Tutorial Dialogue in DiBEx

Computational Linguistics, University of Zurich, Switzerland

A dialogue-based explanation facility for Intelligent CALL (ICALL) Systems is introduced. Our prototype system, DiBEx, uses meta reasoning to build up an explanation (error) tree, given a faulty user input. It relies on correct grammar sub theories, instead of explicit error taxonomies. The system enters in a tutorial dialogue with the student, where each explanation step is based on the principles of a single tutorial strategy. DiBEx focuses on the representation and utilization of grammatical knowledge to participate in such dialogues. Grammar theory is realized as an executable logical theory.
