Title: GoDis-Issue-based dialogue management in a multi-domain, 
multi-language dialogue system

Speaker: Stina Ericsson, Department of Linguistics, Göteborg University, Sweden

Abstract: This talk will describe and demonstrate GoDis (Gothenburg Dialogue
System), an experimental dialogue system utilizing dialogue management based
on Ginzburg's concept of Questions Under Discussion (QUD). GoDis is
implemented using TrindiKit, a tool kit for implementing dialogue move
engines and dialogue systems based on the Information State approach.
While originally built for fairly simple information exchange dialogue,
it is being extended to handle action-oriented and negotiative dialogue.
One of the goals of the information state approach is to encourage modularity,
reusability and plug-and-play. To demonstrate this, GoDis has been adapted 
to several different dialogue types, domains, and languages, including 
information
exchange dialogues in travel agency and autoroute domains, and action-oriented
dialogue when acting as an interface to a mobile phone or VCR. GoDis has
also been enhanced with speech input and output, and is able to switch between
Swedish and English in an ongoing dialogue.
