【Abstract】This study compares two popular selection mechanisms in crowdsourcing contests for creative works: expert rating and crowd voting. We systematically study their differences in terms of winner determination and effects on participation. We find that expert rating and crowd voting are quite different. In terms of winner determination, crowd voting strongly favors early entry and contestants with a high level of social engagement, but neither is true for expert rating. Moreover, past performance in crowd voting predicts future success in crowd voting but not expert rating, and vice versa. In terms of participation, we find that a high ratio of crowd prizes appeals contestants with little submission experience or high performance in crowd voting, and the overall participation increases with the ratio of crowd prizes.
