IBM developerWorks: Doug Lenat on Cyc, a truly semantic web, and A.I. - Part 2

Doug Lenat is a prominent researcher in artificial intelligence and founder of the CYC project -- a very large, multi-contextual knowledge base and inference engine intended to provide a "deep" layer of understanding that can be used by other programs to make them more flexible. Doug talks about where Cycorp is in pursuit of that goal, and talks about the vision of a truly sematic web.
