But I am not presenting this as the ultimate question and answer
machine. Far from it. I am posing it as a showcase NLP aiding SPARQL
generation. (02)

See my comments above. (04)
Google, Bing, and others are silos. I am in the business of silo-busting
via Web architecture and open standards. I am most interested in a
global distributed database (offering equal billing to extensional and
intensional functionality) where hyperlinks are super keys that resolve
to entity relationship graphs endowed with machine and human
comprehensible entity relationship semantics.

Yes, but you continue to present examples that really aren't aligned to
my core point. Again, Google, Bing etc.. are all silos. Being a
corporation doesn't mean they have to be data silo vectors. They will
ultimately be far more successful once they understand the virtues of
de-silo-fication, at Web-scale. (06)

Resource riches don't matter so much on the Web. Google didn't even
exist 20 years ago. Imagine if someone told a VC (circa. 1992) that
Google and others would emerge in the future, at the expense of
Microsoft? 99.99% of the time you would have been laughed out of the room. (08)
The Web inflection is still very much in its infancy.

They don't really matter as much as you assume. They aren't the beacons
of measurement in this realms. (010)
They only become interesting whenever they plug into the global Web DBMS
and start publishing hyperlink based super keys. Whenever the come to
that reality, SPARQL's utility will be crystal clear to them.

The are increasingly being fused. There are many collaborations in the
Linked Data realm that leverage NLP services. I've been involved with
several (and counting) with lots of simple live demonstrations in hand
[1][2][3]. (012)

I want links to existing live systems based on SQL that can deliver
heterogeneous access to disparate Web accessible data sources via
hyperlink based super keys. Where are those systems? They don't exist
for a very good reason: they can't handle the nature of the Web: (014)
1. Unpredicatable query request volume
2. Unpredicatable query request scope
3. Unpredictable query results sets navigation across entity
relationship dimensions via cursors (static, keyset, dynamic, or mixed)
4. Unpredictable attention span of users . (015)
There is a showdown point on the horizon that will ultimately bring 1-4
in scope re. the likes of Google, Bing, and any other data silo player.

Not my point. See my comments above. It's all about data virtualization
via hyperlink based super keys.

Somewhat inaccurate, they contributed to the development of SPARQL. (020)
SPARQL is SQL for the new Web-scale DBMS frontier. It's extremely
powerful and utterly useful :-) (021)
