A. Lascarides and N. Asher [2008] Agreement and Disputes in Dialogue, in Proceedings of the 9th SIGDIAL Workshop on Discourse and Dialogue (SIGDIAL), Columbus, pp29--36.
In this paper we define agreement in terms of shared public commitments, and implicit agreement is conditioned on the semantics of the relational speech acts (e.g., Narration, Explanation) that each agent performs. We provide a consistent interpretation of disputes, and updating a logical form with the current utterance always involves extending it and not revising it, even if the current utterance denies earlier content.
