Description

  The present invention relates to a document examination support apparatus, a document examination support method, and a program related to a contract.

In business involving transactions, contracts that describe the terms and conditions of each other are important documents that function as evidence when a contract is concluded, and the creation of contracts is a very important business. In general, for example, when a contract is made between a company A and a company B, the contract is created according to the following flow.
Task 1: Company A requests that Company B present a contract according to the content of the contract.
Work 2: Company B creates a contract according to the content of the contract and presents it to Company A.
Work 3: Company A confirms the contents of the contract described in the contract presented by Company B, and presents a proposed change to Company B if correction is necessary.
Thereafter, steps 2 and 3 are repeated until both companies agree on the contract. In the second and subsequent operations 3, the company A compares the contract of the proposed change with the contract created by the company B and confirms the changed part. Further, in the second and subsequent operations 2, Company B compares the submitted contract with the contract of the proposed change revised by Company A, and confirms the changed portion.

  In creating the contract as described above, for example, various techniques as shown in Patent Document 1 and Patent Document 2 have been devised. Patent Document 1 discloses a technique for easily creating an appropriate contract according to contract contents. Specifically, when creating a contract document, all contract patterns (template contracts / self-form clauses) that are assumed in advance for each type of contract (contract type) are prepared and inherent in the transaction. A system for displaying a list of items to be included in a contract document to avoid risks as a checklist and automatically aligning the order of clauses and citations to create a contract document without omissions or deficiencies is disclosed. Yes.

Further, Patent Document 2 prevents the contract document from being changed except for the change of the contract document by repeating the above-described operations 2 and 3, that is, the contract document is prevented from being altered after both parties agree on the contract content. Techniques for disclosing are disclosed.
Specifically, a contract support service method and a contract support system are disclosed that prevent unauthorized tampering in the procedure for signing a contract, enable reliable negotiation of the contract negotiation process, and appropriately support contract work. Yes. In the patent document 2, the falsification prevention and the proof of the negotiation process are based on an aspect in which information indicating the contract clauses before and after the signing can be specified and the date and time of the execution can be specified when signing the contract. Realized by recording.

  However, in the conclusion of the actual contract, based on the contract presented by either one, the contract conditions will be narrowed down while discussing each other and presenting the proposed contract changes to each other. . Therefore, instead of just picking up the best contract terms for the company and negotiating with the other party, it is possible to grasp what conditions have been changed in the proposed change that the other party has modified, and It is necessary to conduct a study focusing on the points to be noted. In addition, when accepting the other party's proposal for change, it is necessary to make a judgment after recognizing the risk caused by the change of conditions.

  However, in general, there are points to be noted in the modified contract, which part should be considered, and what risks are posed by changes in the contract by the other party. It is a situation in which it is necessary to rely on the experience and knowledge of the person in charge to determine whether or not the contract terms of the other party are acceptable.

  In addition, in the company, the review of contract details is often performed by a reviewer who is different from the contractor, so the reviewer cannot ascertain whether the risk is being dealt with reliably. There is a problem that the contract may be advanced without sufficient examination of the contract contents changed by the other party. In other words, the examiner points out potential risk points based on the contents of the contract that he or she understands, but responds to subsequent risks (for example, whether to present a proposal to change the contract contents to the other party or avoid the risk) Whether to take measures or accept the contents of the contract, for example, is performed by the contract person on the basis of the opinion requested of the expert such as the contract supervisor. For this reason, if the person in charge of review cannot fully understand how to deal with the identified risk, for example, a new risk has occurred due to measures to avoid the risk identified at the beginning. It will not be fully examined.

  The technique described in Patent Document 1 prepares all contract patterns assumed in advance, and displays a check list based on a model contract selected from the contract patterns. However, in an actual contract, the contract is not made based on the template contract prepared by the company in advance, and the contract may proceed based on the contract prepared by the other party. It does not provide technology that supports the situation.

  Moreover, although the technique of patent document 2 supports the grasping | ascertainment of the tampering of the contract made after contract conclusion, it does not provide the technique for grasping the change of the contract content at the time of contract preparation.

