What can context do for web services?

Academia and industry, with the rapid development of information technologies, are adopting Web services due to their integration capabilities. Web services are being actively used for connecting business processes in business-to-business scenarios. The Web services community uses different languages for specifying Web services composition like BPEL and WSFL. The primary objective of these specification languages is to provide a high-level description of the composition process independent from any implementation details or concern. The need for a common semantics is intensified when Web services participate in the same composition. Web services, to reduce the limitations, must be context-aware, context is the information which characterizes the interactions between humans, applications and the environment. A possible solution to achieving a contextual semantic composition of Web services is built upon the semantic-value concept.
