Abstract: In this paper we discuss some requirements on natural language interfaces that are needed for supporting connected dialogue, and propose methods for meeting these requirements in the context of a system that has been developed at our department over the last couple of years. On the basis of data collected in Wizard-of-Oz simulations we argue that the dynamic discourse representation needed for a given application can be structured in terms of a tree of dialogue objects (moves, initiative-response units) and a score board, i.e. a list of parameters each of which keeps some information relevant to the system's interpretation and generation tasks. We also argue that the domain knowledge needed for supporting reference resolution can, and should be obtained from data of this kind.
