Description

The present invention relates to a document examination support device, a document examination support method, and a computer program.

Conventionally, in the activities of companies, etc., various activities of companies, etc. are carried out by exchanging documents (contracts, etc.) describing the contents of agreements and transaction conditions and clarifying the status and rights and obligations of the parties. .. Whether the rights and obligations specified in the document meet the purposes of each party, whether the obligations that each party may have are acceptable, and whether they comply with the law. Ka, etc. has a great influence on the activities, profits and disadvantages after exchanging documents. Therefore, careful consideration and examination are required when concluding a document. Such examination is not limited to contracts, but is required each time, for example, in the formulation and approval decision-making of some documents such as application documents such as loans, application documents for public offerings, and in-house approval documents.

Here, the examination can be considered as a process of collating some provisions such as internal rules and contract policies with the contents of the target document and determining the suitability thereof. There was a problem that a certain amount of cost and time was required for collation in the examination because sufficient skills were required. Therefore, conventionally, a support device has been proposed in which even a contract person with little experience or knowledge can easily examine a contract (see, for example, Patent Document 1). With the technology described in Patent Document 1, by presenting the description of the contract related to the examination of the contract contents at the stage of creating the contract, even the person in charge of the contract who lacks experience and knowledge can easily examine the contract. We are helping you to do that.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
(First Embodiment)
FIG. 1 is a schematic block diagram showing a functional configuration of the document examination support device 10 according to the first embodiment.
The document examination support device 10 supports the examination of documents. Here, the document is a document in which the description contents are defined to some extent, such as a contract, an application document for a loan, an application document for a public offering, an in-house approval document, etc., and a description format is defined. Any document may be used as long as it is. In the following description, a contract will be described as an example as a document. The support for document examination performed by the document examination support device 10 means that the customer confirms the content (for example, the content of the article) in the document (for example, the contract), the presence or absence of matters to be described, the description error, and the like. Means support when doing. The document examination support device 10 is configured by using, for example, an information processing device such as an OS, a personal computer, a notebook computer, a smartphone, a mobile phone, or a tablet terminal constructed by VM or container technology.

The document examination support device 10 includes a control unit 11 and a storage unit 12.
The control unit 11 is configured by using a processor such as a CPU (Central Processing Unit) and a memory. By executing the program, the control unit 11 functions as a document input unit 111, a document structuring unit 112, a document evaluation unit 113, a screen data generation unit 114, and a display unit 115.

The document input unit 111 inputs a single or a plurality of documents to be examined. The document input unit 111 may input a document stored in the memory or hard disk of its own device, input a document uploaded to the document examination support device 10, or transmit from another device via a network. The document may be input, the document input by the user may be input, or the document stored in an external recording medium such as a USB (Universal Serial Bus) memory or an SD card may be input. .. In the first embodiment, a case where the document input unit 111 inputs one document to be examined will be described as an example.

The document structuring unit 112 semantically structures the document input to the document input unit 111 according to specific conditions. Specifically, the document structuring unit 112 decomposes the document into a plurality of description units according to specific conditions, and semantically structures each of the plurality of description units after the decomposition.

FIG. 2 is a schematic block diagram showing a detailed functional configuration of the document structuring unit 112 in the first embodiment.
The document structuring unit 112 is composed of a text structuring unit 1121, a document decomposition unit 1122, a specified type determination unit 1123, a specified item determination unit 1124, and a specified location extraction unit 1125.
The text conversion unit 1121 converts the input document into text as necessary based on the input document. If the input document is a text file, the text conversion unit 1121 does not convert the document into text. On the other hand, if the input document is not a text file, the text conversion unit 1121 converts the document into text. When it is not a text file, for example, the document is an image file (for example, a PDF (Portable Document Format) file), a word processor document containing layout information and character decoration information, and an HTML (Hyper Text Markup Language) file. This is the case. If the input file is a word processor document containing layout information and character decoration information, the text conversion unit 1121 converts the document into a text file by removing the layout information and character decoration information. If the input file is an image file, the text conversion unit 1121 converts the document into a text file by OCR (Optical Character Reader).

