The vision of the Semantic Web aims at enhancing today’s Web in order to provide a more efficient and reliable environment for both providers and consumers
of Web resources (i.e. information and services). To deploy the Semantic Web,
various technologies have been developed, such as machine understandable description languages, language parsers, goal matchers, and resource composition
algorithms. Since the Semantic Web is just emerging, each technology tends to
make assumptions about different aspects of the Semantic Web’s architecture
and use, such as the kind of applications that will be deployed, the resource
descriptions, the consumers’ and providers’ requirements, and the existence and
capabilities of other technologies
