A Comparative Study on Semantic Web Services Frameworks from the Dynamic Orchestration Perspective.

This paper presents a comparison between the two main existing frameworks for modelling Semantic Web Services, namely OWL-S and WSMO, based on the formal support they provide for reasoning. The adopted yardstick is the set of use cases dictated by one of the foremost tasks in the research field: the dynamic orchestration. As explained in the paper, the term dynamic denotes the capability of an agent to design and manage in an automatic way an orchestration schema using the semantic descriptions of some services. This capability, strictly related to the automatization of Discovery, Selection, Composition and Invocation use cases, is constrained by the knowledge representation strategies adopted by WSMO and OWL-S. As consequence, each approach has some limits discussed in this work.
