a test proposed in 1950 (originally called the imitation game) to determine in what situations a computer program might be said to be intelligent. A person is isolated in a room but is connected to either a computer or another person outside the room. If the person in the room cannot tell, by asking questions, whether he or she is talking to the computer or to the other person, then the program on the machine must be seen as intelligent. See also Chinese Room argument. [Alan Turing]
