  • AGROVOC
    • A multilingual thesaurus
    • Some 20 languages
    • To standardize and organize terminology, primarily for document indexing
    • Coverage: all subject fields in agriculture, forestry, fisheries, food and related domains (e.g. environment)
    • By language: ca 40000 terms EN
  • EXAMPLE Hierarchical and non-hierarchical relationship of the term " Maize "
  • AGROVOC
    • Initiative of FAO and CEE (now EU), 1980s
    • Maintained and updated online by FAO
    • By language: ca 40000 terms EN
    • Localized versions maintained by other bodies: ministries, libraries, research institutes
    • http://aims.fao.org/agrovoc/
  • AGROVOC languages
  • Some figures of AGROVOC use
    • Average hits per day: 5400
    • Average downloads per year: 1000
    • Origin of online access: about 90 countries
    • Who: researchers, librarians, information managers
  • Applications of AGROVOC
    • In library setting: index items with one word (descriptors), retrieve through many (non-descriptors, related or BT/NT terms)
    • AGRIS
    • Multilinguality allows for:
      • coverage of local environment and issues
      • searches across languages
  • Applications of AGROVOC cnt’d
    • For data and web site organization: AgriDrupal
      • inclusion of AGROVOC hierarchies in content management systems
    • Network of users
    • Focal points: CONDESAN, IIT Kanpur
  • Refinement of AGROVOC The Agricultural Ontology Service Concept Server (AOS CS)
  • Refinement of semantics: the Agricultural Ontology Service Concept Server (AOS CS)
    • Based on AGROVOC
    • A pool of agricultural concepts, better defined than in a thesaurus setting
    • Semantics is refined and made explicit, for example the non-hierarchical relations
  • Refined semantics
    • E.g. generic relationship of relatedness is replaced by more refined relations
    • In thesaurus: "pollutants" (RT) "pollution"
    • With refined semantics:
      • “ pollution” (is-caused-by) “pollutants”
  • Refined semantics cnt'd MAIZE UF corn NT flint maize NT popcorn NT sweet corn   MILK NT milk fat NT cow milk RT dairy cattle Fr Lait International Fund for Agricultural Development UF IFAD MAIZE synonym corn superclass-of flint maize used-to-make popcorn hybridized-into sweet corn   MILK ingredient milk fat superclass-of cow milk produced-by dairy cattle has-translation Lait International Fund for Agricultural Development acronym IFAD
