The New Zealand Institute for Plant & Food Research Limited Matthew Laurenson Ontologies

The New Zealand Institute for Plant & Food Research Limited Ontologies – the problem Existing Web/database searches based on pattern matching or associations eg a search for “earthquakes Canterbury” wouldn't find “Christchurch rocked by aftershocks”

The New Zealand Institute for Plant & Food Research Limited Solutions Restricted list of keywords - controlled vocabulary »Labour intensive “Is a type of” keyword hierarchy – thesaurus »Broader term »Narrower term »Synonym »Related term Broader range of relationships – ontology »Distinction between classes and individuals »Attributes/relationships »Reasoning

The New Zealand Institute for Plant & Food Research Limited Demo of Protégé-OWL Web Ontology Language (OWL) Protégé-OWL (editor with reasoners)

The New Zealand Institute for Plant & Food Research Limited Keywords Recommend Web Ontology Language (OWL) Protégé-OWL (editor with reasoners) But should mention Semantic Web (Berners Lee et al, 2001) Resource Description Framework (RDF)
