GoDiS (Gothenburg Dialogue System) is an experimental dialogue system
utilizing dialogue management based on Ginzburg's concept of Questions
Under Discussion (QUD). GoDiS is implemented using the TrindiKit, a
toolkit 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. It has also been enhanced with speech input and output, and
is able to switch languages in an ongoing dialogue. The current range
of applications includes the following:

--information exchange dialogue in travel agency: English
(with speech input/output), Swedish (with speech
input/output), German (with text input/output; speech output
under development), Spanish (with text input/output; speech
output under development)

-- action-oriented dialogue for a mobile phone interface: 
English (with speech input/output), Swedish (with speech
input/output)

-- action-oriented dialogue for a VCR interface:  English
(with speech input/output), Swedish (with speech
input/output)
