摘要: 新冠病毒肺炎疫情已经步入后疫情时期,以互联网用户为研究对象,探究后疫情时期民众的健康信息需求,以期为相关部门的信息发布和相关公共政策制定提供依据。文章以社会化问答平台“知乎”为例,利用LDA主题模型与人工标注相结合的方法构建用户健康信息需求编码体系,并通过周期划分,结合内容分析、主题分析、需求强度分析等,从时间和需求主题的维度揭示用户健康信息需求的特征及其演变规律。后疫情时期互联网用户的健康信息需求主要集中在新冠肺炎相关知识、疫情防控、社会影响三个方面。用户的核心需求是“疫情防控”,独特性需求表现为“新冠疫苗关注”。研究表明,后疫情时期互联网用户的健康信息需求依然具有较强的疫情敏感性,同时也反映了疫情发展及防控状 态。

Abstract: We have has entered the post- COVID-19 epidemic era. Taking the Internet users as the research object, this paper explored the health information needs of the public in the post-epidemic era, in order to provide the basis for the information release and policy making of relevant departments. Taking the social Q&A platform “Zhihu” as an example, a coding system of user health information needs was constructed by combining LDA topic model with manual annotation. The characteristics and evolution rules of user health information needs were revealed from the dimension of time and topic through cycle division, content analysis and needs intensity analysis. In the post-epidemic period, Internet users’ health information needs are mainly concentrated in three aspects, namely, COVID-19 related knowledge, epidemic prevention and control, and social impact. The core need of users is “epidemic prevention and control”, while the unique need is “COVID-19 vaccine”. The research shows that the health information needs of users are still highly sensitive to the epidemic in the post-epidemic era, and also reflect the epidemic prevention and control status.
