Possibly the ultimate Next Big Thing in the history of computing, AI has been the dream of computer scientists since 1950 - when Alan Turing introduced the Turing test to test a machine’s capability to participate in human-like conversation. In the context of the Web, AI means making intelligent machines. In that sense, it has some things in common with the Semantic Web vision. We’ve only begun to scratch the surface of AI on the Web. Amazon.com has attempted to introduce aspects of AI with Mechanical Turk, their task management service. It enables computer programs to co-ordinate the use of human intelligence to perform tasks which computers are unable to do. Since its launch on 2 November 2005, Mechanical Turk has gradually built up a following - there is a forum for “Turkers” called Turker Nation, which appears to have light-to-medium level patronage. However we reported in January that Mturk isn’t being used as much as the initial hype period in Nov-Dec 05. Nevertheless, AI has a lot of promise on the Web. AI techniques are being used in “search 2.0″ companies like Hakia and Powerset. Numenta is an exciting new company by tech legend Jeff Hawkins, which is attempting to build a new, brain-like computing paradigm - with neural networks and cellular automata. In english this means that Numenta is trying to enable computers to tackle problems that come easy to us humans, like recognizing faces or seeing patterns in music. But since computers are much faster than humans when it comes to computation, we hope that new frontiers will be broken - enabling us to solve the problems that were unreachable before.