  In the contract data registration process (step S100), when the data of the contract to be examined is sent from the user, the user who sent the data of the contract has the authority to use the document examination support apparatus 10. This is a process of storing the contract data in the contract data storage unit 120 when it is determined whether or not there is an authority to use the document examination support apparatus 10. In addition, when there is no authority to use the document examination support apparatus 10, a process of sending back to the user that there is no authority to use is performed. The registration process of the contract data is performed by the user interface unit 150 and the text registration unit 160, and detailed processing will be described later.

  The contract text automatic dividing process (step S200) divides the text data of the contract data stored in the contract data storage unit 120, and data relating to the titles of clauses and the clause numbers included in the contracts. Is extracted and stored in the contract document data storage unit 120. Note that the automatic text document splitting process is performed by the attribute tag assigning unit 171 and the information extracting unit 172 in the text splitting unit 170, and detailed processing will be described later.

  The examination item automatic acquisition process (step S300) obtains examination item data corresponding to the title of the clause stored in the contract data storage unit 120 from the examination item data storage unit 130, and based on the obtained examination item data. In this process, the risk included in the contract data is presented to the user. The screening item automatic acquisition process is mainly performed by the screening item acquisition unit 180, and the presentation of risk to the user is performed by the display screen generation unit 200. Detailed processing will be described later.

  Based on the examination item data stored in the examination item data storage unit 130, the examination item corresponding clause search processing (step S400) is performed based on the words included in the contract document data stored in the contract document data storage unit 120. Is a process of searching for data of clauses (clauses to be referred to when the user answers) and presenting data of clauses related to the risk presented to the user in the automatic acquisition process of examination items. In addition, the risk presented to the user in the process for automatically obtaining the screening items, the data of the clause presented to the user in the search processing for the screening items corresponding to the screening items, and the response from the user to the presented risk are created as a checklist and the screening item data The process which memorize | stores in the memory | storage part 130 is also performed. The search process for the examination item corresponding clause is mainly performed by the search keyword generation unit 191 and the corresponding clause search unit 192 in the examination item corresponding clause search unit 190, and presents the clause data to the user and generates the check list. Is performed by the display screen generation unit 200, and detailed processing will be described later.

  Next, the user interface unit 150, the text registration unit 160, the text division unit 170 (the attribute tag addition unit 171 and the information extraction unit 172), the examination item acquisition unit 180, the examination item corresponding clause search unit 190 (the search keyword generation unit 191 and The function of the corresponding clause search unit 192), the display screen generation unit 200, and the details of processing will be described. FIG. 6 is a flowchart showing details of the processing procedure of the document examination support apparatus 10 according to the present embodiment. 6A is a flowchart showing the processing procedure of the automatic document text division processing, FIG. 6B is a flowchart showing the processing procedure of the examination item automatic acquisition processing, and FIG. 6C. These are the flowcharts which showed the process sequence of the search process of examination item corresponding | compatible clauses.

  FIG. 7 is an example of a registration screen for inputting contract data. FIG. 8 is an example of an output screen for presenting the examination result in the contract to be examined to the user. 9, 10 and 11 are explanatory diagrams for explaining the operations of the attribute tag assigning unit 171 and the information extracting unit 172. 12 and 13 are explanatory diagrams for explaining the operation of the examination item acquisition unit 180. FIGS. 14, 15, and 16 are explanatory diagrams for explaining operations of the search keyword generation unit 191 and the corresponding clause search unit 192.

First, step S100 shown in FIG. 5A will be described.
The user interface unit 150 receives the contract data to be examined sent from the application program 30 of the user terminal via the network 20. The contract data includes, for example, user terminal information and user information. The user interface unit 150 refers to the user data table 101 based on the received user information, and determines whether or not the user who has transmitted the contract data has the authority to use the document examination support apparatus 10.
Whether or not the user has the authority to use the document examination support apparatus 10 is determined by, for example, whether the user ID included in the contract data is stored in the item “user ID” of the user data table 101. This is done by comparing whether or not. If the user ID included in the contract document data is stored in the item “user ID” of the user data table 101 as a result of the comparison, the user who has sent the contract document data is notified by the document examination support apparatus 10. If the user ID included in the contract data is not stored in the item “user ID” of the user data table 101, the user who sent the contract data It is determined that there is no authority to use the document examination support apparatus 10.

