The new algorithm firstly constructed two directed connection graphs based on user interactions and blog contents respectively, where nodes represented users and arcs embodied the direction relationship between users. Authority and hub of these two connected graphs was computed. The fusion authority was adopted as measurement to evaluate user's credibility. The data collected from Sina-Microblog as test set was used to conduct experiments. Threshold of credibility was obtained by repeated training, and then credibility curves of different algorithms were drawn to verify the feasibility and effectiveness of the new algorithm.
