Re: Pickup Line Puzzle

Well, here is an attempt to simplify the relevant aiml. Not all
supporting categories are present but hopefully it demonstrates the
concept adequately.

Some background. This was developed as part of an on going study, by Bob
Heller at Athabasca University, into the application of historical
figure conversational agents in distance education. A few famous names
from the field of Psychology are represented by Freudbot, Piagetbot, and
Skinnerbot.

Part of the challenge in using a conversational agent for education is
keeping the conversation "on topic" (referring to the subject, not an
aiml topic). One of the methods for addressing this is to identify when
multiple consecutive non-matches occur.  Basically, the pre-processor
approach allows us to apply conditional(s) to every user input.

The extra aiml processing associated with this is significant but does
not seem to cause a problem in response times as a rule.

If you'd like to try it out, visit Freudbot's office in SecondLife:

Yes, I'd like to see it.  Is it too long to publish here?
