[0011] [Embodiment Mode] (Document Processing System Configuration) FIG. 1 is a schematic diagram showing an example of a configuration of a document processing system according to an embodiment.

[0012] This document processing system 5 is configured by connecting a document processing server device 1, a terminal 2, and a terminal 3 via a network 4 so that they can communicate with each other. Terminal 2 is operated by a user who wishes to manage documents, create documents, check document contents, and / or review documents, and terminal 3 is operated by another user, but is not limited to this. The user of terminal 2 and the user of terminal 3 handle document information, such as contracts, and use the document processing system 5 mainly to manage document information created by one or both users, as well as to manage document information after the contract is concluded, and to check and understand the content of the document information.

[0013] The document processing server device 1 is a server-type information processing device that operates in response to requests from the terminals 2 and 3, and includes electronic components such as a CPU (Central Processing Unit) having functions for processing information within the device itself, an HDD (Hard Disk Drive), and a flash memory. Note that the document processing server device 1 does not necessarily need to be configured as a single information processing device, and may be a device in which multiple information processing devices operate in cooperation with each other, or may be a device that operates using any cloud service. Furthermore, the functions of the document processing server device 1 may be realized within the terminals 2 and / or 3.

[0014] The terminal 2 and the terminal 3 are information processing devices such as PCs (Personal Computers) and tablet terminals, and include electronic components such as a CPU having a function for processing information within the main body, a flash memory, and the like.

[0015] The network 4 is a communication network capable of high-speed communication, and is, for example, a wired or wireless communication network such as the Internet, an intranet, or a LAN (Local Area Network).

[0016] In the above configuration, as an example, the document processed by the document processing server device 1 is a document in the legal field such as a contract, and one or both of the users is a person who is not a legal expert but needs to create a contract, or a legal expert such as a lawyer who has knowledge of creating contracts. Also, for example, one or both of the users is an employee of the company's sales department or an employee of the company's legal department.

[0017] As a basic operation, after document information is uploaded from terminal 2 or terminal 3 to document processing server device 1, the document information is managed in document processing server device 1, and the contents of the document information are confirmed by accessing document processing server device 1 from terminal 2 or terminal 3, but at this time, in order to reduce the burden of confirmation work on the user or to assist the user in creating a contract, the document processing server device 1 extracts information from the document information and displays the extracted information in a format that helps the user understand the contents. Specific examples of display methods will be described later.

[0018] In this embodiment, the document processing server device 1 mainly extracts information indicating the contract status from the document information, and presents the extracted information to one or both users. In the following, a clause may be referred to as a "provision." The embodiment will be described below.

[0019] Although the terminal 2 and the terminal 3 are illustrated as being singular, a plurality of terminals may be connected to the network 4, and similarly, these may be operated by a plurality of users.

[0020] (Configuration of document processing server device) FIG. 2 is a block diagram showing an example of the configuration of the document processing server device 1 according to the embodiment.

[0021] The document processing server device 1 is equipped with a control unit 10 which is composed of a CPU and the like and controls each part and executes various programs, a memory unit 11 which is composed of a storage medium such as a flash memory and stores information, and a communication unit 12 which functions as a communication interface for communicating with the outside via a network 4.

[0022] The control unit 10 is composed of a processor such as a CPU, and is electrically connected to a storage unit 11 composed of a memory, and a communication unit 12 functioning as a communication interface. The control unit 10 executes a document processing program 110 described later, thereby functioning as a contract reception means 100, a contract division means 101, an information extraction means 102, a normalization means 103, a display control means 104, and the like.

[0023] The contract receiving means 100 receives a contract from the terminal 2 or the terminal 3 as document information 111 and stores it in the storage unit 11. The document information 111 may be image information such as a PDF in which text is laid out, or may be information such as a text file or Word file that includes text data.

[0024] If the document information 111 is information other than text, the contract division means 101 converts it into text using OCR (Optical Character Recognition) or the like, then divides the document information 111 into contract components such as title, preface, and article units, and stores them as unit information 112 in the storage unit 11. Note that the unit of division for article units is not limited to articles, and may be clauses and items, or a set of multiple articles, clauses, and items that have a unity of meaning. Also, clauses and items that have a unity of meaning across different articles and clauses may be used.

[0025] The information extraction means 102 extracts information representing the contract contents from the unit information 112 and stores it in the storage unit 11 as extracted information 113 .

[0026] The normalization means 103 normalizes the contents of the extracted information 113 extracted by the information extraction means 102 by standardizing keywords, standardizing the description format, supplementing with reference to other information, inference based on other information, name matching, etc., and stores the normalized extracted information 114 in the storage unit 11. For supplementing with reference to other information, the contract end date is calculated from the contract start date and expiration date. For inference based on other information, for example, a corporate number is estimated based on the company name, date, address, etc. The name matching process is performed by comparing keywords in a dictionary (keyword list) using Levenshtein distance and keyword similarity, and setting the closest ones as normalized strings.

