True Knowledge, ‘plain English’ answers engine, has today launched its open beta. Back in September the site won around £600,000 in backing from Octopus Ventures. Developed by AI software developer and entrepreneur William Tunstall-Pedoe, True Knowledge is out to change the way factual information is made accessible via the Internet. By structuring facts in a way that machines and humans can easily understand, its tool is able to provide an intelligent response to questions without human intervention. In other words, you put in a question and it’s supposed to answer like a human. That’s what it says on the tin, but obviously one can see this being a fairly interesting Enterprise 2.0 application.
