- The Semantic Web needs a support of ontologies:
“defines the concepts and relationships used to describe and represent an area of knowledge”
“defines the concepts and relationships used to describe and
represent an area of knowledge”
- We need a Web Ontologies Language to define:
- the terminology used in a specific context
- more constraints on properties
- the logical characteristics of properties
- the equivalence of terms across ontologies
- etc.
- Language should be a compromise between
- rich semantics for meaningful applications
- feasibility, implementability
