Embodiments for Carrying Out the Invention

[0011] [Embodiment] (Configuration of Document Processing System) Figure 1 is a schematic diagram showing an example of the 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 to be communicable with each other via a network 4. The terminal 2 is operated by a user who wishes to create a document, check the document content, and / or review the document, for example. The terminal 3 is operated by another user who wishes to create a document, check the document content, and / or review the document, but is not limited thereto. The user of the terminal 2 and the user of the terminal 3 handle, as document information, for example, a contract, and repeat the confirmation, correction, and approval of the content between the users until the content of the contract becomes mutually agreeable. When mainly performing the confirmation work, the document processing system 5 is used for one user to grasp the content of the document information created by the other user. Also, the document processing system 5 may be used for the user who created the document information to confirm 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 terminal 2 and the terminal 3, and includes electronic components such as a CPU (Central Processing Unit), an HDD (Hard Disk Drive), and a flash memory that have functions for processing information within the main body. Note that the document processing server device 1 does not necessarily have to be configured by a single information processing device, and may be configured such that a plurality of information processing devices cooperate to operate, or may be operated by an arbitrary cloud service. Also, the functions of the document processing server device 1 may be realized within the terminal 2 and / or the terminal 3.

[0014] The terminals 2 and 3 are information processing devices such as a PC (Personal Computer) or a tablet terminal, and include electronic components such as a CPU and a flash memory that have functions for processing information within the main body.

[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 are not legal experts but are persons who need to create a contract, or are legal experts such as lawyers who have knowledge of contract creation. Also, for example, one or both of the users are employees of the company's sales department or employees of the company's legal department.

[0017] As a basic operation, after uploading document information from terminal 2 or terminal 3 to the document processing server device 1, a request is made from terminal 2 and terminal 3 for content analysis of the document information on the document processing server device 1, and the analysis result is confirmed on the display units of terminal 2 and terminal 3.

[0018] In this embodiment, mainly, the document processing server device 1 extracts the range of character strings from the document information as element information, associates the element information with each other based on the content of the document information, and presents information regarding the relationship to one or both of the users. Here, the element information includes a subject element that is a character string representing the subject of a sentence, a defining element that is a character string (often a verb phrase or a predicate, but there are exceptions) that defines the action and / or state of the subject, and a limiting element that is a character string that limits the action and / or state of the defining element. When the document information is a contract, for example, the subject element is a party that concludes a contract, etc. (including a third party or an uncertain person), and the defining elements are the rights of the party, the obligations that the party should follow, prohibitions (no rights), exemptions (no obligations), damage compensation included in the obligations, etc. Also, the limiting elements are conditions, exceptions, durations, etc. that limit the content of rights, obligations, etc.

[0019] Note that the parties are proper names that are the subject (it may be an indefinite person without a proper name). An obligation is composed of, for example, one verb phrase at most with endings such as "must", "shall", "do", etc. (when multiple verb phrases are connected by a conjunction, each phrase is split). A right is composed of, for example, one verb phrase at most with endings such as "can do", etc. (when multiple verb phrases are connected by a conjunction, each phrase is split). Note that obligations and rights allow exceptions other than verb phrases as long as they define the actions and / or states of the subject. A condition is, for example, a singular or plural clause with endings such as "when", "in the case of", etc. An exception is, for example, a singular or plural clause with endings such as "this does not apply in the case of", "except for the case of", etc. Embodiments will be described below.

[0020] Also, although the terminal 2 and the terminal 3 are each shown as a single unit, a plurality of units may be connected to the network 4, and similarly, there may be a plurality of users who operate them.

[0021] (Configuration of the document processing server device) FIG. 2 is a block diagram showing a configuration example of the document processing server device 1 according to the embodiment.

[0022] The document processing server device 1 is composed of a CPU etc., and includes a control unit 10 that controls each part and executes various programs, a storage unit 11 that is composed of a storage medium such as a flash memory and stores information, and a communication unit 12 that functions as a communication interface for communicating with the outside via the network 4.

[0023] 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 that functions as a communication interface. By executing a document processing program 110 described later, the control unit 10 functions as a document reception means 100, a range extraction means 101, a specified element association means 102, a limiting element association means 103, a display control means 104, and the like.

[0024] The document reception means 100 receives a contract document from the terminal 2 or the terminal 3 as document information 111 and stores it in the storage unit 11.

[0025] The range extraction means 101 extracts from the character string of the document information 111 a subject element that is the range of the character string representing the subject, a specified element that is the range of the character string defining the operation and / or state of the subject, and a limiting element that is the range of the character string limiting the operation and / or state of the specified element, and stores them in the storage unit 11 as element information 112. Specific examples of the extraction will be described later.

