Abstract:
The emergence of semantic overlay networks as
instruments to improve security, trust and stability in distributed
virtual communities is recognized widely in the research
community. We propose a fuzzy logic based framework which
integrates social information such as trustworthiness, reputation
and credibility ratings for individuals, alliances, organizations,
services and products in e-commerce markets. This framework is
designed to support the decision making process of autonomous
agents during the selection of the optimal business partner. Fuzzy
systems provide the ideal capabilities to process multiple criteria,
which are composed of imprecise information and attribute
definitions expressed in natural language. The proposed fuzzy
models implement the DEco Arch framework and ontologies
which provide details about concepts and their relationships in
virtual communities.
