Quality Over Clicks: Iterative Reinforcement Learning for Early-Stage E-Commerce Query Suggestion
Researchers have developed QualEQS, a novel framework for improving e-commerce query suggestions in early-stage deployment scenarios where click data is scarce. This quality-first iterative reinforcement learning approach focuses on answerability, factuality, and information gain, rather than solely relying on click-through rates. The system identifies ambiguous contexts and difficult training cases through group-level disagreement among suggestions, leading to a 6.81% improvement in online performance in a real-world conversational shopping assistant.
