[目的/意义] 旨在通过对突发事件舆情研究，探索危机传播管理中的舆情研判方法，并进一步为政府信息公开提供实操方法的建议。[方法/过程] 在理论研究层面，基于危机传播的基本要点，对信息发布效果和舆情实时反馈进行综合分析；在应用处理层面，以新浪微博中“天津爆炸”事件相关信息为例，爬取新浪微博全量数据，基于危机传播领域知识和信息发布文本构建领域词表，并结合危机传播阶段特征，对全量数据进行主题提取和情感分析。[结果/结论] “后微博”时代，微博用户量下降，但其仍旧是突发事件信息公开和舆情扩散的主要阵地。探求突发事件下政府如何利用微博平台，收集、研判、应对网络舆情，为做好信息发布工作提供科学的分析方法和应对手段。