  If the user interface unit 150 determines that the user who has transmitted the contract data has the authority to use the document examination support apparatus 10, the user interface unit 150 outputs the received contract document data to the text registration unit 160. In addition, when the user who has transmitted the contract data is not authorized to use the document examination support apparatus 10, the user interface unit 150 transmits information indicating that the user is not authorized to use the application program 30 via the network 20. Send to. As a result, for example, the application program 30 can present to the user a message or the like for notifying that the user has no authority to use the document examination support apparatus 10 and that the system administrator needs to request registration.

  Also, the user interface unit 150 transmits the display screen data created by the display screen creation unit 200 to the application program 30 via the network 20, and displays the display screen data sent from the application program 30 via the network 20. The input data is output to the text registration unit 160 or the display screen creation unit 200.

For example, when registering contract document data, the user interface unit 150 displays data on the contract document registration screen 100a as shown in FIG. 7 when there is a request for starting the document examination support apparatus 10 from the application program 30 of the user terminal. Obtained from the screen generator 200 and transmitted to the application program 30. The application program 30 displays the received data on the contract registration screen 100a on the display unit of the user terminal. The user inputs the contract data on the contract registration screen 100a displayed on the user terminal by, for example, the following method. For example, the contract data can be input by inputting the text data of the contract in the text input field 111a in the contract registration list 110a of the contract registration screen 100a shown in FIG. 7, or in the contract file selection list 112a. Information on the location where the contract document file is stored is input, and the registration button 113a is operated (for example, clicked with a mouse).
As a result, data (contract data in this example) input to the contract registration screen 100a can be transmitted to the document examination support device 10, that is, the user interface unit 150. The data transmitted to the user interface unit 150 includes, for example, user terminal information and user information. The user interface unit 150 receives the user terminal information and the user information. The contracted document data is output to the text registration unit 160.

  Further, for example, when the result processed by the document review support apparatus 10 is presented to the user, the user interface unit 150 acquires data of the review screen 200a as illustrated in FIG. The application program 30 displays the data of the examination screen 200a on the display unit of the user terminal. When the user inputs a countermeasure based on the examination result on the examination screen 200a displayed on the user terminal, the content of the user's countermeasure is transmitted to the document examination support apparatus 10. The examination screen 200a will be described later.

The text registration unit 160 stores the input contract data in the contract data table 121 in the contract data storage unit 120 based on the user terminal information input from the user interface unit 150 and the user information. . In this embodiment, the information stored in the contract data table 121 by the text registration unit 160 is contract data such as the items “document ID”, “registered user”, and “contract name” shown in FIG. Information indicating the type of the text and text data of the item “body”.
In addition, the text registration unit 160 notifies the attribute tag adding unit 171 of information indicating that the contract data is stored in the contract data table 121.

  When the text registration unit 160 notifies the attribute tag assignment unit 171 of information indicating that the contract data has been stored, automatic contract text division processing (see FIG. 6A) is started.

  When the information indicating that the contract data is stored in the contract data table 121 is input from the text registration unit 160, the attribute tag assigning unit 171 reads the item from the contract data table 121 in the contract data storage unit 120. The text data of “body” is acquired, and an attribute tag is assigned to the acquired text data. Further, the attribute tag assigning unit 171 outputs data obtained by adding an attribute tag to the text data (hereinafter referred to as “text data with attribute tag”) to the information extracting unit 172 (step S210).

