  abstract = {Autonomous entities in artificial societies are only willing to cooperate
	with entities they trust. Reputation systems keep track of the entities’
	behavior
	and, thus, are a widely used means to support trust formation. In
	a P2P network,
	the reputation system needs to be distributed to the individual entities.
	In previous
	work, we have shown that some of the limitations of distributed reputation
	systems
	can be overcome by making use of hard evidence. In this paper, we
	take this
	idea one step further by deriving beliefs of others’ trustworthiness
	from one’s
	own experiences and the available hard evidence. For this purpose,
	we justify
	why a self-interested autonomous entity may choose to behave according
	to the
	norms of the system designer. As a consequence, the proposed belief
	model does
	not only incorporate behavioral beliefs but also beliefs regarding
	the normativeness
	of an entity. We prescribe how beliefs are revised if new evidence
	becomes
	available. The introduced models for recommendations and belief formation
	enable
	us to prove that self-interested entities always issue truthful recommendations
	regarding transactional behavior. The simulative evaluation shows
	that a
	self-interested entity can be expected to be normative and, thus,
	to comply with
	our system design.},
