ELIZA-Smalltalk
===============

**Smalltalk ([Pharo](https://www.pharo.org/)) implementation of [ELIZA](https://en.wikipedia.org/wiki/ELIZA), an early natural language processing computer program created from 1964 to 1966 at the [MIT Artificial Intelligence Laboratory](https://www.csail.mit.edu) by [Joseph Weizenbaum](https://en.wikipedia.org/wiki/Joseph_Weizenbaum).**

This implementation is based on [this Python implementation](https://web.archive.org/web/20200424191830/https://www.smallsurething.com/implementing-the-famous-eliza-chatbot-in-python/) and [elizabot.js](http://www.masswerk.at/elizabot/) (for the welcome messages). There are similar implementations for [Go](https://github.com/kennysong/goeliza) and [Swift](https://github.com/kennysong/SwiftEliza).

* [Pharo 10](https://www.pharo.org/) reference platform.
* Examples and tests included.
