A chatbot named Mitsuku has won the Loebner Prize 2013, announced over the weekend, beating out three other contestants for the top prize of a bronze medal and $4,000. Mitsuku’s creator is Steve Worswick, Mitsuku’s botmaster. But wait a minute. What is a chatbot? A chatbot is a humanlike character with conversational skills which is simulated through artificial intelligence. Eliza, back in 1964 and 1966, was the first step into programmed chatterbots, designed to simulate a conversation with one or more human users. The Eliza program was based on a human mode of interaction typified by a Rogerian therapist trained not to make any creative input to a conversation, but instead only to keep it going so that patients could explore their own feelings. “Talking to Rogerian therapist is very like talking to a brick wall with a slightly clever echo,” wrote Mike James in iProgrammer. But wait another minute. What is the Loebner Prize? This is an annual competition created by businessman Hugh Loebner. The competition is an embodiment of the Turing-test affair; the chatbots try to fool the judges into assessing their answers are from humans. With reference to mathematician Alan Turing in the 1950s, the contest sets out to stage an event around Turing’s suggestion that if a computer answered questions as convincing as a human could, then the machine could reasonably be said to be thinking. The Turing Test emerged as a way to assess the intelligence of computer programs. Loebner has offered a prize of $100,000 for the computer program that meets Turing’s standard for artificial intelligence but no chatbot creator has ever achieved that level and the top-tier cash has gone unclaimed. The four finalists at the 2013 event in Northern Ireland had to undergo four rounds of questioning with the competition judges. The Mitsuku chatbot as conversationalist was declared the most convincing.
Person or computer: could you pass the Turing Test?
As mentioned already on this site and others, this year marks the 100th anniversary of the birth of famed British mathematician Alan Turing. The outline of his remarkable life and sad ending has by now become fairly well known. Turing laid numerous foundation stones of modern computing, ranging from the deepest mathematical nature of computing (using what are now called Turing machines he provided the modern approach to incompleteness and undecidability) to specific issues of practical design; he also contributed to mathematical biology (morphology) and much else. At the same time, he played a key role in the British government’s breaking of the German Enigma code at the now-fabled but then ultra-secret Bletchley Park, thus arguably accelerating the end of the second world war.

Interest is now reviving in artificial intelligences that are able to imitate humans, thanks to revolutionary advances in technology, such as microchips that mimic brain cells, researchers say. The idea of computers advanced enough to perfectly mimic humans was most famously proposed by British mathematician Alan Turing, who helped the Allies win World War II by breaking top-secret Nazi codes. “Turing was without any question one of the founders of the modern computer age,” said Robert French, research director of cognitive science at the French National Center for Scientific Research.”He was an absolute genius. I don’t use that word very often, but he was.” (via How New Tech Is Reviving Hope of Humanlike Computers | Innovationnewsdaily.com)
