【目的/意义】微博的即时化和快速化等特点使得微博信息,特别是负面信息的传播速度和影响力大为增强,如何更好地管理舆情成为目前亟待解决的问题之一。【方法/过程】本文基于微博的情感特性和传播特性,构建微博舆论场能量模型,并以2015年的十大热点微博为例,分析微博传播特性、情感特性以及时间指数对微博舆情能量场的影响。【结果/结论】数值模拟结果显示,微博舆情情感值的绝对值越大,传播特性的指标越高,微博舆情的正向或负向能量峰值越大,同时微博出现二次峰值;另外时间指数越大,微博舆情的能量耗散越大,微博舆情能量值下降也越快。本文的研究将为网络舆情引导与管理提供重要参考。
[Purpose / Significance] The characteristics of instant and quick microblogging make the propagation speed and influence of Weibo information, especially negative information greatly enhanced. How to better manage public opinion has become one of the most urgent problems to be solved. 【Method / Process】 Based on the emotional and communication characteristics of Weibo, this paper constructs the energy model of Weibo media, and takes the top ten hot microblogs in 2015 as an example to analyze the diffusion characteristics, emotional characteristics and time index of Weibo, Bo influence of public opinion field of energy. [Results / Conclusion] The results of numerical simulation show that the greater the absolute value of the emotional value of microblogging, the higher the index of the propagation characteristics, the larger the positive or negative energy peak of the microblogging public opinion, and the second peak appears on the Weibo. In addition, the larger the time index, the greater the energy dissipation of microblogging public opinion, and the weaker the public opinion energy value of microblogging declines faster. The research of this article will provide important reference for guiding and managing internet public opinion.
