That was a very interesting paper. I really liked their approach to
reference resolution - that of keeping a stack of everything that
was talked about along with some semantic flags (word gender,
number, etc.), and then matching ambiguous references such as
pronouns to the topmost entry on the stack that satisfied the
flags. That's nice - it should be *really fast*, and catch the vast
majority of pronoun and other references. And surely it won't catch
everything, but that's ok, we can always ask the player for
clarification. :)

Thanks for the link!
