Recognizing plans in more natural dialogue utterances

Kiyoshi Kogure, Akira Shimazu, Mikio Nakano

We propose a dialogue utterance analysis model that treats an utterance as a sequence of acts of uttering its constituent words and constructs plans that connect these acts. In this model, intra-utterance and inter-utterance plan structures are both treated uniformly, implying that the input utterance boundaries do not have to be predetermined. Moreover, this model constructs possible partial plan structures during utterances, making it possible to obtain the information needed to make an adequate response to the input utterance before it has finished. The model can effectively handle fragmental utterances and utterances that are syntactico-semantically ambiguous but pragmatically unambiguous. Based on this model, we have developed an experimental plan-analysis module that parses plan structures by using a constraint-based linguistic framework. This module is used as the pragmatic analysis module of an experimental system for a cooperative distributed natural language understanding model called "Ensemble."
