http://Alicebot.org Certainly the most active OpenSource JavaLanguage ChatBot. ''Yep'' Not just JavaLanguage. There are multiple implementations. I've used/modified the Perl version extensively, for instance. There's also a Lisp version. They're all based on the AIML knowledge representation language, which is XML based. ''The AliceBot developers have released a bunch of code under the GNU Lesser GPL ( http://alicebot.blogspot.com/2013/01/program-ab-aiml-20-reference.html ).'' ---- ''"The C''''''allMom is now available free in the Android Market, with limited learning features. A premium upgrade is underway which will make the learned knowledge persistent."'' That doesn't meet my requirements for Open Source. What a scam. CategoryRipoff ''So what are your requirements for OpenSource?'' ''Which requirement in particular do you think is not being met?'' ''Do you realize there is a difference between OpenSource vs. FreeAsInGratis?'' ''If not, you may be surprised at what the FSF says about Selling Free Software ( http://www.gnu.org/philosophy/selling.html ).'' ---- CategoryOpenSource
