Whatis a Referenceontology?
Nicolas Guarinouses the term : Referenceontology for the first timeduring the 26th GermanConference on Artificial Intelligence (September 15th-18th2003 held in Hamburg)
SinceThen, there have been ManyReferenceontologydefinitionsproposedwhichhighlitedits main features, such as:
To Describe a certain domainadequately

Tobetrue about a certain portion of reality

To beindependentfromspecific objectives

To bevalidated by a large community of domain experts

Whatis a Referenceontology?
Domain Reference ontologies representknowledge about a particular part of the world in a waythatisindependentfromspecific objectives, through a theory of a domain

Whatis a Referenceontology?
Reference ontology
Foundational ontology

  • Declare a theory about a particulardomain of reality

8. Make use of methods of top-level ontologies 9. Generalize to otherdomains (more specificdomains) 10. Domain-independenttheories 11. High degree of representationalaccuracy 12. Designed to be used ascontrols on other ontologies types

Reference ontology

  • Narrow and Shallow:

16. Provides a minimal terminological structure 17. Fits the needs of a specificcommunity

  • Offersterminological services for semanticaccess, checkingconstraintsbetweenterms

18. Lightweight ontologies, designedaccording to the viewpoint of an end-user in a particulardomain 19. Can bederivedfromReferenceontology 20. Broad and Deep: 21. maximal coverage 22. Fits the needs of a largecommunity

  • Establishes consensus about meaning of terms

23. Rich, axiomatictheories, designedaccording to strict ontologicalprinciples 24. Can bederivedfromFoundationalontology
