  • Note: we identified outlinks to RAMAEU and GEMET, and they have taken them as inlinks to their own thesaurus.

  • 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”

    • 1. AGROVOC Linked Open Data and the VocBench, potentials for the community
      Dr. Johannes Keizer
      Office ofKnowledge Exchange, Research and Extension
      Food andAgricultureOrganizationofthe UN
      Talk atthe US National Agricultural Library,
      May 20 2011
    • 2. We will promote research for food and agriculture, including research to adapt to, and mitigate climate change, and access to research results and technologies at national, regional and international levels.
      We will reinvigorate national research systems and will share information and best practices.
      We will improve access to knowledge.

    • 3. …Sharing Information
      1975 – AGRIS
      1980 - AGROVOC
      2000 - Rethinking of AGRIS

      What’s new with AGROVOC
      AGROVOC Linked Open Data
      The VocBench
      Why mapping Vocabularies
      Automatic Indexing
      AGRIS
    • 6. AGROVOC
    • 7. AGROVOC
      A multilingual agricultural vocabulary organized as concept scheme in 20 languages
      Covers agriculture, forestry, fisheries and related themes (food security, land use, environment, etc.)
      Organized in sub-vocabularies, e.g. chemicals, fisheries terms, scientific/common names of organisms
      Maintained by a global community (e.g. librarians, terminologists, information managers) using VocBench
    • 8. AGROVOC - Statistics
    • 9. AGROVOC - Restructuring
      Goal: Transform AGROVOC from a traditional thesaurus into a concept scheme with distinction between conceptual level and terminological level
      Overall revision done by FAO in collaboration with KSI (Knowledge Sharing and Innovation) team at ICRISAT, Hyderabad, India
      Top concepts reduced from 918 to 25
      Around 85,000 term relations revised
      Non-hierarchical relationships refined by semantic relations
      Ca. 4,000 non-preferred terms changed to preferred terms

    • 20.
    • 21. Get the NALT into the LOD cloud too!
      Some notes from Ahsan
      Issues
      1.  Only  problem is that  the online version  and  the SKOS version 2011 of NALT are  totally different according to the terms code .  They need to make the stable version of their terms code .2. Since  the AGROVOC is connected with the  NALT so they are in the LOD according to the principle. They can put our 13,000 mapping links into their SKOS file. It will cover outlinks and inlinks.
      Necessary activities
      1. Put the SKOS version in the triple store.2. Make the dereferenceable URIs in their website (They can use the biotech drupal module that we are going to build now)3. Publish the URIs  by using Pubby  tool      http://www4.wiwiss.fu-berlin.de/pubby/

    • 25. VocBench Features
      • Domain independent
      • 26. Structure independent (i.e. thesauri, Glossaries, etc)
      • 27. Supports RDF (SKOS, SKOS-XL), OWL
      • 28. Supports collaborative editing
      • 29. Supports editorial workflow, with user roles
      • 30. Simple and advanced search
      • 31. Supports data export: SKOS, Relational format (MySQL)
    • 32. Why linking vocabularies?

    • 39. If all institutions, which publish about toxic wastes would:
      • - Index their publications with URIs from AGROVOC,GEMET, NALT, LCSH or EUROVOC
      • 40. (many do – low hanging fruit!)
      • 41. - Publish their metadata as LOD
      • 42. (quite easy to do, bibData map well to RDF
      Then
      Everyone who knows to write SparqlQeries could get all these publications with one shot for a new website on toxic wastes
    • 43. Vocabularies and LOD
      Simply publishing your data as RDF does not link them to other data sets 
      Creating this links by humans is interesting in detail, but unrealistic as mass processing
      Linking 2 standard vocabularies can link 200 datasets which use these standard vocabularies