The document decomposition unit 1122 decomposes the document of the text file output from the text conversion unit 1121 into a certain description unit. For example, when a document is a contract or a contract document, it is generally described in terms of clauses. Therefore, the document decomposition unit 1122 decomposes the document converted into a text file in the unit of clause (description unit). In the case of a document without a clause number, it is conceivable to decompose it into units such as paragraphs and sentences.

The specified type determination unit 1123 determines the type (hereinafter referred to as "specified type") specified for each description unit decomposed by the document decomposition unit 1122. For example, when the document is a contract or a contract document, the prescribed types generally include types such as liability for damages and payment terms. Therefore, when the document is a contract or a contract document, the regulation type determination unit 1123 determines which regulation type such as liability for damages and payment conditions is specified for each description unit. For these specified types, it is necessary to design a system for each type of document to be examined. As a means for determining the specified type by the specified type determination unit 1123, for example, rule determination using keywords included in the document can be considered. It may be realized by machine learning using training data prepared manually.

The specified item determination unit 1124 determines an item (hereinafter referred to as “specified item”) specified by the document for each specified type determined by the specified type determination unit 1123. Here, there are roughly two types of specified items. The first is whether or not a particular provision is stated in the document. For example, if it is a rule item that is stipulated for the rule type "responsibility for damages", an item such as whether or not an exemption rule for ordinary damage is described is applicable. The second is when some value is specified. For example, if it is a rule item that stipulates payment terms, a stipulation regarding payment due date can be considered. Specifically, a value such as "30 days" after acceptance inspection is specified. If it is the first type, it can be realized as a keyword judgment or a judgment by machine learning whether or not the regulation is made. In the second type, numerical information such as "30 days" will be extracted from the document, but as a means of realization, for example, extraction by regular expression rules or extraction by machine learning series labeling can be considered. ..

FIG. 3 is a diagram showing an example of definition data 121 in the first embodiment. The definition data 121 is data in which the structure definition of the semantic structure used in the specified type determination unit 1123 and the specified item determination unit 1124 is registered. The definition data 121 includes a specified type, a specified item, a specified value type, and a possible specified value item. The specified type column shows the types that may be specified in the document to be examined. In the rule item column, items are shown with specific rule contents in each rule type. The default type column and the possible default value column define the possible values for each default item. The default value type column defines the type of value, and in FIG. 3, the enumeration type, the number of days, and the unique name are described as the default value type. An enumeration type is a type defined by enumerating possible values, and the possible values are listed in the "possible default values" column. The number of days is an example of a numerical type, which means that the possible value is the number of days. In addition to the numerical type, the amount of money, the interest rate, the due date, etc. can be considered, and the value can be expressed numerically in general. A unique name means a type of value that a name of an object can take, such as a company name, a person's name, a place name, or a product name. In FIG. 3, an example is described as "unique name", but it is also possible to define detailed classifications such as "company name" and "product name" as default value types.

Taking FIG. 3 as an example, the specified type determination unit 1123 determines which of the "specified types" shown in the definition data 121 corresponds to for each description unit. The specified item determination unit 1124 determines the specified value of each "specified item" for each specified type shown in the definition data 121 according to the description of the "specified value type" and the "possible specified value". The default item determination unit 1124 determines which of the "possible default values" corresponds to if the "default value type" is "enumerated type", and extracts the value from the document text if it is another type. ..

The specified location extraction unit 1125 extracts from the document the location where each specified item determined by the specified item determination unit 1124 is specified. As a method of extraction by the specified location extraction unit 1125, extraction by a regular expression rule, extraction by sequence labeling using machine learning, or the like can be considered. The specified location extraction unit 1125 may extract from the document the location where each specified type determined by the specified type determination unit 1123 is specified. In this way, the specified location extraction unit 1125 extracts the specified portion in the document that describes the contents related to either or both of the specified type and the specified item determined in order to decompose the document into a semantic structure.

