In this paper we present a novel approach and a system for automated selection of building blocks, by exploiting business processes semantics. The selection process is based on a novel greedy concept covering algorithm, which computes, given a description of the request, the set of needed building blocks. If such a set does not exist the algorithm returns the covered subset and explanation information...
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...
