Ontology - why should you care?

This talk presents an overview of ontology, including how formal ontology compares to less formal approaches and how the Suggested Upper Merged Ontology (SUMO) ( compares to other formal ontologies. Classes of ontology-based applications are introduced. Issues of the capabilities and tradeoffs in first order logic inference are explored. The SUMO is also described in detail, along with its mappings to the WordNet lexicon.


Adam Pease has led research in ontology, linguistics, and formal inference, including development of the Suggested Upper Merged Ontology (SUMO), the Controlled English to Logic Translation (CELT) system, the Core Plan Representation (CPR), and the Sigma knowledge engineering environment. Sharing research under open licenses, in order to achieve the widest possible dissemination and technology transfer, has been a core element of his research program and his products have been downloaded by thousands of people around the world. He is the author of the new book “Ontology: A Practical Guide”

    Very nice talk by Adam Pease. Nice to know that SUMO has grown into a very useful set of ontologies.

    This was a terrific technically thorough presentation. The field of Ontological modeling is a notorious prickle patch. I was very impressed with the speaker's abilities to (1) explain SUMO thoroughly and clearly (2) answer critical comments thoughtfully and deeply and (3) refuse to be drawn into any of the frustrating ideological arguments that characterize most discussions of these issues. Bravo, Adam!

    Just wanted to let you know that this Microsoft Facility is the Research Facility, not the main campus. Please double check the address above. Plus, it would be easier if you would park on the back side of the building. Someone will be at the door. Looking forward to it.
