This paper describes a dialog management system called MASCOTS which manages a dialog between a user and a problem solving system through spoken Japanese and helps the speech understanding system in its language processing. MASCOTS tries to predict the next user utterance based on the architecture for managing dialog with two stacks and plan information. MASCOTS not only contributes to making language processing efficient, but also works for a problem solving system. MASCOTS identifies the kind of the utterance and standardizes its representation form in place of a problem solving system. In this paper, the architecture of MASCOTS is discussed focusing on the characteristics of dialog and two ways of predicting the next user utterance exchanging the information with the language processing system.
