This javascript version of ELIZA was originally written by Michael Wallace and enhanced by George Dunlop.Eliza was developed by Weizenbaum at MIT between 1944-1946 as a chatterbot program that analyzed sentence fragments to return predefined Rogerian phrases. And, as with Siri, Alexa and other operating system disembodied voices, feel free to conjure up your own idea of what ELIZA looks like. You can sit on your own couch and pretend it is a therapist's couch. (The episode, "A Computer, a Plastic Pony, and a Case of Beer," may still be available at Sheldon and his family become quite enamored by ELIZA, though the precocious Sheldon quickly realizes it is a limited program.
ELIZA FROM HEY ELIZA TV
She is still a baby chatbot, but she has had a 2018 resurgence of interest because she was featured in an episode of the TV show Young Sheldon. The version of ELIZA below is a more recent javascript incarnation to which I have made some cosmetic and scripresponset changes. Luckily, I never received any parent phone calls about it. They were delighted and set to work immediately. "You would have to if you want her to really respond logically, " I concluded. "We can do that?" they asked rather incredulously. But you'll need to type in every possible curse word so that she knows what to respond to." Someone would tell ELIZA to do something obscene and she might answer "We were discussing you, not me," which is actually pretty clever and funny - by accident. I said, "She will respond based on some word you use, but she won't know those kinds of words." One particularly memorable moment was when a student asked "What happens if someone types in a curse word? "
ELIZA FROM HEY ELIZA CODE
That said, ELIZA delighted my students, and those who were in my little programming club at that time were also delighted to make their own versions by revising and adding to the code and scripts. By today's standards ELIZA fails very quickly if you ask it a few complex questions.
It was also an early test case for the Turing Test, a test of a machine's ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. In this instance, the therapist "reflects" on questions by turning the questions back at the patient.ĮLIZA was one of the first chatterbots (later clipped to chatbot). This was made to respond like a Rogerian psychotherapist. Perhaps the most well known variation was called DOCTOR. (ELIZA was originally written in MAD-Slip.) Many variations on the original scripts were made as amateur coders played around with the fairly simple code.
The program was limited by the scripts that were in the program. Using "'pattern matching" and substitution methodology, the program gives canned responses that made early users feel they were talking to someone who understood their input. But, when it was put on personal computers, humans found it quite engaging.
It supposedly had been created to demonstrate how superficial human to computer communications was at that time. This early natural language processing program had been written in the mid-1960s at the MIT Artificial Intelligence Laboratory by Joseph Weizenbaum.
ELIZA FROM HEY ELIZA SOFTWARE
By then, ELIZA was a software tween herself. I first encountered ELIZA on the Tandy/Radio Shack computers that made up the first computer lab in the junior high school where I taught in the 1970s. Talk to Eliza by typing your questions and answers in the input box.
