Learning dialogue structures from a corpus

This paper demonstrates some aspects of a plan processor which is a subcomponent of the dialogue module of verb-mobil. We describe how we transfer results from the research area of grammar extraction for the semi-automatic acquisition of plan operators for turn classes. We exploit statistical knowledge acquired during learning the grammar and incorporate top down predictions to enhance the correct analysis of turn classes described. A rst evaluation shows a relative recognition rate of around 70% on unseen data.
