Grammar-based Dialogue Management Techniques

Abstract:

This article is focused on some of spoken dialogue management techniques, in particular on those widely well known as grammar-based ones. Furthermore, as this article shows, even dealing with such more simple dialogue management techniques, the resulting dialogue manager can be capable to cope with relatively advanced phenomena, as for example the cross-references to historically spoken entities. This article is divided into two parts. In the first one, all three techniques mentioned above are overviewed and compared to each other. The rest of the article describes a dialogue manager, currently being developed at our department as a part of an experimental navigation system. Especially, it is focused on the crucial propositions and background ideas like the structure of manager's internal model of a world (static and dynamic frames and bindings between them) and structure of a dialogue history (history of computer and user's utterances and spoken entities).
