Pearl: A Review-driven Persona-Knowledge Grounded Conversational Recommendation Dataset (2403.04460v4)
Published 7 Mar 2024 in cs.CL
Abstract: Conversational recommender system is an emerging area that has garnered an increasing interest in the community, especially with the advancements in LLMs that enable diverse reasoning over conversational input. Despite the progress, the field has many aspects left to explore. The currently available public datasets for conversational recommendation lack specific user preferences and explanations for recommendations, hindering high-quality recommendations. To address such challenges, we present a novel conversational recommendation dataset named PEARL, synthesized with persona- and knowledge-augmented LLM simulators. We obtain detailed persona and knowledge from real-world reviews and construct a large-scale dataset with over 57k dialogues. Our experimental results demonstrate that utterances in PEARL include more specific user preferences, show expertise in the target domain, and provide recommendations more relevant to the dialogue context than those in prior datasets.
