Search Result Correction Using Taboo String Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information provisioning systems face challenges in presenting appropriate search results due to the presence of inappropriate language in product or service descriptions and advertising statements, which can compromise the credibility of the system.
Innovation Solution
An information provisioning device that includes a query reception part, a storage for taboo character strings, an acquisition part, a correction part, and a presentation part, which corrects search results by removing or down-ranking matched information containing inappropriate language, ensuring more relevant search results are displayed to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information provisioning system presents all search results including those with inappropriate language, then the quantity of search results is maximized, but the credibility of the system deteriorates
Solution Approach 1:
The patent extracts and removes matched information containing inappropriate language from the search results. The correction part identifies and extracts problematic content based on taboo character strings, then removes or down-ranks this extracted content to maintain system credibility while preserving acceptable search results.
2Reliability
If the system filters out search results containing inappropriate language, then the credibility of search results is improved, but the quantity of search results decreases
Solution Approach 1:
The patent changes the ranking parameter of matched information containing inappropriate language rather than completely removing it. The correction part modifies the display order parameter, down-ranking problematic results while maintaining their availability in the search database, thus balancing credibility improvement with result quantity preservation.
3Manufacturing precision
If the information provisioning device processes and corrects all search results, then the quality of search results is improved, but the calculation workload increases
Solution Approach 1:
The patent performs preliminary action by pre-storing taboo character strings and their associated identification information in the storage part before search operations. This preliminary preparation allows the correction part to quickly identify and process inappropriate content during search result generation, reducing real-time calculation workload while maintaining high result quality.
4Measurement precision
If the system stores detailed taboo character strings and identification information, then the accuracy of filtering inappropriate content is improved, but the storage requirements increase
Solution Approach 1:
The patent uses copying by storing identification information (such as IDs or keywords) that represent taboo character strings, rather than storing complete copies of all inappropriate content. This approach maintains high detection accuracy through precise identification while minimizing storage requirements by storing only essential identifying data.

AI summary
An information provisioning device (12) presents more appropriate search results to the user while using an existing search function. A storage part (206) stores taboo character strings for identification information of a search target and stores identification information as one of those already searched or already selected by the user in the past. An acquisition part (202) acquires search results consisting of matched information containing identification information of a search target satisfying the query. A correction part (203) corrects the search results in regard to matched information based on whether a taboo character string for the identification information is contained in the query. A presentation part (204) presents the corrected search results to the user. A selection reception part (207) receives a command to select matched information from the user.