Hereinafter, attribute tag assignment in the attribute tag assignment unit 171 will be described in detail.
The attribute tag assigning unit 171 assigns an attribute tag to the text data of the item “body” according to a regular expression defined in advance. More specifically, the attribute tag assignment unit 171 obtains data such as a chapter number, chapter title, article number, article title, item title, item title, and issue number that match the regular expression from the text data of the item “body”. The text data with the attribute tag extracted and provided with the attribute tag is output to the information extraction unit 172.

  For example, when extracting the data of the article number and the article title from the text data “Article 6 (Liability Guarantee)” of a certain item “Body”, the attribute tag assigning unit 171 uses the regular expression [^ ”number” ¥ d ”. <ZYOU_NUM> for the part that matches the "No." d "article" and the part that matches "(". + ")" In the character string that matches the article "" (". +") "] <ZYOU_TITLE> is added, and the text data with attribute tag “<ZYOU_NUM> Article 6 </ ZYOU_NUM> <ZYOU_TITLE> (dealing liability) </ ZYOU_TITLE>” is output.

In other words, an example of the rules regarding attribute tag assignment is as follows.
(Rule 1): A character string at the beginning of a sentence and enclosed in parentheses is given a <TITLE> tag to represent the title of the clause.
(Rule 2): A <ZYOU_NUM> tag is assigned to the number between “No.” and “Article” at the beginning of the sentence to indicate the article number.
(Rule 3): A number at the beginning of a sentence followed by a blank is given a <KOU_NUM> tag to indicate an item number.
(Rule 4): “Previous item”, “Article XX”, “Article XX item”, and “Article XX” in the sentence are attached with a <REFER> tag to indicate a reference to other terms.
(Rule 5): The “XX method” in the sentence is attached with a <REFER> tag to indicate a reference to other information.

  The attribute tag as shown in FIG. 9 (b) in which the attribute tag is added to the text data of the article of “Article 7 (benefit completed)” as shown in FIG. 9 (a) by the above processing. Output body data with text.

The information extraction unit 172 determines how to arrange the clauses of the contract data (clause structure) based on the sequence of the attribute tags attached to the text data with attribute tags input from the attribute tag addition unit 171 (step S220). .
It should be noted that the clause structure by the information extraction unit 172 is determined by the chapter number, chapter title, clause number, clause title, paragraph number, paragraph title, and issue number that match the regular expression even if the clause format is different. This is a pre-stage process for appropriately extracting data such as text.

Hereinafter, the discrimination of the clause structure in the information extraction unit 172 will be described in detail.
For example, when the information extraction unit 172 determines the clause structure in the text data “Article 6 (Redistribution and License for Use of Target Product)” of an item “Body” shown in FIG. A keyword (for example, a number at the beginning of a sentence or a character string surrounded by ()) is extracted from the text data. And for the extracted keyword, it is set in advance based on knowledge about the clause structure of the contract (for example, the clause title is before and after the clause number, the item number of the first term may be omitted, etc.) A pattern that matches the text data of the item “body” is estimated from the clause structure pattern.

An example of the estimation algorithm in the estimation of the clause structure pattern is as follows.
(1): It is a serial number. This utilizes the fact that the article numbers do not overlap, such as “Article 1”, “Article 2”, and so on.
(2): It is a serial number, and a number that is duplicated and used a lot represents an item number. This is based on the fact that there are duplicate item numbers such as “Article 1 Clause 1”, “Article 2 Clause 1”, etc., and they are used in large numbers because they are used in each article.
(3): Article title is before or after article number.

  Through the above processing, the clause structure is determined from the clause of “Article 6 (Redistribution and License for Use of Target Product)” as shown in FIG. 10 (a), and as shown in FIG. 10 (b). The first candidate (pattern 6) is selected.

  The information extraction unit 172 also includes a chapter number, a chapter title, a section number, a section title, a section number included in the text data of the item “body” based on the attribute tag included in the body data with the attribute tag and the determined section structure. Data obtained by dividing the text data of the item “body” (hereinafter referred to as “item number”) by extracting data such as the item number, item title, issue number, and text, and deleting unnecessary characters from the text data of the item “body”. "Clause data"). Further, the extracted clause data is stored in the contract data table 121 (step S230).

