This could be interesting - from the guy who created Mathematica - a plain language factual question answering system.
"It's going to be a website: www.wolframalpha.com. With one simple input field that gives access to a huge system, with trillions of pieces of curated data and millions of lines of algorithms.
We're all working very hard right now to get Wolfram|Alpha ready to go live.
I think it's going to be pretty exciting. A new paradigm for using computers and the web.
That almost gets us to what people thought computers would be able to do 50 years ago!"
