Collaborative filtering (CF) has been widely used and successfully applied to recommend items in practical applications. However, the collaborative filtering has two inherent problems: data sparseness and the cold-start problems. In this paper, we propose a method of integrating additional feature information of users and items into CF to overcome those difficulties and improve the accuracy of recommendation. We apply a two-pass method, first filling in unknown preference values, then generating the top-N recommendations. © Springer-Verlag Berlin Heidelberg 2004.
