摘要
针对目前网络舆情热度研究工作的不足,提出了一个基于因果回路图的舆情热度演化模型。该模型引入了网民、媒体、政府三个宏观因素,描述了对舆情热度演化的影响。分析仿真实验表明,网民和媒体作用量对舆情热度产生了正向的影响,政府作用量导致了舆情的负向作用。该模型能够准确描述舆情热度的演化行为,为舆情研究提供基础。
As the research on hot degree of public opinion is immature,this paper proposes the discrete evolutionary model based on the causality loop diagram.The factor of Internet users,media and government are introduced into this model.Also the impact of these parameters on the evolutionary mechanism over pub-lic opinion′s hot degree is described.The analysis and simulation indicate that Internet users and media make the positive influence on the hot degree of public opinion and government makes the negative ones.This model can more accurately describe the evolutionary behavior of the public opinion,and provides a founda-tion for public opinion researches.
