Seed-Based Ad Matching for Contextual Keyword Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional contextual advertising services are limited in displaying advertising information as they require exact keyword matches within web documents, restricting advertisers who purchased broader keywords from showcasing relevant ads, even when the document context aligns with their offerings.
Innovation Solution
A method and system that utilize a 'seed' concept to identify and display advertising information for multiple advertisers with similar properties by analyzing content page keywords, allowing for the inclusion of advertisers and keywords with shared properties within a single seed, even if the exact keyword is not present in the document.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional contextual advertising services require exact keyword matches within web documents, then advertising display accuracy is improved, but advertiser versatility deteriorates
Solution Approach 1:
The patent segments the advertising matching process into two levels: exact keyword matching for precision and seed-based property matching for versatility. The seed concept divides advertisers and keywords into groups sharing common properties, allowing the system to switch between exact matching (when keywords are present) and property-based matching (when keywords are absent but context aligns), thus resolving the contradiction between accuracy and advertiser versatility
Solution Approach 2:
The patent introduces 'seed' as an intermediary concept between exact keywords and advertising display. The seed represents a group of advertisers or keywords with identical properties and serves as a mediator that enables broader matching beyond exact keywords. When exact keyword matches fail, the seed's associated properties act as an intermediary to still connect relevant advertisers with appropriate content, maintaining versatility without sacrificing accuracy
2Adaptability or versatility
If a single seed includes multiple advertisers or keywords with identical properties, then advertising matching flexibility is improved, but system complexity deteriorates
Solution Approach 1:
The patent makes the seed concept universal by designing it to serve multiple functions: it can represent a group of advertisers, a group of keywords, or both simultaneously. This multi-functionality allows the system to handle diverse matching scenarios using a single unified mechanism, improving flexibility while avoiding the need for separate complex systems for different matching types
Solution Approach 2:
The patent merges the management of multiple advertisers and multiple keywords into a single seed structure. By combining these elements under one seed with shared properties, the system reduces complexity compared to managing each advertiser-keyword pair separately, while still maintaining the flexibility to match based on common properties across multiple entities
3Adaptability or versatility
If keywords are associated with multiple seeds, then keyword versatility is improved, but seed determination accuracy deteriorates
Solution Approach 1:
The patent applies local quality by allowing keywords to have different associations in different contexts. A keyword can be associated with multiple seeds, but the system determines which seed to use based on the local context of the content being analyzed. This context-dependent selection maintains seed determination accuracy while preserving keyword versatility across different scenarios

AI summary
A method of generating an advertising list using a seed, which can include a plurality of advertisers or a plurality of keywords with an identical property in a single seed and thereby can display various types of advertising information of the plurality of advertisers, which are included in the seed, according to a single condition, and an advertising matching system is provided. According to the present invention, it is possible to provided a method of generating an advertising list using a seed, which can determine a property of a content page using a seed, and thereby can display various types of advertising information of a plurality of advertisers with the determined property, as contextual advertising, for a user, and an advertising matching system using the method.
