Abstract: Methods and systems for result aggregation in crowdsourcing are described. In one implementation, a task with a plurality of solution options is provided for workers to respond. Responses for the task are received from multiple workers, where each of the responses includes a worker response confidence value corresponding to one of the plurality of solution options. The worker response confidence value is indicative of confidence of a worker for the one of the plurality of solution options to be correct. A task answer for the task is estimated based on at least the worker response confidence value received from each of the multiple workers. A performance bonus for each of the multiple workers is computed based on the task answer, the worker response confidence value in the response from each worker, and a Proper Scoring Rule.
