To understand the Python project on ELIZA, we need a bit of background.
ELIZA is a computer program designed to simulate human-like conversation by using natural language processing techniques. It was created by Joseph Weizenbaum in 1966 at the Massachusetts Institute of Technology (MIT) and is considered one of the earliest examples of a chatbot.
The program was named after the character Eliza Doolittle from the play “Pygmalion,” who undergoes a transformation from a working-class girl to a refined lady through language training.
ELIZA works by analyzing the user’s input, searching for keywords, and using pre-programmed rules to generate responses that mimic those of a therapist. It was designed to simulate a Rogerian psychotherapist, a type of therapist who emphasizes empathy and reflection rather than offering direct advice or solutions.
ELIZA became famous in the late 1960s and early 1970s, as it was one of the first programs to create the illusion of a human-like conversation. It has since inspired numerous chatbots and conversational agents, and its legacy can still be seen in the development of modern AI-powered chatbots and virtual assistants.
ELIZA can be a fun programming project to make because it allows you to explore and experiment with natural language processing techniques and simulate human-like conversation. The project can also be a great opportunity to learn about rule-based programming and develop your programming skills.
Creating an ELIZA program can be challenging, as it requires analyzing and interpreting user input, identifying keywords and patterns, and generating appropriate responses. However, it can also be rewarding to see your program engage in convincing conversations with users.
Moreover, because ELIZA is a well-known and widely studied program, there are many resources and examples available online to help guide you through the process of creating your own version of the program. This can make the project more accessible and enjoyable for beginners and experienced programmers alike.
Overall, ELIZA can be a fun programming project to make because it allows you to explore the fascinating world of natural language processing while creating a program that can simulate a human-like conversation.
It looks for simple patterns and substitutes to give the illusion of understanding from the computer (wiki).
I need cakeit can look for a pattern
I need *
Why do you need cake?
This can be done simply as follows.
eliza_response = 'What do you need?' while True: s = input(eliza_response + ' ') if 'I need ' in s: your_need = s.split('I need ')[-1] eliza_response = 'Why do you need ' + your_need + '?' elif 'because' in s: your_cause = s.split()[-1] eliza_response = 'Why are you ' + your_cause + '?' elif s == 'quit': break else: eliza_response = 'Can you tell me why?'
This can generate the following dialog.
What do you need? I need cake Why do you need cake? because I am hungry Why are you hungry? because it makes me less irritated Why are you irritated? because I need to avoid low blood sugar Why do you need to avoid low blood sugar? because I need a reward Why do you need a reward? because I was good Why are you good? because I need to learn Python Why do you need to learn Python? because I need a job Why do you need a job? quit
You can expand on this idea to make the conversation more real.
