. . . . "The Find-Fix-Verify pattern [3] consists on dividing a complex human task into a series of simpler tasks that are carried out in a three-stage process. Each stage in the Find-Fix-Verify pattern corresponds to a verifi- cation step over the outcome produced in the immediate previous stage. The first stage of this crowdsourcing pattern, Find, asks the crowd to identify portions of data that require attention depending on the task to be solved. In the second stage, Fix, the crowd corrects the elements belonging to the outcome of the previous stage. The Verify stage corresponds to a final quality control iteration." . . . .
