Recommender system using DSmTrust trust model
Jin Wang · Computer Engineering and Applications Journal · 2011
Collaborative filtering is the main recommendation technology,which suffers from sparsity and scalability problems.A recommender system based on DSmTrust trust model is proposed.The trust transitivity is employed to overcome the sparsi-ty problem and the distributed DSmTrust approach has good scalability.Experiments show that this study has better coveragethan collaborative filtering and has higher accuracy than Massa's trust-aware recommendation approach.
