Service interface description languages such as WSDL, and related standards, are evolving rapidly to provide a foundation for interoperation between Web services. At the same time, Semantic Web service technologies, such as the Ontology Web Language for Services (OWL-S), are developing the means by which services can be given richer semantic specifications.(More)
Current industry standards for describing Web Services focus on ensuring interoperability across diverse platforms, but do not provide a good foundation for automating the use of Web Services. Representational techniques being developed for the Semantic Web can be used to augment these standards. The resulting Web Service specifications enable the(More)
In this paper, we introduce a vision for Semantic Web services which combines the growing Web services architecture and the Semantic Web and we will propose DAML-S as a prototypical example of an ontology for describing Semantic Web services. Furthermore, we show that DAML-S is not just an abstract description, but it can be efficiently implemented to(More)
Web services will soon handle users' private information. They'll need to provide privacy guarantees to prevent this delicate information from ending up in the wrong hands. More generally, Web services will need to reason about their users' policies that specify who can access private information and under what conditions. These requirements are even more(More)
The increasing availability of web services demands for a discovery mechanism to find services that satisfy our requirement. UDDI provides a web wide registry of web services, but its lack of an explicit capability representation and its syntax based search provided produces results that are coarse in nature. We propose to base the discovery mechanism on(More)
The relation between DAML-S, a language for the description of Web services grounded in the Semantic Web, and the growing Web services infrastructure based on WSDL is, by an large, still an open question. In this paper we describe a mapping from WSDL to DAML-S whose contribution is twofold: on the theoretical side it clearly shows what information is(More)

Mechanisms for Web services Discovery proposed so far have assumed a centralized registry that collects information about all the Web services available at any given time. Centralized registries are performance bottlenecks and may result in single points of failure. In this paper, we propose an alternative architecture based on a P2P connection between Web(More)
The increasing availability of web services necessitates efficient discovery and execution framework. The use of xml at various levels of web services standards poses challenges to the above process. OWL-S is a service ontology and language, whose semantics are based on OWL. The semantics provided by OWL support greater automation of service selection,(More)
