摘要：Singular Value Decomposition (SVD) is a trust-based matrix factorization technique for recommendations is proposed. Trust SVD integrates multiple information sources into the recommendation model to reduce the data sparsity and cold start problems and their deterioration of recommendation performance. An analysis of social trust data from four real-world data sets suggests that both the explicit and the implicit influence of both ratings and trust should be taken into consideration in a recommendation model. Trust SVD therefore builds on top of a state-of-the-art recommendation algorithm, SVD++ uses the explicit and implicit influence of rated items, by further incorporating both the explicit and implicit influence of trusted and trusting users on the guess of items for an active user. The proposed technique extends SVD++ with social trust information. Experimental results on the four data sets demonstrate that Trust SVD achieves accuracy than other recommendation techniques.
