<Details of the embodiment>
Hereinafter, regarding the legal text evaluation method, the legal text evaluation program, the legal text evaluation device, and the legal text evaluation system according to the embodiment of the present invention, refer to the drawings by taking the legal text evaluation system (hereinafter referred to as “this system”) as an example. I will explain while doing. In the accompanying drawings, the same or similar elements are designated by the same or similar reference numerals, and duplicate description of the same or similar elements may be omitted in the description of each embodiment. In addition, the features shown in each embodiment can be applied to other embodiments as long as they do not contradict each other.

<Overview>
This system is a system for evaluating document files including legal texts such as contracts, and in particular, sets an evaluation range (hereinafter sometimes referred to as "review point") to be reviewed in advance. By doing so, it relates to a technology that can shorten the time required for confirmation work of contracts and the like. For example, in the evaluation of contracts, etc., each person in charge or an outside expert evaluates based on the company's evaluation policy (the provisions here can be concessed / cannot be concessed, etc.). At this time, the evaluation policy is often different depending on the company. By picking up the evaluation target as in the present embodiment, it is possible to automatically perform an evaluation consistent with the evaluation policy of the legal text of the company. In addition, in the case of contracts containing a large number of clauses, it is possible to improve the efficiency of operations by narrowing down and clarifying the clauses (issues) that must be considered more carefully.

In addition to contracts, terms of use, notifications, etc., the subject of evaluation of the present invention covers all documents including laws and regulations and other legal texts, and also includes notifications and other documents to be submitted to other administrative agencies. .. Furthermore, it can be applied to any document that includes the advantages / disadvantages / superiority / inferiority / rights / obligations of the parties.

Further, in the present embodiment, the direct target of the evaluation is defined as "legal text", but the input to the system can be the entire legal document (document file, etc.) including the legal text. ..

FIG. 1 is an overall schematic diagram of this system. The system 1 includes a server terminal 100 and a user terminal 200. The server terminal 100 is connected to the user terminal 200 via the network 50. For the sake of simplicity, FIG. 1 shows only one user terminal, but the present invention is not limited to this, and two or more user terminals may be used.

In this system, when a document file or the like including legal sentences is transmitted from the user terminal 200 to the server terminal 100, the server terminal 100 performs a legal evaluation and the evaluation result is transmitted to the user terminal 200.

An outline of the hardware configuration of the server terminal 100 and the user terminal 200 will be described with reference to FIGS. 2 and 3. The server terminal 100 shown in FIG. 2 is an information processing device for providing services through an application, and may be a general-purpose computer such as a workstation or a personal computer, or may be logically realized by cloud computing. May be done. The server terminal 100 includes a processor 10, a memory 11, a storage 12, a communication interface (IF) 13, an input / output unit 14, and the like, which are electrically connected to each other through a bus 15.

The processor 10 is an arithmetic unit that controls the operation of the entire server terminal 100, controls the transmission and reception of data between each element, and performs information processing necessary for executing an application. For example, the processor 10 is a CPU (Central Processing Unit), and executes each information processing by executing a program or the like stored in the storage 12 and expanded in the memory 11.

The memory 11 includes a main storage composed of a volatile storage device such as a DRAM (Dynamic Random Access Memory) and an auxiliary storage composed of a non-volatile storage device such as a flash memory or an HDD (Hard Disc Drive). .. The memory 11 is used as a work area or the like of the processor 10, and also stores a BIOS (Basic Input / Output System) executed when the server terminal 100 is started, various setting information, and the like. The storage 12 stores various programs such as an application program and a user authentication program. A database storing data used for each process of the application may be built in the storage 12.

The communication interface 13 connects the server terminal 100 to the network 400 and communicates with the user terminal 200. The input / output unit 14 is an information input device such as a mouse and a keyboard, and an output device such as a display. The bus 15 is commonly connected to each of the above elements and transmits, for example, an address signal, a data signal and various control signals.

The user terminal 200 shown in FIG. 3 also includes a processor 20, a memory 21, a storage 22, a communication interface (IF) 23, an input / output unit 14, and the like, which are electrically connected to each other through a bus 15. .. Since the function of each element can be configured in the same manner as the server terminal 100 described above, detailed description of each element will be omitted.

The functional configuration of the system 1 will be described with reference to FIGS. 4 and 5.

