WAICENT (World Agricultural Information Center) is FAO’s approach to fight hunger with information FAO itself produces huge amount of content in it’s subject area It is also within FAOs mandate to make available useful information from other information providers FAO collaborates in information networks

The Agricultural Ontology Service: A proposal to create a Knowledge Organisation Framework in the Area of Food and Agriculture Johannes Keizer, Food and Agriculture Organization of the UN, Library and Documentation Systems Division Dublin Core Meta Data Initiative Conference, Tokyo, October 2001 Slide 7 Ontologies - Definitions The term “ontology” has been used for a number of years by the artificial intelligence and knowledge representation community but is now becoming part of the standard terminology of a much wider community including information systems modelling and XML An ontology is a vocabulary of terms and relations rich enough to enable us to express knowledge and intention without semantic ambiguity Ontology describes domain knowledge in a generic way and provides an agreed-upon understanding of a domain Ontology is THE key technology in semantic information processing

Domain Ontologies will integrate meta data schemas. This will allow machines to process information and to extract knowledge The definition of the DC Schema correspondends quite well to the definition of an ontology Metadata must be rich and of high quality to improve information retrieval. Ontologies can help to produce them The AOS will deliver tools to define the subject element of the DC element set

The Agricultural Ontology Service: A proposal to create a Knowledge Organisation Framework in the Area of Food and Agriculture Johannes Keizer, Food and Agriculture Organization of the UN, Library and Documentation Systems Division Dublin Core Meta Data Initiative Conference, Tokyo, October 2001 Slide 20 Discussion points  What kind of need do you see for a meta-ontology paralleling what the UMLS has done? For what would you use such a system?  Is it conceivable to run this project as a series of pilot projects with subject domains (e.g., forestry, fisheries, sustainable development, crop wild relatives) – in the end building the complete AOS?  What issues do you see regarding the building of ontological associations?  Who should participate in the project as full partners and who as peripheral partners? What are their respective responsibilities?  Who are the primary and secondary user types for the AOS?  What toolkit will be needed to create and maintain the AOS? What are the components of this toolkit?  What encoding standards should be used (e.g., RDF, DAML+OIL)?
