With Ora Lasilla and Adrian Gschwend

We discuss reification using the W3C draf recommendation RDF 1.2, modeling choices, and how the approach is similar to, and different from, edge properties in Labeled Property Graphs.

What's in a Triple?

With the entire knowledge graph community!

This week I was at the Knowledge Graph Conference, the biggest industry Graph AI conference out there! I spoke with Bob Metcalfe of network effect fame, Peter Crocker of Oxford Semantics, and a huge KGC crew of ontologists, technologists, and knowledge graph experts. Featuring:<ol><li>Bob Metcalfe</li><li>Peter Crocker</li><li>Mara Inglezakis Owens</li><li>Margaret Warren</li><li>Pete Rivett</li><li>Hande McGinty</li><li>Tom Plasterer</li><li>Ora Lassila</li><li>Keith Corbett</li><li>Elisa Kendall</li><li>Larry Swanson</li><li>Deborah McGuinness</li></ol>

KGC-palooza!

With John Beverley

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 <a href="https://github.com/BFO-ontology/BFO-2020" rel="noopener noreferrer" target="_blank">https://github.com/BFO-ontology/BFO-2020</a>.

What's so Basic about BFO?

With Dave McComb

This week we discuss the upper level ontology gist with its creator, Dave McComb.

Upper Ontologies: gist

with Chime Ogbuji

Chime Ogbuji joins me to talk about the role of medical informatics in knowledge graphs and semantics, all the way from MYCIN and GALEN to today.

What Does Medicine Mean?

An Opinion Episode

Properties are the workhorse of ontologies, where semantics really happen. So be careful when you make a new one!

Careful with that Predicate, Eugene!

With guests Keith Corbett and Grace Roessling

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.&nbsp; 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.&nbsp; References<ol><li>Larkin &amp; Simon (1987) -- list vs. diagrammatic representations (<a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1551-6708.1987.tb00863.x" rel="noopener noreferrer" target="_blank">https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1551-6708.1987.tb00863.x</a>)</li><li>Temple Grandin (2016) -- visual thinking, pattern mathematical thinking, and verbal/auditory thinking (<a href="https://www.jstor.org/stable/26407108?seq=3" rel="noopener noreferrer" target="_blank">https://www.jstor.org/stable/26407108?seq=3</a>)</li></ol>

What's So Hard to Understand?

With guest Deborah McGuinness

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.

What's an Ontology?

With Zara Waldman DeLuca

Today we flip the script: Prof. Zara Waldman DeLuca interviews Jamie on the fundamentals of knowledge graphs and ontologies, and they talk about some of the social, linguistic, and cognitive aspects of human vs machine cognition.

What are we talking about?

Exploring the world of Graph AI, ontologies, and knowledge graphs.

I'm Jamie McCusker, the host of The Opinionated Ontologist, a weekly podcast where I discuss Graph AI in all its forms (neurosymbolic AI, knowledge graphs, semantics, knowledge representation, and, of course, generative AI). I interview thought leaders in academia, industry, and culture who are researching, creating, and using graph AI to solve real problems. We discuss current trends and historical context, as well as provide introductions to concepts in Graph AI as needed. Since I am the Opinionated Ontologist, I also will add my own thoughts on topics in separate Op Ed episodes.
