From Big Data to relevant data

摘要

After multiple attacks on U.S. embassies in the 1990s, the FBI created an Investigative Services Division in 1999. Its focus was collating counterterrorism data. Staffed with a team of analysts, the division sorted through file after file searching for clues that could predict the next terrorist attack. Despite their efforts, the team couldn't possibly sort through every single file because one critical file that they missed was hidden on the first floor of FBI headquarters in a storage room and, therefore, was not considered. The file contained a 1998 report by an FBI pilot who had suspicions about Middle Eastern flight students in Oklahoma City. The report didn't make it into the new division's predictive assessments. How many more clues are hidden in filing cabinets, storage rooms or siloed systems waiting to be uncovered - or might be missed?
