Turing test

n. The Turing test invented by the British mathematician Alan M. Turing in 1950 gauges whether an artificial symbol-processing system (e.g., a computer program) is intelligent. The basic idea behind the test is whether an observer engaged in non-face-to-face conversation with both the symbol-processing system and a human by means of teletype machine (or, more recently, chat room) can distinguish one from the other. As Turing theorized it, if the system can so effectively simulate human responses that 30% of observers during a 
5-minute test cannot reliably discern whether they are dealing with a computer or a person, then the system passes the test. According to Turing, any artificial system capable of passing the test should be considered capable of human intelligence. – AK
