Ontology

Prev | Next | glossary

Fri, Nov 14, 2003; by Geoffrey Wirth. Originaly ontology is a metaphysical term: That department of the science of metaphysics which investigates and explains the nature and essential properties and relations of all beings, as such, or the principles and causes of being.

An ontology is a formal, explicit specification of a shared conceptualization.

  • 'Conceptualization' refers to an abstract model of phenomena in the world by having identified the relevant concepts of those phenomena.
  • 'Explicit' means that the type of concepts used, and the constraints on their use are explicitly defined.
  • 'Formal' refers to the fact that the ontology should be machine readable.
  • 'Shared' reflects that ontology should capture consensual knowledge accepted by the communities.
