David Traum: “Non-cooperative and Deceptive Dialogue”

April 12, 2013 | Pittsburgh, PA

Speaker: David Traum
Host: Carnegie Mellon School of Computer Science LTI Colloquium

Abstract: Cooperation is usually seen as a central concept in the pragmatics of dialogue.There are a number of accounts of dialogue performance and interpretation that require some notion of cooperation or collaboration as part of the explanatory mechanism of communication (E.g., Grice’s maxims, interpretation of indirect speech acts, etc). Most advanced computational work on dialogue systems has also generally assumed cooperativity, and recognizing and conforming to the user’s intention as central to the success of the dialogue system. In this talk I will review some recent work on modeling non-cooperative dialogue, and the creation of virtual humans who engage in Non-cooperative and deceptive dialogue. These include “tactical questioning” role-playing agents, who have conditions under which they will reveal truthful or misleading information, and negotiating agents, whose goals may be at odds with a human dialogue participant, and calculate utilities for different dialogue strategies, and also have an ability to keep secrets using plan-based inference to avoid giving clues that would reveal the secret.
