Information Search System With Correlative Narrowing Keywords
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information search systems face inefficiencies in identifying desirable information from large datasets due to the sheer number of search results generated when using keywords with similar meanings, making it time-consuming to find relevant information.
Innovation Solution
An information search system that includes a database and an information management device capable of receiving a query, presenting narrowing keywords with correlative relations, and executing searches based on both the input keyword and selected narrowing keywords, thereby reducing the number of search results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a search is executed using an entered keyword and words with similar meanings, then the search comprehensiveness is improved, but the number of search results becomes enormous
Solution Approach 1:
The patent segments the search process into multiple stages: initial broad search using the entered keyword and similar meaning words, followed by a refinement stage where classification information is applied to divide and organize the search results into manageable categories, thereby reducing the overwhelming quantity of results while maintaining search comprehensiveness
Solution Approach 2:
The patent introduces a new dimension of classification information (categories, types, or groups) to organize search results. This adds a structural layer to the search results, transforming a flat list of numerous results into a hierarchical organization that makes it easier to navigate and identify desirable information without reducing the comprehensiveness of the search
2Measurement precision
If classification information is applied to narrow down search results, then the search precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent applies preliminary action by automatically applying classification information to search results before the user needs to review them. The system pre-organizes results into categories based on the entered keyword and similar meaning words, so that when users view the results, the work of organization has already been done, maintaining ease of operation while achieving search precision
Solution Approach 2:
The system performs self-service by automatically categorizing and organizing search results using classification information without requiring manual user intervention. The classification process happens autonomously based on the search query and stored classification data, improving search precision while keeping the user interface simple and easy to operate

AI summary
An information search system includes: a database configured to store service support information; and an information management device configured to search for predetermined information from the service support information, the information management device including a processor configured to receive an input of a query including a keyword, from a searcher, receive an input of classification information to which a narrowing keyword belongs, present a narrowing keyword belonging to the input classification information and having a correlative relation with the keyword, in a selectable manner, and execute a searching process across the database, based on the input keyword and the selected narrowing keyword.
