Arguing about Trust in Multiagent Systems (bibtex)
by Serena Villata, Guido Boella, Dov M. Gabbay, Leendert van der Torre
Abstract:
Trust in multiagent systems is used for seeking to minimize the uncertainty in the interactions among the agents. In this paper, we discuss how to use argumentation to reason about trust. Using the methodology of meta-argumentation, first we represent the source of the information from which the argument is constructed in the abstract argumentation framework capturing the fact that b is attacked because b is from a particular source s. We show how a source of information can be attacked if it is not evaluated as trustworthy. Second, we provide a fine grained representation of the trust relationships between the information sources in which trust concerns not only the sources but also the single arguments and attack relations the sources propose. Moreover, we represent the evidences in support of the arguments which are put forward by the information sources and the agents can express arguments by referring to other agents' arguments. Meta-argumentation allows us not to extend Dung's abstract argumentation framework by introducing trust and to reuse those principles and properties defined for Dung's framework.
