English abstract:
Distributed services in a context-awareWeb 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 contextaware
Web service systems is a complex issue. It is related not only to how we represent and transfer context
information among Web services, but also to how we support the context storage, and how we ensure security
and privacy issues of context information. Context coupling techniques forWeb service systems will be different
from that of tightly coupled systems because, with Web service systems, context information is typically shared
across the boundaries of organizations which host Web services. This chapter aims at presenting an overview of
context coupling techniques, their related issues, and their implication for a context-aware Web service system.
Our approach is to study existing techniques implemented in current systems, to present open context coupling
issues in current and future context-aware Web service systems, and to suggest further research directions.
