estimated 0001 folder 304, estimated 0002 folder 326) one above the storage folder (estimated folder 306, estimated folder 328). An area 728 corresponds to the attribute “store”. The area 730 corresponds to the attribute “storage date”.
As “(2) the same part among a plurality of documents A2,” an area 710, an area 714, an area 716, an area 720, an area 724, and an area 726 are extracted.
The region 718 is extracted as “(3) a portion that differs among the plurality of documents A2”.
Note that the extraction target of the parts (1), (2), and (3) is not limited to the text in the document. In the case of an image, the character recognition result, the character size, the character color, and the like for the image may be included. Good. For example, when comparing (2) and (3) between a plurality of documents in order to extract the same part, the comparison including not only the text but also the character size, character color, etc. You may make it extract.

In step S210, the template document generation module 150 performs the following processing on the part extracted in step S208 to generate a template document. (A) A rule using an attribute is generated for the part (1), the part (B) (2) is used as it is, the part (C) (3) is free It is a description part.
As an example of the generated template document, a comparison result / template document 700 is shown. FIG. 7 is an explanatory diagram showing an example of the comparison result / template document 700. The comparison result / template document 700 includes areas 710 to 730. A template table 800 is generated as a processing result of step S210 for each area. Then, the template table 800 is incorporated into the comparison result / template document 700. FIG. 8 is an explanatory diagram showing an example of the data structure of the template table 800. The template table 800 has an ID column 810, an area column 820, and a rule column 830. The ID column 810 stores a code that uniquely identifies an area in the present embodiment. The area column 820 stores the position of the area. The area column 820 includes an X column 822, a Y column 824, a W column 826, and an H column 828. The X column 822 stores the X coordinate of the upper left coordinate of the area. The Y column 824 stores the Y coordinate of the upper left coordinate of the area. The W column 826 stores the width of the area. The H column 828 stores the height of the area. The rule column 830 stores a rule applied to the area. Note that although the position is specified by the coordinates in the document as the area column 820, it may be a field or a tag in the case of a structured document as long as the position in the document can be specified.

In step S212, the comparison document generation module 160 applies the attribute related to the document A1 to the template document and generates a comparison document.
Using the above example, the comparison document 900 is an example of a result of applying the template table 800 incorporated in the comparison result / template document 700 to the document 400. FIG. 9 is an explanatory diagram illustrating an example of the comparison document 900. The comparison document 900 has an area 912, an area 918, an area 922, an area 928, and an area 930. An area 912 uses a folder name (Company A folder 302) two above the storage folder (estimate folder 340). An area 918 is a free description column. The area 922 uses a folder name (estimated 0003 folder 338) that is one above the storage folder (estimated folder 340). An area 928 uses “store” in the document attribute 410 of the document 400. An area 930 uses the “storage date” in the document attribute 410 of the document 400.

In step S214, the difference detection module 170 compares the document A1 with the comparison document and detects a difference portion.
Using the above example, the document 400 and the comparison document 900 are compared. The difference portion is an area 922 when represented by the comparison document 900, and the corresponding portion of the document 400 is “estimation 0005”, but the comparison document 900 is “estimation 0003”. Note that the area 918 is not a comparison target with the document 400.
In step S216, the output module 180 outputs the difference portion as a portion having a possibility of error.
Using the above example, the difference portion between the document 400 and the comparison document 900 is output as in the example of the difference display document 1000. FIG. 10 is an explanatory diagram illustrating an example of the difference display document 1000. The difference display document 1000 has an area 1022. It is pointed out that the area 1022 is a different part and there is a possibility of an error (the request number is estimated 0005 even though it is stored in the estimated 0003 folder 338 or stored).

Among the above-described embodiments, the computer program is a computer program that reads the computer program, which is software, in the hardware configuration system, and the software and hardware resources cooperate with each other. Is realized.
Note that the hardware configuration illustrated in FIG. 11 illustrates one configuration example, and the present embodiment is not limited to the configuration illustrated in FIG. 11, and is a configuration capable of executing the modules described in the present embodiment. I just need it. For example, some modules may be configured by dedicated hardware (for example, ASIC), and some modules may be in an external system and connected via a communication line. A plurality of systems shown in FIG. 5 may be connected to each other via communication lines so as to cooperate with each other. In particular, in addition to personal computers, information appliances, copiers, fax machines, scanners, printers, and multifunction machines (image processing apparatuses having two or more functions of scanners, printers, copiers, fax machines, etc.) Etc. may be incorporated.

  In the above embodiment, two documents are extracted as similar documents and a template document is generated. However, three or more similar documents may be extracted. The document comparison module 140 uses the probability to “(1) a portion corresponding to an attribute related to the similar document in the similar document”, “(2) the same portion among a plurality of similar documents”, “(3) a plurality of The “parts that differ between similar documents” may be extracted. For example, for the first line of a document, four of the five documents are the same, but when one is different, the first line of the four documents is adopted with a probability of 80% (the ratio of being the same). This may be included in the extraction result. The template document generation module 150 includes the probability in the rule (rule field 830 of the template table 800), the comparison document generation module 160 includes the probability in the area, and the difference detection module 170 adds the probability to the comparison result. It may be included. Then, the output module 180 may output so as to point out that there is a possibility of an error at that probability. In the above example, if the first line of the target document is different from the comparison document, the first line of the target document is incorrect with a probability of 80%, and the first line of the comparison document (four It may be output by pointing out that the possibility of being in the first line of the document is 80%. Similarly, in the case of four or more similar documents, if the part that matches the attribute “storage date” with a probability of 50% is incorrect, “50% of similar documents are stored on the Xth line. "Please check the contents." In the case of two similar documents, since the probability of 50% is different, it is extracted not as the same part but as a different part. The probability may be used when three or more similar documents are extracted.

The program described above may be provided by being stored in a recording medium, or the program may be provided by communication means. In that case, for example, the above-described program may be regarded as an invention of a “computer-readable recording medium recording the program”.
The “computer-readable recording medium on which a program is recorded” refers to a computer-readable recording medium on which a program is recorded, which is used for program installation, execution, program distribution, and the like.
The recording medium is, for example, a digital versatile disc (DVD), which is a standard established by the DVD Forum, such as “DVD-R, DVD-RW, DVD-RAM,” and DVD + RW. Standard “DVD + R, DVD + RW, etc.”, compact disc (CD), read-only memory (CD-ROM), CD recordable (CD-R), CD rewritable (CD-RW), Blu-ray disc ( Blu-ray Disc (registered trademark), magneto-optical disk (MO), flexible disk (FD), magnetic tape, hard disk, read-only memory (ROM), electrically erasable and rewritable read-only memory (EEPROM (registered trademark)) )), Flash memory, Random access memory (RAM) Etc. are included.
