Dao -- An interactive knowledge base, natural language interpreter.
Copyright (C) March 25, 2009, Ramin Honary

This program is my first attempt to re-write my entire Master's thesis
as a Haskell program. It was initially written in C, and then when I
realized I couldn't finish my project in time making it in C, I switched
to Perl. I completed my thesis, but I was largely unsatisfied with my
work and continued to make improvements. Then I discovered Haskell and
decided it was the best way to make it work. I would like to publish the
work I have completed so far so I can continue to make improvements
publicly and with an open source license, the GPL.

Dao is an artificial intelligence program which allows users to construct
a knowledge base for intepreting natural language input. The idea is to
let users interactively build their own knowledge base by adding rules at
runtime.  The state of the knowledge base can be updated by enacting it's
own production rules, or by a user entering commands to alter the state
directly. Regular-expression-like patterns are associated with rules so
natural language input can be used to invoke rules at any time.

Because the knowledge base is built interactively, it is very simple to
define a new regular expression production rule and test it out
immediately, to see if it interferes with other production rules in the
knowledge base, or to see if the regular expression was defined
correctly.

A future release of this program should be able to deduce regular
expressions and production rules without requiring the users to define
regular expressions directly.
