摘要本研究提出一种从突发公共卫生事件的舆情信息中提取群体智慧的方法，揭示了突发公共卫生事件舆情环境下群体智慧涌现的模式与规律。以群体免疫相关话题为例，利用依存分析的关系抽取（relation extraction with dependency parsing，REDP）方法提取微博、评论含有的三元组，以结构化表示突发公共卫生事件舆情环境下公众的知识条目，基于舆情知识三元组、网络拓扑结构挖掘突发公共卫生事件舆情环境下的群体智慧涌现模式与规律。研究结果表明，本研究所提出的方法能够从突发公共卫生事件舆情中提取群体智慧，同时发现，随着突发事件的演变，舆情的热度和群体智慧并不是线性平稳增加的，涌现存在临界现象和跳跃式前进的特征。舆情知识网络具有小世界、无标度网络结构，群体智慧主要集中于微博信息中，具有动态属性。