[0026] The specified element association means 102 associates the subject element and the specified element among the element information 112 based on the content of the document information 111 and records it in the association information 113. Specific examples of the association will be described later.

[0027] The limiting element association means 103 associates the specified element and the limiting element among the element information 112 based on the content of the document information 111 and records it in the association information 113. Specific examples of the association will be described later.

[0028] The display control means 104 controls the display on the display units of the terminals 2 and 3 in a predetermined method for the document information 111, the element information 112, and the association information 113 in the storage unit 11 and the output results of the respective means 100-103. Details of the display method will be described later.

[0029] 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 or the like and the communication unit 12 that functions as a communication interface. The storage unit 11 stores a document processing program 110 that operates the control unit 10 as each of the above-described means 100-104, document information 111, element information 112, association information 113, and the like.

[0030] FIG. 3 is a schematic diagram showing a configuration example of the document information 111.

[0031] As an example, the document information 111a is a contract, and has a contract title 111a1, a preamble 111a2, and a plurality of subsequent clauses (clause units) 111a3, 111a4, 111a5, 111a6,.... Further, the clauses (clause units) 111a3, 111a4, 111a5, 111a6,... may include more divided units such as a plurality of items and numbers. Also, depending on the content of the contract, it may be divided over a plurality of units.

[0032] FIG. 4 is a schematic diagram showing a configuration example of the element information 112.

[0033] The element information 112 has an element ID for identifying an element, specific content of the element, a text range indicating the position information of the element in the document information 111, and an element type indicating to which type among parties, obligations, rights, conditions, etc. the element belongs.

[0034] FIG. 5 is a schematic diagram showing a configuration example of the association information 113.

[0035] The association information 113 has a subject element ID that is an element ID of a subject element, a regulation element ID that is an element ID of a regulation element, and a condition element ID that is an element ID of a condition element. Note that each ID may be replaced by / and include items of the element information 112.

[0036] (Operation of the Document Processing System) Next, the operations of the first embodiment will be described by dividing them into (1) basic operations and (2) element association operations. Hereinafter, the operations will be described with the terminal 2 as the operation target, but the description will be omitted if the same operations are performed when the terminal 2 is replaced with the terminal 3.

[0037] (1) Basic operations First, the user operates the terminal 2 to log in to the service provided by the document processing server device 1. When the terminal 2 receives the input of information such as the user ID and password from the user, it transmits an authentication request to the document processing server device 1 together with the information.

[0038] When the document processing server device 1 receives an authentication request together with information such as the user ID and password from the terminal 2, it refers to user information (not shown) including the pre-registered user ID and password, etc., and authenticates the requester as a user.

[0039] (2) Element association operations FIG. 13 is a flowchart showing the element association operation of the document processing server device 1.

[0040] Next, when the user completes logging in to the service, the user operates the terminal 2 to upload the document information of the contract document for which analysis is desired to the document processing server device 1. The terminal 2 uploads the document information to the document processing server device 1.

[0041] The document receiving means 100 of the document processing server device 1 receives the document information 111 from the terminal 2 operated by the requester and stores it in the storage unit 11 (S1).

[0042] Next, the user operates the terminal 2 to select the document information 111 for which analysis is desired from the uploaded document information 111. The terminal 2 transmits an analysis request for the document information 111 to the document processing server device 1.

[0043] When the range extraction means 101 of the document processing server device 1 receives an analysis request for the document information 111, it extracts from the character string of the document information 111 a subject element which is a character string representing a subject, a defining element which is a character string defining the operation and / or state of the subject, and a limiting element which is a character string limiting the operation and / or state of the defining element, and stores them in the storage unit 11 as element information 112 (S2). The extraction is performed, for example, by setting a party as the subject element, rights and obligations as the defining elements, and conditions and exceptions as the limiting elements, and using what has learned BIO (Begin-Inside-Outside) labels by BILSTM-CRF (Bidirectional Long Short Term Memory-Conditional Random Field) for prediction, but the extraction method is not limited to this. For example, a machine learning method such as CRF (Conditional Random Field) or other rule-based methods may be used.

[0044] For example, as shown in FIG. 4, the text range of the document information 111 (a range defined by the number of paragraphs, lines, number of characters, etc.) and the element information 112 in which the types of elements are specified are extracted. For example, the content "Legal Force Co., Ltd." is extracted from the text range from the 3rd character of the 2nd line to the 14th character of the 2nd line of the document information 111 and identified as a party element which is a subject element. Also, the content "In accordance with laws, customs, etc., with good faith..." is extracted from the text range from the 1st character of the 54th line to the 12th character of the 56th line of the document information 111 and identified as an obligation element which is a defining element. Further, the content "When matters not stipulated in this contract occur..." is extracted from the text range from the 1st character of the 53rd line to the 19th character of the 53rd line of the document information 111 and identified as a condition element which is a limiting element.

