Relied on non sequiturs in conversation.Winning programmer: Joseph Weintraub’s program PC Therapist III.Eight cases in which a computer was misclassified as human.Five judges rated the top contestant as human.To give the computers a fighting chance, contestants were allowed to select a single topic to converse on.Judges had short conversations with each contestant and rated their human-ness.1991: 10 judges and 8 contestants (6 computers and 2 humans).Machines are programmed to carry on a conversation with the user.Expands this to a computer convincing an interrogator that it is human.Turing described an “imitation game” in which a man and a woman both try to convince an interrogator that he/she is the woman.Turing’s 1950 paper “Computing Machinery and Intelligence.” The Turing Test Conversational AI and the Loebner Prize Competition Jen Brandner for CSCI 405
