A long-time traveller in knowledge science (PhD in AI in 1990, worked at five different AI labs in Europe between 1990-1996, co-founded a company in the mid-90's that tried to invent the Semantic Web when the standards were just a gleam in the eye of a few W3C folks), I am now working as a consultant for TopQuadrant Inc. as their Semantic Web expert. Though I run the training course, I learn more from the students than they ever guess.

My laptop is full of semantic web software, and I even know how to use more than half of it. It's an exciting time for those of us who have been fans of abstraction for the past three decades.
