	abstract = {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. (c) 2014 Elsevier B.V.},

	abstract = {An important challenge in pervasive computing environments is to automatically enable software applications by dynamically composing services. Service composition is a way to plan a business process to fulfill business goals that cannot be achieved by individual business services. Given a representation of services in OWL-S, service composition can be modeled as an Artificial Intelligence planning (AI planning) problem. Based on the initial context and the goal context, planning-based service composition launches a goal-oriented composition procedure to generate a plan for the service composition. In this paper, we present an overview of the architecture for the composition of context aware services based on ontologies, we also present our Composition Planner that allows to generate a plan corresponding to the request of the users according to their context.},

	abstract = {The rapid evolution of software paradigms, wireless technologies and mobile devices induced the emergence of new applications called context-aware services oriented applications. Such applications provide appropriate services or relevant information to the user or other applications to perform a specific task. An important challenge in such applications development process is context modeling and reasoning. Ontology based models presents the most promising instrument for context modeling and offers possibility of applying ontology reasoning techniques. the aim of context reasoning is converting low-level context to high-level context in order to provide costumized services to users. In this paper, we present an architecture for the development of context aware services based on ontologies. We also highlight our context metamodel and discuss about reasoning process for e-health systems.},

	abstract = {With the fast development of e-services and the necessity to use information provided by users and their operating environments, Context-Aware Service (CAS) has emerged as a new paradigm of software engineering to dynamically respond to every change in the status of the user{\textquoteright}s context. Context-aware Service can dynamically capture a range of information from its environment and this information represents a context, the application adapts its execution according to this context. An important challenge in ubiquitous computing is context modeling. Ontology based models presents a suitbale instrument for context modeling. In this paper, we provide an architecture for the development of context aware services for an e-learning system, we also present our context metamodel and how the use of ODM (Ontology Definition Metamodel) can be beneficial for ontology modeling.},

	abstract = {In ubiquitous computing, context-aware service oriented systems refer to applications that use so-called contextual information to provide appropriate services or relevant information to the user or other applications to perform a specific task. An important challenge in such applications is context modeling, using ontologies to model context information and to reason about context at a semantic level has attracted a lot of interest in the research community. However, most of the presented approaches do not usually take into account any software engineering method. Therefore, employing standard approaches to formulate the development process becomes of importance. In this paper, we present an overview of the architecture for the development of context aware services based on ontologies, we also present our context modeler based on ODM (Ontology Definition Metamodel) and model transformations that allows to generate an OWL ontology representing context information.},
