  • 12. AAT: Art & Architecture Thesaurus ULAN: Union List of Artists Names TGN: Thesaurus of Geographic Names CONA: Cultural Object Name Authority Getty vocabularies They are all constructed as thesauri
  • 13. CONA: Eiffel tower ID: 700000116 Record Type: Built Work Titles: Eiffel Tower (preferred,C,U,English-P,U,U) Tour Eiffel (C,U,French,U,U) Three-Hundred-Metre Tower (H,U,undetermined,U,U) Work Types: watchtower [300134522] (preferred) (AAT) Creator Display: architect Eiffel, Gustave (French architect and engineer, 1832-1923) [500000800] (ULAN) Locations: Paris [7008038] V (TGN) Display Materials: structural iron [300011010] (AAT) wrought iron (iron alloy) [300011012] (AAT) exposed frame construction [300310589] (AAT)
  • 14. Definition of thesaurus • A semantic network of unique concepts • Thesauri may be monolingual or multilingual • Thesauri may have the following three relationships: • Equivalence Relationships • Hierarchical Relationships • Associative Relationships
  • 15. Why still the need for Controlled vocabs? 1. Synonyms • ‘salinity’ and ‘saltiness’ • ‘VHS’ and ‘Very High Frequency’ 2. Homonyms  Mercury (planet)  Mercury (metal)  Mercury (automobile)  Mercury (mythical being) The purpose is fiveways 1. For translation 2. For consistency 3. For indication of relationships 4. For labeling and browsing 5. For information retrieval
  • 16.  Developed since 1980  36.000 concepts, and 255.000 terms  Generic concepts for describing objects and images  No names of persons and unique events  ‘Cathedal’ yes, but not ‘Chartres cathedral’ (CONA)  Strict editorial control, validation by sources  Thesaurus construction follows ISO standard  Multi-linguality  international scope
  • 17. Structure of the AAT  AAT is organized for general use FAQ: why aren't terms organised like I expect them to be. Why aren’t communion cups and chalices narrower terms to church plate? Communion cups BT: drinking vessels BT: liturgical vessels  The AAT's organization stresses function and form over the context in which an object is used  The AAT links concepts to an alternate parent using polyhierarchical relationships
  • 18. Thesaurus relations The Hierarchical Relationship broader- en narrower terms
  • 19. Thesaurus relations The Equivalence Relationship
  • 20. Thesaurus relations: Associative Relationship Example for "watercolors" paintings Relationship Type: 2212 produced by Related Concept: watercolor brushes (<artists' brushes by function>, artists' brushes, ...
