Dialogue understanding as the planning system with some goals

摘要

In this paper, we propose a dialogue understanding model based on planning system which belongs to the study of computational approach. Planning model regards the utterance as the act, which achieve the speaker's goal. But the speaker has not only one goal which depend on the speaker's task but also another goals which change the hearer or the speaker's propositional attitudes. We assume the speaker has some goals, and consider precondition, constraint, and effect in planning. Then we try to analyze the dialogue that the task is not always definite.
