摘　　要：把握新冠疫情下的危机信息演化特征,可以为公共卫生危机信息的精准管理提供科学依据。通过爬取微博中与新冠疫情相关的危机信息并进行语料预处理,采用LDA模型对预处理后的数据进行主题识别,对主题进行可视化并分析其演化特征。结果显示:公共卫生危机信息种类复杂多样,且具有迭代性特征;危机信息主题内容、强度随疫情的变化而变化;官方与公众发布的危机相关信息在主题内容、强度方面契合度较低等。最后,提出了公共卫生危机信息管理对策建议。Grasping the evolution characteristics of crisis information under the new coronavirus epidemic can provide scientific basis for the accurate management of public health crisis information.By crawling the crisis information related to the new coronavirus in microblog and preprocessing the corpus,this paper uses LDA model to identify the theme of the preprocessed data,visualizes the theme and analyzes its evolution characteristics.The results show that the types of public crisis information are complex and diverse,with iterative characteristics;the theme contents and intensities of crisis information change with the change of epidemic situation;the crisis related information released by the government and the public has a low consistency in terms of theme content and intensity.Finally,it puts forward the public health crisis information management countermeasures.
