A Broker Agent In The Semantic Web Services Environment
Önder Gürcan · DergiPark (Istanbul University) · 2011
Brokers are one of the main discovery and synchronization mechanisms among autonomous agents. Because of their mediation and coordination properties as well as wide applicability, brokers are a natural candidate component for the semantic services environment. In this paper, design considerations of a broker agent in the semantic services environment which is based on the SWSA abstract architecture are discussed. Main focus of its design is to provide flexible and reusable broker architecture conforms to this abstract architecture. SWSA defines three consecutive phases for service usage: discovery, engagement and enactment. Each phase includes different activities to satisfy internal requirements of that phase. The critical point here is that each activity can be implemented in a different way based on the application requirements. In this context, our broker agent provides such a flexible architecture in which different implementations of activities can be plugged-in to the system easily.
