Towards Conversational Recommender Systems: A Dialogue Grammar Approach.
Derek Bridge · 2002
We highlight the importance of dialogue management in systems that support mixed-initiative interaction. For concreteness, we focus on interaction with recommender systems. We propose an approach that uses both a dialogue grammar and a recommendation strategy. The dialogue grammar makes explicit the opportunities the user and system have for seizing and ceding the initiative. But it maintains only local dialogue coherence. The recommendation strategy is used to achieve global dialogue coherence.
