Six computer programs will compete for the $100,000 and a gold medal Loebner prize in order to pass the Turing Test. The test was devised half a century ago by the great mathematician Alan Turing. The procedure of test is simply to be able to recognize a computer program from a human speaker, without knowing who behind the curtain is. If the computer program is able to deceive the human judges that they believe they are talking to a human, the computer program is considered successful. For more please see the link below.