The explanation will be continued by returning to FIG.
The document evaluation unit 113 evaluates the document based on the specified type determined by the specified type determination unit 1123, the specified item determined by the specified item determination unit 1124, and the examination rule stored in the storage unit 12.
The screen data generation unit 114 is a screen data for confirming the examination result of the document based on the evaluation result by the document evaluation unit 113 and the specified portion extracted by the specified portion extraction unit 1125 (hereinafter, “evaluation result screen data”). ".) Is generated.

The display unit 115 is an image display device such as a liquid crystal display, an organic EL (Electro Luminescence) display, and a CRT (Cathode Ray Tube) display. The display unit 115 displays the evaluation result screen data. The display unit 115 may be an interface for connecting the image display device to the document examination support device 10. In this case, the display unit 115 generates a video signal for displaying the evaluation result screen data, and outputs the video signal to the image display device connected to the display unit 115.

The storage unit 12 stores the definition data 121 and the examination rule 122. The storage unit 12 may be configured by using a storage device such as a magnetic hard disk device or a semiconductor storage device, may be virtually constructed on an OS constructed by a virtual machine technology, or may be virtually constructed by a container technology. It may be virtually built on the OS to be built.

The definition data 121 is data in which the structure definition of the semantic structure used in the specified type determination unit 1123 and the specified item determination unit 1124 is registered.
The examination rule 122 has a structure shown in, for example, FIG. 4 or FIG. 5, and is a rule for examining a specified item and a specified type in a document. FIG. 4 is a diagram showing an example of examination rules regarding the specified items in the document in the first embodiment. Further, FIG. 5 is a diagram showing an example of examination rules regarding the specified types in the document in the first embodiment. As shown in FIG. 4, the examination rule 122 regarding the specified items defines the values of "specified value condition" and "appropriateness" in each specified item. The "specified value condition" is a condition for determining the suitability of the specified item. For example, as a specified value condition, an individual specified value may be given as in the case of "damage compensation range_normal damage", or a value range may be given as in the case of "payment date_days". It is also conceivable to perform some calculation on the value extracted by the specified value to determine the suitability, as in the example of the specified item "A". In the present embodiment, it is shown that the determination is made based on whether or not the business partner extracted by "A" is already registered in the database as a business partner.

"Appropriateness" is a value indicating whether the value of the specified item is appropriate or inappropriate when any of the "specified value conditions" is satisfied. It can be given as two values, appropriate and unsuitable, but an intermediate value meaning an intermediate risk can be provided, or some score value can be described and given as a continuous value. It is also conceivable to calculate the overall risk score of the document to be examined by accumulating these score values. Furthermore, it is conceivable to prepare a value such as "undecidable" and build a system that encourages individual confirmation by the user.

As shown in FIG. 5, the examination rule 122 regarding the specified type defines the values of "presence / absence condition" and "appropriate / non-appropriate" in each specified type. The "presence / absence condition" is a condition for determining the suitability of the specified type. "Appropriateness" is a value indicating whether the value of the specified type is appropriate or inappropriate when any of the "presence / absence conditions" is satisfied. In the example shown in FIG. 5, it means the examination rule 122 that it is appropriate if the provision type of "responsibility for damages" exists in the document, and if it does not exist, it is rejected.

FIG. 6 is a flowchart showing a processing flow of the document examination support device 10 in the first embodiment.
The document input unit 111 inputs a document (step S101). For example, it is assumed that the document input unit 111 inputs the document shown in FIG. 7. The document input unit 111 outputs the input document to the document structuring unit 112. The text conversion unit 1121 of the document structuring unit 112 determines whether or not the input document is a text file (step S102). If the input document is not a text file (step S102-NO), the text conversion unit 1121 converts the document into a text file (step S103). The text conversion unit 1121 outputs the document converted into a text file to the document decomposition unit 1122.

