Additional comments

The paper is well written, and it has the potential to change the way temporal drifting and sparsed datasets are treated. The authors have developed a method to apply a Latent-based Temporal Optimization (LTO) approach to improve the prediction accuracy of CF by learning the past attitudes of users and their interests over time. The methodology part is well explained. However, few issues are raised.
- the results need to be improved. The reasons behind each finding should be explained by the support of previous related studies or authors' justifications.
- there exist some typo errors in figures 9 and 10. Specifically, in fig 9, the label font type is not consistent with the ones used in other figures. Also, no scaling is provided at the horizontal axis. The authors may need to scale the axes appropriately. While in fig 10, the horizontal axis title is not very clear.
