Search Keyword Extension via Concept Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing search and advertisement technologies fail to accurately provide targeted results when search keywords include modifiers and concept keywords, leading to inappropriate search results and advertisements being exposed to non-targeted users, resulting in ineffective advertising and unnecessary expenses.
Innovation Solution
A method and apparatus that divide modifiers and concept keywords from input keywords, using a concept keyword extension dataset to map and extend search keywords, generating final extension keywords that match user intentions by combining modifiers with extended concept keywords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If search keywords are extended to all morphemes including modifiers, then the search coverage is increased, but the search precision deteriorates leading to inappropriate search results
Solution Approach 1:
The patent segments search keywords into two distinct components: concept keywords (core meaning) and modifiers (descriptive attributes). This segmentation allows the system to extend only the concept keywords using association data while preserving the specificity of modifiers, thereby maintaining search precision while improving coverage.
Solution Approach 2:
The patent extracts and separates modifiers from concept keywords in the search query. By taking out modifiers and applying extension only to concept keywords, the system avoids the precision loss that would occur if all keyword components were extended uniformly, thus resolving the contradiction between coverage and precision.
2Quantity of substance
If keyword advertisement is provided based on extended search keywords, then the advertising reach is increased, but the advertising effectiveness deteriorates due to exposure to non-targeted users
Solution Approach 1:
The patent applies segmentation to advertisement targeting by distinguishing between concept keywords (which determine the core advertising message) and modifiers (which define the target audience). Advertisements are extended based on concept keywords while preserving modifier constraints, ensuring broader reach without sacrificing targeting accuracy.
Solution Approach 2:
The patent implements local quality by applying different extension rules to different parts of the keyword structure. Concept keywords receive extension treatment to expand reach, while modifiers maintain their original specificity to preserve targeting quality, thus achieving both extended reach and maintained effectiveness.
3Quantity of substance
If multiple banner advertisements are inserted into limited site space, then the advertising revenue is increased, but the site coherence deteriorates and beauty is damaged
Solution Approach 1:
The patent applies local quality to advertisement content by generating context-specific advertisements tailored to different user search intents. This allows multiple advertisements to be displayed with content that is locally optimized for each user's specific query, maintaining site coherence and user experience while maximizing advertising revenue through targeted placement.

AI summary
Disclosed herein are a method, an apparatus, and a computer readable recording medium for a search using extension keyword. According to an aspect of the present invention, there is provided a method for a search using extension keyword, the method including mapping search keywords transmitted from a user terminal to at least one concept keyword, extending the concept keyword to plurality of concept keywords having association with each other so that a concept keyword extension data-set is generated, and generating extension keywords corresponding to the concept keyword extension data-set.
