The Semantic Web realization depends on the availability of a critical mass of metadata for
the web content, associated with the respective formal knowledge about the world. We claim …

Researchers in the ontology-design field have developed the content for ontologies in many
domain areas. This distributed nature of ontology development has led to a large number of …

We describe a policy language designed for pervasive computing applications that is based
on deontic concepts and grounded in a semantic language. The pervasive computing …

As web services become more prevalent, tools will be needed to help users find, filter and
integrate these services. Composing existing services to obtain new functionality will prove …

The paper proposes a novel distributed service discovery protocol for pervasive
environments. The protocol is based on the concepts of peer-to-peer caching of service …

This paper introduces a visual, UML-based notation for OWL ontologies. We provide a
standard MOF2 compliant metamodel which captures the language primitives offered by …

To demonstrate the utility of semantic Web service descriptions for service composition,
we've developed a goal-oriented, interactive composition approach that uses matchmaking …

One of the original motivations behind ontology research was the belief that ontologies can
help with reuse in knowledge representation. However, many of the ontologies that are …

Abstract The Semantic Web realization depends on the availability of critical mass of
