Researchers have developed a new framework called COPE (COnversational Preference Elicitation via Mixture of Experts) to improve conversational recommender systems. This system dynamically adjusts its preference elicitation strategies based on the stage of the conversation. Early in a dialogue, COPE favors attribute-based inquiries, while later stages benefit more from item-based strategies. The effectiveness of this approach was demonstrated through offline evaluations using a newly created dataset, InPE, which includes detailed annotations for elicitation necessity and strategy selection.