Hereinafter, generation of clause data in the information extraction unit 172 will be described in detail.
For example, the information extraction unit 172 extracts the data of the article number and the article title from the text data with a certain attribute tag “<ZYOU_NUM> Article 6 </ ZYOU_NUM><ZYOU_TITLE> (debt guarantee) </ ZYOU_TITLE>”, When storing in the contract data table 121, the information extraction unit 172 converts the character string “6” obtained by deleting a character string other than numbers from the character string “Article 6” sandwiched between the <ZYOU_NUM> tags. It is stored in the item “Article number” of the table 121. In addition, the character string “collateral liability” obtained by deleting parentheses from the character string “(collateral liability)” sandwiched between <ZYOU_TITLE> tags is stored in the item “article title” of the contract data table 121.

  Through the above processing, from the text data with the attribute tag of the clause of “Article 7 (benefit completed)” as shown in FIG. 11A, the clause data (article number, (Item number, issue number, article). In FIG. 11B, the information extraction unit 172 sets “7” obtained by deleting a character string other than numbers from the character string “Article 7” sandwiched between <ZYOU_NUM> tags from the text data with attribute tag. The item “Article Title” and the character string “2” sandwiched between the <KOU_NUM> tags are added to the item “Article Title” and the character string “2” between the <KOU_NUM> tags. The data is extracted as data of the item “item number” and stored in the contract document data table 121. In FIG. 11B, only the data “2” is extracted as the item “item number”, but the knowledge regarding the clause structure of the above-mentioned contract (the item number in the first item may be omitted) ), The article before the item “Section No.” = “2” is defined as the first section.

In addition, the data of the item “text” shown in FIG. 11B is extracted from the text tag-attached text data from the attribute tag after the attribute tag attached to the item number or item number. The character string up to the attribute tag in front of the attribute tag attached to the title is extracted as data of the item “text”. For example, the text (the following “XXX” part) sandwiched between the attribute tags of the following combinations is extracted as data of the item “article”.
(1): </ ZYOU_NUM> OO <KOU_NUM>
(2): </ ZYOU_NUM> ○○ <TITLE>
(3): </ KOU_NUM> ○○ <TITLE>
In FIG. 11 (b), a character string between the </ ZYOU_NUM> tag and the <KOU_NUM> tag "If the delivery passes the inspection of <REFER> Article 5 </ REFER>, etc ... Is extracted as data of the item “article” of the item “item number” = “1”, and the character string “<REFER> from the </ KOU_NUM> tag to the <TITLE> tag (not shown) Regardless of the </ REFER> rule, “delivery is to be delivered in this contract ...” is extracted as data for the item “article” of the item “item number” = “2”. Then, the data of each extracted text is stored in the contract data table 121. Note that the <REFER> tag in the data of the extracted item “article” is stored in the item “article” of the contract data table 121 without being deleted.

  In addition, the information extraction unit 172 notifies the examination item acquisition unit 180 of information indicating that the clause data is stored in the contract data table 121. The information notified by the information extraction unit 172 to the examination item acquisition unit 180 includes information indicating the type of contract data indicating what contract data the clause data stored in the contract data table 121 is. It is included. For example, information on the item “contract name” included in the contract data table 121 is included.

  When information indicating that the clause data is stored in the contract data table 121 is notified from the information extraction unit 172, an examination item automatic acquisition process (see FIG. 6B) is started.

  When the information indicating that the clause data is stored in the contract data table 121 is input from the information extraction unit 172, the examination item acquisition unit 180 is based on the information indicating the type of contract data included in the notified information. Thus, the examination item data is acquired from the examination item data table 131 in the examination item data storage unit 130 (step S310).

  For example, when the information indicating the type of contract document data notified is “software development contract”, the screening item data to be confirmed in this “software development contract” is acquired from the screening item data table 131. More specifically, the examination item acquisition unit 180 has an item “item No” = “1” in which the item “corresponding contract” in the examination item data table 131 shown in FIG. 12 is “software development contract”. Obtain examination item data.

