  9. 9. dr johannes keizer - FAO of the United Nations - knowledge and capacity for development Chinese Agricultural Ontology Service WS, Beijing 2010-10-30  Our push of AGROVOC to the Semantic Web had enormous positive effects, among others  From 4 to 20 language versions  Defacto standard for indexing in many areas  More than 2000 downloads only in 2009  SKOS incorporated all our requirements  For many purposes we need semantics on a lower level than of a fully elaborated ontology – but we need them urgently  The development of specific Ontologies should be always application driven – a demand economy Lessons Learned

  35. 35. dr johannes keizer - FAO of the United Nations - knowledge and capacity for development Chinese Agricultural Ontology Service WS, Beijing 2010-10-30 What are we doing with unstructured data? • We have enormous amounts of unstructured material • Still most of the documents that we are producing are mostly semantically unstructured • Human work to catalogue and index is becoming always more rare • We need machines to do automatic semantic mark ups of text • If machines are trained and based on concept schemes, ther are able to do so

  37. 37. dr johannes keizer - FAO of the United Nations - knowledge and capacity for development Chinese Agricultural Ontology Service WS, Beijing 2010-10-30 • Does Concept identification in unstructured texts • Uses Agrovoc as a controlled vocabulary • Prototype under testing with excellent results (entire repository of ICARDA indexed) • Will produce in future Structured RDF files that can be used to link data like “open Calais” • AgroTagger
