This paper describes a system for managing dialogue in a natural language interface. The proposed approach uses a dialogue manager as the overall control mechanism. The dialogue manager accesses domain independent resources for interpretation, generation and background system access. It also uses information from domain dependent knowledge sources, which are customized for various applications....

Spoken language dialogue is a comfortable form of communication between humans and computers, which is present in a growing number of commercial systems. For each task which can be comfortably performed in spoken language dialogue with the computer, there is an equivalence class of tasks which can be performed using similar dialogue management technology. Each such task class has a number of mi...

The paper presents principles of dialogue co-operativity derived from a corpus of task-oriented spoken human-machine dialogue. The corpus was recorded during the design of a dialogue model for a spoken language dialogue system. Analysis of the corpus produced a set of dialogue design principles intended to prevent users from having to initiate clarification and repair meta-communication which t...

Why do few working spoken dialogue systems make use of dialogue models in their dialogue management? We find out the causes and propose a generic dialogue model. It promises to bridge the gap between practical dialogue management and (pattern-based) dialogue model through integrating interaction patterns with the underling tasks and modeling interaction patterns via utterance groups using a hig...

As speech and natural language processing technology advance, it now reaches a stage where the dialogue control or initiative can be studied to realise usable and friendly human computer interface programs such as computer dialogue systems. One of the major problems concerning dialogue initiative is who should take the dialogue initiative when. This thesis tackles this dialogue initiative probl...

A spoken dialogue system (SDS) is a specialised form of computer system that operates as an interface between users and the application, using spoken natural language as the primary means of communication. The motivation for spoken interaction with such systems is that it allows for a natural and efficient means of communication. It is for this reason that the use of an SDS has been considered ...
