The biggest internet revolution for a generation will be unveiled this month with the launch of software that will understand questions and give specific, tailored answers in a way that the web has never managed before…

Tom Simpson, of the blog Convergenceofeverything.com, said: “What are the wider implications exactly? A new paradigm for using computers and the web? Probably. Emerging artificial intelligence and a step towards a self-organising internet? Possibly… I think this could be big.”

Wolfram Alpha will not only give a straight answer to questions such as “how high is Mount Everest?”, but it will also produce a neat page of related information – all properly sourced – such as geographical location and nearby towns, and other mountains, complete with graphs and charts.
