I've written about applying big data as a solution to human trafficking a few years ago, but what was available then still relied on people calling in.
Now there's a more advanced solution:
"The tool, called DIG (for “Domain-specific Insight Graphs”), allows officers who are searching for a missing child who is believed to be trapped in the escort industry to search by phone number, location, alias—even by photo—and pin down a way to reach them.
“The internet contains seemingly limitless information, but we’re constrained by our ability to search that information and come up with meaningful results. DIG solves that problem,” says Szekely, research associate professor at ISI.
DIG is simple enough that it won’t require special training to use. The database it utilizes currently has 50 million web pages, 2 billion records, and grows at a rate of roughly 5,000 web pages per hour.
“As the database continues to grow, DIG will be able to uncover new connections and patterns in the data, making it even more useful,” says Knoblock,"
