The thesis describes a logical formalization of natural-language database interfacing. We
assume the existence of a``natural language engine''capable of mediating between surface …

This paper describes a way of using intonation and dialog context to improve the
performance of an automatic speech recognition (ASR) system. Our experiments were run …

Computational pragmatics and dialogue analysis is currently a rapid growing area of
research in computational linguistics. Over the past five years or so, initiatives in modelling …

A spoken dialog system is a computer system that interacts with a user via natural spoken
language to help the user obtains desired information or resolves a problem. As for current …

The paper1 uses a simple and abstract characterization of dialogue in terms of mental state
changes of dialogue participants to raise three fundamental questions for any theory of …

Before a system can be formally defined, it is common to write a specification in a natural
language as the basis for the formal definition. Natural languages are not well suited for this …

Many of the kinds of language model used in speech understanding suffer from imperfect
modeling of intra-sentential contextual influences. I argue that this problem can be …

We look at the effect of using high level discourse knowledge in dialogue act type detection.
We also look at ways this knowledge can be used for improving language modelling and …

This paper discusses the use ofconversational'ordialogue games' as a basis for building
dialogue systems. We give a tutorial overview of some recent attempts to relate the notion of …
