Ontologies and semantics
Semantic Web vision : a shared understanding of the meaning of descriptions of digital content (human, m2m)
An ontology defines the terms used to describe and represent an area of knowledge
- classes of “things”
- relationships between things
- properties (attributes) of things
Semantic Web and Web Services are complementary
- WWW and Web Services based on XML
- Semantic Web based on ontology languages e.g. RDF, DAML+OIL
New Web ontology languages under development e.g. DAML-Services, Ontology Web Language (OWL)
