TAILIEUCHUNG - Báo cáo khoa học: "Discourse Processing of Dialogues with Multiple Threads"

In this paper we will present our ongoing work on a plan-based discourse processor developed in the context of the Enthusiast Spanish to English translation system as part of the JANUS multi-lingual speech-tospeech translation system. We will demonstrate that theories of discourse which postulate a strict tree structure of discourse on either the intentional or attentional level are not totally adequate for handling spontaneous dialogues. We will present our extension to this approach along with its implementation in our plan-based discourse processor. We will demonstrate that the implementation of our approach outperforms an implementation based on the strict. | Discourse Processing of Dialogues with Multiple Threads Carolyn Penstein Rosét Barbara Di Eugenio Lori s.

The focus of the work reported here has been to draw upon techniques developed recently in the computational discourse processing community Lambert 1994 Lambert 1993 Hinkelman 1990 developing a discourse processor flexible enough to cover a large corpus of spontaneous dialogues in which two speakers attempt to schedule a meeting. There are two main contributions of the work we will discuss in this paper. From a theoretical standpoint we will demonstrate that theories which postulate a strict tree structure of discourse henceforth Tree Structure Theory or TST on either the intentional level or the attentional level Grosz and Sidner 1986 are not .