[0045] Next, the specified element association means 102 of the document processing server device 1 associates the subject element and the specified element among the element information 112 and records them in the association information 113 (S3). Since the subject element and the specified element have a many-to-many relationship (a group of parties and a group of rights and obligations), for example, logistic regression is used to perform binary classification for all combinations to make the association. Note that if a many-to-many association is possible, other association methods such as using a search technique may be used.

[0046] Also, the limiting element association means 103 of the document processing server device 1 associates the specified element and the limiting element among the element information 112 and records them in the association information 113 (S4). Since the specified element and the limiting element have a many-to-many relationship (a group of rights and obligations and a group of conditions and exceptions), for example, logistic regression is used to perform binary classification for all combinations to make the association. Note that if a many-to-many association is possible, other association methods such as using a search technique may be used.

[0047] Note that pruning processing may also be performed when associating the specified element and the limiting element. The pruning processing uses units such as the number of characters, articles, paragraphs, clauses, lines, sentences, etc., and when the distance at the character position between elements based on the unit is farther than a predetermined distance, it is not used as an association target. Further, pruning processing may also be performed when associating the subject element and the specified element. Also, steps S3 and S4 may be processed in any order or simultaneously.

[0048] For example, as shown in FIG. 5, the association information 113 that defines the relevance of each element is recorded. For example, "Legal Force Co., Ltd." with the subject element ID "001" is associated with "Comply with laws, customs, etc. with good faith..." with the specified element ID "002", and "Comply with laws, customs, etc. with good faith..." with the specified element ID "002" is associated with "When matters not specified in this contract occur..." with the limiting element ID "003".

[0049] The associated information 113 may be expressed not only in a table format as shown in FIG. 5 but also, for example, by adding annotations to the document information 111. Note that the following annotations represent that P is Party, R is Right, O is Obligation, C is Condition, and E is Exception.

[0050] FIG. 6 is a schematic diagram showing the configuration of the document information 111 to which annotations are added.

[0051] The " <p1>」and「< / p1> " added to the start and end points of the range 101a1 is an annotation indicating the first subject element. Also, the " <p2>」and「< / p2> " added to the start and end points of the range 101a2 is an annotation indicating the second subject element.

[0052] Also, the "<O1 - P2>" and "< / O1 - P2>" added to the start and end points of the range 101a3 are annotations indicating the defining elements of the first obligation associated with the second subject element. Also, the "<C - O2>" and "< / C - O2>" added to the start and end points of the range 101a4 are annotations indicating the limiting elements associated with the second defining element. Also, the "<O2 - P1>" and "< / O2 - P1>" added to the start and end points of the range 101a5 are annotations indicating the defining elements of the second obligation associated with the first subject element.

[0053] Also, the "<R1 - P1>" and "< / R1 - P1>" added to the start and end points of the range 101a6 are annotations indicating the defining elements of the first right associated with the first subject element. Also, the "<O8 - P2>" and "< / O8 - P2>" added to the start and end points of the range 101a7 are annotations indicating the defining elements of the eighth obligation associated with the second subject element.

[0054] Note that the annotation can be inserted in the same way in contracts other than Japanese. For example, in the case of English, the annotation is added as shown below.

[0055] Figure 7 is a schematic diagram showing the configuration of the document information 111 with the annotation added.

[0056] The " <p1>」and「< / p1> " added at the start and end points of the range 101b1 is an annotation indicating the first subject element. Also, the " <p2>」and「< / p2> " added at the start and end points of the range 101b2 is an annotation indicating the second subject element.

[0057] Also, the "<O1-P1>" and "< / O1-P1>" added at the start and end points of the range 101b3 are annotations indicating the defining elements of the first obligation associated with the first subject element. Also, the "<O2-P2>" and "< / O2-P2>" added at the start and end points of the range 101b4 are annotations indicating the defining elements of the second obligation associated with the second subject element.

[0058] Next, the document processing server device 1 outputs the association information 113 to the display control means 104 (S5). Note that the document processing server device 1 may output the association information 113 externally, and the output association information 113 may be used by an external device.

[0059] Next, as an example, the display control means 104 performs display processing on the association information 113 and displays the following screen on the display unit of the terminal 2 (S6).

[0060] Figure 8 is a schematic diagram showing an example of the display of the display control means 104.

[0061] The screen 104a has buttons 104a1 and 104a2 for switching parties, a display column 104a3 for displaying the content of the document information 111, and a display column 104a4 for displaying the content of the associated information 113 in tabular form. Additionally, an emphasized display as shown in FIGS. 9 to 12 described later may be added to the display column 104a3.

