But what do they mean? : modelling contrast between speakers in dialogue signalled by "but"
Understanding what is being communicated in a dialogue involves determining how it is coherent, that is, how the successive turns in the dialogue are related, what the speakersâ intentions, goals, beliefs, and expectations are and how they relate to each otherâs responses. This thesis aims to address how turns in dialogue are related when one speaker indicates contrast with something in the preceding discourse signalled by âbutâ. Different relations cued by âbutâ will be distinguished and characterised when they relate material spanning speaker turns and an implementation in a working dialogue system is specified with the aim of enabling a better model of dialogue understanding and achieving more precise response generation. A large amount of research in discourse addresses coherence in monologue, and much of it focuses on cases in which the coherence relation is explicitly signalled via a cue-phrase or discourse marker (e.g., âon the other handâ, âbutâ, et cetera) which provides an explicit cue about the nature of the underlying relation linking the two clauses. However despite research on Speech Acts, planning research into speakersâ intentions, and semantic approaches to question-answering
