P2P support for OWL-S discovery

The discovery of Web services is often in uenced by the rigid structure of registries containing their XML description. In recent years some methods that replace the traditional UDDI registry with Peer To Peer networks for the creation of catalogs of Web services have been proposed in order to make this structure exible and usable. This paper proposes a dierent view by placing the semantic description of services as content of P2P networks and showing that all the needed information for an ecient Web service discovery is already contained in its OWL-S description.
