It is demonstrated that these ranking prediction approaches can get better ranking results than rating prediction ones. However, experiments show that good performance on ranking prediction does not necessarily indicate good quality of top-N recommendation, which is the main purpose of recommender systems. 3 X. Zhao et al. Two-Step Recommendation Approaches Typical recommendation task is based on the rating data which contain two layers of user behaviors. The first one is that the current user selects an item to rate.

Since our proposed method, denoted as HNFR, combines all the explicit features (social features and event-based features) and latent features, we devise methods that incorporate these factors individually. Beside, we compare our method with some existing works which are designed for followee recommendation in traditional social networks. In summary, we compare HNFR with the following methods: – FoF [5]: For each user u, this method ranks the candidates according to the number of user u’s followees who have followed the candidate.
