| [ 目的/ 意义] 探究影响网络舆情反转的因素能够对于网络舆情事件发展有更深层次的理解，避免或减少发生舆论反转事件，促进社会和谐。[ 方法/ 过程] 根据新闻传播主体“三元”类型结构，选取“菲妥妥- 穆修修”事件当事人、主流媒体的微博及网民评论，基于BiLSTM-Attention 模型对网民情感分类，划分舆情发展的阶段。以情感分类和关键词提取的方式对舆情发展过程中情感极性变化以及当事人回应、主流媒体及微博大V 的发声对网民情感的影响进行动态分析，再选取“三元”传播主体均发挥作用的“双黄连抑制新冠病毒”事件与“菲妥妥”事件进行对比，进一步分析当事人回应、主流媒体及微博大V 在舆情发展中的作用。[ 结果/ 结论] 由结果可知，网络舆论事件中，“三元”主体应当是平衡的，主流媒体的缺失会直接导致微博舆情反转。 |
