“... FAO’s principle task is to work
to ensure that the world’s
knowledge of food and
agriculture is available to those
who need it when they need it
and in a form which they can
access and use ...”

..from thesaurus to Ontologies….

 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

 around 30,000 concepts
 600000 labels in around 20 languages.
 one-stop shop for terminological knowledge related to
agriculture in general
 a knowledge base of related concepts organized in
ontological relationships (hierarchical, associative,
equivalence)
 Is a concept/term/string based system
 Concepts may be organized in multiple categories.

Drupal
AgriDrupal is a “suite of solutions” for agricultural information
management and dissemination, built on the Drupal CMS by different
Institutions and individuals who are now sharing their experiences in the
AgriDrupal community
 Drupal, a semantic web enabled CMS
 General purpose CMS necessary
 Drupal has flexibility to manage all information types
 Drupal has a strong user community
 Version 7 natively with RDF backbone, but semantic applications
already possible with version 6
 Drupal can be a producer and consumer of Linked Data

• Objectives:
• Assure quality in metadata creation
• Sharing information in a standardized manner
• Use of common semantics and interoperable
syntaxes
• Use of more sophisticated and specialized
metadata
• Use of controlled, multilingual vocabularies
• Requirements:
• AGRIS AP compliancy
• AGROVOC

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

• 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

Editor's Notes

  • #16 Some auto appreciation
  • #17 Thisis the AGROVOC SKOS modelthathasbeendeveloped and decided in April 2010 under activecollaborationfrom Tom Baker, whowasmemberof the W3C SKOS workinggroup.
  • #29 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
  • #31 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
  • #32 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.
  • #33 The tableshows 3 descriptorsthat are in AGROVOC, EUROVOC and UNBIS. In AGROVOC and EUROVOC they are alreadyencodedasURIs. Easilywecouldestablishrelationshipslikeowl.sameAsbetween the concepts or skos:exactMatchbetweenlabels.
  • #34 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.
  • #35 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
  • #37 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.
