[Purpose/significance]This paper aims to improve the accuracy, effectiveness and efficiency of public opinion strategies by mining universal characteristics and laws of transmission paths on public opinion hidden in the massive data.[Method/process]From the perspective of information diffusion effect, this paper proposes a WSD-Rank influential evaluation model by taking an overall consideration of transmission width, speed and depth. Based on the measurement of individual influence, it explores the structural characteristics and evolutional laws of the public opinion transmission model according to the extended structure of information diffusion.[Result/conclusion]The results show that: public opinion transmission presents various diffusion models; different diffusion models have distinct on the transmission coverage, transmission speed, transmission efficiency and transmission life cycle; there are interactive evolution and intersection among diffusion models.
