David,
Thanks for reply. Like so many other things, though, working out how we
understand texts is central to understanding GI - and something to be done
*now*. I've just started looking at it, but immediately I can see that what the
mind does - how it jumps around in time and space and POV and person/subject -
and flexibly applies its world/subworld models - is quite awesome.
I think the word/sentence focus BTW is central to cognitive science *and* the
embodied cog. sci. of Lakoff and co. as well as AI/AGI.
But the understanding of language understanding will only really come alive
when we move the focus to passages - and how we use language to construct a)
stories b) arguments and c) scenes (descriptive passages). [I wonder whether
there are any other major categories of language].
It also entails a switch from just a one-sided embodied POV to a two-sided
embodied-embedded overview, looking at how language is embedded in the world.
To focus on sentences alone is like focussing on the odd frame in a movie. You
can't get the picture at all.
A passage/text approach will v. quickly answer Matt's:
"I mean that a more productive approach would be to try to understand why the
problem is so hard."
David:
How does Stephen or YKY or anyone else propose to "read between the lines"?
And what are the basic "world models", "scripts", "frames" etc etc. that you
think sufficient to apply in understanding any set of texts, even a relatively
specialised set?
(Has anyone seriously *tried* understanding passages?)
That's a most thoughtful and germane question! The short answer is no, we're
not ready yet to even *try* to tackle understanding passages. Reaching that
goal is definitely on the roadmap though, and there's a concrete plan to get
there involving learning through vast and varied activities experienced over
the course of many years of practically continious residence in numerous
virtual worlds. The plan indeed includes the continuous creation, variation and
development of mental world-models within an OCP-based mind. Attention
allocation and many other mind dynamics (CIMDynamics) crucial to this
world-modeling faculty must be adequately developed, tested and tuned as a
pre-requisite to begin trying to understand passages (and, also to generate and
communicate imagined world-models as a human story teller would do; a curious
byproduct of an intelligent system that can reason about potential events and
scenarios!)
NB: help is needed on the OpenCog wiki to better document many of the
concepts discussed here and elsewhere, e.g. Concretely-Implemented Mind
Dynamics (CIMDynamics) requires a MindOntology page explaining it conceptually,
in addtion to the existing nuts-and-bolts entry in the OpenCogPrime section.
