Context-Based Reputation Management for Service Composition and Reconfiguration
Jinhwan Lee, Jing Zhang, Zheng-qiu Huang, Kwei-Jay Lin · 2012
Service-Oriented Architecture (SOA) provides a framework for service composition and reconfiguration. In addition to making composition decisions by considering functional attributes, technology for composition by meeting non-functional requirements such as QoS is also needed. In this paper, we present an approach to compose business process by considering context-based service reputation. Since some services may perform well only at specific context, we may use context similarity to filter out those services that are not fit given a user's context. We present the design of a Context Manager which works as part of an SOA middleware to compose and reconfigure services. Simulation results show the effectiveness of our design.
