Yeah. I've never read Buzan's book, but from my undesrtanding, he came
up with the term.
Well, there's definitely some overlap. I realize now that plato is really
1. A tool or library for drawing mind maps/ network graphs / whatever
.. It should handle layout and all that stuff for these objects..
Also, you shold be able to pick them up, move them around, and have
the lines do the right thing.
There's a TCL project called Mercator that sort of does this, but
i'm nos sure how far along this is.
2. A generic inference engine / expert system / reasoning system.
3. A tool for socratic thinking / exploration.

It sounds like you're pretty intersted in this aspect!
To me, I'm only looking at the reality tree (a specific subclass of
these diagrams) as a way of visualizing an actual process that the
computer (or a live teacher!) would go through.
For example, if the goal is to teach recusion, and the example is
the fibonacci sequence, it's important that the student understand
how the sequence works. So in a socratic dialog, you might ask:
"what's the next number in this sequence? 0 1 1 2 3 5 8 13 21 ..."
And the student can either answer or ask for help. If they answer
correctly, we don't have to walk down the part of the tree that
explains fibonacci's sequence. We just say "that's called fibonacci's
If they answer wrong or ask for help, we back up and ask more
questions that can help them figure out how the sequence works.
(or just explain it to them)..

Yeah, I'm a brain user... Unfortunately, they own the patent for this
type of software, so plato will probably stay away from that.. Besides,
there's plenty of stuff you can do with just plain 2D. :)

Mercator uses an XML format to describe its nodes....
There's also the Neural Integrator, which might have some
interesting pieces we could steal.. I haven't tried it yet though:

Not sure I agree with you on this.. Depends what you mean by "rigid",
I guess.. Many people often find themselves in the same situations
over and over again, thanks to our nervous system's wonderful ability
to learn and form habits.. Obviously, you can't control every single
thing that happens to you, but for ongoing or recurring problems,
there usually is a logical cause..

Doesn't let you play with the graphs. Just shows how a
program navigates through one.. Kinda cool though, and might
be useful for debugging.
There's also a language calle Oz (www.mozart-oz.org) that includes
a graphical tool for debugging logic programs with constraints..

Would be pretty cool if we could have arbitrary shapes for stuff...
Maybe even based off of SVG descriptions.. All I'm looking for is
boxes, but I can see how lots of people would find this useful.

Hey! Now that's cool! I'll have to check that out.
