Semantic Web Services Composition in the astrophysics domain: Issues and solutions

Semantic Web services (SWS) have been hailed for their role in realizing the potential of composing services in the context of service-oriented computing. However, many application domains, such as astrophysics, require a major rethinking of how service composition should take place despite his potential. In this paper, we describe an approach for automatic, user-friendly SWS composition for the astrophysics domain that features certain particularities like correlated or optional inputs, aggregates, and inclusion of non-Web services. The approach selects the best SWSs using non-functional requirements along with users' previous experience feedback and is demonstrated using some real astrophysics services.
