This paper proposes a multi-type context-aware conversational recommender system (MCCRS) that effectively integrates various types of contextual information to improve the performance of conversational recommender systems. MCCRS integrates both structured and unstructured information, including structured knowledge graphs, unstructured conversation transcripts, and unstructured product reviews. Each expert specializes in a specific contextual information (structured knowledge graphs, conversation transcripts, and product reviews), and ChairBot coordinates multiple experts to produce the final result. Experimental results demonstrate that MCCRS significantly outperforms existing baseline models.
