TAILIEUCHUNG - Báo cáo khoa học: "A TASK INDEPENDENT ORAL DIALOGUE MODEL"

This paper presents a human-machine dialogue model in the field of task-oriented dialogues. The originality of this model resides in the clear separation of dialogue knowledge from task knowledge in order to facilitate for the modeling of dialogue strategies and the maintenance of dialogue coherence. These two aspects are crucial in the field of oral dialogues with a machine considering the current state of the art in speech recognition and understanding techniques. | A TASK INDEPENDENT ORAL DIALOGUE MODEL Erjc Bilan ge CAP GEMINI NOVATION 118 rue de Tocqueyiilẹ 75017 Paris. France and ỈRISA Lannion e-mail ABSTRACT This paper presents a human-machine dialogue model in the field of task-oriented dialogues. The originality of this model resides in the clear separation of dialogue knowledge from task know -edge in order to facilitate for the modeling of dialogue strategies and the maintenance of dialogue coherence. These two aspects are crucial in the field of oral dialogues with a machine considering the current state of the art in speech recognition and understanding techniques. One important theoretical innovation is that our dialogue model is based on a recent linguistic theory of dialogue modeling. The dialogue model considers real-life situations as our work was based on a real man-machine corpus of dialogues. In this paper we describe the model and the designed formalisms used in the implementation of a dialogue manager module inside an oral dialogue system. An important outcome and proof of our model is that it is able to dialogue on three different applications. 1 Introduction The work presented here is a dialogue model for oral taik oriented dialogues. This model is used and under development in the SUNDIAL ESPRIT project1 whose aim is to develop an oral coopera- . tive dialogue system. Many researchers have observed that oral dialogue is not merely organized as a cascade of adjacency paừs as Schlegoff and Sacks 1973 suggested. Task oriented dialogues have been analyzed from different point of view discourse segmentation Grosz Sidner 1986 exchange segmentation with a triplet organization Moeschler 1989 initiative in dialogue Walker Whittaker 1990 etc. From a computational point of view in task ori- 1 Thia project ia partially funded by the Commiaaion for the European Communities ESPRIT programme aa pro- ject 2218.
