[0012] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are designated by the same reference numerals, and for clarity of explanation, duplicate explanations will be omitted as necessary.

[0013] (First embodiment) First, the configuration of a contract check device 10 according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of a contract check device 10 according to the present disclosure.

[0014] As shown in FIG. 1, the contract checking device 10 includes a contract input unit 11, a summarization unit 12, a questioning unit 13, a summary modification unit 14, a contract modification unit 15, and a contract output unit 16. The contract input unit 11 accepts input of a contract from a user. The summarization unit 12 generates a summary corresponding to at least one key item in the contract and outputs the summary to the user. The questioning unit 13 accepts input of selected items in the summary selected by the user, generates questions related to the selected items in the summary, and outputs the questions to the user. The summary modification unit 14 accepts input of answers to the questions by the user and modifies the content of the selected items in the summary based on the answers. The contract modification unit 15 modifies the content of the contract based on the modified summary. The contract output unit 16 outputs the modified contract to the user.

[0015] The contract checking device 10 according to the first embodiment allows the user to efficiently grasp the key points of a contract from the contract summary. Furthermore, the contract checking device 10 allows the user to change the content of a contract simply by receiving questions from the device regarding selected items in the contract summary and providing their own answers to the questions. Furthermore, the contract checking device 10 allows the user to change the content of a contract while viewing the contract summary, so the user can change the content of the contract without having to go back to the contract and check a huge amount of content. Therefore, the contract checking device 10 allows the user to efficiently change the content of a contract.

[0016] (Second embodiment) Next, the configuration of a contract check device 20 according to the second embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the configuration of a contract check device 20 according to the present disclosure.

[0017] 2, the contract check device 20 is, for example, a server. The contract check device 20 communicates with the user terminal 100 via a network. The communication may be wireless or wired. The network may be, for example, a LAN (Local Area Network), a WAN (Wide Area Network), or the Internet.

[0018] The user terminal 100 is a terminal used by a user, such as a smartphone, tablet, or PC (Personal Computer). The user terminal 100 includes an input unit 101 and an output unit 102. The input unit 101 is, for example, a touch panel, and accepts information input from a user. The output unit 102 is, for example, a display, and displays information to the user.

[0019] The contract check device 20 may be realized as a system including a plurality of devices that communicate with each other. Alternatively, the contract check device 20 may be realized as a single device including the input unit 101 and the output unit 102.

[0020] Specifically, the contract check device 20 includes a contract input unit 21, a summary unit 22, a question unit 23, a summary modification unit 24, a contract modification unit 25, and a contract output unit 26.

[0021] The contract input unit 21 accepts input of a contract from the input unit 101. The types of contract include, for example, a basic contract, an SI (System Integration) contract, and a service contract. The contract whose input is accepted may be a combination of multiple types of contracts.

[0022] The summarization unit 12 generates a summary corresponding to at least one key item in the contract and outputs the summary to the output unit 102. Key items in the contract include, for example, items that are considered to be risky or items that are often overlooked in checks. The at least one key item includes, for example, at least one of the contract period, cancellation conditions, intellectual property, and compensation for damages. The summarization unit 12 generates the summary using, for example, natural language processing (NLP) using artificial intelligence (AI). By outputting the summary to the output unit 102, the user can select an item to be modified in the summary output to the output unit 102 and input the selected item in the summary (hereinafter, the selected item) to the input unit 101.

[0023] The questioning unit 13 receives input of selected items in the summary by the user from the input unit 101, generates a question regarding the selected items in the summary, and outputs the question to the output unit 102. The question is preferably one that allows the user to easily understand and judge the key points of the contract. By outputting the question, the user can input an answer to the question into the input unit 101.

[0024] Specifically, the questioning unit 13 generates a question related to the selection items in the summary, along with multiple options serving as answers to the question. For example, the questioning unit 13 generates a question related to the selection items in the summary, along with multiple options serving as answers to the question, based on a pre-stored trained machine learning model. Here, the trained machine learning model is generated by pattern learning based on training data in which questions related to the selection items in the summary are linked to options serving as answers to the questions. The generated multiple options may include an option indicating the current terms of the contract the user has with the contractor and at least one option different from the options indicating the current terms of the contract. Then, the questioning unit 13 outputs the question and the multiple options to the user. By outputting the question and the multiple options, the user can select a predetermined option from the output multiple options as an answer to the question and input the selected option into the input unit 101.

