Ontology-based service discovery in p2p networks
 by Daniel Elenius & Magnus Ingmarsson.

The ubiquitous computing vision is to make knowledge and services easily available in our everyday environments. A wide range of devices, applications and services can be interconnected to provide intelligent and automatic systems that make our lives more enjoyable and our workplaces more efficient. Interaction typically is to be between peers rather than clients and servers. In this context, the JXTA peer-to-peer infrastructure, designed for interoperability, platform independence and ubiquity, is a suitable foundation to build future computer systems on. Peers need ways to effortlessly discover, consume and provide services, and to take advantage of new services as they become available in a dynamically changing network. However, JXTA does not currently handle this service-discovery problem. In this paper, we examine several service-discovery architectures, to see whether they can be adapted to JXTA. We conclude that none of them adequately support the flexibility and expressiveness that ubiquitous computing requires. We therefore argue that Web Ontology Language (OWL) and OWL Services (OWL-S) ontologies should be used to express detailed semantic information about services, devices and other service-discovery concepts. This kind of approach allows peers to reason about service offerings and achieve intelligent service discovery by using an inference engine. We present an experimental implementation of this ontological approach to service-discovery, called Oden (Ontology-based Discovery-Enabled Network)
