对网络传播机理建模是利用或控制网络传播的基础。为了模拟个体传播行为与系统状态演化之间存在的动力学关系,采用社会物理学研究思路,借鉴物理学振动传播的概念,定义了量化影响力的网站传播影响强度模型,通过量化网民与网站交互时,所感知局部环境信息对网民行为自适应性的综合影响力,来体现系统中各动力学因子的作用。在此基础上,结合基于Agent的方法对个体属性及交互规则进行描述,即可仿真动态环境作用下的微观个体行为与宏观系统演化之间的双向性关联。仿真模型的运行结果能很好的与实证研究相互印证,说明了该方法的可行性,为类似问题建模提供了一种新的思路。“,”Modeling the mechanism of information diffusion is the basis of network diffusion utilizing and controlling.For modeling the consequence between individual diffusion behavior and system state evolvement,and adopting the thinking in social physics,the site diffusion impact factors model was defined referencing to the description of the vibration state and process of particle under outside force.The synthesized dynamical impact from each dynamics factors of diffusion system to the adaptability behaviors was proposed with the sensed state information by interacting user.Combining this model with agent-based individual property and interact rules,a web information diffusion simulation model was built,and the bidirectional relation between microscopic individual behavior and macroscopic system evolvement under the influence of dynamic environment could be simulated.The simulation results are consistent with empirical results,which show the feasibility of the method.It is a new approach to model similar systems.