When the input document is a text file (step S102-YES), the text conversion unit 1121 outputs the input document to the document decomposition unit 1122. The document decomposition unit 1122 decomposes the document converted into a text file by the text conversion unit 1121 into a certain description unit (step S104). FIG. 8 is a diagram showing an example of each description unit decomposed by the document decomposition unit 1122 in the first embodiment. The decomposition number shown in FIG. 8 represents an identification number for identifying each of the decomposed description units. The document decomposition unit 1122 outputs the information of each description unit to the specified type determination unit 1123. The specified type determination unit 1123 determines the type specified for each description unit decomposed by the document decomposition unit 1122 (step S105). Specifically, the regulation type determination unit 1123 determines which of the text in each description unit and the regulation type predetermined in the definition data 121 corresponds to. As described above, the determination may be realized by a rule such as keyword matching, or may be realized by constructing a text classifier by machine learning. Further, it is conceivable that a plurality of contents are described for one description unit, and in that case, a plurality of specified types are given to one description unit. The specified type determination unit 1123 outputs the determination result of the specified type to the specified item determination unit 1124.

The regulation item determination unit 1124 determines the regulation item specified by the document for each regulation type determined by the regulation type determination unit 1123 (step S106). Specifically, the specified item determination unit 1124 determines a specified value for each specified item specified for each specified type. The processing contents are classified into two according to the specified value type in FIG. The first classification is the case where the specified value type is "enumerated type", and in this case, it is determined which of the "possible specified values" corresponds to. As described above, the determination may be realized by a rule such as keyword matching, or may be realized by constructing a text classifier by machine learning. The second classification is when the default value type is other than "enumerated type" such as "days" or "unique name". In this case, the description which is the default value is extracted from the text. In addition to the proper name and the number of days shown in the example, the type for extracting the description from the text can be the amount or percentage, the date, the time, the place, and the like. The specified item determination unit 1124 outputs the determination result of the specified item to the specified location extraction unit 1125.

The specified location extraction unit 1125 extracts from the document the location where each specified item determined by the specified item determination unit 1124 is specified (step S107). Extraction can be done by regular expression rules or by series labeling using machine learning. As the extraction unit, there are cases where characters are extracted as units, words are extracted as units, phrases, clauses, and sentences separated by punctuation marks are extracted as units, and paragraphs are extracted as units. In this example, it is expressed by the character string extracted as the extraction result, but it may be expressed by the character position in the original document.

The input document is structured into a semantic structure as shown in FIG. 9 by the determination result by the specified type determination unit 1123, the specified item determination unit 1124, and the specified location extraction unit 1125. The "specified type" column in FIG. 9 is the output of the specified type determination unit 1123, the "specified item" and "specified value" columns are the output of the specified item determination unit 1124, and the "specified location" column is the specified location extraction unit. It is the output of 1125.

The document evaluation unit 113 evaluates the document based on the specified type determined by the specified type determination unit 1123, the specified item determined by the specified item determination unit 1124, and the examination rule 122 stored in the storage unit 12. (Step S108). Specifically, the document evaluation unit 113 collates the examination rule 122 with the specified type and specified item, and evaluates the document depending on whether or not the specified type and specified item satisfy the examination rule 122. The display unit 115 displays the evaluation result obtained by the document evaluation unit 113 (step S109). The evaluation result may be either the suitability of the specified type and the suitability of the specified item in each description unit, or may be either the suitability of the specified type or the suitability of the specified item. When displaying the evaluation result, the display unit 115 also displays the specified portion extracted by the specified portion extraction unit 1125 in addition to the evaluation result so as to facilitate the user's understanding. It may be configured.

