Expressiveness of Automatic Semantic Web Service Composition Approaches: A Survey based on Workflow Patterns

Abstract

This survey evaluates a number of techniques for the automatic composition of Semantic Web Services. The evaluation takes into account the different workflow patterns that can be expressed by the solutions proposed by each individual technique. Only fully automatic approaches are considered here, i.e., composition techniques that do not demand user interference in the composition process nor rely on complex input (such as templates or other forms of abstract composition models). The main contribution of this paper is to discuss the strengths and weaknesses of the approaches presented in the literature for the automatic generation of semantic web services composition from the workflow patterns perspective.
