A generative inquiry dialogue system

The majority of existing work on agent dialogues consid-ers negotiation, persuasion or deliberation dialogues. We focus on inquiry dialogues that allow two agents to share knowledge in order to construct an argument for a specific claim. Inquiry dialogues are particularly useful in coop-erative domains such as healthcare, and can be embedded within other dialogue types. Existing inquiry dialogue sys-tems only model dialogues, meaning they provide a protocol which dictates what the possible legal next moves are but not which of these moves to make. Our system not only includes a general dialogue-game style inquiry protocol but also a strategy, for an agent to use with this protocol, that selects exactly one of the legal moves to make. We propose a benchmark against which we compare our dialogues, be-ing the arguments that can be constructed from the union of the agents ’ beliefs, and use this to define soundness and completeness properties for inquiry dialogues. We show that these properties hold for all well-formed inquiry dialogues in our system. Keywords Argumentation, negotiation, and conflict handling. Com
