The Internet contains a vast trove of information — sometimes called the “Deep Web” — that isn’t indexed by search engines
What you see when you do a basic Web search is only the tip of the iceberg. The Internet contains a vast trove of information — sometimes called the “Deep Web” — that isn’t indexed by search engines: information that would be useful for tracking criminals, terrorist activities, sex trafficking and the spread of diseases. Scientists could also use it to search for images and data from spacecraft.
The Defense Advanced Research Projects Agency (DARPA) has been developing tools as part of its Memex program that access and catalog this mysterious online world. Researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, have joined the Memex effort to harness the benefits of deep Web searching for science. Memex could, for example, help catalog the vast amounts of data NASA spacecraft deliver on a daily basis.
“We’re developing next-generation search technologies that understand people, places, things and the connections between them,” said Chris Mattmann, principal investigator for JPL’s work on Memex.
