Document Unit Matching for Clear Contract Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices struggle to efficiently compare and display the relationships between different document units, such as articles or clauses, in a user-friendly manner, particularly in legal documents like contracts, which are often drafted by non-experts in varying styles and formats.
Innovation Solution
A document processing system that divides document information into predefined units, calculates relevance between these units, links them one-to-one based on relevance, and displays the linked units together, allowing users to easily view relationships and differences between documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If document information is divided into predefined units for comparison, then the precision of relationship detection is improved, but the device complexity increases
Solution Approach 1:
The patent segments document information into predefined units (articles, clauses, or paragraphs) before comparison. This segmentation enables precise matching between corresponding units in different documents while simplifying the overall comparison process by breaking down complex documents into manageable, comparable components.
2Loss of information
If one-to-one linking is performed between document units based on relevance, then the clarity of relationship display is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary division of documents into predefined units before the comparison process. This preliminary action organizes the document structure in advance, enabling faster relevance calculation and one-to-one linking during the actual comparison, thereby reducing overall processing time while maintaining clear relationship display.
3Adaptability or versatility
If documents in different styles and formats are compared, then the adaptability of the system is improved, but the difficulty of detecting relationships increases
Solution Approach 1:
The patent employs a universal comparison framework that works across different document styles and formats. By using standardized predefined units and relevance calculation methods that are format-agnostic, the system achieves multi-functionality in handling various document types while maintaining consistent relationship detection capabilities.

AI summary
An information processing device includes one or more hardware processors configured to divide first document information and second document information in a predefined unit; calculate a degree of relevance between units included in the first document information and units included in the second document information; link the units included in the first document information with the units included in the second document information on a one-to-one basis according to the degree of relevance; and display combinations of the units in the first document information and the units in the second document information linked with each other.
