Chatbot-Eliza (Eliza chat bot interface module for Perl) The original ELIZA program was written by Joseph Weizenbaum and described in the Communications of the ACM in 1967. Chatbot-Eliza is a clone of the classic ELIZA program written as perl module. It prompts for user input, and uses a simple transformation algorithm to change user input into a fellow-up question. The package includes some example scripts.
