@conference {IIIA-2007-1287, title = {Information-Based Agency}, booktitle = {Twentieth International Joint Conference on AI, IJCAI-07}, year = {2007}, pages = {1513-518}, publisher = {AAAI Press}, organization = {AAAI Press}, abstract = {Successful negotiators look beyond a purely utilitarian view. We propose a new agent architecture that integrates the utilitarian, information, and semantic views allowing the definition of strategies that take these three dimensions into account. Information-based agency values the information in dialogues in the context of a communication language based on a structured ontology and on the notion of commitment. This abstraction unifies measures such as trust, reputation, and reliability in a single framework.}, author = {Carles Sierra and J. Debenham} }
