Abstract

An influence drift index (IDI) and an influence stability index (ISI) of opinion leader nodes are proposed to capture the dynamic growth trajectory of opinion leaders in the process of public opinion evolution. The multidimensional features of user nodes are extracted to construct the influence index, and the change amplitude of the influence index in the time dimension is quantified, and this forms the basis for an influence index online evolution (INFOE) method. In this method, opinion leaders’ influence is regarded as the feature vector of dynamic change. The IDI for the opinion leader-audience layer is established from the three dimensions of contribution degree, recognition degree and dissemination degree of opinion leaders. Second, fuzzy formal concept analysis is used to establish the formal concept of opinion leaders and its poset to construct an ISI for the opinion leader-audience layer. Finally, the fluctuation degree of the influence index of opinion leaders in the evolution of public opinion content is quantified to realize the online evolution of this index. INFOE is verified and analyzed in this case. The empirical results show that the IDI reveals a certain correlation between the influence index of opinion leaders and the heat of public opinion in the process of event evolution, which can be used to monitor the time node of public opinion outbreaks accurately. The ISI reflects the fuzzy dependence of the influence index among opinion leader nodes, which provides a new theoretical exploration and research perspective for the multi-angle subdivision of opinion leaders.
