The Opinionated Ontologist
Hosted by Jamie McCusker · EN
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.

What's in a Triple?
May 2300:49:42Tap to summarizeWe 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. Hosted on Acast. See acast.com/privacy for more information.
Transcribe →KGC-palooza!
May 9, 202500:49:42Tap to summarizeThis 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.

Transcribe →What's so Basic about BFO?
May 6, 202501:09:41Tap to summarizeWe 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.

Transcribe →Upper Ontologies: gist
Apr 12, 202500:48:37Tap to summarizeThis week we discuss the upper level ontology gist with its creator, Dave McComb. Hosted on Acast. See acast.com/privacy for more information.
Transcribe →What Does Medicine Mean?
Apr 6, 202500:53:00Tap to summarizeChime 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. Hosted on Acast. See acast.com/privacy for more information.
Transcribe →Careful with that Predicate, Eugene!
Mar 26, 202500:22:08Tap to summarizeProperties are the workhorse of ontologies, where semantics really happen. So be careful when you make a new one! Hosted on Acast. See acast.com/privacy for more information.
Transcribe →What's So Hard to Understand?
Mar 20, 202501:19:15Tap to summarizeKeith 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.

How does RAG work with KGs?
Feb 26, 202501:07:26Tap to summarizeToday I was joined by David Hyland-Wood to discuss how Retrieval-Augmented Generation (RAG) works with Knowledge Graphs. We also talked about LLM bullshit, and the relationship between RAG systems, knowledge graphs, and open-source large language models, and explore the importance of modeling knowledge graphs for effective output.
