| 摘 要： | 本文首先介绍了信号分析的理论与方法,并把基于信号分析的突发事件网络舆情预警分为两个维度：信号纵向挖掘和信号横向防控。其次在两个维度中分别尝试提出了分析模型,并详细描述了分析步骤。最后总结了信号分析应用于突发事件网络舆情预警的优点。Abstract：This paper firstly introduces the theory and method of signal analysis,then divides the early warning of network opinion on emergencies based on signal analysis into two dimensions：vertical signal mining and horizontal signal control.The paper tries to propose an analytical model for each dimension separately,and describes the analytical approaches in detail.Finally,the advantages of applying signal analysis in early warning of network opinion on emergencies are summarized.
