Employing Context Information and Semantics to Advance Responsiveness in Service Composition
Carsten Jacob, Heiko Pfeffer, Stephan Steglich · IGI Global eBooks · 2009
The idea of context-aware services has been around for a long time. The rise of user mobility enabled by well-equipped mobile devices, increasing interconnectedness and available service platforms such as the mobile Web offers new possibilities for context-aware computing, but, at the same time, produces a number of novel challenges. In this chapter, the authors observe current approaches in this active research area, and identify the respective challenges, achievements, and trends. The authors also extend the notion of context-aware services by considering service composition approaches, and present a middleware aiming at the autonomic and context-aware provision of services in mobile peer-to-peer networks. In this regard special attention is paid to a semantic blackboard concept to cache and disseminate context data and a context-aware service composition approach in terms of the identified trends and challenges.
