摘要

Collaborative filtering, an effective classification of recommendation algorithm, now has included a lot of great algorithms. As one of them, Slope One is easy to implement and has wonderful recommendation result. This paper adds the time attribute of users and items into Slope One algorithm, presenting an improvement of the algorithm which is based on time optimization. With the experiments on Mahout, the better recommendation can be achieved through the proposed algorithm.
