Role-plays for CALL: System Architecture and Resources

We present a system architecture for roleplay-like dialogue exercises for computerassisted language learning (CALL). Our ultimate goal is to (i) provide learners with flexible dialogue exercises which facilitate practising interactive skills in a variety of typical communicative scenarios, and (ii) provide teachers and CALL content developers with an environment which would allow them to create and maintain resources needed for such exercises in an easy way. The modularity of our dialogue exercise architecture is motivated by the envisioned distribution of labour in resources authoring between language experts (linguistic resources) and knowledge engineering experts (domain models for the dialogue scenarios).
