As a novel method for alleviating the sparsity problem in collaborative filtering (CF), we explore crowdsourcing-based CF, namely CrowdCF, which solicits new ratings from the crowd. We study three key questions that need to be addressed to effectively utilize CrowdCF: (1) how to select items to show for crowd workers to elicit extra ratings, (2) how to decide the minimum quantity asked to the c...

The current paper introduces a receiver-operating characteristic (ROC)-based methodology to establish meaningful cut points for the VisAWI (visual aesthetics of websites ...
