ABSTRACT
Berners-Lee's vision of the Semantic Web is
hindered by a chicken-and-egg problem, which
can be best solved by a bootstrapping method:
creating enough structured data to motivate
the development of applications. We believe
that autonomously `Semantifying Wikipedia' is
the best way to bootstrap. We choose
Wikipedia as an initial data source, because
it is comprehensive, high-quality, modestly
sized, and contains enough manually-derived
structure to bootstrap an autonomous,
self-supervised process. In this talk I will
present our success to date in this endeavor:
A novel approach for self-supervised
learning of CRF information extractors
Automatic construction of a comprehensive
ontology via statistical-relational learning
Vast improvements in extraction recall
through shrinkage over this ontology and
retraining
The stimulation of a virtuous feedback cycle
between communal content creation and
information extraction
We aim to construct a knowledge base of
outstanding size to support inference,
automatic question answering, faceted
browsing, and potentially to bootstrap the
Semantic Web.

Brion Vibber
Brion Vibber has worked on MediaWiki and
Wikipedia's servers for four years, watching
over its frightening growth from thousands to
millions of pages, from dozens to thousands
of hits per second.
ABSTRACT
Over four years, MediaWiki has evolved from a
quick hack to run a little-known encyclopedia
web site to the monster engine behind a
heavily-used public site, while maintaining
the simplicity needed for an entry-level
intranet wiki. Brion reviews past and future
directions for Wikipedia's software and
hardware, and how modern buzzword
technologies could power and simplify the
wiki world.

The Truth according to Wikipedia
More info on

eringen/39405191/ (Dutch)
Google or Wikipedia? Those of us who search
online -- and who doesn't? -- are getting
referred more and more to Wikipedia. For the
past two years, this free online
"encyclopedia of the people" has been topping
the lists of the world's most popular
websites. But do we really know what we're
using? Backlight plunges into the story
behind Wikipedia and explores the wonderful
world of Web 2.0. Is it a revolution, or pure
hype?
Director IJsbrand van Veelen goes looking for
the truth behind Wikipedia. Only five people
are employed by the company, and all its
activities are financed by donations and
subsidies. The online encyclopedia that
everyone can contribute to and revise is now
even bigger than the illustrious Encyclopedia
Britannica.
Does this spell the end for traditional
institutions of knowledge such as Britannica?
And should we applaud this development as
progress or mourn it as a loss? How reliable
is Wikipedia? Do "the people" really hold the
lease on wisdom? And since when do we believe
that information should be free for all?
In this film, "Wikipedians," the folks who
spend their days writing and editing
articles, explain how the online encyclopedia
works. In addition, the parties involved
discuss Wikipedia's ethics and quality of
content. It quickly becomes clear that there
are camps of both believers and critics.
Wiki's Truth introduces us to the main
players in the debate: Jimmy Wales (founder
and head Wikipedian), Larry Sanger
(co-founder of Wikipedia, now head of Wiki
spin-off Citizendium), Andrew Keen (author of
The Cult of the Amateur: How Today's Internet
Is Killing Our Culture and Assaulting Our
Economy), Phoebe Ayers (a Wikipedian in
California), Ndesanjo Macha (Swahili
Wikipedia, digital activist), Tim O'Reilly
(CEO of O'Reilly Media, the "inventor" of Web
2.0), Charles Leadbeater (philosopher and
author of We Think, about crowdsourcing), and
Robert McHenry (former editor-in-chief of
Encyclopedia Britannica). Opening is a video
by Chris Pirillo.
The questions surrounding Wikipedia lead to a
bigger discussion of Web 2.0, a phenomenon in
which the user determines the content.
Examples include YouTube, MySpace, Facebook,
and Wikipedia. These sites would appear to
provide new freedom and opportunities for
undiscovered talent and unheard voices, but
just where does the boundary lie between
expert and amateur? Who will survive
according to the laws of this new "digital
Darwinism"? Are equality and truth really
reconcilable ideals? And most importantly,
has the Internet brought us wisdom and truth,
or is it high time for a cultural
counterrevolution?

Google Tech Talks
June 14, 2008
ABSTRACT
IGlobal online services at Amazon, eBay,
Myspace, YouTube, or Google serve millions of
customers with tens of thousands of servers
located throughout the world. At this scale,
components fail continuously and it is
difficult to maintain a consistent state
while hiding failures from the application.
Peer-to-peer protocols provide availability
by replicating services among peers, but they
are mostly limited to write-once/read-many
data sharing. To extend them beyond the
typical file sharing, the support of fast
transactions on distributed hash tables
(DHTs) is an important yet missing feature.
We will present a distributed key/value store
based on a DHT that supports consistent
writes. Our system comprises three layers:
- a DHT layer for scalable, reliable access
to replicated data,
- a transaction layer to ensure data
consistency in the face of concurrent write
operations,
- an application layer with an extremely high
access rate.
For the application layer, we selected a
distributed, scalable Wiki with full
transaction support. We will show that our
Wiki outperforms the public Wikipedia in
terms of served page requests per second and
we will discuss how the development of the
distributed code benefited from the use of
Erlang.
This is joint work of Zuse Institute Berlin
and onScale solutions GmbH.
Speaker: Thorsten Schuett, Zuse Institute
Berlin
Thorsten Schütt is a senior researcher with
the Zuse Institute Berlin (ZIB) and a
co-founder of onScale solutions GmbH. He
received a CS diploma with distinction in
2002 from the Technical University Berlin.
Since then he works as a research staff
member in the Computer Science Research
Department at ZIB and participates in several
EU projects like GridLab, XtreemOS and
Selfman. He is the principal system architect
of the scalable, transactional key/value
store at ZIB. His research interests include
distributed data management, scalable grid
systems, p2p algorithms and self-managing
transactional
storage systems.

http://www.ted.com Jimmy Wales recalls how he
assembled "a ragtag band of volunteers," gave
them tools for collaborating and created
Wikipedia, the self-organizing,
self-correcting, never-finished online
encyclopedia.

| Tom Lehrer - Who's Next (old Wikipedia version) |
 |
Tom Lehrer on Amazon.com:
http://www.amazon.com/Tom-Lehrer/e/B000AQ1ECM
/ref=ntt_dp_mus_hqp
The channel now has a NEW version of this
song with Tom Lehrer's verbal intro and no
Wikipedia quotes. Visit the channel's front
page. This version is the earliest posted
version from 2007.
"Who's Next" is unfortunately still a hot
topic today. Iran will maybe have the bomb
ready before South Africa? The Wikipedia list
of states with nuclear weapons will no doubt
continue to grow.
Lehrer said "OK" to "The Tom Lehrer wisdom
channel" on YouTube, as long as the
performance is not altered and as long as
it's free in the YouTube flash video format.
Do NOT ask for any video originals, ever
again.
