Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing keyword search systems do not provide a clear reason for the popularity of keywords in real-time, especially in the context of broadcast information, making it difficult for users to understand why certain keywords are trending.

Innovation Solution

A method and system that generates a representative phrase indicating the reason for a popular keyword's popularity by correlating it with broadcast information, such as airtime, and displays this information on a content providing page.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If keyword search systems display popular keywords, then users can see trending search terms, but users cannot understand the reason for keyword popularity

Engineering Contradiction:

Improvereason for keyword popularityVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces broadcast information as an intermediary element that connects popular keywords to their underlying reasons. The system correlates keywords with broadcast program data (titles, content, airtime) to generate representative phrases that explain why certain keywords are trending, without requiring complex analysis of search behavior patterns

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of information

If the system correlates keywords with broadcast information, then it can provide reasons for keyword popularity, but the processing complexity increases

Engineering Contradiction:

Improvecontext informationVSAvoidprocessing complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts only the essential broadcast information elements needed to explain keyword popularity, such as program titles and key content descriptors. By selectively extracting relevant broadcast data rather than processing all available information, the system provides contextual explanations while maintaining manageable processing complexity

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms broadcast information into standardized representative phrases that correlate with keywords. By changing the parameter representation of broadcast data into structured, comparable formats, the system enables efficient correlation and matching operations without requiring complex processing of raw broadcast content

Inventive Principle:

Principle #35Parameter changes

3Loss of information

If the system generates representative phrases for all popular keywords, then user understanding is enhanced, but the time required for generation increases

Engineering Contradiction:

Improveexplanatory informationVSAvoidgeneration time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary correlation between keywords and broadcast information by pre-processing and indexing broadcast data according to relevant parameters. This preliminary action enables rapid generation of representative phrases when keywords become popular, without requiring time-consuming analysis at the moment of generation

Inventive Principle:

Principle #10Preliminary action

AI summary

Provided is a method and system for providing a representative phrase with respect to a real time popular keyword, which may determine programs including a popular keyword from broadcast information, and may generate a representative phrase with respect to the popular keyword using the determined programs, thereby providing the representative phrase by combining the generated representative phrase and the popular keyword.
