WHat DO YOU KNOW ABOUT THE "DEEP WEB"

If the most coveted commodity of the Information Age is indeed information, then the value of deep Web content is immeasurable. With this in mind, BrightPlanet has quantified the size and relevancy of the deep Web in a study based on data collected between March 13 and 30, 2000. Our key findings include:

* Public information on the deep Web is currently 400 to 550 times larger than the commonly defined World Wide Web.
* The deep Web contains 7,500 terabytes of information compared to nineteen terabytes of information in the surface Web.
* The deep Web contains nearly 550 billion individual documents compared to the one billion of the surface Web.
* More than 200,000 deep Web sites presently exist.
* Sixty of the largest deep-Web sites collectively contain about 750 terabytes of information -- sufficient by themselves to exceed the size of the surface Web forty times.
* On average, deep Web sites receive fifty per cent greater monthly traffic than surface sites and are more highly linked to than surface sites; however, the typical (median) deep Web site is not well known to the Internet-searching public.
* The deep Web is the largest growing category of new information on the Internet.
* Deep Web sites tend to be narrower, with deeper content, than conventional surface sites.
* Total quality content of the deep Web is 1,000 to 2,000 times greater than that of the surface Web.
* Deep Web content is highly relevant to every information need, market, and domain.
* More than half of the deep Web content resides in topic-specific databases.
* A full ninety-five per cent of the deep Web is publicly accessible information -- not subject to fees or subscriptions.

To put these findings in perspective, a study at the NEC Research Institute (1), published in Nature estimated that the search engines with the largest number of Web pages indexed (such as Google or Northern Light) each index no more than sixteen per cent of the surface Web. Since they are missing the deep Web when they use such search engines, Internet searchers are therefore searching only 0.03% -- or one in 3,000 -- of the pages available to them today. Clearly, simultaneous searching of multiple surface and deep Web sources is necessary when comprehensive information retrieval is needed.

Why are there no "adult" sites on CompletePlanet?

Our focus is to provide the most comprehensive access point to
searchable sites on the Web for the research and "power user"
community needing sophisticated information and content access. We do
not see "adult" sites as consistent with that mission.

I think you've been dissed, BVT.

Don't you mean you hoped it could, as opposed to being concerned that it could, Bear?

Im beginning to think that its not a place but merely a format. Ive used the access provided by the SUNY site and was able to uncork some tables of seismic data. Many times a report by an agency or a research institution , will have appendices and have forays into the unpublished "gray" literature. So , I think the term "deep web" just allows a user to access the original data if its in pdf that would otherwise be in a series of appendices.

what would possibly give you that idea? :wink:
