In his study “ Crowd production of training data , published by the Hans Böckler Foundation, Professor Dr. Florian Alexander Schmidt from the Dresden University of Applied Sciences reports that the quality requirements for the data - and thus also for the crowdworkers - are high. This has resulted in the establishment of specialized platforms that offer higher pay and better working conditions than many other crowdworking platforms. These include, for example, Mighty AI and Playment . Crowdworkers from Europe or the USA nevertheless currently tend to lose out because of the many qualified people from Venezuela who offer their work at a lower rate. The global labor market is subject to major fluctuations.

Generating training data also plays an important role in other industrial sectors. The Clickworker crowdworking platform cites applications such as voice recordings for machine learning of speech recognition systems or photos of faces and facial expressions for identifying moods.
