社会公共事件网络信息生态链的构成要素包括事件信息、节点、路径和环境。节点具有短时间段内激增、类型和素质多样化、行为由偏好驱动、分解行为有限等特点;社会公共事件网络传播有单点扩散、树形传播、订阅和推送3种主要方式;基于此,析出当前社会公共事件的网络信息生态链模型,结合问卷调研,分析模型所存在的信息病毒式传播缺陷、网络舆情和实际舆情有差异、节点覆盖面窄、政府作用有限等问题,提出模型优化策略。
Social public events The elements of the network information ecosystem include event information, nodes, paths and environments. The nodes have such characteristics as surge in the short period of time, diversification of types and qualities, driven by preference and limited decomposition behavior. There are three main ways of social public event network dissemination: single point spread, tree spread, subscription and push; Presents the model of network information ecological chain of current social public events, and proposes a model optimization strategy by combining the questionnaire survey, analysis of the existing information model of the virus’s viral communication defects, the network public opinion and actual public opinion are different, the node coverage is narrow, the role of the government is limited.
