| 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。

| Abstract: | This research proposes an approach to extract collective intelligence from public opinion during public health emergencies,and reveals the pattern and rule of the emergence of collective intelligence.Taking the topic of herd immunity as an example,we extract the triples contained in microblog posts and comments to structurally represent the public’s knowledge by using the Relation Extraction with Dependency Parsing method.In this study,we explore the pattern and rule of the emergence of collective intelligence based on the triplets of public opinion and network topology.The research results show that the method proposed in this study can extract collective intelligence from public opinion during public health emergencies.Concurrently,we found the heat of public opinion and collective intelligence does not increase in a linear and steady fashion.There are critical phenomena and leaping forward characteristics with the development of emergencies.Public opinion knowledge network is limited and has a scalefree network structure.Collective intelligence mainly concentrates in microblog posts with dynamic properties. |
