ProPublica: Reporting Recipe: Using Amazon’s Mechanical Turk for Data Projects

Amanda Michel: "we began experimenting with mTurk last spring to clean, de-duplicate and reformat data. We’ve since used the tool to collect or proof more than 28,000 data points, from the names of companies that received stimulus money [6] to the categorization of answers to our home loan modification questionnaire [7]. We’re impressed with the speed and accuracy of its results. For example, a project we estimated would take a full-time staffer almost three days to finish was completed on mTurk overnight for $37, with 99 percent accuracy."
