Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional systems for providing keywords related to broadcasting content lack the ability to automatically generate keywords with high correlation to the content and viewer interests, relying on manual collection which is inefficient and limited in scope.

Innovation Solution

A system and method that classify prospective viewers based on seed keywords and generate recommendation keywords by selecting keywords with higher correlation to the content from search queries, using a database to store and synchronize keywords with each content's play time period.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual collection and provision of complementary information by an administrator is used, then the system can provide information that is previously prepared and stored, but it is impossible to provide information highly relevant to various broadcasting contents and the amount of information provided is very restricted

Engineering Contradiction:

Improverelevance of information to contentVSAvoidamount of information provided

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system enables automatic collection and generation of keywords through the keyword collection unit and keyword generating unit, eliminating the need for manual administrator input. The system self-organizes and processes broadcasting content to generate relevant keywords automatically, thereby increasing both the quantity and relevance of information provided without manual intervention

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of administrator-based keyword collection is replaced with an automated information processing system that uses the keyword collection unit to gather data from multiple sources and the keyword generating unit to automatically generate relevant keywords through systematic analysis of broadcasting content

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If various search keywords are set manually for a specific content, then the administrator can prepare complementary information, but there is a limit to setting the various search keywords manually and the relevant information selected may not match viewer interests

Engineering Contradiction:

Improveease of keyword preparationVSAvoidadaptability to viewer interests

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The system incorporates a feedback mechanism where the keyword correlation determining unit analyzes the relationship between generated keywords and actual viewer search behavior. This feedback loop allows the system to continuously optimize keyword selection based on viewer interests and search patterns, enhancing adaptability while maintaining ease of operation

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The keyword generation system is dynamic and adaptable, automatically adjusting keyword selection based on viewer behavior patterns and search trends. The system evolves its keyword choices over time to better match viewer interests without requiring manual reconfiguration, making it both easy to operate and highly adaptable

Inventive Principle:

Principle #15Dynamics

3Force

If keywords are synchronized and provided by manually preparing them in advance together with the broadcasting program, then the information can be prepared beforehand, but the technology cannot satisfy the viewers' interests

Engineering Contradiction:

Improvepreparation efficiencyVSAvoidsatisfaction of viewer interests

Core Design Contradiction:

ForceVSReliability

Solution Approach 1:

The manual preparation process is completely replaced with automated systems that collect, analyze, and generate keywords programmatically. The keyword collection unit automatically gathers data from multiple sources, and the keyword generating unit systematically processes this data to create relevant keywords that satisfy viewer interests without manual intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs self-service by automatically generating and synchronizing keywords with broadcasting content without requiring administrator input. The keyword synchronization unit automatically aligns generated keywords with program timelines, enabling efficient preparation that adapts to viewer interests through automated analysis of search behavior and content patterns

Inventive Principle:

Principle #25Self-service

AI summary

There is provided a system and method for providing a recommendation keyword having a high correlation with the content and reflecting the viewers' interests. A prospective viewer group of the content is generated by a broadcast time and a keyword of a specific broadcast content and a keyword set is generated by selecting keywords having a higher correlation with the content than a threshold value from among search words transmitted by the prospective viewer for a predetermined time period including a time before/after the broadcast time of the content. A keyword for each play time period is extracted from the keyword set by using the number of searches for each keyword therein for each play time period and the recommendation keyword for each play time period is stored, which is synchronized with play time of the content.
