[Corpora-List] Bootcamp: 'Quantitative Corpus Linguistics withR'--re Louw's endorsement

[Linas Vepstas]

Hi Wolfgang,

Marvelous reply! I enjoyed reading it, and so can hardly
let the conversation slide by failing to respond. I fear
I am too sophmoric in my reply, but I try.

There have been many acts of what I call primordial speech situations in which chairs and tables have been pointed out to me. For me, such things are props that make up an extension of the speech situation. The act of ostentation make them part of the communication. If I had a dog it wouldn't know what a chair is. It would not even have noticed it had been part of such a speech situation. I recall discussions with people (not with dogs, though) in which we attempted, for instance, to negotiate if barstools with a back rest should be referred to as stools ("Could you bring two more stools over, please?"). Does the result of such speech situations and negotiations mould my mental concept? I think it does. Does each of us have the same (perhaps innate) concept of a chair (as Fodor sees it)? Rather unlikely. Does everybody have their individual concepts? If yes, how do we understand each other, except by assuming that meaning is in the discourse and not in our heads?

I really like the notion of language as being negotiated, as it
does anchor many difficult linguistic phenomena. So, yes,
"chairs" don't exist for dogs, because they do not participate
in human language.  But this does beg the question: might
not some dogs have a mental concept of something, which,
if they could only talk, they might call a "chair"?  There are
any number of dog-as-hero stories, where the dog brings the
right item, performs the right action, for a given situation,
which would lead one to conclude that dogs can make
appropriate conceptual abstractions.  Even more amazing
is the recent research on tool-use in crows. We have no hope
of teaching human language to a crow, and yet, one would
have an extremely difficult time of arguing that crows do not
possess the abstract notion of what we would call "a tool".

As a guiding principle for linguistics, it seems very correct to
state that nothing exists outside of the corpus.  Yet, one must
not err into a debate as to whether qualia exist (qualia being,
by definition, private, personal, incommunicable, "ineffable").
So: "my foot hurts" -- you cannot ever truly feel my pain.
Language, the corpus, communicates the general notions
of "foot" and "hurts", so that, one day, when your foot hurts,
you'll be able to reflect, and think "this part of my body,
we call it 'a foot', and this foot of mine, its emanating a
sensation which we've negotiated a term for: it is 'pain".
I'd argue that qualia exist.

I'm of the opinion that the sensation itself is ineffable --
indescribable, although real.  Now, as to "the catch"
in rowing: -- is it like a foot that hurts, unknowable till
you actually experience it?  My original intent was to
say "yes, of course it is" -- authors and coaches
have attempted to wrap words around it, with varying
success, but there remains a body-sensation that
remains apart from those words (and motivates the
creation of those words).

There are factions in cognitive linguistics which argue
that, ultimately, one cannot create a "talking machine"
(AI) that correctly manipulates concepts linguistically,
without also endowing that machine with senses. So,
yes, corpus linguistics and cognitive linguistics are
irreconcilable, at this level. But these same factions
also make a claim that there are ways of uniting
"rules", "predicates", "logics" (first-order logic,
non-axiomatic logic) with probabilities (Markov chains)
in such a way that these probabilistic logic networks
can be used to learn and capture lexical items (by
working from a corpus) *as well as*, with no alteration
of the theory, learn and capture sensorimotor sensations.
And so, at this deeper level, the claim is that cognitive
and corpus linguistics can be reconciled, although one
has to be abstract in doing so.

(To be specific: someone pointed to Susan Atkin's
"Lexical Implication Rules" -- the goal is to have a
machine automatically learn and deduce these;
the presumption is that proabilistic logic can be
used to learn these from a corpus, and that, once
learned, these can be employed in some useful
fashion in some other part of the system. No one
has done so yet, and is unlikely to do so soon, but
there is the general sense that this kind of stuff is
not out of reach. Only time will tell what the reach
will be.)
