  4. Knowledge Organization • “tools that present the organized interpretation of knowledge structures” (Hjørland) • “classification schemes that organize materials at a general level…, subject headings that provide more detailed access, and authority files that control variant versions of key information” (Hodge)

  5. A good CV. . . • Removes ambiguity • Defines relationships between things • Contextualizes information A+

  6. Case study - MeSH • http://www.nlm.nih.gov/bsd/disted/video/

  7. Thesauri Guides • National Information Standards Organization. (2005). Guidelines for the construction, format, and management of monolingual thesauri. ANSI/NISO Z39.19-2005. Bethesda, MD: NISO Press. • http://www.niso.org/standards/resources/Z39-19-2005.pdf?CFID=5559601&CFTOKEN=31747314 • Aitchison, Jean & Gilchirist, Alan.

  9. When is a CV an Ontology? • “The study of being or existence” • “A conceptualization of a specification” (Gruber) • “An ontology formally defines a common set of terms that are used to describe and represent a domain.” (OWL) • Computational application of “Necessary and Sufficient” definitions

  10. OWL? Web Ontology Language • W3c: “semantic markup language for publishing. . .ontologies on the www” • A built-in language: • Class • subClassOf • disjointWith • Encoded in RDF or XML

  11. OWL in Protege • Classes • Sets that contain individuals – Taxonomic, superclass/subclass • Individuals • Examples of a defined concept • Properties • Binary relationship (hasBase,hasTopping) between individuals • Similar to Slots in Protégé 3.4

  12. DC as OWL • Classes: DC Document Model • Object properties: relationships • Data properties: DC elements • Individuals: Actual DC records

  13. Assignment 3 - Ontologies Group or individual Focused on skill development Complete tutorial: Ch 1-6 (P1-88) Reflective statement – Migration of LCSH into OWL form
