Query: Evaluating Reputation Systems for Agent Mediated e-Commerce   Agent mediated e-commerce involves buying and selling on Internet through
software agents. The success of an agent mediated e-commerce system lies in the
underlying reputation management system which is used to improve the quality of
services in e-market environment. A reputation system encourages the honest
behaviour of seller agents and discourages the malicious behaviour of dishonest
seller agents in the e-market where actual traders never meet each other. This
paper evaluates various reputation systems for assigning reputation rating to
software agents acting on behalf of buyers and sellers in e-market. These
models are analysed on the basis of a number of features viz. reputation
computation and their defence mechanisms against different attacks. To address
the problems of traditional reputation systems which are relatively static in
nature, this paper identifies characteristics of a dynamic reputation framework
which ensures judicious use of information sharing for inter-agent cooperation
and also associates the reputation of an agent with the value of a transaction
so that the market approaches an equilibrium state and dishonest agents are
weeded out of the market.
