Plans in natural-language dialogues

摘要

This paper suggests reflecting the ‘state of mind’ of participants in conversation by viewing plans as a kind of mental structure, a structure that takes into account and affects such mental states as beliefs, commitments and intentions. A formal method is described for computing the construction and the reconstruction of mental plans. Plan reconstruction is then used in the context of the man-machine interface to (a) model topic structure, (b) generate appropriate responses when agents use speech acts, and (c) respond to queries that result from an invalid plan.