[0027] The display control means 104 controls the display of the document information 111, the unit information 112, the extraction information 113 and the normalized extraction information 114 in the storage unit 11, and the output results of the means 100-103 on the display units of the terminals 2 and 3 in a predetermined manner. The display method will be described in detail later.

[0028] The storage unit 11 is composed of a memory such as a flash memory, and is electrically connected to the control unit 10 composed of a processor, etc., and the communication unit 12 functioning as a communication interface. The storage unit 11 stores a document processing program 110 that causes the control unit 10 to operate as each of the above-mentioned means 100-104, document information 111, unit information 112, extraction information 113, normalized extraction information 114, etc.

[0029] FIG. 3 is a schematic diagram showing an example of the configuration of the document information 111. As shown in FIG.

[0030] The document information 111a is, for example, a contract, and the unit information 112 divided by the contract division means 101 includes the title 112a of the contract. 1 and Preface 112a 2 and the following clauses (clause units) 112a 3 , 112a 4 , 112a 5 .... Also, Article 112a 4 112a 41 , 112a 42 This includes:

[0031] FIG. 4 is a schematic diagram showing an example of the configuration of the extraction information 113. As shown in FIG.

[0032] The extracted information 113 is information extracted by the information extraction means 102, and has an extraction ID for identifying the extracted information, the extracted information extracted from the unit information 112, an extraction item which is the item to which the extracted information belongs, and a reference location which is location information within the unit information 112.

[0033] FIG. 5 is a schematic diagram showing an example of the configuration of the normalized extraction information 114. As shown in FIG.

[0034] The normalized extraction information 114 is information obtained by normalizing the extraction information 113 using the normalization means 103, and includes an extraction ID, extraction information, and normalized extraction information obtained by normalizing the extraction information.

[0035] (Operation of document processing system) Next, the operation of the first embodiment will be explained by dividing it into (1) basic operation, (2) information extraction operation, and (3) extracted information display operation. In the following, the operation will be explained with terminal 2 as the operation target, but if the operation is similar even when terminal 3 is used instead, the explanation will be omitted.

[0036] (1) Basic operation First, a user operates the terminal 2 to log in to a service provided by the document processing server device 1. Upon receiving input of information such as a user ID and password from the user, the terminal 2 transmits an authentication request together with the information to the document processing server device 1.

[0037] When the document processing server device 1 receives an authentication request from the terminal 2 together with information such as a user ID and password, it refers to user information (not shown) including a pre-registered user ID and password, and authenticates the requester as a user.

[0038] Next, when the user has completed logging in to the service, the user operates the terminal 2 to upload the document information of the contract to the document processing server device 1. The terminal 2 uploads the document information to the document processing server device 1.

[0039] (2) Information extraction operation Fig. 10 is a flowchart showing the information extraction operation of the document processing server device 1. Fig. 6 is a schematic diagram for explaining an example of the information extraction operation process.

[0040] The contract receiving means 100 of the document processing server device 1 receives document information 111 from the terminal 2 operated by the client, and stores it in the storage unit 11 (S1).

[0041] Next, the contract division means 101 of the document processing server device 1 divides the document information 111a into each component of the contract, as shown in Fig. 3, to generate unit information 112a and structure it (S2). As an example, the document information 111a is image information such as a PDF (Portable Document Format) file obtained by scanning the original contract, and the contract division means 101 first converts the document information 111a into text using a method such as OCR (Optical Character Reader). The contract division means 101 converts the text information into titles 112a, 1 , Preface 112a 2 , Article 112a 3 ~112a 7 …, term unit 112a 41 , 112a 42 .... The contract division means 101 may further divide the target document information 111a into units of issues, and use units suitable for the structure of the document information 111a to generate unit information 112a. The above division is performed using techniques such as machine learning and regular expressions. Furthermore, division is not a required operation item, and subsequent operations may be performed without division.

[0042] Next, the information extraction means 102 extracts information representing the contract contents from the unit information 112a, which is a structured document, together with the location information of the reference destination of the unit information 112a, into extracted information 113a. 1 ~113a 5 ...(extracted information 113a) and stored in the storage unit 11 (S3). Note that the extraction of the above information is performed using a technique such as named entity recognition using a conditional random field.

[0043] Next, the normalization means 103 normalizes the contents of the extracted information 113a extracted by the information extraction means 102 by standardizing keywords, supplementing with reference to other information, and performing the process shown in FIG. 7 below to generate normalized extracted information 114a. 1 ~114a 5...(normalized extracted information 114a) is stored in the storage unit 11 (S4). The normalized extracted information 114a is managed by items such as title, party 1, party 2, date of conclusion, start date, end date, full text, etc. The normalization of the above information is performed by comparing keywords in a dictionary (keyword list) using techniques such as Levenshtein distance and keyword similarity.

[0044] FIG. 7 is a schematic diagram for explaining an example of the operation of the normalization means 103. As shown in FIG.

