The Role of Polarity in Inferring Acceptance and Rejection in Dialogue
Julian J. Schlöder, Raquel Fernández · 2014
We study the role that logical polarity plays in determining the rejection or ac-ceptance function of an utterance in dia-logue. We develop a model inspired by re-cent work on the semantics of negation and polarity particles and test it on annota-ted data from two spoken dialogue corpo-ra: the Switchboard Corpus and the AMI Meeting Corpus. Our experiments show that taking into account the relative pola-rity of a proposal under discussion and of its response greatly helps to distinguish re-jections from acceptances in both corpora. 1
