With the increasing growth in popularity of Web services, discovery of relevant Web services becomes a significant challenge. One approach is to develop semantic Web services where by the Web services are annotated based on shared ontologies, and use these annotations for semantics-based discovery of relevant Web services. We discuss one such approach that involves adding semantics to WSDL usin...

Semantic Web services provide semantically enhanced service descriptions which allow the development of automated service discovery and composition. Yet, an efficient semantic-based service discovery remains a major open challenge towards a wide acceptance of semantic Web services. In this paper we present a fully-automated matchmaking system for discovering sets of OWL-S Web services capable o...

The process of Web Service Discovery consists of finding the best match amongst a collection of available services to a particular problem or kind of problem. In our particular area of interest, mathematics, this matching process will involve both mathematical ("can it solve my problem?") and non-mathematical ("am I authorised to use it?", "will the resources needed to solve my problem be avail...

Web services technologies promise to create new business applications by composing existing services and to publish these applications as services for further composition. The business logic of applications is described by abstract processes consisting of tasks which specify the required functionality. Web services provision refers to assigning concrete Web services to perform the constituent t...

The automatic location of services that fulfill a given need is seen as a key step towards dynamic and scalable integration. In this paper we present a model for the automatic location of services that considers the static and dynamic aspects of service descriptions and identifies what notions of match and techniques are useful for the matching of both. Our model presents three important featur...

The paper represents current achievements of an ongoing research that aims to develop a formal approach supporting an automatic selection of a Web service sought by a requestor. The approach is based on the matching the requestor’s requirements for a ”useful” service against the service description offered by the provider. We focus on the checking behavioral compatibility between operation cont...

Annotation paths are a new method for semantic annotation which overcomes the limited expressiveness of semantic annotations by concept references as defined in the SAWSDL standard. In this work we show some preliminary evaluation of the feasibility of annotation paths for web service discovery. The experiments suggest that annotation paths can capture the semantics of XML schemas and web servi...

We demonstrate Web Service Execution Environment (WSMX), a semantic middleware platform for runtime service discovery, mediation and execution, applied to SWS-Challenge scenarios. We show the modelling principles as well as execution aspects of the WSMX semantic technology addressing the real-world requirements.

The number of Web services are growing at an explosive speed, which brings great challenges to the accurate, efficient and automatic retrieval of target services for users. This paper presents a service discovery method with semantic matchmaking which could be used in remote medical systems. Adding ontology related semantic annotations to service interfaces is considered, and a method of servic...
