Declassification Engine: A Program That Analyzes What The Government Keeps Secret And Why

At Columbia University in New York, a historian named Mathew Connelly is working with computer scientists and statisticians on a “declassification engine.” It’s a project that will not just archive millions of declassified government documents, but also mine them for hidden patterns that reveal what the US government chooses to keep secret and why. This story was featured in the pilot episode of the new public radio series focusing on investigative journalism called "Reveal."