[0025] The summary modification unit 14 accepts input of an answer to a question from the user. Specifically, the summary modification unit 14 accepts input of an option selected by the user from the multiple output options as input of an answer to the user's question. The summary modification unit 14 changes the content of the selected item in the summary based on the answer, and outputs the modified summary to the output unit 102. The output of the modified summary allows the user to confirm the modified summary.

[0026] The contract modification unit 15 modifies the content of the contract based on the modified summary. Specifically, the summarization unit 12 generates the contract based on the modified summary using natural language processing by AI.

[0027] The contract output unit 16 outputs the changed contract to the output unit 102. In this way, the user can confirm the changed contract.

[0028] Next, the operation of the contract check device 20 according to the second embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the operation of the contract check device 20 of the present disclosure.

[0029] As shown in FIG. 3, first, in step S101, the contract input unit 21 of the contract check device 20 accepts input of the contract from the input unit 101.

[0030] Next, in step S102, the summarization unit 12 generates a summary corresponding to at least one key item in the contract and outputs the summary to the output unit 102. For example, the summarization unit 12 generates the summary using natural language processing by AI. By doing so, the user can select an item to be modified in the summary output to the output unit 102 and input the selected item in the summary to the input unit 101.

[0031] FIG. 4 is a diagram showing an example of a screen including a contract summary output to the output unit 102 by the summarizing unit 12 of the contract check device 20 of the present disclosure.

[0032] In FIG. 4, the key points in the contract are "Article 1: Scope of the Contract" to "Article 12: Negotiations." The summarization unit 12 of the contract check device 20 outputs summaries corresponding to each of "Article 1: Scope of the Contract" to "Article 12: Negotiations" on the screen. The user can select any of the summaries from "Article 1: Scope of the Contract" to "Article 12: Negotiations."

[0033] In the following, a case where the user selects the item "Article 8 Compensation for Damages" (shown as A1 in FIG. 4) will be explained. In this case, the summary of "Article 8 Compensation for Damages" is output on the screen by the summarizing unit 12. The summary of "Article 8 Compensation for Damages" is as follows: <1> , <2> and <3> This includes the following matters. <1> The item in question is, "If Company A pays damages to Company B, or Company B pays damages to Company A, the total amount of such damages shall be limited to the contract amount, regardless of whether the breach of contractual obligations was due to illegal acts, etc." <2> The point is that "there is no obligation to compensate for damages that are not the fault of the parties, damages that the parties could not foresee, or lost profits such as lost opportunities." <3> The clause states, "Claims for damages must be made within one year from the date of completion of the contract."

[0034] The user: <1> ~ <3> You can select one of the following items. <1> ~ <3> By placing the mouse on the display area and clicking, or via the touch panel <1> ~ <3> In the following, the user touches the display area of ​​the summary. <1> A case where the item (shown as A2 in FIG. 4) is selected as a selection item will be described.

[0035] Returning to the explanation of Fig. 3, next, in step S103, the questioning unit 13 accepts an input of a selection item in the summary by the user from the input unit 101, generates a question regarding the selection item in the summary, and outputs the question to the output unit 102. In this way, the user can input an answer to the question into the input unit 101.

[0036] Specifically, the questioning unit 13 generates a question related to the selection in the summary, along with multiple options serving as answers to the question. For example, the questioning unit 13 generates a question related to the selection in the summary, along with multiple options serving as answers to the question, based on a pre-stored trained machine learning model. Here, the trained machine learning model is generated by pattern learning based on training data in which questions related to the selection in the summary are linked to options serving as answers to the questions. The questioning unit 13 then outputs the question related to the selection in the summary and the multiple options to the output unit 102. This allows the user to select a predetermined option from the output multiple options as an answer to the question and input the selected option to the input unit 101.

[0037] 5 is a diagram showing an example of a screen including a question and a plurality of options regarding a selection item in the summary, which is output to the output unit 102 by the question unit 13 of the contract check device 20 of the present disclosure. Here, the example of FIG. 5 shows the screen in which, as described above, the user selects a selection item in the summary. <1> This is the case when the item (shown as A2 in FIG. 4) is selected as the option.

[0038] As shown in FIG. 5, the question output to the output unit 102 by the questioning unit 13 of the contract document checking device 20 is, "What is the upper limit for the amount of damages that Company A will pay to Company B, or Company B will pay to Company A?" The options output together with the question include (1) to (4). (1) is "The contract amount will be the upper limit." (2) is "No upper limit will be set." (3) is "The upper limit will be xx yen." (4) is "Other." The following describes the case where the user selects option (2) (shown as A3 in FIG. 5).

