Extended Keyword Pool Search System for Enhanced Result Variety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional search methods are limited by relying solely on purchase history-based keyword sets, leading to a reduced ability to search for desired keywords and a lack of variety in search results.
Innovation Solution
A search system using an extended keyword pool that combines purchased keyword sets with additional keywords from various sources, such as news, blogs, and shopping queries, to generate a unified search keyword set, allowing for a broader range of keywords with high association or novelty scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the keyword pool is simply increased, then more keywords may be searched, but the probability to search for the keyword that a user may desire to search is reduced
Solution Approach 1:
The patent segments the keyword pool into multiple distinct sets: purchased keyword sets (from search advertisements), additional keyword sets (from various sources like news, blogs, shopping), and unified search keyword sets. This segmentation allows the system to manage and weight different keyword sources separately, maintaining search accuracy while expanding overall keyword coverage.
Solution Approach 2:
The patent changes parameters by introducing association scores and novelty scores to evaluate and weight keywords from different sets. By adjusting these scoring parameters, the system can prioritize high-quality keywords while still incorporating the expanded keyword pool, thus maintaining search precision despite increased keyword quantity.
2Ease of operation
If only purchase history-based keyword sets are used, then the search system is simple to operate, but the ability to search for more various keywords is limited
Solution Approach 1:
The patent merges multiple keyword sources including purchased keyword sets, additional keyword sets from various external sources (news, blogs, shopping), and unified search keyword sets into a single integrated keyword pool. This combination maintains operational simplicity while significantly expanding keyword variety and search versatility.
Solution Approach 2:
The search system is designed to handle multiple types of keyword sets uniformly through a single search interface. The system can process purchased keywords, additional keywords from various sources, and unified search keywords all through the same operation mechanism, achieving multi-functionality without compromising ease of use.
3Quantity of substance
If keywords from multiple sources are combined, then a large range of keywords is provided, but the complexity of the search system increases
Solution Approach 1:
The patent applies preliminary action by pre-processing and organizing keywords from multiple sources into distinct sets before they are used in searches. The system pre-calculates association scores and novelty scores for keywords, and pre-unifies search keywords, thereby reducing the complexity during actual search operations while maintaining a large keyword range.
Data Source
AI summary
A search system using an extended keyword pool includes a processor. The processor includes a purchased keyword module configured to generate a purchased keyword set by searching for a keyword having a purchase history through a search advertisement. The processor includes an additional keyword module configured to generate an additional keyword set by extracting a keyword from at least one source. The processor includes a unified search keyword module configured to generate a unified search keyword set by searching for a keyword having a number of hits greater than a determined number of hits among queries comprising the purchased keyword set and the additional keyword set. The processor includes a search module configured to provide, as a keyword pool, an associated keyword or an extended keyword with respect to a search word, using the keywords in the purchased keyword set, the additional keyword set, and the unified search keyword set.
