	abstract = {The current service discovery mechanisms are syntactic methods that often offer poor quality results. By researching this area we are able to identify issues that limit the quality of the result with these traditional service mechanisms. To overcome this issue we use ontologies to enable semantic matchmaking. By reasoning on concepts and relations, our approach can derive matches that syntactically would not match. Additionaly, by introducing contextual information in the service discovery process, the quality of the service discovery result may improve. In this paper, we present an overview of the architecture for the discovery of context aware services by using ontologies, we also present our context aware semantic service by extending OWL-S with context properties. {\textcopyright} 2015 IEEE.},

	abstract = {The context-aware services refers 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 context-aware service oriented systems is the creation of a new service on demand to carry out more complex tasks through the composition of existing services. In this work, we aim to propose a semantic based architecture for the development of context aware services composition using Artificial Intelligence (AI) planning. The straightforward translation between AI planning through PDDL and Semantic web services via OWL-S allows to automate the composition process. Thus planning based service composition launches a goal-oriented composition procedure to generate a plan of composite service corresponding to the user request.

	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 highlevel 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. {\textcopyright} 2013 IEEE.},

	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. {\textcopyright} 2013 IEEE.},
