A Semantic Approach for Service Adaptation in Context-aware Environment

With pervasive computing, Service oriented architectures become more mobile and distributed and are executed in varying contexts. Context is understood as any information about the user needs and operating environment which vary dynamically and have an impact on design choices. Context aware Services oriented systems have emerged as an underlying design and development paradigm. An important challenge in such systems is context modeling, reasoning and adaptating services behavior. Using ontologies and semantic web services to deal with context aware services has attracted a lot of interest. In this paper, we present an architecture for the development of context aware services based on ontologies. We highlight our context metamodel and discuss about reasoning process. we also present our semantic approach for service adaptation in context aware environment.
