Contract Document Review Program for Multi-Document Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing legal document review systems, such as those described in Japanese Patent Laid-Open No. 2019-114285, face challenges in accurately evaluating contract documents when content is split across multiple documents, leading to potential misevaluation or omission of important information due to the presence of related but separate legal documents.
Innovation Solution
A contract document review program that reads and compares multiple related contract documents, generates comments on the first document, and modifies these comments based on the content of the second document, ensuring accurate review by including addition, change, or deletion of comments to reflect the complete contractual context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a legal document review system evaluates content of one legal document in isolation, then the evaluation process is simple and fast, but the evaluation accuracy deteriorates when related legal documents exist
Solution Approach 1:
The system segments the evaluation process into two distinct phases: first evaluating each legal document individually to maintain processing efficiency, then performing a second-phase cross-document verification to ensure evaluation accuracy. This segmentation allows the system to benefit from both fast individual evaluation and accurate comprehensive review.
Solution Approach 2:
The system performs preliminary individual document evaluation before conducting the final cross-document verification. This preliminary action establishes baseline evaluations that are then refined and adjusted based on relationships with related documents, ensuring both efficiency and accuracy in the overall evaluation process.
2Measurement precision
If a user manually reviews evaluation results by comparing multiple related legal documents, then evaluation accuracy improves, but the time and effort required increases significantly
Solution Approach 1:
The system introduces an intermediary automated verification process that acts as a mediator between individual document evaluations and final conclusions. This intermediary cross-checks evaluations across related documents, providing accurate comprehensive review without requiring significant user time or effort for manual comparison.
Solution Approach 2:
The system performs self-verification by automatically cross-checking evaluation results across multiple related documents without requiring user intervention. The system independently identifies and resolves potential evaluation conflicts, saving user time while maintaining high evaluation accuracy.
3Productivity
If the system only reviews a single contract document, then the review process is quick and straightforward, but important information from related documents may be omitted
Solution Approach 1:
The system merges the review process to include both the primary contract document and related documents in a unified evaluation framework. By combining information from multiple sources while maintaining efficient processing, the system ensures complete information coverage without sacrificing review speed.
Solution Approach 2:
The system is designed with multi-functionality to handle both single-document and multi-document review scenarios. It can automatically detect and incorporate related documents into the review process, ensuring information completeness while maintaining efficiency through adaptive processing that adjusts to the number of documents involved.

AI summary
The present invention is a contract document review program (10), the contract document review program (10) causing a computer to function as: a contract document reading unit (20) for reading at least document files of a first contract document and a second contract document related to the first contract document, into a computer; a comment generation unit (22) generating comments on articles included in at least the first contract document, based on the document files read by the contract document reading unit; a comment modification unit (24) performing modification including addition, change and/or deletion for the generated comments, based on content of the second contract document; and a comment output unit (32) outputting the comments on the articles of the first contract document generated by the comment generation unit and modified by the comment modification unit.
