Josh, I have no idea how new the idea is. When Schank was talking about
scripts ...
From the MIT Encyclopedia of the Cognitive Sciences (p729):
"Schemata are the psychological constructs that are postulated to account
for
the molar forms of human generic knowledge. The term *frames*, as introduced
by Marvin Minsky (1975) is essentially synonymous, except that Minsky used
frame as both a psychological construct and a construct in artificial
intelligence. *Scripts* are the subclass of schemata that are used to
account
for generic (stereotyped) sequences of actions (Schank and Abelson 1977)."
Josh,
Yes but the image schema of Mark Johnson & co, are literally outline
graphics - something like, say, a point or blob - an arrow - and another
point or blob - for "X journeys to Y [a goal]" . [See The Body in the Mind]
The schemata of Minsky & co, as I understand, are networks of symbolic
concepts - and haven't worked. And - correct me, because I only have a vague
knowledge here - my impression is that everyone who is currently trying to
draw analogies - e.g. Hofstadter, Gentner, Ben - is also relying on some
form of symbolic networks.
This whole area is v. confused and difficult to discuss, precisely because
it involves visual images. For example, Johnson Laird's "mental models," as
I understand, partake of both visual elements and symbolic concepts - but it
often isn't clear which. It also often isn't always clear in Minsky's work
whether he might not mean something more visual by scripts, though in fact
he definitely works just with symbols.
I - and perhaps Johnson & co - am arguing that this whole area is extremely
important. You could say that image schema/ graphics are the mind's
informal geometry - and are central to its power to do almost all the things
that AGI is currently incapable of - like drawing analogies, visual object
recognition and visual thinking AND NLP - and, one might add, the mind's
technically extraordinary ability to construct altogether new visual scenes
and scenarios in dreams.
(I - & again, I think, Johnson & co - don't think the mind works with just
image schemas, but also with more detailed images - as the example of dreams
indicates. Schema/graphics are the visual and sensory storyboard which
allows the mind to then flesh in more detailed images).
