Trust and Reputation

The research in the area of computational trust and reputation mechanisms for virtual societies is a recent discipline oriented to increase the reliability and performance of electronic communities by introducing in such communities these well known human social control mechanisms.



Computational trust and reputation systems have been recognized as key factors for successful electronic commerce adoption. These systems are used by intelligent software agents both as a mechanism of search for trustworthy exchange partners and as an incentive in decision-making
about whether or not to honour contracts. Reputation is also used in electronic environments as a trust-enforcing, deterrent, and incentive mechanism to avoid cheaters and frauds. Another area of application in agent technology is teamwork and cooperation.
