摘要

在现实生活中,有关疫苗的信息通常是通过异构网络传播的,与同构网络相比,异构网络的舆论爆发速度更快。考虑到异构网络的复杂性,我们建立了网络易感-转发-免疫(NET-SFI)模型来描述实际社交网络中的信息传播模式。根据社交网络中可联系用户的数量对节点的状态进行分类,NET-SFI 模型重点关注网络结构和用户异质性。我们采用数据模型驱动法进行模型验证,包括来自中国新浪微博的两类 COVID-19 疫苗信息。我们的参数敏感性分析表明,节点度在导致舆情爆发方面具有重要意义。此外,基于我们的分析研究得出的相应结论有助于设计有效的疫苗信息传播策略。

Modeling and analyzing network dynamics of COVID-19 vaccine information propagation in the Chinese Sina Microblog

Information about the vaccine is usually spread through heterogeneous networks in reality, where public opinion bursts out faster than in homogeneous networks. Considering the complexity of heterogeneous networks, we develop a network susceptible-forwarding-immune (NET-SFI) model to describe the patterns of information propagation in the actual social network. Classifying the states of nodes according to the number of users can contact in the social network, the NET-SFI model focuses on the network structure and user heterogeneity. We adopt a data-model drive method to conduct the model validation including two types of COVID-19 vaccine information from the Chinese Sina Microblog. Our parameter sensitivity analyses show the important significance of node degree in causing the outbreak of public opinion. Moreover, corresponding conclusions based on our analytic study are conducive to designing valid strategies for vaccine information dissemination.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
