This paper presents an enhanced model of plan-based dialogue understanding. Most plan-based dialogue understanding models derived from [Litman and Allen, 1987] assume that the dialogue speakers have access to the same domain plan library, and that the active domain plans are shared by the two speakers. We call these features shared domain plan constraints. These assumptions, however, are too strict to account for mixedinitiative dialogues where each speaker has a different set of domain plans that are housed in his or her own plan library, and where an individual speaker's domain plans may be activated at any point in. | Toward a Plan-Based Understanding Model for Mixed-Initiative Dialogues Hiroaki Kitano and Carol Van Ess-Dykemat Center for Machine Translation Carnegie Mellon University Pittsburgh PA 15213 hừoaki@ vaness@ ABSTRACT This paper presents an enhanced model of plan-based dialogue understanding. Most plan-based dialogue understanding models derived from Litman and Allen 1987 assume that the dialogue speakers have access to the same domain plan library and that the active domain plans are shared by the two speakers. We call these features shared domain plan constraints. These assumptions however are too strict to account for mixed-initiative dialogues where each speaker has a different set of domain plans that are housed in his or her own plan library and where an individual speaker s domain plans may be activated at any point in the dialogue. We propose an extension to the Litman and Allen model by relaxing the shared domain plan constraints. Our extension improves 1 the ability to frack the currently active plan 2 the ability to explain the planning behind speaker utterances and 3 the ability to frack which speaker controls the conversational initiative in the dialogue. 1. Introduction In this paper we present an enhanced plan-based model of dialogue understanding that provides a framework for computer processing of mixed-initiative dialogues. In mixed-initiative dialogues each speaker brings to the conversation his or her own plans and goals based on his or her own domain knowledge and which do not necessarily match those of the other speaker even in cooperative situations. Thus mixed-initiative dialogues exhibit a more complicated discourse structure than do dialogues in which a single speaker controls the conversational initiative.