  The examination item acquisition unit 180 also includes items “check item”, “risk factor”, “answer option 1”, “answer option 1”, “item in the examination item data corresponding to the item“ item No ”output to the examination item corresponding clause search unit 190. Data of “answer option 2” and item “assumed risk” is output to the display screen creation unit 200 (step S320). Hereinafter, the data that the examination item acquisition unit 180 outputs to the display screen creation unit 200 is referred to as risk evaluation data. Thus, risk evaluation data is presented to the user.

Hereinafter, the display of risk evaluation data in the process of the examination item acquisition unit 180 will be described in detail.
For example, when the risk evaluation data is presented to the user, a display as shown in FIG. 13 is displayed on the risk evaluation list 220a in the examination screen 200a shown in FIG. In FIG. 13, the check item list 221a displays data of the item “check item” of the examination item data table 131 shown in FIG. The data of the item “Answer option 1” in the examination item data table 131 shown in FIG. 12 describes the conditions under which the customer can recover the expenses when the contract is canceled in the high risk. No. ”and“ Answer option 2 ”data“ Low risk: The contract (draft) etc. describes the conditions under which the customer can recover the expenses if canceled mid-term ”is displayed and assumed In the risk column 223a, the data of the item “assumed risk” in the examination item data table 131 shown in FIG. Masu. "Is displayed.
Also, the check box 2221a is a check box corresponding to the item “answer option 1” in the examination item data table 131 shown in FIG. 12, and the check box 2222a is the item “in the examination item data table 131 shown in FIG. This is a check box corresponding to “answer option 2”. The input of countermeasures by the user will be described later.

Further, the examination item acquisition unit 180 outputs the information of the item “item No.” in the obtained examination item data to the examination item corresponding clause search unit 190.
When the information of the item “item No.” in the examination item data is input from the examination item acquisition unit 180, the examination item corresponding clause search process (see FIG. 6C) is started.

  When the information on the item “item No.” in the examination item data is input from the examination item acquisition unit 180, the search keyword generation unit 191 receives the item “item No.” from the examination item data table 131 in the examination item data storage unit 130. The data corresponding to the items “check item”, “answer option 1”, “answer option 2” and item “assumed risk” are acquired, and representative keywords related to the examination item are extracted from the text of the acquired data ( Step S410).

Hereinafter, extraction of representative keywords in the search keyword generation unit 191 will be described in detail.
For example, the search keyword generation unit 191 determines that the search keyword generation unit 191 uses the representative keyword “halfway / cancellation / cost / collection / possible” from the text data of the item “check item”. The process in the case of extracting is as follows (see FIG. 14A).
(Process 1): The morphological analysis is performed on the text data of the item “check item”, the text data is divided into word strings, and the part of speech of each word is acquired.
(Process 2): Extract nouns and unknown words having two or more characters from the word string.
In process 2, continuous word strings may be combined and extracted as a compound word, or a verb may be extracted as an action. For example, “halfway cancellation” may be extracted as a compound word of “halfway” and “release”. Further, for example, “collect” may be extracted as the “collection” operation.

  Further, the search keyword generation unit 191 adds (extends) a keyword related to the representative keyword based on the extracted representative keyword (step S420). In this keyword expansion, for example, words having the same meaning may be used in different notations in the contract, so only words extracted from examination item data registered in advance by the system administrator are extracted as keywords. Instead, it is done to extract words that are written in different notations in the contract. Hereinafter, representative keywords and keywords related to the representative keywords are collectively referred to as related keywords.

Hereinafter, extraction of related keywords in the search keyword generation unit 191 will be described in detail.
For example, when the search keyword generation unit 191 expands the extracted representative keyword “halfway / cancellation / cost / collection / possible”, the search keyword generation unit 191 performs the following method.
(Method 1): Using a synonym dictionary or the like, add keywords related to the representative keyword (for example, “middle” that is a synonym for “midway” and “cancel” that is a synonym for “cancel”) (FIG. 14 (b-1)).
(Method 2): The user adds a keyword via the user interface for correction (see FIG. 14B-2).

