An example scenario in real-life would be crowdsourcing services like Amazon’s Mechanical Turk (MTurk). In the machine learning community, researchers use MTurk for manual data annotation or labeling for applications like behavior signal processing, computer vision and so on [10], [11], [12]. Here, annotators need to be ensured that they will receive a payment for their work, and researchers need to be ensured on the quality and correctness of these annotations, which is a challenging problem [12].
