Interest-Based Content Clustering for Personalized Recommendation Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional recommendation systems for multimedia content often fail to effectively target individual user interests, leading to less efficient content discovery and recommendation, as they rely on genre-based classifications that do not account for the nuanced preferences within user communities.
Innovation Solution
An interest-based recommendation system that groups content items into clusters based on user-defined interests, using popularity scores within these clusters to recommend content tailored to individual users, rather than relying solely on community-wide popularity metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If genre-based classification is used for content recommendation, then the system structure is simple and easy to implement, but the recommendation accuracy and user interest targeting are insufficient
Solution Approach 1:
The patent segments content items into multiple interest-based clusters rather than using a single genre classification. Each cluster represents a specific user interest topic, allowing fine-grained differentiation of content recommendations based on individual user preferences within broader categories.
Solution Approach 2:
The patent applies local quality by creating user-specific interest clusters that capture nuanced preferences within broader content categories. Instead of treating all content uniformly by genre, the system identifies and recommends content based on specific local interests detected from user viewing behavior.
2Ease of operation
If community-wide popularity metrics are used, then the recommendation system is simple to operate, but it fails to account for individual user preferences and interests
Solution Approach 1:
The patent implements dynamics by transitioning from static community-wide popularity rankings to dynamic user-specific interest-based rankings. The system continuously updates user interest clusters based on viewing history, adapting recommendations to individual preferences while maintaining simplicity through automated cluster assignment.
Solution Approach 2:
The system performs self-service by automatically learning and adapting to user preferences through viewing history analysis. The interest cluster assignment and popularity scoring occur automatically without requiring manual user input or configuration, maintaining ease of operation while achieving personalized adaptation.
3Adaptability or versatility
If traditional linear content delivery is used, then the content delivery system is simple, but viewers have limited choices and cannot access content on their own terms
Solution Approach 1:
The patent introduces another dimension to content delivery by organizing content not just by genre or popularity but by user-specific interest clusters. This adds a personalized dimension to the traditional linear or categorical delivery model, enabling content to be presented according to individual user interests rather than fixed schedules or categories.
Data Source
AI summary
A set of content items can be accessed by a community of users having a set of interests. A set of interest based clusters for the set of content items correspond to the set of interests. For a user, a recommendation system can determine a group of user interest clusters selected from the set of interest based clusters. A popularity score for each content item of the set of content items with respect to the community of users can be generated, and an interest based popularity score for a content item within the interest based cluster can be generated based on a rank of the content item based on the popularity score of the content item. Recommendation candidates for the user can be generated based on the interest based popularity score of the content item for each content item in the group of user interest clusters.
