We continue our mini series on upper level ontologies with an episode on the Basic Formal Ontology, or BFO. John Beverley of University at Buffalo joins us. John is the current steward of BFO, and works with its founder Barry Smith on its use in domain applications.

For more information about BFO, visit their github page at https://github.com/BFO-ontology/BFO-2020.

Keith Corbett and Grace Roessling join us for a discussion about learning RDF, OWL, and knowledge graphs.

Keith: For nearly 50 years, Keith has been a technical communicator, data modeler, and knowledge engineer. Then and now, he has explored the intersections of deterministic AI, hypertext, and graph data.

Grace: Grace is a PhD candidate cognitive science at Rensselaer Polytechnic Institute. in the Perception and Action lab with Dr. Brett Fajen. Her dissertation is focused on how humans combine vision and spatial knowledge to guide high speed steering.

In this episode, Deborah McGuinness and I discuss ontologies: what's in them, what they're used for, what makes them good, and how to go about making them.
