JZBot is an IRC bot written in Java. It's almost entirely factoid based, with a turing-complete (but simple) factoid language that allows everything from its roulette command to its weather command to be written as factoids. It even allows administrators to start an HTTP server that can access factoid data; this could be used, for example, to make karma stats publicly available.
The official instance of JZBot resides at irc.freenode.net using the nickname Marlen_Jackson.

Note that the source code analysis provided by Ohloh is way skewed as JZBot's repository contains copies of the source code of several other libraries (such as H2 and Pircbot) since it uses a modified version of these libraries.
