SUMMARY:Representing reputation in a multiagent system
DESCRIPTION:We consider the problem of a multiagent system where entities
 meet and interact in a pairwise fashion. Agents may rate the outcome of the
 interaction (e.g.\, on a discrete scale). In time\, this allows to build a
 reputation score for each agent. The aim of this talk is to explore how the
 reputation is represented\, using a Bayesian approach\, in the Beta and
 Dirichlet reputation systems. The Dirichlet reputation system is the
 foundation of Subjective Logic\, which is a probabilistic logic system that
 allows to explicitly represent uncertainty along with beliefs. Subjective
 logic\, which provides among other things a formalism to treat transitivity
 of trust\, is very useful in the representation of trust networks.\n\n[1]
