  2. Goteborg University Dialogue Systems Lab GoDiS • A dialogue system built using TrindiKit and based on the information state approach • Implements a theory of Issue-based Dialogue Management • Some goals with GoDiS: • Provide a domain-independent theory covering several dialogue genres • Modularity and reusability of system components • Enable rapid prototyping of new applications • Focus on dialogue management • ... not much work done on NL processing before TALK

  3. Goteborg University Dialogue Systems Lab GoDiS Highlights • Feedback & grounding • 4-level feedback (perception, semantic understanding, pragmatic understanding, acceptance) • Dialogue structure • user may take intiative at any point & change focus (introduce new question or action) • accommodation & simple plan recognition; user needs not be explicit with what she wants to do • focus shifts explicitly echoed • Action-oriented dialogue • menu-based dialogue plans • interaction with external device

  4. Goteborg University Dialogue Systems Lab GoDiS VCR • GoDiS application for programming a VCR over the telephone • schedule recordings • remove planned recordings • TV card used for recording television programs as video files • Small corpus collected of users calling the system • approx. 100 sessions (calls) and 1100 utterances • misrecognised utterances not yet transcribed • GUI enables immediate access to corpus
