I don’t know about Google, but Mike Lynch (Autonomy founder) eat your heart out! Having frequently used the WolframAlpha website I can testify to the fact that it is as close as you’ll get to a state of the art semantic web search engine. And it’s getting better the more data that it indexes and links. Who wants to pay for a half a £millon Autonimy licence when you can achieve much the same for free!
