Abstract: Users’ subjectivities affect the objectivity and validity of reputation system. In this paper, an approach for eliminating differences of evaluation subjectivity is proposed by using harmonic mean and trust translation. Then, a dynamic reputation management model is also established. Finally, we run experiments to compare our subjectivity-eliminated reputation computation method and the unmodified method. The experimental results show that our method indeed improves the accuracy of reputation value.
