Ontology & Ontologies* [2]
• Ontologies are usually expressed in a logic-based language, so that
detailed, accurate, consistent, sound, and meaningful distinctions can
be made among the classes, properties, and relations.
• Ontologies figure prominently in the emerging Semantic Web as a way
of representing the semantics of documents and enabling the semantics
to be used by web applications and intelligent agents.
• Ontologies can prove very useful for a community as a way of
structuring and defining the meaning of the metadata terms that are
currently being collected and standardized.
• Using ontologies, tomorrow's applications can be "intelligent", in the
sense that they can more accurately work at the human conceptual
level.
