Semantic Web for Navy Information Dominance Operations?

The information requirements for the Information Dominance Corps, which combines the Navy's
intelligence and information technology capabilities, will create an unprecedented increase in the demand for information services:
  1. Navy forces will  be connected into a single, global network for afloat, ashore and space.
  2. Every Navy platform will function as a data collector.
  3. Every data collector will make information available, in real time, for use by all other nodes.
  4. Every sensor will be connected via standard interfaces to make local data globally accessible.
  5. Every shooter will have the capacity to compile, assess and exploit data from any sensor or data repository.
  6. All data is will be universally discoverable, accessible and secure.
Translating these requirements into an operating environment will:
  1. Require every Navy sensor to be interconnected (such as radar, UAVs, intelligence sources, satellites, and observation sources). The estimated number of such sensors is at least 10,000.
  2. Generate, on the average, at least ten transaction/minute, which suggests at least six million transactions/hour.
  3. Retrieve and store electrical signatures, text and video with an average of at least 2 Megabytes per transaction. This would generate a stream of data totaling of at least 12 thousand terabytes/hour, or 300 petabytes/day.  At present (2009), Google processes about 25 petabytes/day. With the cost/petabyte declining 25-30% year (a 30 fold decline over ten years) one can project Google-like systems operating well in excess of the range projected for the Navy.
  4. Display to at least 50,000 shooters simple graphic displays extracted from the shared global files. Such data extraction would require a latency of not more than a quarter of a second, while assuring 100% network reliability achieved through multiple redundancies of data centers and communications links.
    To link the shooters to the data cannot use Google like key-word extraction methods. Only a semantic web, in which the computer network relates the relevance of data to a shooter's local situation can deliver what is necessary for meeting information dominance requirements.

    The deluge of video data from these unmanned aerial vehicles, or UAVs, is likely to get worse. By next year, a single new Reaper drone will record 10 video feeds at once, and the Air Force plans to eventually upgrade that number to 65. Chief of the Intelligence, Surveillance and Reconnaissance Division of the U.S. National Geospatial-Intelligence Agency, projects that it would take an untenable 16 000 analysts to study the video footage from UAVs and other airborne surveillance systems. (http://spectrum.ieee.org/robotics/military-robots/the-uav-data-glut).

    The semantic web makes it possible for computers to understand what can be extracted from huge files in the context of a shooter's unique inquiry. The key to such a capability is the availability of machine-readable metadata that provide the logical tags for connecting  related information. This makes it possible for automated agents to search and then display information from globally distributed databases.

    SUMMARY

    The stated Navy Information Dominance vision calls for the delivery of the most ambitious operational concepts ever conceived, anywhere. None of the existing commercial designs, such as Google, are comparable in scope.

    The systems planners for the Information Dominance capabilities should now consider proceeding with cloud designs that will function according to the stated vision.

    Starting with virtual servers, virtual desktops, data virtualization and network virtualization will place the Navy on a path that may take at least a decade to achieve.

    1. You really make it seem so easy with your presentation but I find this matter to be actually something which I think I would
      never understand. It seems too complicated and extremely broad for me.
      I am looking forward for your next post, I'll try to get the hang of it!
