A survey on context-aware web service systems

Being context-ware will improve how software adapts to dynamic changes influenced by various factors during the operation of the software. Context-aware techniques have been widely applied in different types of applications, but still are limited to small scale or single-organizational environments due to the lack of well-agreed interfaces, protocols, and models for exchanging context data. Web services technologies can support and simplify the exchange of context information in large scale, multiorganizational environments, thus enable Web services systems to utilize various types of context information to adapt their behaviors and operations to dynamic changes. Until now, an overview of techniques and methods suitable for the development of context-aware Web services is missing. This survey aims at studying and analyzing current techniques and methods for context-aware Web services systems, discussing future trends and proposing further steps on making Web services systems being context-aware.
