DEco Arch: Trust and Reputation Aware Service Brokering Architecture in Digital Ecosystems

Abstract

Awareness of social ratings such as reputation, credibility and trustworthiness plays a key role in digital ecosystems where autonomous agents collaborate in order to publish their services or search for services. The integration of these social ratings along with attribute matching presents a novel approach and strengthens stability and confidence in autonomous distributed communities. This ensures that the selection of the optimal service is guaranteed while minimizing general security and business related risks. In this paper we discuss a framework for service registration which is hosted in a P2P environment. Service consumers can discover services which are grouped based on their contexts. Both, services and group alliances are defined through semantically enriched metadata and social ratings.
