The “knowledge engine”

(BBC): A web tool that "could be as important as Google", according to some experts, has been shown off to the public. Wolfram Alpha is the brainchild of British-born physicist Stephen Wolfram. The free program aims to answer questions directly, rather than display web pages in response to a query like a search engine. The "computational knowledge engine", as the technology is known, will be available to the public from the middle of May this year. "Our goal is to make expert knowledge accessible to anyone, anywhere, anytime," said Dr Wolfram at the demonstration at Harvard University’s Berkman Center for Internet and Society.
