New method generates synthetic data for conversational recommender systems

Researchers have developed a method for bootstrapping conversational recommender systems (CRS) without requiring domain-specific dialogue data. This approach generates synthetic conversational supervision using non-conversational signals such as item reviews, metadata, and user-item interactions. The study found that this synthetic data consistently outperforms zero-shot prompting and basic synthetic baselines, with active selection strategies improving data efficiency over random sampling. The findings suggest that non-conversational domain signals offer a practical way to build CRS, even in low-resource scenarios. AI

IMPACT Enables the development of conversational recommender systems in domains lacking dialogue data.
