FYI.    (01)

For a *completely* different take on "measuring semantic distance",
see ieml.org , and click on "Dictionnaire".  Although it may not be
obvious at that website, what Pierre LÚvy (Canada Chair for Collective
Intelligence, U. of Ottawa) has done there is to propose an address
space within which every kind of human transaction (political,
spiritual, literary, etc ...) has a unique and well-grounded address.
The fact that all addresses are expressed in terms of two dialectics,
one with three poles and one with two poles, is what makes the
distances in the space "measurable".  (Although the multiple possible
approaches to the making of actual measurements based on these poles
is an area of ongoing research.)  It's not yet completely clear to me
how the grounding actually happens, but I'm convinced that it's
happening in at least *some* minds.      (02)

Regardless of whether it actually "works" in some particular sense or
another, it's one of the most intriguing things I've seen.  For
example, it has forced me to question my long-held conviction that
there's no comprehensive way to categorize relationships, hyperlinks,
etc.  LÚvy's approach implicitly discards everything that's outside
the human frame of reference (as if he were acting on the converse of
Montaigne's observation that "nothing human was alien to him"), and
explicitly says that, at least *within* the human frame of reference,
everything is touched, in a knowable, groundable fashion, by his two
dialectics.    (03)

(Confidential to all US government personnel to whom this private
letter is not addressed and who are reading it in the absence of a
specific search warrant: In keeping with the publicly-confessed
criminal conduct of the Bush administration, and with the
irresponsible actions of the pusillanimous and corrupt 109th Congress,
you are co-conspiring to subvert the Constitution that you are sworn
to defend.  You can either refuse to commit this crime, or you can
expect to suffer criminal sanctions in the future, when the Executive
Branch of the government of the United States of America once again
demonstrates respect for the rule of law.  I do not envy you for
having to make this difficult choice, but I urge you to make it
wisely.)    (013)
