Dear All,
Whilst agreeing with John, I'd like to approach this from the other end of
the telescope. First some basics:
1. For each concept there is a set of objects that it describes.
2. A concept is primitive unless it is the intersection of 2 or more other
concepts. (01)
The proposition is that there is some moderate set of primitive concepts
such that there is no useful concept that cannot be defined as the
intersection of that set of primitive concepts. (02)
Now consider the number of objects there are that we might want to describe.
Consider our universe, the galaxies, planetary systems, stars, planets,
moons, other bodies, parts of these, life, molecules, atoms, subatomic
particles. Then there are all the other possible universes, with unicorns
and so on. (03)
So you need to prove that there is a number of primitive concepts, n, where
n is (a lot) less than infinity, such that it is not possible to come up
with some useful set of all these objects that is not the intersection of
some of those n concepts. (04)
It does not seem credible to me that there is any such number, but I look
forward to seeing any proof that such a number exists. (05)
Regards (06)

Yes. I cited Anna Wierzbicka's _Lingua Mentalis_ in my 1984 book, and I've
followed her other books over the years. I call her primitives 'accordion
words' -- because you can stretch them and squish them to fit anything you
please. (011)
They're useful. To quote my favorite philosopher, C. S. Peirce:
> It is easy to speak with precision upon a general theme. Only, one

> easy to be certain. One has only to be sufficiently vague. It is not
> so difficult to be pretty precise and fairly certain at once about a

Again, I recommend that every reader of this list *study* the paper "I don't
believe in word senses." Adam K and Sue A are *professionals* in
lexicography and computational linguistics. They know the difference
between accordion words and precise definitions. Both can be useful for
different purposes, but it's important to know the difference. (013)

Brief answer: (015)
1. There is no "basic agreed level" whatsoever -- NONE! (016)
2. The top level of an ontology *must* be vague and underspecified.
It can be useful, but the real knowledge is in the lower levels. (017)
3. Please remember that Cyc started out with the assumption that a
formal ontology of the knowledge of a high-school graduate could be
specified in 10 years. After 30 years and over $100 million of
investment, Doug Lenat has emphasized that all the real knowledge
is in the detailed low levels. The top level is very vague and
underspecified. It cannot support any kind of detailed reasoning. (018)

If that's your definition, then you're talking about the empty set.
There is no concept or thought of any kind that cannot be analyzed at a
deeper level. (020)
> So John S, to take your examples... (021)
I was just trying to give one-line examples. In any case, the terms in your
analyses are accordion words. Please study that paper by Adam K. (022)

Yes! But I would avoid using the word 'core' because it gives the mistaken
impression that some kind of core is possible. But even for farming and
offices, the basic terms are accordion words. Note how we use the
abbreviation 'cc' in our emails. In office-speak, it used to mean 'carbon
copy'. When was the last time you saw a carbon copy? (024)
PC
> according to Guo, the number of senses used **in the definitions**
> average to less than 2. (025)
If so, Guo doesn't know how to define words or to count definitions.
I suspect he was using those terms as accordion words. If you stretch and
squeeze them enough, you can adapt them to almost anything. (026)
But with every stretch and squeeze, you blur an immense amount of info.
Please tell Guo to study Adam K's paper. Also study the publications about
*microsenses* by Alan Cruse. A microsense is any intermediate point as you
stretch and squeeze your accordion. (027)
PC
> If anyone knows of such a study, I would very much like to get a pointer. (028)
I've given you many, many pointers over the years. And I beg you to study
them until you reach enlightenment. For starters, please reread
http://www.jfsowa.com/talks/goal3.pdf and *follow* every URL to every
reference in it. (029)
Those other goalX.pdf files are also surveys. You have to dig into the
references until you get the point. Anything that looks like or smells like
a primitive is probably an accordion word. (030)