[0062] The display column 104a4 is displayed by subject element (Parties 1 and 2), and the regulatory elements (obligations, rights) associated with each subject element and the limiting elements (conditions) associated with each regulatory element are displayed, presenting the relationships between the elements in a list.

[0063] Also, as another example, the display control means 104 performs a display process on the associated information 113 and displays a screen as shown below on the display unit of the terminal 2.

[0064] FIG. 9 is a schematic diagram showing a display example of the display control means 104.

[0065] The screen 104b has a legend 104b1 shown by color-coding as an example (due to the convenience of patent drawings, the color-coding is represented by differences in hatching), the party 104b2 who is the principal, the party 104b3 who is the agent, the condition 104b4 which is the condition, the regulatory element 104b5 of the agent, the regulatory element 104b6 of the agent, the regulatory element 104b7 of the principal, and the regulatory element 104b8 of the principal, which are color-coded and highlighted for the content of the document information 111 displayed in text form. In addition to color-coding, the display may be differentiated by font, size, hatching, italic, underline, ruby, etc.

[0066] FIG. 10 is a schematic diagram showing a display example of the display control means 104.

[0067] The screen 104c has a legend 104c1 that shows color-coded examples, a condition 104c2 that is a condition for highlighting the content of the document information 111 displayed in text format, an obligation 104c3 of the consignor, an obligation 104c4 of the consignee, obligations 104c5 and 104c6 of the consignor, conditions 104c7 and 104c8 that are conditions, an obligation 104c9 of the consignor, an obligation 104c10 of the consignee, an obligation 104c11 of the consignor, conditions 104c12 and 104c13 that are conditions, an obligation 104c14 of the consignor, an obligation 104c15 of the consignee, and an obligation 104c16 of the consignor.

[0068] In screens 104b and 104c, each element is color-coded and displayed for the document information 111, and the relationships between the elements are displayed within the document information 111.

[0069] Also, as another example, the display control means 104 performs display processing on the associated information 113 and displays the following screens on the display unit of the terminal 2. This is different from FIGS. 9 and 10 described above in that the legend is divided in more detail.

[0070] FIG. 11 is a schematic diagram showing a display example of the display control means 104.

[0071] The screen 104d has a legend 104d1 that shows color-coded examples, a party 104d2 as the seller who is highlighted for the content of the document information 111 displayed in text format, a party 104d3 as the buyer, mutual obligations 104d4, buyer obligations 104d5, 104d6, 104d7, and 104d8, a seller obligation 104d9, buyer obligations 104d10 and 104d11, buyer obligations 104d12 and 104d13, and mutual obligations 104d14. Note that the conditions and exception conditions in the rights and obligations are underlined.

[0072] Compared with screens 104b and 104c, the screen 104d has each element divided in more detail, each element is color-coded and displayed for the document information 111, and the relationships between the elements are displayed within the document information 111.

[0073] Further, as another example, the display control means 104 performs display processing on the association information 113 and displays a screen as shown below on the display unit of the terminal 2.

[0074] FIG. 12 is a schematic diagram showing a display example of the display control means 104.

[0075] The screen 104e has a pull-down menu 104e1 for selecting an item to be highlighted, a party 104e2 as a seller, a party 104e3 as a buyer, and buyer obligations 104e4, 104e5, and 104e6 that are highlighted with respect to the content of the document information 111 displayed in text form when a buyer obligation is selected.

[0076] On the screen 104e, the selected element "buyer obligation" in the document information 111 is highlighted and emphasized, and the relationship between the elements is displayed in the document information 111. In addition, conditions are displayed using underlines in the highlighted display. Also, conditions and exception conditions in rights and obligations are underlined.

[0077] (Effect of the Embodiment) According to the above-described embodiment, the subject element, the defining element, and the limiting element are extracted from the document information 111, and the extracted subject element, defining element, and limiting element are associated based on the content of the document information 111 to obtain the association information 113. Since the association information 113 is display-controlled by a table format, marking, etc., information for grasping the content of the contract can be presented even when terms that do not correspond to pre-registered information are used. Since the contract is described in a text format, knowledge and skill were required to grasp what rights and obligations are imposed on which parties and what conditions are defined for the rights and obligations. However, by displaying in a table format, marking, etc., an increase in the processes and time required for grasping can be suppressed. Further, by switching the marking items, only the selected item is displayed, so it is easier to grasp the content of the selected item compared to the case where no switching method is used.

[0078] [Other Embodiments] Note that the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the spirit of the present invention.

[0079] For example, the document information 111 is not limited to a contract, and may be a document in other fields such as a law document or an instruction manual as long as it can extract a string range as each element, and the present invention can be similarly applied. Also, the language of the document information 111 is not limited to Japanese or English, and can be applied to other languages as long as it can form a sentence from which each element can be extracted.
