A big problem in crowdsourcing markets is the design of robust quality assurance mechanisms. Today, the lack of methods is compensated using massive redundancy in task allocation and / or the use of voting mechanisms. Recenty research showed that the use of behavioral data (e.g., working time per task, mouse movements) can be a sophisticated indicator for the resulting quality.
In this bachelor / master thesis, you will design several worker behavior-based quality predictors and evaluate them in various domains.
