A unification of a speech-act oriented model for information-seeking dialogues (cor) with a model to describe the structure of monological text units (rst) is presented. This paper focuses on the necessary extensions of rst in order to be applicable for information-seeking dialogues: New relations are to be defined and basic assumptions of RST have to be relaxed. Our approach is verified by interfacing the dialogue component of an intelligent multimedia retrieval system with a component for natural language generation.
