Abstract
The growing popularity of multi-agent based
approaches towards the formation and operation of virtual
organizations (VO) present over the Internet, offer both
opportunities and risks. One of the risks involved in such
community is in the identification of trustworthy agent partners
for transaction. In this paper we aim to describe our trust model
which would contribute in measuring trust in the interacting
agents. Named as TruMet, the trust metric model works on the
basis of the parameters that we have identified as relevant to the
features of the community. The model primarily analyses trust
value on the basis of the agent¿s reputation, as provided by the
agent itself, and the agent¿s aggregate rating as provided by the
witness agents. The final computation of the trust value is given
by a weighted average of these two components. While
computing the aggregate rating, a weight based method has been
adopted to discount the contribution of possibly un-fair ratings
by the witness agents.
