  1. Agricultural Ontology Web Services Striving for more interoperability in agricultural information management Boris Lauser Food and Agriculture Organization of the United Nations (FAO), Rome, Italy OASIS Symposium 2006 9 May 2006

  2. Overview • FAO and its role • Introduction to AGROVOC thesaurus • Present situation and problems • AGROVOC web services • AOS and AOS Concept Server • Outlook: AOS/CS web services AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  3. The role of the Food and Agriculture Organization (FAO) The First Article of the FAO Constitution: • “The Organization shall collect, analyse, interpret and disseminate information relating to nutrition, food and agriculture.” WAICENT: World Agricultural Information Centre • Knowledge Management • Information Dissemination • Collaboration with internal/external stakeholders • Promotion of Agricultural Information Management Standards (AIMS)(bibliographical databases, use of metadata and knowledge organization systems (KOS) like thesauri, ontologies, etc.) AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  4. What is AGROVOC? • Multilingual Thesaurus; • Structured vocabulary to cover terminology in agriculture, fisheries, forestry, food and related domains; • Currently available in 14 languages; • about 30.000 terms • Available online at http://www.fao.org/aims/ag_alpha.htm. AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  5. Use of AGROVOC: Metadata from controlled vocabularies AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  6. Present Situation WebAGRIS input system local copy AGRIS center Thailand local copy x local copy y local copy AGRIS center Venezuela AGROVOC thesaurus relational database master copy local copy AGRIS center Ukraine ..... local copy z local thesaurus browser z AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  7. Problem local copy AGRIS center Vietnam request toadd new term “Avian Flu” Outdated! local copy AGRIS center Y new term and relationshipsadded local copy AGRIS center Z need to create an updated export and resubmit the physical database to each AGROVOC user AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  8. Summary of Problems • Local databases are frequently outdated (AGROVOC updated 3-monthly); • Overhead for FAO to export and send new copies with every update / new request; • Local applications need to be customized to AGROVOC’s specific database structure; • A new interface needs to be implemented on the local application level for each other thesaurus to be used. AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  9. The solution: web services AGROVOC web services interface SOAP WSDL local application x ..... java web services interface SOAP WSDL AGROVOC web services interface local application y update 1 ... update x AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  10. AGROVOC web service Web service with 6 simple operations: • getTermcodeByTerm • getTermByLanguage • getAllLabelsByTermcode • searchByTerm • getConceptByTerm • getDefinitions sufficient for the most important thesaurus information http://www.fao.org/aims/ag_webservices.jsp AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  11. AGROVOC web services Eclipse Web Tools Platform implementation using standard technologies Apache Tomcat • SOAP • WSDL AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  12. Agricultural Ontology Service (AOS) • Elevate terminology services to the semantic web; • Transform AGROVOC thesaurus to AOS Concept Server; • Move from proprietary relational databases to standard formats. OWLWeb Ontology Language AGROVOC thesaurus Present Situation AGROVOC web services AOS Agricultural ontology web services

  13. Agricultural Ontology Web Services Outlook on possible future web services: • Retrieval of standard OWL representation of terminology; • Retrieval of semantically richer concepts; • Retrieval of semantically richer relationships; • Retrieval of more lexical information (synonyms, acronyms, spelling variants...); • Automatic translation services; • Automatic text classification services; • Mapping services to other standard terminology systems.
