In 1964 a man named Joseph Weizenbaum decided to write a script that simulate a human. This script was named 'ELIZA', after Eliza Doolittle from Pygmalion, as you could teach it to talk in many ways. Eliza was a great success. This script is based off of a python version of the script. The original patterns have been simply dumped and copied using the import to list function of scratch. I'm very surprised at the size of the scripts.
This is a small chatbot based on Eliza.py: http://www.jezuk.co.uk/cgi-bin/view/software/eliza Further reading: https://en.wikipedia.org/wiki/ELIZA Created as part of an english computer science GCSE.
