We call these dialogues SingleInitiative Dialogues. In modeling single-initiative dialogues, Litman and Allen assume a shared stack that represents ajointplan (joint domain plan). This joint plan is shared by the two speakers. We claim that this assumption is too restrictive to apply to mixedinitiative dialogues, because in mixed-initiative dialogues each speaker may have his or her own individual domain plans I. The assumption creates several functional problems in the Litman and Allen model, namely, its inability to process mixed-initiative dialogues and the need for a large amount of schema definition (domain knowledge representation) to handle complex conversational interactions. The model we present builds on the framework of [Litman and Allen, 1987]. We hypothesize, however, that spe...
