Cooperating to Be Noncooperative: The Dialog System PRACMA

The modeling of noncooperative dialogs, as opposed to dialogs in which the goals of the participants coincide, presents novel challenges to a pragmatically oriented dialog system. PRACMA models noncooperative sales dialogs. In the role of the potential buyerof a usedcar, the system tries to arrive at a realistic evaluation of the unknown car in spite of biased information presentation on the part of the seller. In the role of the seller, PRACMA tries to form a usable model of the buyer even while using this model to manipulate the buyer's impressions. To realize this behavior, heterogeneous modules and representation formalisms cooperate within a multi-agent architecture.
