CODATA-VAMAS UDSnano applicability for ontology engineering with suggested changes to improve its structural logic model

  1. 1. CODATA-VAMAS JWG on Description System for Materials on the Nano-scale Uniform Description System (UDS) for Materials on the Nano-scale A Draft Framework COMMENTS - NORWAY ICSU Headquarters Paris, France, 2014-04-14/15 Nordic Quantum Computing Group AS @ 2014 12014-04-14/15
  2. 2. The four UDS information categories  General identifiers  Characterization  Life cycle history  Specifications Nordic Quantum Computing Group AS @ 2014 22014-04-14/15
  3. 3. Thumb rules for ontology construction  An ontology class should not contain too many members  The class structure should be a convenient representation of the domain of knowledge. (User dependent)  These points guides the division of concepts into classes and properties in the ontology Nordic Quantum Computing Group AS @ 2014 32014-04-14/15
  4. 4. Division of UDS categories into ontology classes and properties Nordic Quantum Computing Group AS @ 2014 42014-04-14/15
  5. 5.  Substructure of the UDS ontology classes Nordic Quantum Computing Group AS @ 2014 52014-04-14/15
  6. 6.  Substructure of the UDS property hierarchy Nordic Quantum Computing Group AS @ 2014 62014-04-14/15
  7. 7.  We have added the “Specifications” property three for convenience  The UDS category “General identifiers” is split into ontology classes and data properties; “Common names” and “Material classes” are classes in the ontology while “Specific names” and “Identification numbers and codes” are data properties Nordic Quantum Computing Group AS @ 2014 72014-04-14/15
  8. 8. The “Individual nano-object” class Nordic Quantum Computing Group AS @ 2014 82014-04-14/15
  9. 9. Part of the entire class structure Nordic Quantum Computing Group AS @ 2014 92014-04-14/15

  11. 11. Ontology applied to real nanomaterials Nordic Quantum Computing Group AS @ 2014 112014-04-14/15
  12. 12.  The ontology interface tells us that the class “Single-walled” is a subclass of “Nanotube” and has (currently) one member called “755710 ALDRICH”  To learn more about this individual we click on its name following the diamond in the right panel: Nordic Quantum Computing Group AS @ 2014 122014-04-14/15

  14. 14.  The left panel shows all the ontology classes this nanomaterial belongs to  The right panel gives numerical values of various data properties Nordic Quantum Computing Group AS @ 2014 142014-04-14/15
  15. 15. Conclusion  The four information categories of the UDS system appear to be convenient for construction of ontologies for nanomaterials  Ontology building would however be easier if each UDS category could be implemented as EITHER ontology class OR property. For example, the “General identifiers” category contains both “Classes” and “Specific names”. While “Classes” is (of course) a natural ontology class, a class of “Specific names” would contain all nanomaterials, and thus “Specific names” was implemented as a data property instead.
