Syntax, Semantics, and Pragmatics in Concert: An Incremental, Multilevel Approach in Reconstructing Task-Oriented Dialogues

This paper gives an overview of a model for the reconstruction of task-oriented dialogues based on an in teract ive , mult i level parsing formalism. It is applied to route description dialogues. It w i l l be shown, how the pragmatic aspects of such dialogues are taken into account on d i f ferent levels of processing. The approach described is based on an extension of the concept of cascaded ATNs. Furthermore this approach uses knowledge sources (KSs) for every part ic ipant in the dialogue in which knowledge about the world and a partner model is bui ld up during the analysis of a dialogue. These KSs are supplied to the parsing process, as we l l . In this paper special importance is la id on the descript ion of the interact ion and cooperation of the d i f ferent processing components of this formalism.
