Description:

megahal is a conversation simulator that can learn as you talk to it
Conversation simulators are computer programs which give the
appearance of conversing with a user in natural language. Such
programs are effective because they exploit the fact that human beings
tend to read much more meaning into what is said than is actually
there; we are fooled into reading structure into chaos, and we
interpret non-sequitur as valid conversation. MegaHAL differs from
conversation simulators such as Eliza in that it uses a Markov Model
to learn how to hold a conversation. It is possible to teach MegaHAL
to talk about new topics, and in different languages.
