We study the role that logical polarity plays in determining the rejection or acceptance function of an utterance in dialogue. We develop a model inspired by recent work on the semantics of negation and polarity particles and test it on annotated data from two spoken dialogue corpora: the Switchboard Corpus and the AMI Meeting Corpus. Our experiments show that taking into account the relative polarity of a proposal under discussion and of its response greatly helps to distinguish rejections from acceptances in both corpora.
