Ontology Combined Structural and Operational Semantics for Resource-Oriented Service Composition

Resource-oriented services recently become an enabling technology to integrate and configure information from different heterogeneous systems so as to meet ever-changing environment which not only need the concepts for entities but also require the semantics for operations. by the aim of combining structural and operational semantics agilely, a semantic resource service model (srsm) is proposed. firstly, srsm describes entity-oriented and transition-oriented resource by semantic meta-model which contains data structures and operation semantics. secondly, by describing structural semantics for entity-oriented resource, heterogonous inputs/outputs of a service can be automatically matched. thirdly, by describing operational semantics for transition-oriented resource, the service composition sequence can be inferred after ontology reasoning. then, both entity-oriented and transition-oriented resources are encapsulated into composited restful service. at last, a case study and several comparisons are applied in a prototype system. the result shows that the proposed approach provides a flexible way for resource-oriented service composition.
