Thanks Arckon for offering any help, but I'm having my mind (for a long time now) on a different project. Maybe when I've got loads of time I'll pick it up again (Being when my pension starts, 50 years or so!;-)...

I think I was thinking further than you are. I was (still am) very interested in a way of storing and linking all data that the avatar receives to form a reply.

Little example of what I wanted to end up with:
human : "Do you like dogs"
avatar: "Yes"
human : "Why?"
avatar: "Because they are fluffy and warm"

Sure, you can feed the avatar with the logic that a dog is likeable because it is fluffy and warm... But than that would be simply something YOU "taught" the avatar with. Imagine that a friend enters the keyboard and he does not like dogs. He asks the same thing

human : "Do you like dogs"
avatar: "yes"
human : "Dogs are not nice animals"

Now what does the avatar do? Keep it's first data which you taught 'em, or replace it with your friend's opinion of dogs?

See the problem? I wanted a system that takes facts and makes up his own opinion about ie. dogs. You can tell 'em properties of a dog, different races of dogs, different behaviours of dogs and the avatar would make it's own decision based on LOADS of things whether it likes dogs or not...

If you keep on thinking about this, you probably end up stuck with the question: "Are all things based on *facts* or *opinions*?"

...Basically I took the avatar idea way beyond text/grammar recognition and tried to find out a good basis for the "intelligence"...
