Document Search System Using Phrase Extraction for Similarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patent search platforms face challenges in efficiently providing relevant similar documents to users, often resulting in a large number of irrelevant results and a high burden on users to find the desired information.
Innovation Solution
A document search method that utilizes a user-friendly interface to search for similar documents based on user-input phrases, listing sentences or paragraphs containing similar phrases, and displaying results in a card format for easy navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of similar prior documents are provided to users, then the completeness of search results is improved, but the user burden and time required to find relevant information increases
Solution Approach 1:
The patent segments the large number of similar prior documents into smaller, more manageable units by extracting and displaying specific sentences or paragraphs that contain the search keywords. This segmentation allows users to quickly scan relevant content without being overwhelmed by the full document list, thereby reducing time while maintaining completeness.
Solution Approach 2:
The patent extracts key sentences or paragraphs containing search keywords from the similar prior documents and presents them separately. This extraction approach allows users to directly view the most relevant portions of documents without reading entire documents, significantly reducing the time required to find relevant information while preserving the completeness of search results.
2Reliability
If traditional search result listing is used, then all similar documents can be displayed, but the user interface becomes complex and difficult to navigate
Solution Approach 1:
The patent segments search results into card-type displays showing only specific sentences or paragraphs containing keywords, rather than presenting complete document listings. This segmentation simplifies the interface by showing only the most relevant portions, making navigation easier while maintaining result completeness.
Solution Approach 2:
The patent creates simplified copies of document content by extracting and displaying only the relevant sentences or paragraphs in a card format. These copies present the essential information in a user-friendly manner without requiring users to interact with the full document structure, thereby reducing interface complexity.
3Measurement precision
If comprehensive search algorithms are implemented, then search accuracy is improved, but the system complexity and computational resources increase
Solution Approach 1:
The patent extracts only the necessary portions of documents (sentences or paragraphs containing keywords) for presentation, rather than processing and displaying entire documents. This extraction approach maintains search accuracy by focusing on relevant content while reducing system complexity by minimizing the amount of data that needs to be managed and presented.
