Presentation by Johannes Keizer (FAO) at the IAALD 2010 World Congress - 26-29 April 2010, Montpellier, France

1. The AGROVOC Concept Server Workbench System: Empowering management of agricultural vocabularies with semantics Margherita SINI1, Sachit RAJBHANDARI1, Maziar AMIRHOSSEINI2, Gudrun JOHANNSEN1,Ahsan MORSHED1, Johannes KEIZER1, 1FAO of the UN, Italy; 2The faculty of Information Science and Technology, UniversitiKebangsaan, Malaysia

2. Do we need AGROVOC? Yes!And Why:

3. The Linked Data Universe: http://www.linkeddata.com 3

5. Finding things related to “genes” across databases Source: Joanne Luciano, Mitre, and the W3C HCLS IG

7. Using Agrovoc as a controlled vocabulary

8. Structured RDF files that can be used to link data

9. Developed by IIT Kanpur for AgroPediaIndica

10. Prototype under testing with excellent resultsAgroTagger

11. http://agropedia.iitk.ac.in/auto_tagger/callable_auto_tagger.php

12. AGROVOC: From a traditional thesaurus to an Agricultural Concept Scheme A long and Winding Road

13. ..from thesaurus to Ontologies….

15. There was no standard model outside, we were on our own

16. We discussed three years the model to which we wanted to convert AGROVOC……but in the meantime AGROVOC was used and translated into 20 languages AGROVOC since 2004

17. Semantic Relationships

18. The AGROVOC OWL model

19. More semantics MAIZE UF corn NT flint maize NT popcorn NT sweet corn MILK NT Milk Fat NT Colostrum NT Cow Milk International Fund for Agricultural Development UF IFAD MAIZE synonym corn superclass-of flint maize used-to-make popcorn hybridized-into sweet corn MILK ingredient Milk Fat ingredientColostrum superclass-of Cow Milk International Fund for Agricultural Development acronym IFAD

21. 600000 labels in around 20 languages.

22. one-stop shop for terminological knowledge related to agriculture in general

23. a knowledge base of related concepts organized in ontological relationships (hierarchical, associative, equivalence)‏

24. Is a concept/term/string based system

25. Concepts may be organized in multiple categories.AGROVOC today

27. Ontological over commitment in many class/subclass hierarchies

28. Unnecessary complications through concept /term/string hierarchy

29. Our push of AGROVOC to the Semantic Web had enormous positive effects, among others

30. From 4 to 20 language versions

31. Defacto standard for indexing in many areas

32. More than 2000 downloads only in 2009

33. SKOS incorporated all our requirementsEvaluation of the Process

37. Facilitate the collaborative editing of multilingual terminology and semantic concept information

38. It includes administration and group management features

39. It includes workflows for maintenance, validation and quality assurance of the data pool

40. The CS is accessible freely to everybody to facilitates collaborative editing The workbench

41. Architecture of the System

42. Concept/Term Management

44. Concept Definition Add definition to the selected concept Add translation in different languages Provide the source of the definition Creation and modified date are set automatically

45. Visualization of concepts and Relationships in the Workbench

46. AGROVOC Web Services

48. Within Summer 2010 a patch to version 1.0 of the workbench will make it possible to export AGROVOC SKOS

49. AGROVOC SKOS will be published as linked data.

51. Thank You!
