Nowadays, when we think of chat robots, we think of ChatGPT ve Gemini Tools like these are coming, but about 60 years ago, another chatbot entered our lives: It was the world’s first chatbot. Of course ELIZAWe are talking about. Although ELIZA has not been with us for a long time, scientists managed to resurrect ELIZA from the lost original computer code.

ELIZA is alive!

This resuscitation attempt was made possible thanks to “software archaeology” studies on old technology and software. in the MIT archives old print documentsBy tracking down this lost code, he got ELIZA working again. MIT professor in the 1960s Joseph Weizenbaum Developed by ELIZA, it was named after Eliza Doolittle, the leading character in the theater play “Pygmalion”.

Eliza was a woman who learned to speak like an aristocratic Englishwoman. ELIZA was the first example of artificial intelligence that could interact with users as a language model and is stated to be one of the cornerstones of today’s artificial intelligence technology.

Initially, ELIZA functioned as a simple communication model that mimicked a therapist, responding to user input with questions and creating a dialogue that resembled sessions with human therapists. ELIZA’s most famous scenario, “DOCTOR”, answered questions like a psychotherapist and directed users to “Share your problem”. When the user said, “Men are all the same,” ELIZA asked, “In which way?” He was giving an answer like: This simple but effective artificial intelligence broke new ground in human-human interactions.

ELIZA, one of the first examples of artificial intelligence, was Weizenbaum’s own invention (which is no longer used).MAD-SLIP) was written in a programming language. However, with the porting of ELIZA to the Lisp language, it spread rapidly in the early days of the Internet, and the original version was forgotten over time. Experts say that ELIZA has 420 lines. thought his original code was lost. But in 2021, Stanford University cognitive scientist Jeff Shrager and MIT archivist Myles Crowley resurfaced the code they found in Weizenbaum’s personal papers.

Shrager, “I have a particular interest in how the early AI pioneers thought.” He underlined that ELIZA, for better or worse, was one of the cornerstones of early artificial intelligence. Shrager, “From a technical perspective, we didn’t even know that the code we found – the only version discovered so far – actually worked.” he said.

Bringing ELIZA back to life was challenging

Bringing ELIZA back to life was no easy task. The code had to be cleaned up, bugs removed, and an emulator created that resembled the computer architecture used in the 1960s. But despite all these difficulties, on December 21, ELIZA was fully Worked for the first time in 60 years. While resurrecting ELIZA, the research team also detected an error in its code, but they chose to fix this error in order not to spoil the essence of the work. This mistake actually sounds very simple today; The program crashes when a number is entered.

ELIZA, like modern large language models (LLMs) Although it does not have sophisticated featuresConsidering that it was written in 1965, it’s pretty impressive what it can do. According to Shrager, ELIZA is one of the modern chatbots The biggest difference was that it encouraged the user to continue the conversation. While today’s artificial intelligence generally tries to complete users’ sentences, ELIZA had a structure that directed the user to talk more.

As a result, ELIZA has been made available to the internet world using its original code. If you want to try Github You can download it from the link and try it. If you do not want to go to all this trouble, you can watch the video below.
