Context Coupling Techniques for Context-Aware Web Service Systems - An Overview

Distributed services in a context-aware Web service system or in a service composition need to couple context information from different sources in order to be able to interpret context information. Such interpretation is a prerequisite before services can adapt themselves to be context-aware. However, context coupling in context-aware Web service systems is a complex issue. It is related not only to how people represent and transfer context information among Web services, but also to how they support the context storage, and how they ensure security and privacy issues of context information.
