Dynamic intention structures for dialogue processing


We examine personal assistance dialogues and argue that some form of constraint relaxation is necessary during discourse segmentation as often only a subset of the constraints present in the intentional structure reflecting earlier parts of a dialogue can be satisfied in the context of a new utterance. We apply a formal representation of intention that is sufficiently fine-grained to support the revision of structured and evolving propositional content that leads to a more flexible discourse segmentation process. The approach provides a bridge between models of rational agency, plan based models of dialogue and theories of dynamic discourse semantics.
