New framework enhances e-commerce semantic search relevance

A new research paper introduces "Mine and Refine," a two-stage contrastive training framework designed to improve semantic search retrieval in e-commerce. This method addresses challenges such as noisy engagement signals, difficulties in mining hard negative samples, and unstable similarity score separation across different relevance levels. The framework utilizes a lightweight LLM for scalable labeling and employs label-aware supervised contrastive learning and a multi-level extension of circle loss. When deployed in production e-commerce search, the approach demonstrated significant improvements in user engagement, gross order value, and overall relevance metrics. AI

IMPACT This framework could significantly improve the effectiveness and user engagement of e-commerce search systems by refining retrieval accuracy.
