Semantic interoperability of Web services: A survey

Service Oriented Architectures (SOA) and Web services (WS) are important for creating interoperable information systems. However, these technologies lack of semantics. To overcome this limitation, semantic Web services are necessary. In this paper we present a synthesis of some recent works we estimate interesting in the field of semantic interoperability via Web services. We first present some conceptual and technological tools permitting the semantic interoperability. Then, we try to classify the considered works through a comparative table using some criteria concerning the semantic description approach and language, the integration approach, the functions taken into account (publication, discovery, invocation....), the mediation level and the composition method.
