A reflective framework for dynamic evolution of semantic web service composition

Web services are widely applied in web applications. In order to achieve the goals of automation and inter-operation, the idea of semantic web service was introduced, and OWL-S is proposed as the description language of semantic web services. As the requirement of the customer changes frequently, the composition of semantic web service should be correspondently modified. However, modifying the composition of web services is not very convenient in traditional methods (e.g. the user has to shut down the program first, reassemble web services, recompile the program and redeploy it). Based on reflection, this paper proposed a framework that supports the dynamic evolution of semantic web service composition. With the interface provided by this framework, the user can modify the composition of semantic web services at running time. And this framework could be integrated into other projects to implement the dynamic evolution of objects.
