This paper proposes a new method for dialogue management to be used in an intelligent system for information retrieval. The user and the system are modeled as two separate finitestate automata exchanging information through dialogue, and the system manages the dialogue efficiently by estimating the internal states of the user model. These models are constructed on the basis of analysis of a corpus of simulated dialogues, and the proposed method is evaluated from the point of view of perplexity reduction of language models.
