From the article: "In the short video interview, Binney explained a bit more about the NSA spying on Americans: "Domestically, they're pulling together all the data about virtually every U.S. citizen in the country and assembling that information, building communities that you have relationships with, and knowledge about you; what your activities are; what you're doing. So the government is accumulating that kind of information about every individual person and it's a very dangerous process.""

I imagine this is where Palantir is being used. About building the connections through large data sets on the science of ontology.
