  13. 13. ..from thesaurus to Ontologies….<br />
  14. 14. <ul><li>We wanted to make a semantic web tool from AGROVOC
  15. 15. There was no standard model outside, we were on our own
  16. 16. We discussed three years the model to which we wanted to convert AGROVOC</li></ul>……but in the meantime AGROVOC was used and translated into 20 languages<br />AGROVOC since 2004<br />
  17. 17. Semantic Relationships<br />
  18. 18. The AGROVOC OWL model<br />
  19. 19. More semantics<br />MAIZE<br /> UF corn <br /> NT flint maize NT popcorn NT sweet corn  <br />MILK<br /> NT Milk Fat <br /> NT Colostrum<br /> NT Cow Milk<br />International Fund for Agricultural Development<br /> UF IFAD <br />MAIZE<br /> synonym corn<br />superclass-of flint maize used-to-make popcorn hybridized-into sweet corn  <br />MILK<br />ingredient Milk Fat <br />ingredientColostrum<br />superclass-of Cow Milk<br />International Fund for Agricultural<br /> Development<br /> acronym IFAD <br />
  20. 20. <ul><li>around 30,000 concepts
  21. 21. 600000 labels in around 20 languages.
  22. 22. one-stop shop for terminological knowledge related to agriculture in general
  23. 23. a knowledge base of related concepts organized in ontological relationships (hierarchical, associative, equivalence)‏
  24. 24. Is a concept/term/string based system
  25. 25. Concepts may be organized in multiple categories.</li></ul>AGROVOC today<br />
  26. 26. <ul><li>The AGROVOC OWL model needs a revision
  27. 27. Ontological over commitment in many class/subclass hierarchies
  28. 28. Unnecessary complications through concept /term/string hierarchy
  29. 29. Our push of AGROVOC to the Semantic Web had enormous positive effects, among others
  30. 30. From 4 to 20 language versions
  31. 31. Defacto standard for indexing in many areas
  32. 32. More than 2000 downloads only in 2009
  33. 33. SKOS incorporated all our requirements</li></ul>Evaluation of the Process<br />

  36. 36. <ul><li>Is a web-based working environment for managing the AGROVOC Concept Server
  37. 37. Facilitate the collaborative editing of multilingual terminology and semantic concept information
  38. 38. It includes administration and group management features
  39. 39. It includes workflows for maintenance, validation and quality assurance of the data pool
  40. 40. The CS is accessible freely to everybody to facilitates collaborative editing </li></ul>The workbench<br />
  41. 41. Architecture of the System<br />
  42. 42. Concept/Term Management<br />
  43. 43. Concept Relationship<br />Can create the concept-concept relationship<br />Inverse relationship is also created automatically<br /><ul><li>Ex: If we create A affect B, then B is affected by A relationship is also created</li></li></ul><li>Concept Image<br />Name of the image with description <br />URL will point to the image which will open in an external<br />Provide the source of the image<br />Can add more translation in different language<br />
  44. 44. Concept Definition<br />Add definition to the selected concept <br />Add translation in different languages<br />Provide the source of the definition<br />Creation and modified date are set automatically<br />
  45. 45. Visualization of concepts and Relationships in the Workbench<br />
  46. 46. AGROVOC Web Services<br />
  47. 47. The road map<br /><ul><li>The AGROVOC concept scheme in it’s proprietary OWL model will be published on June 5, 2010 on version 1.0 of the concept server workbench
  48. 48. Within Summer 2010 a patch to version 1.0 of the workbench will make it possible to export AGROVOC SKOS
  49. 49. AGROVOC SKOS will be published as linked data.
  50. 50. With version 2.0 of the workbench SKOS will become the native format for AGROVOC</li></li></ul><li>…and more<br />
  51. 51. Thank You!<br />
