摘　　要：针对网络舆论系统演化过程中选择何种导向方法的问题,通过社会网络分析(SNA)法研究网络中个体(A-gent)的点度中心度。设计了1种网络舆论导向的算法,对导向中常见的软控制与硬控制方法进行了定量分析。以天涯论坛上1个网络事件为实验数据,对导向算法进行了仿真验证,并深入分析了这种导向算法在舆论演化各个阶段的运用方法。该研究具有一定的理论指导意义与实际应用价值。To solve the problem of choosing guiding methods of the Internet public opinion in its evolvement,the point centrality based on SNA was studied.The arithmetic of guiding public opinion was designed,and the common methods of guiding public opinion in the Internet through the maximal point centrality in SNA were quantitatively analyzed.Using the data of an event occurred in Tianya forum,the method was simulated,and the advice was proposed to guide the Internet public opinion in all stages of its evolvement.
