"We have this research project going which we call our Never-Ending Language Learner (or NELL for short), and the goal here is to build a program that runs 24 hours a day 7 days a week and everyday it has two things it has to do."

"The hardware is a collection of about a hundred computers that Garth Gibson (another faculty in our department here), runs as a research project and he lets us use that collection to run NELL....Maybe more interesting than the hardware is how the learning itself works and I could take a few minutes to explain that"
"They have (in a funny way) a more complete factual set knowledge than a normal three year old, but they still dont have that kind of common sense that a 3 year old has"
"Lets say I give you the word mom or computer....its really the same brain and the only difference is that when I say the word mom it was one pattern of neurons firing and when I say computer it is a different set of neurons firing in your brain.
