Abstract

As e-commerce continues to emerge in recent years, online stores compete intensely to improve the quality of recommender systems. However, most existing recommender systems failed to consider both long-term and short-term preferences of users based on purchase behavior patterns, ignoring the fact that requirements of users are dynamic. To this end, we present TUP-RS (Temporal User Profile based Recommender System) in this paper. Specifically, the contributions of this paper are two folds: (i) the long-term and short-term preferences from the topic model are combined to construct the temporal user profiles; (ii) the co-training method which shares the parameters in the same feature space is employed to increase the accuracy. We study a subset of data from Amazon and demonstrate that TUP-RS outperforms state-of-the-art methods. Moreover, our recommendation lists are time-sensitive.
