Benefit from Rich: Tackling Search Interaction Sparsity in Search Enhanced Recommendation
This research introduces GSERec, a novel approach to enhance search-enhanced recommendation by addressing data sparsity. It leverages User-Code Graphs and message passing to propagate information from users with rich search interactions to those with sparse search behaviors. The method uses LLMs for preference summarization, vector quantization for discrete codes, and contrastive learning to improve user similarity modeling. Experimental results demonstrate GSERec's superior performance, especially for users with limited search activity, offering significant improvements over existing recommendation and search-enhanced recommendation models.

Your GSERec Implementation Roadmap
A typical integration of GSERec involves several key phases, designed for minimal disruption and maximum impact.
Phase 01: Data Assessment & LLM Integration
Evaluate existing S&R data, identify sparse interaction patterns, and integrate LLMs for initial user preference summarization. This includes fine-tuning LLM prompts for optimal data extraction.
Phase 02: User-Code Graph Construction
Develop and optimize the vector quantization models (RQ-VAE) to generate discrete user codes. Construct bipartite user-code graphs to establish connections between similar users.
Phase 03: Message Passing & Model Training
Implement message passing on the user-code graphs to enhance sparse user embeddings. Train the GSERec model with contrastive learning objectives to refine user similarity modeling and integrate with downstream recommendation tasks.
Phase 04: Deployment & Monitoring
Deploy the GSERec model into your live recommendation system. Continuously monitor performance metrics, especially for sparse interaction users, and iterate on model improvements.
