The talk will deal with the problem of service discovery in open systems. Different service description languages are considered and integrated into a unified framework, which allows specifying advertisements and queries in any of those languages. Those models include semantic models (OWL-S, WSMO), syntactic (WSDL), hybrid (SAWSDL), as well as other lighter approaches (keyword-, cloud-, and text-based service descriptions). Service descriptions are mapped into a unified common model.We do not only consider explicit information specified in structured service descriptions, but we enrich descriptions with additional information extracted using text processing.Then, we will focus on the service matchmaking process. The proposed method combines classical logic-based semantic service matchmaking approaches with concept similarity measures.
