Because of these advanced settings, PARRY got called “ELIZA with attitude.” It modeled the behavior of a paranoid schizophrenic while ELIZA just imitated the psychiatrist. Psychiatrist Kenneth Colby created this chatbot in 1972. The duo was used in psychiatry, helping to elaborate the dialogue strategy. ELIZA was meant to simulate a doctor, while PARRY was created to simulate a patient with schizophrenia. The chatbot ELIZA was used to act in a manner of a psychotherapist and was created to reproduce a conversation in an initial psychiatric interview.ĮLIZA gave room for the next step in chatbot development, a chatbot called PARRY. Typically, the chatbot would respond with “I see” or “I understand” when it couldn’t find a scripted answer. The chatbot could give itself away after several human-ish answers, basing on how the questioner ran the conversation. ELIZA examined the question for keywords and suggested a solution based on the keyword. It was designed to simulate a human conversation by matching the users’ inquiries with a list of possible scripted answers. The chatbot was created by an AI specialist Joseph Weizenbaum. We’ll start off with the ELIZA chatbot which was named after Eliza Doolittle from Pygmalion. The chatbot world is no different and run by the girl squad of ELIZA, A.L.I.C.E., Siri, Alexa, and co. The test had nothing to do with chatbots until 1966 when the first chatbot ever - ELIZA - managed to pass the test, and basically tricked a human into thinking it was a human too. If the questioner failed to tell the computer’s responses from the human’s most tries, the computer was considered to have artificial intelligence. The test refers to a method measuring whether the computer is able to mimic human intelligence under specific conditions.įor the actual test, a human had to blindly decide whether they got a response from a computer or another human. In the way we know them now, chatbots tap their hats to The Turing test - an imitation game introduced in 1950.
