Media Query Identification via Keyword Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current search engines lack the ability to effectively identify and provide specialized results for media-related queries, leading to irrelevant or unspecific search outcomes when users seek information about media items like movies, books, or video games.
Innovation Solution
A system and method that involve creating keyword lists for different media categories, identifying search queries as media queries by matching them against these lists, and providing specialized result documents based on the identified media type, utilizing a products search index and candidate queries to determine the relevance of the query to specific media categories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a general products search index is used for all queries, then the system maintains simplicity and broad coverage, but the search results become irrelevant or unsspecific for media-related queries
Solution Approach 1:
The patent segments the search system by creating separate keyword lists for different media categories (movies, books, music, video games). This segmentation allows the system to apply category-specific matching logic to identify media queries, thereby improving search result relevance without requiring a complete restructuring of the search infrastructure.
Solution Approach 2:
The patent introduces an intermediary classification layer that sits between the general products search index and the final search results. This intermediary uses keyword list matching to determine whether a query is media-related and routes it appropriately, acting as a mediator that enhances relevance without directly modifying the core search index.
2Measurement precision
If the system implements category-specific keyword matching for media queries, then search accuracy for media items improves, but the processing time and computational resources increase
Solution Approach 1:
The patent performs preliminary action by pre-compiling organized keyword lists for each media category before the actual search query processing. This advance preparation allows the system to quickly match queries against structured keyword lists during search operations, reducing the computational burden and processing time during actual query execution while maintaining high identification accuracy.
3Ease of operation
If the system provides specialized result documents for media queries, then user experience and information relevance improve, but the system complexity and development effort increase
Solution Approach 1:
The patent applies local quality by providing specialized result documents only for identified media queries, while maintaining the general products search results for non-media queries. This targeted approach enhances user experience for media-related searches without requiring the entire system to be redesigned, thereby improving ease of operation for specific use cases while limiting the increase in overall system complexity.

AI summary
A computer device obtains a search query; obtains product search results based on the search query and a products search index that includes information regarding documents associated with products; determines a category associated with a set of result of the product search results; identifies candidate queries for the search query; determines whether the category matches one of the candidate queries; identifies that the search query is associated with a type of media identified by the category when the category matches one of the candidate queries; and provides, in response to identifying that the search query is associated with the type of media, a result document based on the type of media.
