Terá lugar no próximo dia 20 de fevereiro de 2015, pelas 14h, na sala 0.65 do INESC-ID, Campus do Taguspark, a palestra intitulada
"Non-cooperative and Deceptive Dialogue"
apresentada pelo Prof. David Traum do Institute for Creative Technologies (ICT) at the University of Southern California
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. Theseinclude "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.
David Traum is the director of Natural Language Research at the Institute for Creative Technologies (ICT) and a Research Faculty member of the Department of Computer Science at the University of Southern California (USC). He leads the Natural Language Dialogue Group at ICT, which currently consists of seven Ph.D.s, five students, and two other researchers. More information about the group can be found here
Traum’s research focuses on Dialogue Communication between Human and Artificial Agents.He has engaged in theoretical, implementational and empirical approaches to the problem, studying human-human natural language and multi-modal dialogue, as well as building a number of dialogue systems to communicate with human users. Traum has authored over 200 refereed technical articles, is a founding editor of the Journal Dialogue and Discourse, has chaired and served on many conference program committees, and is a past President and current board member of SIGDIAL, the international special interest group in discourse and dialogue.Traum earned his Ph.D. in Computer Science at the University of Rochester in 1994.
