Certainly not ALL of it. I hadn't looked at this before, so I spent some
time browsing the write-ups, examples, etc.
I'm not sure. You obviously know a lot more about this site than I do.
I'll make some impressionistic comments to show what *I* got from the
web site and allow you to correct me.
What I saw from the web site was more of a dictionary than a common
sense sort of thing. Maybe they just picked poor examples, or perhaps
they did them poorly. If you have access to the actual database, perhaps
the best test would be to take my list of examples and find the closest
fit to each of them you can. If, say, half of them can be found in the
database, then you might infer that with twice the number of common
sense facts that you would have at least the common sense of a
To illustrate, they presented the entry for "RoadVehicle" indicating
that they are designed to travel on roads. Of course, the fact that they
are "designed" at all is a bit off the subject, and certainly some
RoadVehicles are doubtless made freehand with a torch (I know a guy who
does this, a sort of "Road Warrior", with less than a grade school
education). The key point is that they DO travel on roads, which wasn't
at all clear from the entry. Further, such vehicles have some other
common characteristics, e.g. they have exactly one driver, they are
painted, they have windows, headlights, bumpers, and other things
required by law, they travel on tires made of rubber, etc.
As Joe Devin noted in a recent posting, one of THE most important things
to know is WHAT characteristics of a noun phrase are modifiable. Without
this, you cannot successfully parse any but the simplest of sentences.
For example, it would be very useful to know that RoadVehicles have
color, and that red is a color, so if you see red and RoadVehicle in the
same sentence, you can semi-safely presume that one modifies the other,
though there ARE exceptions, e.g. "The red man drove the RoadVehicle."
Of course, here, men can have certain colors, e.g. red, white, and
black. Other colors like blue can infer something other than color, e.g.
sadness, e.g. in "The blue man drove the RoadVehicle.", what color is
the man? Almost certainly NOT blue!
Compare "A bright and shining red caught my eye, as I watched the man
drive the fire engine." to "The black was definitely out of place - as I
watched the New Orleans refugees at the Houston Astrodome." In each of
these sentence, the color applies to a completely different part of the
sentence because we know that fire engines are red and the Houston
Astrodume is not black. Imagine the sorts of common sense knowledge
needed to figure THAT out.
I can STILL remember an incident when I was 5 years old. My mother had
taken me for my first ride on a Seattle transit bus, and a black man
climbed aboard - the first one that I had EVER seen. I pointed to him
and announced in a loud voice "Look at that dirrrrrty man over there!"
as my mother quickly wrapped her hand over my mouth and explained in a
whispering voice that some people are actually BORN that way! Sometimes,
important common knowledge is learned late.
Perhaps what is needed is a gigantic e-book of common sense knowledge
(who needs an API?!), that everyone just feeds into their NL program and
then checkpoints the tables in preparation for human use.
Of course, trying to actua
