  • Some auto appreciation
  • Thisis the AGROVOC SKOS modelthathasbeendeveloped and decided in April 2010 under activecollaborationfrom Tom Baker, whowasmemberof the W3C SKOS workinggroup.
  • AgriOceanDspace release: 09/2010Setting up of AgriOceanDspace Community on AIMS: 09-10/2010exchange of experiencesPilot Testing: “Bangladesh Agricultural Universities’ Institutional Repository”Cooperation with DURASPACEInforming about the new AgriOceanDspace implementationsCollaborating in the Dspace Ambassadors Program
  • Thisis a snapshotoneyearlater. The growthisenormous. A centralpointisDBPedia, “triplified” information fromWikipedia. The differentcoloursrepresent the different information types, being “life sciences” and “publications” the mostpopulatedareas, butwith the area “government” stronglygrowingInterestingnewcomers in the last months are the two VIVO datasetsfrom the UnitedStatesdescriping expertise in Science. Vivo isactually a project thatstarted the agriculturallibraryofCornellUniversity
  • In a bibliographical record thereismuch more hidden information thandisplayedwith the metadata. Manyof the highlystructured data are linkingtoother information on the web. In AGRIS wehavenowintroducedsomethingwhatwecall “naivelinking”. An AGRIS record linksautomaticallyto Google Mapsfor the location of the center and to Google toretrieve the full text of the resource, citationlists or otherpublicationsfrom the authors. Thisoftenworks, butclearlynotalway, s asitisnotcontrolledbysemantics, butonlythroughidentyofstrings. Foranuneducatedmachineunfortunately COW and C.O.W. are the same, whereaspeanuts and groundnuts are somethingdifferent.
  • The tableshows 3 descriptorsthat are in AGROVOC, EUROVOC and UNBIS. In AGROVOC and EUROVOC they are alreadyencodedasURIs. Easilywecouldestablishrelationshipslikeowl.sameAsbetween the concepts or skos:exactMatchbetweenlabels.
  • Ifresources are marked up withsemanticallydefined and machinereadableconcepts, they can belinked and mashed up preciselyaswehaveseen in the examplefrom the BBC.In thisexamplewe start withan AGRIS record on Hazardouswaste, whichisindexedwith AGROVOC. Alreadynowwe can easily link to material indexedwithEurovoc, hereanexamplefromEuroLex. If the UNBIS thesaurus wouldberestructuredto a conceptscheme and publishedas LOD, related UN documentscouldbeattachedautomaticallyby the machine.
  • How does this work: A resource is connected with each concept URI in the web. The concepts between three vocabularies are having same literal which is connected with owl:sameAS/exactMatch relationship. As we are speakingaboutthesauri and notontologieswekept the relation tobechosenpurposelyvague. The conceptscouldbematchedwithowl:sameAS or the termscouldbematcheswith SKOS:exactMatch. A lotofdiscussion on thisisongoing
  • Oneof the groundbreakingenterprises in this area isThomsonReuters “Open Calais”. Thisis a webservicethatprovidessemanticmark up foranyunstructured text thatyoufeedintotheir service The service is free ofCharge. Why? I will show youlater.
  • My team in collaborationwith the IndianInstituteofTechnology in Kanpur isdeveloping a similar service foroursubject area.
  • Wehavehere a text from 1964 without a bibliographic record at handabout a plantprotectionissue
  • Open Calais isverygood in thoseareas, in whichtheyhavetheirownelaboratedconceptschemeagainstwhich the texts are analyzed: “Places”, “Persons”, “Business Processes” , “IndustryTerms”, butitisweak in the specifictopicanalysis, whattheycall “social tags”
  • AgroTaggerstilllacksmanyof the sophisticated featuresof “Open Calais” ,butismuch, muchbetter in the subjectanalysisof the text

    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
