Abstract:
Web services adoption is a major advance in the development of interoperable information systems. In particular, the composition of services can meet the needs increasingly complex of user, by a combination of web services within a single business process. However, despite this widespread adoption of Web services, many obstacles prevent their reconciliation in the composition, or may occur within a BPEL process in a state change, the context for example. ASWSCC Method (Adaptation of Semantic Web Service Composition to Context) is an implementation of a theoretical model made in our an earlier work. It focuses on composition process adaptation to use context (preferences, user type and its environment as the device used, location, access mode and many others). This context and request service matching should be taken into account while composing new services. Our goal is to develop a model which ensures, on the one hand, web services matching during composition process by using domain ontology as lexical database WordNet, its purpose is to identify, classify and relate in different ways semantic content and lexical language. On the other hand, this model allows management and taking into account the context that makes composition process adaptable to different instances of use context, which may change during the same session. For this reason, we are interested to capture and manage the context and its impact on basic services and composition process at once. Changes can affect the context of web services during their executions and the need to adapt their dynamically becomes increasingly crucial. From here comes the need for a coherent solution to adapt web services context. We exploit the benefits of aspect weaving tool in this approach to inject aspects of web services to adapt them to change of context.