FIG. 4 is an exemplary block diagram focusing on the functions implemented in the server terminals 100, respectively. The server terminal 100 includes a communication unit 110, a determination unit 130, a registration unit 150, an application unit 170, and a storage unit 190, and interacts with each other. The determination unit 130 further includes an input unit 132, a reading unit 134, an evaluation unit 136, and a correction unit 138. The registration unit 150 further includes an evaluation range information registration unit 152 and an advantage information registration 154. The storage unit 190 further includes evaluation range information 192, evaluation rule 194, superiority information 196, and clause sentence example information 196.

The communication unit 110 communicates with the user terminal 200. The determination unit 130 evaluates the legal text. The input unit 132 extracts the legal text to be evaluated from the legal document file. The reading unit reads the evaluation range information regarding the evaluation range of the legal text and the evaluation rule of the legal text. The evaluation unit 136 evaluates at least the range corresponding to the evaluation range information of the legal text based on the evaluation rule. The evaluation rule in the present embodiment includes a rule for determining whether or not the content is advantageous to the user of the legal text by using the score. The amendment unit 138 corrects the score with reference to the clause sentence example information 198 based on the superiority information regarding at least the parties in the legal text. According to such a configuration, it is possible to perform the optimum evaluation for the parties concerned.

Evaluation scope information is, for example, a clause that can be included in legal text. That is, the range of evaluation can be set as the presence or absence of one or more clauses that specify the specified contents or a specific range within the clauses. The evaluation range information can be registered in advance from the user by the evaluation range information registration 152. This allows users to check for omissions in important terms and receive only feedback on specified terms. Similarly, the superiority information can be registered in advance from the user by the superiority information registration unit 154.

The evaluation range that can be set for each clause described above may have a plurality of evaluation elements. That is, when a certain clause (for example, "damages clause") is registered, whether or not the elements constituting the clause (subjective requirement, objective requirement, expense item, etc., but not limited to this) are included. Whether the content is advantageous or disadvantageous is also set as an evaluation target. This makes it possible to evaluate more detailed contents.

In the present embodiment, the evaluation unit can also propose an amendment to the clause by referring to the clause sentence example information 198. The proposed amendment can also propose, for example, multiple patterns according to the stage of superiority of the parties based on the superiority information.

As an example of the above-mentioned evaluation and evaluation rule, for example, the following method can be adopted. Evaluation rules are set according to the legal nature of the relevant legal text. As an example of the contents of the evaluation rule, for example, a table used for scoring used by the evaluation unit may be adopted.

Specifically, the importance of the characters contained in the legal text, the title, the presence or absence of essential words, the strength of the expression, the magnitude of the numerical value, the length of the period, and other factors are used as items for judgment. It is conceivable to use a table that determines and scores based on whether or not the item is satisfied. By adopting this configuration, it becomes possible to evaluate and score character contents created with various expressions from various angles.

FIG. 5 is an exemplary block diagram focusing on the functions implemented in the user terminals 200, respectively. The user terminal 200 includes a communication unit 210, a storage unit 220, an input unit 240, an output unit 250, and an application unit 270, and interacts with each other. The storage unit 220 stores a file of a legal document to be evaluated, and cooperates with the communication unit 110 and the application unit 170 of the server terminal 100 via the communication unit 210.

Each element in each hardware configuration of the server terminal 100 and the user terminal 200 shown in FIGS. 2 and 3, each functional block shown in FIG. 4, and each information shown in FIG. 5 are merely examples. Not limited to these. In particular, each functional block shown in FIG. 4 may be implemented as part of the hardware and / or as part of the software.

Further, at least a part of each functional block of the server terminal 100 shown in FIG. 4 may be configured to be possessed by the user terminal 200. At least a part of each function of the user terminal 200 may be configured to be possessed by the server terminal 100.

That is, the method according to one embodiment can be executed by an information processing device arbitrarily selected from the server terminal 100 and the user terminal 200. In addition, the information held by the storage unit 190 shown in FIG. 4 is not limited to the configuration, data type, and data item shown in the figure.

With reference to FIGS. 6 to 12, the processing between the user terminal 200 and the server terminal 100 will be described with reference to a screen example displayed on the user terminal.

As shown in FIG. 7, the user accesses a screen for setting / registering an evaluation range (review point). As shown in FIG. 8, the user can set a review point for each contract type, for example. The illustrated screen example exemplifies a nondisclosure agreement (NDA), personnel introduction, SaaS terms of use, a dealer / agency / agency, an advertising management consignment / advertising agency, and an investment contract. Is not limited to this. Hereinafter, a nondisclosure agreement (NDA) will be described as an example.