According to the document examination support device 10 configured as described above, even a person in charge of document examination who lacks experience and knowledge can more easily examine a contract. Specifically, the document examination support device 10 decomposes the document to be examined into a semantic structure based on the specified type and the specified item, and evaluates the document by collating the decomposition result with the examination rule 122. And output the evaluation result. In this way, the document examination support device 10 presents the evaluation result of the document to the person in charge of document examination. As a result, the person in charge of document review can easily grasp which part of the document should be confirmed only by looking at the evaluation result of the document. Therefore, even a contractor who lacks experience and knowledge can more easily examine the contract.

Further, conventionally, the part of the document to be examined is presented, and the judgment of suitability is made by human reading comprehension of the document. Therefore, the labor reduction of the person in charge of document review was limited. On the other hand, in the document examination support device 10, the evaluation of the document is automatically performed by the machine. Then, the person in charge of document review needs to refer to the evaluation result and confirm only the necessary part. Therefore, it is not necessary to check all the documents as in the past. Therefore, it is possible to reduce the cost of reading a large amount of documents and reduce reading mistakes.

Further, in the document examination support device 10, it is easy to individually construct a system for each document examination organization by separating the semantically structured part and the examination rule part that do not depend on the examination criteria of each document examination organization. become.

In addition, in the examination of a document, there are many cases where it is sufficient not only to confirm the document but also to judge the consistency with the existing separate agreement document. In such a case, since there are many documents to be read, there is a problem that even a highly skilled person with specialized knowledge requires a great deal of labor in the examination. On the other hand, in the document examination support device 10, the evaluation of the document is automatically performed by the machine. Then, the person in charge of document review needs to refer to the evaluation result and confirm only the necessary part. Therefore, it is not necessary to check all the documents as in the past. Therefore, it is possible to reduce labor even when a highly skilled person with specialized knowledge examines.

<Modified example of the first embodiment>
The document examination support device 10 may be configured to decompose and evaluate a document to be examined into a semantic structure based on either a specified type or a specified item. When the document examination support device 10 decomposes into a semantic structure and evaluates based on the specified type, the document examination support device 10 does not have to include the specified item determination unit 1124. Further, when the document examination support device 10 decomposes into a semantic structure and evaluates based on the specified items, the document examination support device 10 does not have to include the specified type determination unit 1123. Hereinafter, the configuration of each pattern will be described.

First, a case where the document examination support device 10 decomposes into a semantic structure and evaluates based on the specified type will be described. In this case, the document evaluation unit 113 has the specified type of the examination rule 122 shown in FIG. 5 in the document based on the specified type determined by the specified type determination unit 1123 and the examination rule 122 shown in FIG. Judge whether or not. Then, the document evaluation unit 113 evaluates the document based on the presence or absence of the specified type. The evaluation result in this configuration is the suitability for each specified type in each description unit.

Next, a case where the document examination support device 10 decomposes into a semantic structure and evaluates based on the specified items will be described. In this case, the document evaluation unit 113 determines whether or not the specified item satisfies the examination rule 122 shown in FIG. 4 based on the specified item determined by the specified item determination unit 1124 and the examination rule 122 shown in FIG. Is determined. Then, the document evaluation unit 113 evaluates the document based on the specified value condition of the specified item. The evaluation result in this configuration is the suitability of each specified item in each description unit.

(Second embodiment)
In the second embodiment, the process when the document input unit 111 inputs a plurality of documents to be examined will be described.
FIG. 10 is a schematic block diagram showing a functional configuration of the document examination support device 10a according to the second embodiment. The document examination support device 10a includes a control unit 11a and a storage unit 12a.
The control unit 11a is configured by using a processor such as a CPU and a memory. By executing the program, the control unit 11a functions as a document input unit 111, a document structuring unit 112, a document evaluation unit 113a, a screen data generation unit 114, and a display unit 115. The control unit 11a differs from the control unit 11 in that the document evaluation unit 113a is provided in place of the document evaluation unit 113. The control unit 11a is the same as the control unit 11 in other configurations. Therefore, only the configuration of the document evaluation unit 113a will be described.

