Current existing semantic composition methods mainly rely on ontology reasoning to support automated service composition. However, in reality, ontologies are generally unavailable or ontology reasoning is time-consuming; thus existing semantic composition methods are becoming impractical in the general service integration field. To address this problem, in this paper, we present an innovative composition...
Web service composition is emerging as a promising technology for supporting large-scale, sophisticated business process integration in a variety of complex e-science or e-business domains. Particularly, semantics have been proposed as a key to automatically solving the discovery and composition problem. However, most of semantic composition approaches still remain at a stage of low efficiency because...
Current service composition and coordination still remain at large amount of manual processing stage, which has brought about low efficiency. In this paper, we present an efficient algorithm for abstract service discovery and a service instance selection method. Our algorithm firstly builds up the special data structures of ontology concepts based on graph storage theories when publishing abstract...