As shown in FIGS. 9 and 10, the review points according to the present embodiment can set the evaluation range on a clause-by-clause basis. In the illustrated screen example, "a clause regarding the definition of confidential information (contents of information)", "a clause regarding the definition of confidential information (method of disclosure)", and "exceptions for prohibition of disclosure to a third party" (exceptions for prohibition of disclosure to a third party). "Disclosure scope", "Obligation (responsibility) when disclosing to a third party", "Audit clause", "Handling of rights related to deliverables" are exemplified. Not limited to this.

As shown in FIG. 10, by displaying the review points in terms of clauses in this way, the user can pick up and evaluate the clauses that are important to the company and the clauses that can be the points of discussion of this contract. Become. The set review points are registered in the evaluation range information 192 of the storage unit 190 by the evaluation range information registration unit 152. By registering the review points once set in this way in the evaluation range information, efficient evaluation output will be possible without the need for special selection from the next time onward, so laws such as contracts with the same type and content It is possible to improve the efficiency of evaluation when you want to check a large number of documents.

Returning to FIG. 6, after setting the review points in advance, the user sends a legal document (SQ101). At this time, superiority information is received from the user. The server terminal 100 reads out the information in the storage unit 190 and the registration unit 150 (SQ102), and evaluates the legal text in the legal document based on the evaluation range information and the evaluation rule (SQ104). At the same time, for clauses with a low evaluation (that is, disadvantageous to oneself), an amendment proposal is generated and output to the user terminal 200 (SQ110).

The results of the evaluation can be displayed as a summary in the format shown in FIG. For example, by displaying "There are 14 improvements in this contract", the total number of cases to be improved / corrected can be grasped. The breakdown of 14 cases is, for example, "There are 10 disadvantageous clauses", "There are 3 slightly disadvantageous clauses", and "One item that is normally included is missing". In addition to the advantages and disadvantages of, the presence or absence of provisions (missing, etc.) can also be evaluated.

As shown in FIG. 12, the evaluation result can be displayed for each "article", "item", "article content", and "risk evaluation" item of the article. As shown in the figure, the evaluation of advantages and disadvantages is displayed in five stages of "disadvantage", "slightly disadvantageous", "appropriate", "slightly advantageous", and "advantageous", and is intuitively easy to understand.

In addition, as the content of the risk assessment, for example, along with the explanation of the clause that "the purpose of disclosure of confidential information is defined and it is meaningful to define the scope of the obligation to prohibit the use for other purposes", "the purpose is limited". It is stipulated, and it can be said that it is a slightly advantageous rule for the disclosing party. "

As a display method (UI) of the evaluation result in the present embodiment, for example, whether or not the evaluation result is advantageous to the user is displayed and output together with the display content using at least one element of color, size, and shape. You may do so. The color may be expressed by using a color system such as RGB or Lab for each evaluation result, and may be expressed as a name representing a specific color such as "red", "blue", and "green". The color information may be composed of only one color, or may be composed of only a plurality of colors. A configuration is also conceivable in which the brightness of the color or the like changes with a gradation as the evaluation changes, and if such a configuration is adopted, it becomes possible to grasp the high and low of the evaluation with even greater visibility.

Regarding the size, it is conceivable to display a predetermined display content according to the high or low evaluation. Specifically, if the evaluation is favorable to oneself, the display may be small, and if the evaluation is unfavorable, the display may be large. By adopting this configuration, it becomes possible for the user to intuitively grasp the advantages and disadvantages of the character content.

Regarding the shape, in addition to the case of a circle, quadrangle, rectangle, sphere or other geometric figure shape, when using a pictogram such as a character, or when using a symbolic shape such as "○", "×", "△", etc. It may be used.

The display content output by the UI output means may be generated by combining the display contents having the configurations described so far. That is, it is possible to generate display contents by combining colors and sizes or by combining colors and shapes according to the evaluation result. By adopting this configuration, it is possible to flexibly output display contents for various evaluation results, so that the visibility of a wide range of evaluation results can be improved.

The embodiments described above are merely examples for facilitating the understanding of the present invention, and are not intended to limit the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof, and the present invention includes its equivalents.
