jUDDI+: A SemanticWeb Services Registry enabling Semantic Discovery and Composition

摘要

We propose an extended version of a UDDI registry for semantic-based automated Web service discovery and composition, compliant with Semantic Web technologies. The approach exploits non-standard inference services in a fragment of OWL DL to perform semantic matchmaking and covering. The proposed approach also deals with effect duplication and non-exact solutions, computing an approximate composition and providing an explanation of which part of the request is not covered by the composite web service.
