I’ve just found on Twine a video of a very interresting presentation at Google TechTalks, May 30, 2006, by Dr. Douglas Lenat, the President and CEO of Cycorp.

In this presentation, Dr. Lenat shows to googlers how the OpenCyc ontology make computers able to compute answers to simple questions that Google cannot answer because it does not understand their meaning. It is a very good presentation of semantics, common sense AI with many clear examples and a very good speech. I recommend it to people who are curious about the semantic web, ontologies and stuff.
