摘要

Collaborative filtering is one of the most conventional algorithm in recommendation system. However, CF suffers from data sparsity and scalability issues. Thus, we propose Canopy–K-means Combined Collaborative Filtering (CK-ComCF) to solve the challenge of data sparsity and scalability. In particular, the prediction outcomes of user-based CF and item-based CF are integrated using a weighting appro...
