This document discusses the size and quality of information available on the "deep web" or non-searchable parts of the internet, as compared to the "surface web" or searchable parts. It finds that the deep web is about 500 times larger than the surface web, with documents in the deep web having an average quality score about 3 times higher per document. The total quality of information in the deep web vastly exceeds that of the surface web by thousands of times. The deep web has long been underestimated in size and importance, with some estimates placing it as large as the surface web or larger and growing exponentially.

stress, which results in the release of
Cortisol and adrenaline from the
adrenal glands. Initially, this cocktail
enhances memory. ... In small doses,
this can be useful, but habitually
using this kind of attention will
put people's ability to problem
solve and interact with others at
risk .”

turning the web into a massive garbage
dump, that many sites are simply replicating
the content of others like TechCrunch, and
that Google has no incentive to stop this
because it gains advertising revenue from the
spammers.”

8. Content creation is big business, and there are big players
involved. For example, Associated Content, which produces
10,000 new articles per month, was purchased by Yahoo! for
$100 million, in 2010. Demand Media has 8,000 writers who
produce 180,000 new articles each month. It generated more
than $200 million in revenue in 2009 and planning an initial
public offering valued at about $1.5 billion. This content is
what ends up as the landfill in the garbage websites that you
find all over the web. And these are the first links that show
up in your Google search results.

education is to create an educational system that
exploits the natural curiosity of children, so that
they maintain their motivation for learning not only
through their school years but throughout life. We
need to convince teachers and parents of the
importance of children's questions."

Deep Web vs. surface Web scores were obtained by using the BrightPlanet technology's selection by source option and then counting total
documents and documents above the quality scoring threshold.
Results and Discussion
This study is the first known quantification and characterization of the deep Web. Very little has been written or known of the deep Web.
Estimates of size and importance have been anecdotal at best and certainly underestimate scale. For example, Intelliseek's "invisible Web"
says that, "In our best estimates today, the valuable content housed within these databases and searchable sources is far bigger than the
800 million plus pages of the 'Visible Web.'" They also estimate total deep Web sources at about 50,000 or so. [35]
Ken Wiseman, who has written one of the most accessible discussions about the deep Web, intimates that it might be about equal in size to
the known Web. He also goes on to say, "I can safely predict that the invisible portion of the Web will continue to grow exponentially
before the tools to uncover the hidden Web are ready for general use." [36] A mid-1999 survey by About.com's Web search guide
concluded the size of the deep Web was "big and getting bigger." [37] A paper at a recent library science meeting suggested that only "a
relatively small fraction of the Web is accessible through search engines."[38]
The deep Web is about 500 times larger than the surface Web, with, on average, about three times higher quality based on our document
scoring methods on a per-document basis. On an absolute basis, total deep Web quality exceeds that of the surface Web by thousands of
times.