The document evaluation unit 113a evaluates a plurality of documents based on the specified type determined by the specified type determination unit 1123, the specified item determined by the specified item determination unit 1124, and the examination rule stored in the storage unit 12a. do.

The storage unit 12a stores the definition data 121 and the examination rule 122a. The storage unit 12a may be configured by using a storage device such as a magnetic hard disk device or a semiconductor storage device, may be virtually constructed on an OS constructed by a virtual machine technology, or may be virtually constructed by a container technology. It may be virtually built on the OS to be built. The storage unit 12a stores the examination rule 122a instead of the examination rule 122.

The examination rule 122a has a structure shown in FIG. 11, for example, and is a rule for examining a specified item and a specified type in a document. FIG. 11 is a diagram showing an example of examination rules regarding the specified items in the document in the second embodiment. As shown in FIG. 11, the examination rule 122a regarding the specified items defines the values of "specified value 1 condition", "specified value 2 condition", and "appropriateness" in each specified item. The "specified value 1 condition" and the "specified value 2 condition" are conditions for determining the suitability of the specified item. In the examination rule 122a shown in FIG. 11, the “specified value 1 condition” column corresponds to the semantic structure of the first document, and the “specified value 2 condition” column corresponds to the semantic structure of the second document. Then, it is shown that when both conditions are satisfied, the judgment in the "appropriate" column is made. In the second embodiment, the examination rule when two documents are input is registered as the examination rule 122a, but when three or more documents are input, the number of documents to be input is increased. It is necessary that the corresponding examination rules are registered.

FIG. 12 is a flowchart showing a processing flow of the document examination support device 10a in the second embodiment. In the flowchart shown in FIG. 12, the same processing as that in the flowchart shown in FIG. 6 is designated by the same reference numerals as those in FIG. 6, and the description thereof will be omitted.
The document input unit 111 inputs a document (step S101). For example, it is assumed that the document input unit 111 inputs the second document shown in FIG. 13 in addition to the first document shown in FIG. 7. The document input unit 111 outputs the input first document and second document to the document structuring unit 112. The text conversion unit 1121 of the document structuring unit 112 determines whether or not the input first document and the second document are text files, respectively (step S202). When either or both of the input first document and the second document are not text files (step S202-NO), the text conversion unit 1121 converts the non-text file document into a text file (step S203). The text conversion unit 1121 outputs the first document and the second document to the document decomposition unit 1122.

When both the input first document and the second document are text files (step S202-YES), the text conversion unit 1121 outputs the input first document and the second document to the document decomposition unit 1122. The document decomposition unit 1122, the specified type determination unit 1123, and the specified item determination unit 1124 perform the same processing as in the first embodiment for each document. FIG. 14 is a diagram showing an example after semantic structuring in the second embodiment. The decomposition number shown in FIG. 14 represents an identification number for identifying each of the decomposed description units.

The document evaluation unit 113 evaluates the document based on the specified type determined by the specified type determination unit 1123, the specified item determined by the specified item determination unit 1124, and the examination rule 122 stored in the storage unit 12. (Step S108). The display unit 115 displays the evaluation result obtained by the document evaluation unit 113 (step S205). When displaying, the specified portion extracted by the specified portion extraction unit 1125 may be displayed together to facilitate the understanding of the user. In addition, the display unit 115 may display the information of the description unit having the same specified type in the first document and the second document side by side in addition to displaying the evaluation result. Further, the display unit 115 may display only the information of the description unit having the same specified type in the first document and the second document side by side, separately from the display of the evaluation result.

According to the document examination support device 10a configured as described above, even when a plurality of documents are input, even a contract person with little experience or knowledge can more easily examine the contract. It will be possible.

