How much of the data sold to the CIA/NSA is from public resources?
Of the sort you find at Knoema?
Albeit some of it isn’t easy to find but it is public data.
A topic map of public data resources would be a good CIA/NSA Diff Utility so they could avoid paying for data that is freely available on the WWW.
I suppose the fall back position of suppliers would be their “value add.”
With public data sets, the CIA/NSA could put that “value add” to the test. Along the lines of the Netflix competition.
Even if the results weren’t the goal, it would be a good way to discover new techniques and/or analysts.
How would you “diff” public data from that being supplied by a contractor?
