摘要
针对目前定量观测、分析和控制突发网络舆情研究中的困难,在定性分析用户关系网络的基础上,研究并选取一系列可定量度量舆情传播行为的指标,给出各指标的选取依据和计算方式。通过试验评估了各指标的有效性,发现在网络中用户数变化各定量指标产生了明显的变化,这种变化可以在不同程度和层次上反应网络舆情的变化。
Currently it is difficult to quantitatively observe,analyze and control Emergent Internet Public Opinion （IPO）. On the basis of analysis of user network relationship ,a series of quantitative metrics are selected to describe the propagation of Internet Public Opinion. Their selection reasons and computing method are explained in details. The validity of quantitative metrics is proved by experiments. According to the quantitative analysis metrics change apparently when the number of users change and these changes may reflect the changes of Internet Public Opinion in different degrees and levels.