<Modified example of the second embodiment>
The document examination support device 10a may be configured to decompose and evaluate a plurality of documents to be examined into a semantic structure based on either a specified type or a specified item. When the document examination support device 10a decomposes into a semantic structure and evaluates based on the specified type, the document examination support device 10a does not have to include the specified item determination unit 1124. Further, when the document examination support device 10a decomposes into a semantic structure and evaluates based on the specified items, the document examination support device 10a does not have to include the specified type determination unit 1123.

First, a case where the document examination support device 10a decomposes into a semantic structure and evaluates based on the specified type will be described. In this case, the document evaluation unit 113 has the specified type of the examination rule 122 shown in FIG. 5 in the document based on the specified type determined by the specified type determination unit 1123 and the examination rule 122 shown in FIG. Judge whether or not. Then, the document evaluation unit 113 evaluates the document based on the presence or absence of the specified type. The evaluation result in this configuration is the suitability for each specified type in each description unit.

Next, a case where the document examination support device 10a decomposes into a semantic structure and evaluates based on the specified items will be described. In this case, the document evaluation unit 113 determines whether or not the specified item satisfies the examination rule 122a shown in FIG. 11 based on the specified item determined by the specified item determination unit 1124 and the examination rule 122a shown in FIG. Is determined. Then, the document evaluation unit 113 evaluates the document based on the specified value condition of the specified item. The evaluation result in this configuration is the suitability of each specified item in each description unit.

When the examination rule for some of the specified types is not registered in the examination rule 122a, the document examination support device 10a does not determine the suitability of the specified type not registered in the examination rule 122a, and the specified type is not determined. May be configured to display information of the same description unit side by side on the display unit 115.
In this case, the document reviewer individually evaluates the documents for the specified types that are not registered in the review rule 122a. As a result, although some specified types are evaluated by humans, the labor of the person in charge of document review can be reduced as compared with the case where all documents are evaluated by humans.

<Modification example common to the first embodiment and the second embodiment>
The document examination support devices 10 and 10a may be configured to output the evaluation result to another device. In this case, the document examination support devices 10 and 10a further include an output unit. The output unit outputs the evaluation result to another device. For example, the output unit may output the evaluation result to another device via the network, or may output the evaluation result to a printing device connected to the own device.

The document structuring unit 112 may target the entire document as a target for determination of a specified type, determination of a specified item, and extraction of a specified portion without decomposing the document of the text file into a certain description unit. When configured in this way, the document structuring unit 112 does not have to include the document decomposition unit 1122. Specifically, the text conversion unit 1121 in the document structuring unit 112 outputs the text file of the input document or the converted text file of the input document to the specified type determination unit 1123. The specified type determination unit 1123 determines the type specified by the document output from the text conversion unit 1121. The processing of the specified item determination unit 1124 and the specified location extraction unit 1125 is the same as that of the functional unit having the same name in each of the above-described embodiments.

The document examination support devices 10 and 10a may decompose the document into a plurality of description units before converting the document into a text file by the text conversion unit 1121. In such a configuration, the processing by the document dividing unit 1122 is executed before the processing of the text conversion unit 1121.

The document examination support devices 10 and 10a in the above-described embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read by a computer system and executed. The term "computer system" as used herein includes hardware such as an OS and peripheral devices. Further, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, and a storage device such as a hard disk built in a computer system.

Further, a "computer-readable recording medium" is a communication line for transmitting a program via a network such as the Internet or a communication line such as a telephone line, and dynamically holds the program for a short period of time. It may also include a program that holds a program for a certain period of time, such as a volatile memory inside a computer system that is a server or a client in that case. Further, the above program may be for realizing a part of the above-mentioned functions, and may be further realized for realizing the above-mentioned functions in combination with a program already recorded in the computer system. It may be realized by using a programmable logic device such as FPGA (Field Programmable Gate Array).

Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and includes designs and the like within a range that does not deviate from the gist of the present invention.