  In addition, the search keyword generation unit 191 outputs the extracted and added related keywords to the corresponding clause search unit 192.

  When the related keyword is input from the search keyword generation unit 191, the corresponding clause search unit 192 acquires the clause data from the contract document data table 121 in the contract document data storage unit 120. Then, based on the related keyword, the related keyword included in the acquired clause data is searched, and the text data (hereinafter referred to as “related”) of the item “body” in the contract document data table 121 including the information of the searched related keyword. (Referred to as clause) "(step S430).

Hereinafter, a procedure for extracting related clauses in the corresponding clause search unit 192 will be described in detail (see FIG. 15).
(Procedure 1): The corresponding clause search unit 192 calculates a score for the clause data based on the related keyword (see FIG. 15A).
(Procedure 2): The related clauses of the number set in advance in descending order are extracted as the clauses related to the examination items (see FIG. 15B). FIG. 15B shows an example in which three related clauses are extracted.
As the scoring algorithm, for example, a general BM25 known as a scoring technique for full-text search is used.

  Further, with respect to the clause data in which the related keyword is detected, that is, the data of the item “sentence”, a highlighting <KEY> tag may be added to the data indicating the keyword portion. Similarly, it is possible to add a <KEY> tag for highlighting to data indicating a keyword part in the text data of the related clause, that is, the item “body”. For example, if the <KEY> tag for highlighting is added to the keyword “canceled” for the text data of the related clause “partially can be removed,” “partially <key> canceled </ KEY>”. It shall be possible. " Hereinafter, the related clauses to which the <KEY> tag for highlighting is added are referred to as “related clauses with keyword tags”.

  The examination item corresponding clause search unit 190 (the search keyword generation unit 191 and the corresponding clause search unit 192) outputs the correction user interface for adding the keyword and the extracted related clause to the display screen creation unit 200 (step S440). .

Hereinafter, keyword addition and display of related clauses in the processing of the examination item corresponding clause search unit 190 will be described in detail.
In the process (method 2) of the search keyword generation unit 191, when a keyword set by the user is received, for example, a correction user interface for adding a keyword is searched for a check basis / related clause search in the examination screen 200 a shown in FIG. A search keyword field 231a and a search button 232a as shown in FIG. 16 are displayed in the field 230a. The keyword input by the user will be described later.

Further, in the process of the corresponding clause search unit 192, when the related clause with keyword tag is presented to the user, for example, the check basis / related clause search field 230a in the examination screen 200a shown in FIG. The related clause column 233a is displayed. In FIG. 16, the related clause shown in FIG. 15B is displayed in the related clause column 233a, and the character region portion of the detected related keyword is highlighted by the <KEY> tag for highlighting. To do. For example, when the background of a character string sandwiched between <KEY> tags is highlighted by making it “orange”, the <KEY> tag is changed to <span style = “background-color: orange;”> .
In FIG. 16, the related keyword highlighting is shaded. For example, the character size, thickness, character color, character font, shading / filling of the character (character area), underline, etc. The related keyword portion detected by the method may be highlighted.
In the related clause column 233a, the score when the corresponding clause search unit 192 extracts the related clause is displayed.
The input of countermeasures by the user will be described later.

  The display screen generation unit 200 generates display screen data (risk evaluation list 220a shown in FIG. 8) to be output to the application program 30 based on the risk evaluation data input from the examination item acquisition unit 180, and the user interface unit 150. Output to. Further, the display screen generation unit 200 displays the display screen data to be output to the application program 30 based on the related clause with keyword tag input from the corresponding clause search unit 192 (check basis / related clause search field 230a shown in FIG. 8). Is output to the user interface unit 150. Further, the display screen generation unit 200 generates display screen data for displaying the data of the item “risk factor” in the examination item data table 131 in, for example, the check item list 210a (check item column 211a) in FIG. The data is output to the interface unit 150.

  Hereinafter, display screen data generated by the display screen generation unit 200 will be described in detail.
