Dialogue Systems 2 GSLT Spring 2003

Purpose The purpose of the course is to –do real research on dialogue systems by –building on existing systems developed by researchers involved in GSLT. Implementation work is encouraged, as is research that directly contributes to existing systems and projects.

Contents The course will be primarily based on student research projects, supervised locally. Researchers from Göteborg, Linköping and KTH will present their dialogue systems, related research results, and current research topics. On the basis of these presentations, students select a research topic –either one suggested by the lecturers, or –some other improvement or development of an existing system.

Göteborg TrindiKit –a toolkit for building and experimenting with dialogue systems using the information state approach –developed in the TRINDI and SIRIDUS projects, GoDiS –a dialogue system built using TrindiKit and –implementing an issue-based model of dialogue management. Course project types –Adding features to TrindiKit or GoDiS –Building GoDiS applications

KTH Alltiallo (All in one) –Alltiallo has been running for some time and we have papers from different studies and also the platform. HIGGINS - (preliminary title). –The "HIGGINS" project, preliminary title, is still on the drawing board and has no directly relevant literature. The project has so far a focus on error handling in dialog systems.

Linköping tools and frameworks on nlpFarm –for iterative development of dialogue systems. a method for customising a dialogue systems framework –in our case the LINLIN/MALIN framework, –which advocates incremental addition of dialogue capabilities, as presented in the papers below. Course work can either include –the development of a dialogue system for a new application or –extending and refining current demo systems on nlpFarm.
