Modeling of information diffusion based on network dimension-force

Before modeling basic hypotheses were determined firstly according to realistic status of network information diffusion. Then based on above hypotheses the mode of network information diffusion was analyzed, including its information amount, which provided the quantitative basis to describe the effect of network dimension-force. Then the cycle of network information diffusion was analyzed, and emphasis was put on cycle structure, information attainable stage, information adoptable stage and information secondary transfer stage. On that basis, we determined the principle and method of using the D-value (difference value) of diffusion stage to describe the effect of network dimension-force, and established network information diffusion model. Simulation was performed with practical data, and confirmed the effectiveness of the established model.
