  3. 7th AOS Introduction Brief Introduction on the Mapping Project AGROVOC FAO CAT CAAS ExactMatch InexactMatch BroadMatch NarrowMatch AND,OR,NOT No mapping mapping mapping Resource Mapping Rules Target

  4. 7th AOS Objective Objective 1: Enrich AOS Terminology Domain Knowledge • Key words have problems in search information; • Thesauri are still working in information management; • Research on conversion from thesaurus to ontology; • Mapping can add more new domain knowledge.

  5. 7th AOS Objective CAT Search end Chinese users Chinese data Search Mapping Information ( e, b,n… ) AGRIS data English Users Search AGROVOC Search end Objective 2: Develop Cross-Language Search System

  6. 7th AOS Organizing The Time and Tools of Mapping Project • The time of mapping project: From September 2005 to September 2006; • Mapping rules: a revision method of SKOS Mapping Vocabulary Specification; • Mapping direction: from CAT (resource) to AGROVOC (target) • Mapping tools: Protégé , Excel sheet, CAT and AGROVOC CD-ROM.

  7. 7th AOS Organizing Working Flow • From 2005-09-01 to 2005-11-05: make plans of mapping methods, prepare and test the mapping data; • From 2005-11-06 to 2006-05-30: the training and mapping with Excel sheet; • From 2006-06-01 to 2006-09-30: convert the Excel sheet information to OWL mapping data, Protégé can read this information.

  8. 7th AOS Organizing The specialists • we organized about 16 agricultural domain specialists in CAAS, many of them are PhD students, they were chosen based on the domain. • The main domain are biological science, agricultural environmental science, agricultural meteorology, fertilizer science, horticulture, forestry practice, plant protection, agronomy, agricultural products processing and storage and comprehensive utilization, veterinary medicine, biological control, Industrial technology and equipment, fishery science, and so on. • Some of them have knowledge of thesaurus.

  9. 7th AOS Organizing AGROVOC and CAT • AGROVOC: • 27736 English terms: 16769 descriptors, 10967 non descriptors • 25060 Chinese terms: 16628 descriptors, 8432 non descriptors • 1240 top terms • organized in 130 categories (AGRIS/CARIS) • includes biological taxonomy and geographical names • CAT: • 64638 Chinese terms: 51614 descriptors, 13024 non-descriptors • 51400descriptors has at least one translation • 2332 top terms • organized in 40 categories (e.g. crops, etc.) • includes biological taxonomy and geographical names

  10. 7th AOS Organizing To Finish the Mapping Work in Two Steps • First, Excel sheet: We split CAT into 36 documents based on the domain,we use Excel sheet, try to find all mapping information and input it in the Excel sheet, all these sheets will be kept as original data; • Second,convert information to OWL document: After we finish the all Excel sheets, we convert and input these mapping information into OWL documents, they can be read in Protégé after import CAT and AGROVOC.

  12. 7th AOS Methods Mapping Standards and Methods • Exact Match,Inexact Match； • Broad Match,Narrow Match； • AND；OR；NOT；

  13. 7th AOS Methods Mapping relationships • Exact match • SKOS: exactMatch • OWL: equivalentTo • Broader/Narrower match • SKOS: broadMatch, narrowMatch • OWL: subClassOf • OR, AND, NOT operators • SKOS: OR, AND, NOT • OWL unionOf, intersectionOf, complementOf • Partial equivalences • SKOS: minorMatch, majorMatch

  14. 7th AOS Methods Exact Match Mapping AGROVOC Exact Match CAT Such as：‘17147-禾谷类作物’ Exact Match ‘25512-Cereal crops’

  15. 7th AOS Methods equivalentClass: One of main mapping relation (13105) <rdf:Description rdf:about="http://www.caas.net.cn/2005/cat#c_17147_禾谷类作物_Cerealcrop"> <owl:equivalentClass> <rdf:Description rdf:about="http://www.fao.org/aos/agrovoc/2005#c_25512_Cerealcrops_禾谷类作物"> <owl:equivalentClass rdf:resource="http://www.caas.net.cn/2005/cat#c_17147_禾谷类作物_Cerealcrop"/> </rdf:Description> </owl:equivalentClass> </rdf:Description>

  16. 7th AOS Methods Inexact Match Mapping CAT AGROVOC Inexact Such as：‘经济大国’Inexact match‘Developed countries’

  17. 7th AOS Methods Inexact Match : We seldom use this mapping relation 55581_玉米芯_Maizecobie 16171 <rdf:Description rdf:about="http://www.caas.net.cn/2005/cat#c_55581_玉米芯_Maizecob"> <rdfs:comment rdf:datatype="http://www.w3.org/2001/XMLSchema#string" >inexact mapping with 16171</rdfs:comment> </rdf:Description>
