The United States space agency the National Aeronautics and Space Administration's (NASA) Jet Propulsion Laboratory has joined Memex 'deep Web' search project of the Defense Advanced Research Projects Agency (DARPA).

The project was announced by DARPA, the agency of the US Department of Defense, last year. According to the agency, the project has been designed to overcome the limitations of traditional Web search. The participation of NASA's Jet Propulsion Laboratory has been confirmed by the research and development center's Chris Mattmann. According to Mattmann, the center wants technologies that could understand humans, things, places and link between them.

The reason for the center's participation in the project is to harness the advantages of deep Web searching for science. According to the Jet Propulsion Laboratory, the project could provide help in cataloging the huge amount of data that spacecraft of the space agency deliver every day.

Memex is not just able to standard text-based content online but also to standard pictures, videos, forms, scripts and a number of ways that store information. Mattmann said, "We're augmenting Web crawlers to behave like browsers - in other words, executing scripts and reading ads in ways that you would when you usually go online. This information is normally not cataloged by search engines".

According to reports, Memex is capable of identifying what is in the content. It pairs the content with searches on the same subject. It can also recognize the same object in a number of frames of a video. This quality of Memex could provide help NASA's future space missions that capture pictures and videos. As per scientists, searching visual information about a planetary object could make things easy for scientists analyzing geological features.

JPL said that Memex is a boon for scientists as it can collect useful data from the PDF prison.
