Trust-Based Recommendation System Using Segmented Social Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Social networks are difficult to employ effectively due to time constraints, making it inefficient for individuals to seek information and recommendations from trusted friends, as addressing multiple contacts can be time-consuming and unsustainable.
Innovation Solution
A trust-based recommendation system that analyzes aggregate opinions of users in a social network, using an analysis component to provide personalized recommendations based on declared trust relationships and voting behavior, aggregating positive and negative votes into a single opinion, and employing machine learning to infer relationships and trends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If individuals contact every person they have a relationship with to search for information, then comprehensive information can be obtained, but it becomes highly time-consuming and unsustainable
Solution Approach 1:
The patent segments the social network into trust-based clusters or communities around each user, rather than treating the entire network as a single search space. This allows information gathering to be focused on relevant segments (trusted contacts and their trusted contacts) rather than all possible contacts, reducing time while maintaining information quality
Solution Approach 2:
The patent introduces intermediaries (trusted friends or connectors) who can provide information about items or opportunities on behalf of the user. These intermediaries act as mediators between the user and the broader network, allowing information to be obtained without directly contacting everyone in the network
2Ease of operation
If individuals create a massive mailing list of friends to make searching easier, then information access is improved, but the behavior becomes highly antisocial and unsustainable
Solution Approach 1:
The patent applies local quality by making the mailing list dynamic and personalized for each user based on their specific trust relationships and the information they are seeking. Rather than a static universal list, each user has a customized list of relevant contacts, making the system adaptable to individual needs while maintaining social appropriateness
Solution Approach 2:
The patent makes the contact list dynamic rather than static. The system automatically updates which contacts are relevant based on changing trust relationships, user preferences, and information needs. This dynamic adaptation allows the system to remain socially sustainable while maintaining ease of information access
3Reliability
If trust relationships are leveraged for recommendations, then recommendation quality is improved, but system complexity increases due to analyzing trust networks and aggregate opinions
Solution Approach 1:
The patent performs preliminary actions by pre-computing and storing trust metrics, influence scores, and relationship strengths in the database before they are needed for recommendations. This pre-processing reduces the complexity of real-time recommendation generation, as the system can query pre-computed data rather than analyzing entire trust networks from scratch each time
Data Source
AI summary
Systems and methods that analyze aggregated item evaluation behavior of users, to suggest a recommendation for the item. An analysis component forms a collective opinion by taking as input votes of users and trusted relationships established therebetween, to output an evaluation and/or recommendation for the item. Accordingly, within a linked structure of nodes, personalized recommendations to users (e.g., agents) are supplied about an item(s) based upon the opinions/reviews of other users, and in conjunction with the declared trust between the users.
