Abstract

Trust and reputation systems represent a signifcant trend in
decision support for Internet mediated service provision.
The basic idea is to let parties rate each other, for
example after the completion of a transaction, and use the
aggregated ratings about a given party to derive a trust or
reputation score, which can assist other parties in deciding
whether or not to transact with that party in the future. A
natural side effect is that it also provides an incentive
for good behaviour, and therefore tends to have a positive
effect on market quality. Reputation systems can be called
collaborative sanctioning systems to reflect their
collaborative nature, and are related to collaborative
filtering systems. Reputation systems are already being used
in successful commercial online applications. There is also
a rapidly growing literature around trust and reputation
systems, but unfortunately this activity is not very
coherent. The purpose of this article is to give an overview
of existing and proposed systems that can be used to derive
measures of trust and reputation for Internet transactions,
to analyse the current trends and developments in this area,
and to propose a research agenda for trust and reputation
systems.
