New Research Engine Searches “Deep Web”
How much of the World Wide Web is actually indexed… 27.65 billion pages? Maybe about 0.2% of the total content? The “Deep Web” (web documents not immediately accessible by direct hyperlink from public pages) may contain something like 91,000 terabytes of data… as compared to an estimated 167 terabytes of Surface Web data.
A new service, called Infovell, hopes to help users find more of this “Deep Web” data… yet unlike Google and other Surface Web engines, it won’t be ad-supported. Instead, the service will be subscription based. Read more at ReadWriteWeb blog. Here is an excerpt from the article:
The engine scours through open-access repositories of information like PubMed Central and the U.S. Patent and Trademark Office Claims, but it also allows access to scholarly journals such as those from Oxford University Press, SAGE, Taylor & Francis, Annual Reviews, Mary Ann Liebert Publications, and more. The culmination of these billions of pages currently unindexed by other engines, gives you access to content in the areas of Life Sciences, Medicines, Patents, Industry News, and other reference content from expert sources.

Deep Web Technologies has been searching “deep web” sources for close to 10 years and has created several search engines that are publicly available on the internet. Here are a few sci-tech resources:
http://www.science.gov- This source searches over 200 million pages of information from authoritative sources like PubMed, ERIC, USPTO, NASA, Agricola, and EPA to name just a few.
http://www.scitopia.org- This free search delves into 21 sci-tech societies (like IEEE and SPIE) and 3 patent offices.
http://multisearch.dtic.mil/dtic/- This is a comprehensive search of federal scientific and technical information through the defense community which also searches scitopia.org, science.gov, and worldwidescience.org.
http://www.worldwidescience.org- A free science research site federating scientific and technical information from over 30 countries.
http://www.biznar.com- A free search of credible business sources done in real time. Features include- ability to choose your own sources, alerts, clustering, sort options, refine search. This is an excellent basic research source which also includes patent offices and news sources.
All of these search engines are completely free to use and require no subscription unless the researcher is using the automatic alerts or RSS feed capability. These engines were created by Deep Web Technologies, aptly named for our ability to create “deep web” search engines.
