A Conversational Recommender System (CRS) is defined by Gao et al. (2021) as following:

A recommendation system that can elicit the dynamic preferences of users and take actions based on their current needs through real-time multi-turn interactions using natural language.

Attribute-based CRSs typically capture user preferences by asking queries about item attributes and generates responses using pre-defined templates.

Compared to attribute-based CRSs, generation-based CRSs pay more attention to generate human-like responses in natural language.
