Speech Actions and Mental States in Task-Oriented Dialogues

Peter Heeman

In this paper, we propose a set of speech actions to account for how conversants collaborate in building a domain plan. The actions that we propose are indexical on the current plan, which is part of the mental states of the conversants. The current plan not only includes the actions that have been proposed to solve the problem, but also beliefs about the plans validity and how each action contributes to the overall goal of the plan. The intended effects of the actions are that the current plan is updated.
