Ontologies
- 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”
- Think of well known in traditional “ontologies”:
- use the term “mammal”
- “every dolphin is a mammal”
- “Flipper is a dolphin”
- etc.
- We need a Web Ontologies Language to define:
- the terminology used in a specific context
- possible constraints on properties
- the logical characteristics of properties
- the equivalence of terms across ontologies
- etc.
