Building a rich ontology from AGROVOC: Why and How

Presentation at FAO Agricultural Ontology Server Workshop Beijing, April 27-29, 2004


This presentation will start with a few examples to illustrate the usefulness of ontologies; it will then develop a set of concept relationships to be included in an ontology, based on an in-depth analysis of the BT/NT and RT relationships in AGROVOC, determining what they really mean. Lastly, it will present the "rules-as-you-go" approach to an efficient transformation of AGROVOC relationships into a more differentiated set of concept relationships. This approach relies on the ontology editor to discover - from the transformation of example concept pairs - rules that allow for the automatic conversion of other concept pairs exhibiting the same pattern, thus drastically reducing the ontology
development effort.
