  10. 10. Caterina Caracciolo, FAO http://www.fao.org/aims/ 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
  11. 11. Caterina Caracciolo, FAO http://www.fao.org/aims/ 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

  13. 13. Caterina Caracciolo, FAO http://www.fao.org/aims/ 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
  14. 14. Caterina Caracciolo, FAO http://www.fao.org/aims/ 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”