[0045] When the normalization means 103 receives a date written in the Japanese calendar, such as "July 1, 2017," in an extraction item related to a date as the extracted information 113, it normalizes the date to a date written in the Gregorian calendar, such as "July 1, 2017," as the normalized extracted information 114. Note that even if the extracted information 113 is written in the Gregorian calendar, normalization is performed in the same way when the order of writing is different, such as "2017 / 7 / 1," "7 / 1 / 2017," or "July 1, 2017."

[0046] In addition, when the normalization means 103 receives an entry including a period such as "one year from July 1, 2017" in an extraction item related to a date as the extracted information 113, it normalizes it to a date corresponding to the end date such as "June 30, 2018" as the normalized extracted information 114.

[0047] In addition, when the normalization means 103 receives a specific description such as "...This contract shall be renewed under the same conditions, and the same shall apply thereafter," in an extracted item regarding renewal as the extracted information 113, it normalizes it to a concise description such as "Automatic renewal available" as the normalized extracted information 114.

[0048] In addition, when the normalization means 103 receives the party status and party name such as "LegalForce Co., Ltd." in the extraction item related to the parties as the extracted information 113, it normalizes it to the parties as "LegalForce Co., Ltd." as the normalized extracted information 114.

[0049] In addition, when the normalization means 103 receives as extraction information 113 the position of the party in an extraction item related to the parties, such as "The person listed at the end of this contract (omitted) LegalForce Co., Ltd." and the name of the party listed in that position, it normalizes the name of the party to "LegalForce Co., Ltd." as normalized extraction information 114.

[0050] In addition, when the normalization means 103 receives a pair of parties such as "LegalForce Co., Ltd. (hereinafter referred to as "Party A") and Attorney Nozomi Tsunoda (hereinafter referred to as "Party B") enter into a consulting agreement (hereinafter referred to as "this agreement") as follows" in an extracted item related to the parties as extracted information 113, it normalizes the pair of parties to "LegalForce Co., Ltd. / Nozomi Tsunoda" as normalized extracted information 114.

[0051] In addition, when the normalization means 103 receives, as the extracted information 113, an extraction item related to a period, an expiration date and period such as "The expiration date of this agreement shall be one year from the date of conclusion of this agreement....Date of conclusion: January 1, 2020", it normalizes it to the start date of conclusion, such as "January 1, 2020", as normalized extracted information 114.

[0052] In addition, the information extraction means 102 and the normalization means 103 perform extraction and normalization automatically as described above, but as shown in Figure 9 below, extraction and normalization of proper nouns, dates, periods, etc. may also be performed in response to user operations.

[0053] FIG. 9 is a schematic diagram showing an example of a screen displayed when extraction information is registered in response to an operation.

[0054] The screen 103b includes an input field 103b for inputting a character string that the user wishes to search for. 1 And a check box 103b to register all search results 2 and a check box 103b for selecting each search result as a registration target. 24 , 103b 25 , 103b 26...and a registration button 103b for registering the search results that you checked in the check box 3 And search result 103b 4 , 103b 5 , 103b 6 Each search result 103b 4 , 103b 5 , 103b 6 …has a similar structure, so search result 103b 4 The structure of the search result 103b is explained below. 4 button 103b for registering the search result as the title of the contract 41 and a button 103b for registering the search results as the names of the parties. 42 and a button 103b for registering the search results as the start date. 43 and a button 103b for registering the search results as the end date. 44 and a display field 103b that displays the search result string. 45 and

[0055] The user inputs the character string he or she wishes to search for in the input field 103b on the screen 103b. 1 Search results for 103b 4 , 103b 5 , 103b 6 Check the details of the test results you wish to register and check box 103b 2 , 103b 24 , 103b 25 , 103b 26 Check ... and press button 103b 41 ~103b 44 is appropriately selected, and the registration button 103b 3 The registration operation is performed by pressing the button.

[0056] The information extraction means 102 and the normalization means 103 register the checked character string in the extraction information 113 and the normalized extraction information 114 .

[0057] (3) Extracted information display operation Next, the user operates the terminal 2 to select a contract in order to request a reference to the contents of a desired contract from the document processing server device 1. The terminal 2 requests the document processing server device 1 to select a contract and to refer to the contents of the selected contract.

[0058] When the display control means 104 of the document processing server device 1 receives a request to select a contract and to refer to the contents of the contract, it processes and displays the normalized extraction information 114a together with the document information 111a and the unit information 112a.

[0059] FIG. 8 is a schematic diagram showing a display example of the display control means 104. As shown in FIG.

[0060] The screen 104a is a screen displayed by the display control means 104, and includes a document information display field 104a for displaying document information 111a, which is the original contract. 1 and a structured document display field 104a that displays unit information 112a, which is a structured document. 2 and a normalized extracted information display section 104a for displaying normalized extracted information 114a for each item. 3 and
