From Data Models to Ontologies: A Tutorial

David Hay David Hay

Tuesday 2:15pm - 3:15pm

Level: Data Management - Intermediate

The world of data modeling and database design has developed over nearly 40 years within the information technology industry. The world of semantics and ontologies has developed over about 2500 years within the worlds of philosophy, linguistics, and more recently, artificial intelligence. The time has finally come to bring these worlds together. This presentation is an attempt to take the first steps towards doing that.

The presentation will describe data modeling in its various forms and use an example to show the relationships between its concepts and those of the ontology language OWL. Covered will be the relationships between entity classes and OWL classes, attributes and datatype properties, and relationships and object properties. This will include a discussion of taxonomies and alternative classification approaches.

The presentation will focus on both the similarities and the fundamental differences between the two approaches.
