摘要
对突发事件网络舆情的传播模式加以分析,对舆情演变的每一个阶段的特点和表现形式,通过建立logistic回归模型并求解。针对突发公共事件网络舆情每个演变阶段的特征和作用因素提出合理化建议。基于以上分析和研究,通过实际案例对模型有效性进行验证,以百度指数的搜索数据为基础,用51组数据拟合模型,通过不一致系数来判断拟合效果,证明了方法的有效性和准确性。
This study analyzes the communication mode of online public opinion of emergency,and solves the feature and patterns of expression on each phase of its evolution with the logistic regression model.Reasonable suggestions are put forward aiming at the characteristics and factors of evolution of online public opinion of emergencies.Based on the above analysis and research,the validity of the model is verified through practical cases.With the search data of Baidu index,the model is fitted with 51 sets of data and the fitting effect is judged by the inconsistency coefficient,which proves the validity and accuracy of the method.
