Data Quality Guarantee Mechanism Based on Sunk Cost Effect.

To improve the data quality problem caused by the task location, a data quality guarantee mechanism based on sunk cost effect (DQSC) is proposed. Motivating participants to improve the quality of tasks, the psychological losses of participants whose tasks do not meet the standards is amplified by the sunk cost formed when task participants go to non-popular areas The effectiveness of the mechanism is verified by simulation experiments.
