Abstract
We posit that trustors who follow the same trustee have features in common. Based on the assumption that trustors who endorse the same trustee share similar tastes, we propose a new latent feature called Matrix S, and develop two novel RS algorithms that learn these latent features. We conduct an extensive performance evaluation using large scale real-world datasets, and observe that our proposed methods are not only more accurate than existing schemes but also show potential extensibility.
