This paper describes an abstract model for the semantic level of a dialogue system. We introduce mathematical structures which make it possible to design a semantic-driven dialogue system. We describe essential parts of such a system, which comprise the construction of feature-values relations representing meaning from a given world model, the modeling of the flow of information between the dialogue strategy controller and speech recogniser by a horizon of comprehension and the horizon of recognition results, the connection of these horizons to wordings via utterance-meaning pairs, and the incorporation of new horizons into a state of information. Finally, the connection to dialogue strategy controlling is sketched.