[0039] The generated options may include an option indicating the current contract terms the user has with the contracting party and at least one option that is different from the option indicating the current contract terms. In this case, the option indicating the current contract terms is clearly displayed on the screen. For example, in FIG. 5, option (1) corresponds to the current contract terms and is clearly displayed. Options (2) to (4) correspond to options that are different from the option indicating the current contract terms.

[0040] The output options may include an item in which the user can freely input a value such as a numerical value or a character. For example, the "XX" in (3) "Maximum XX yen" is an item in which the user can freely input a numerical value. When the user selects (3) "Maximum XX yen," the user inputs an appropriate numerical value as "XX" into the input unit 101.

[0041] Returning to the description of Fig. 3, next, in step S104, the summary modification unit 14 accepts input of an answer to the question by the user, modifies the content of the selection items in the summary based on the answer, and outputs the modified summary to the output unit 102. Specifically, the summary modification unit 14 accepts input of an option selected by the user from the multiple output options as input of an answer to the user's question, modifies the content of the selection items in the summary based on the answer, and outputs the modified summary to the output unit 102.

[0042] 6 is a diagram showing an example of a screen including a modified summary output to the output unit 102 by the summary modification unit 14 of the contract check device 20 of the present disclosure. The example in FIG. 6 explains the case where the user selects option (2) (shown as A3 in FIG. 5) as described above.

[0043] As shown in FIG. 6, the items in the summary after the change output by the summary change unit 14 of the contract check device 20 are <1> (shown as A4 in Figure 6) is "There is no upper limit on the amount of damages that Company A will pay to Company B, or Company B will pay to Company A." By doing so, the user can see that the item in the revised summary is <1> When all changes to the summary in the contract have been completed, the user can input an instruction to complete the contract changes into the input unit 101 by clicking "Complete contract changes" (shown as A5 in FIG. 6). On the other hand, when all changes to the summary in the contract have not been completed, the user can select another item from "Article 1 Scope of contract" to "Article 12 (Negotiations)" and change that item as described above.

[0044] Returning to the explanation of Fig. 3, next, in step S105, the contract modification unit 15 determines whether or not it has received, from the input unit 101, an instruction to complete the contract modification from the user. If it is determined that it has received, from the input unit 101, an instruction to complete the contract modification from the user (YES in step S105), the process proceeds to step S106. On the other hand, if it is determined that it has received, from the input unit 101, an instruction to complete the contract modification from the user (YES in step S105), the process returns to step S103. In this case, the user can select and modify another item in the summary.

[0045] In step S106, the contract modification unit 15 modifies the content of the contract based on the modified summary. Specifically, the summarization unit 12 uses natural language processing by AI to generate the modified content of the contract based on the modified summary. Note that the contract modification unit 15 may generate the modified content of the contract only with respect to the changed items in the summary.

[0046] Next, in step S107, the contract output unit 16 outputs the changed contract to the output unit 102.

[0047] As described above, the contract checking device 20 according to the second embodiment allows the user to efficiently grasp the key points of a contract from the contract summary. Furthermore, the contract checking device 20 allows the user to change the content of a contract simply by receiving questions from the device regarding selected items in the contract summary and providing their own answers to the questions. Furthermore, the contract checking device 20 allows the user to change the content of a contract while viewing the contract summary, allowing the user to change the content of the contract without having to go back to the contract and check a huge amount of content. Therefore, the contract checking device 20 allows the user to efficiently change the content of a contract.

[0048] Furthermore, the contract check device 20 outputs a plurality of options that serve as answers to questions to the user, allowing the user to change the content of the contract simply by selecting an option (and entering a simple value). Therefore, the contract check device 20 allows the user to change the content of the contract more efficiently.

[0049] Furthermore, in the contract document checking device 20, the multiple options that serve as answers to the questions include an option that indicates the current contract terms that the user will enter into with the contracting party and at least one option that is different from the options that indicate the current contract terms. Therefore, in the contract document checking device 20, the user can compare the option that the user is considering changing with the current contract terms. Therefore, in the contract document checking device 20, the user does not need to perform the task of checking the current contract terms, and can more efficiently change the contents of the contract.

[0050] Furthermore, the contract check device 20 simultaneously accepts input of a combination of multiple types of contracts, allowing the user to change the contents of a large number of contracts at once.

[0051] (Variation) In addition, the above-mentioned contract checking device 20 is not limited to the above-mentioned configuration, and may also have a function that allows the user to consult with a lawyer online if changes to the content of the contract cannot be handled by AI.
