The winning team will be rewarded $500 of credit on the Crowdflower platform. It is strongly encouraged (bordering on peer pressure) that this is used to create a dataset for the next Crowdflower research competition on Kaggle.  We hope that this initiative can generate great problems and new datasets for everyone to enjoy.
If the winning team is not interested in creating/labeling a dataset, we will continue to offer the prize to the highest team that is interested.
