Abstract

Trust minimizes the uncertainty in the interactions among the information sources. To express the possibly conflicting motivations about trust and distrust, we reason about trust using argumentation theory. First, we show how to model the sources and how to attack untrustworthy sources. Second, we provide a focused representation of trust about the sources in which trust concerns not only the sources but also the information items and the relation with other information.
