AMHK: A Novel Opinion Dynamics Affection Mobilization-Based Hegselmann-Krause Model

The existing opinion dynamics models based on the impact of opinion leaders tend to only consider the impact of opinion leaders on normal individuals, but ignore the impact of normal individuals on opinion leaders. Normal individuals in social networks can also change the opinions of opinion leaders by initiative affection mobilization. In this paper, an affection mobilization leadership index (AMLI) is used to identify opinion leaders and influential agents who can mobilize affection initiatively. A novel opinion dynamics affection mobilization-based Hegselmann-Krause model (AMHK) is then proposed. Extensive experiments on both artificially generated and real-trace network datasets verify the effectiveness and efficiency of the proposed model. Appropriate proportion of influential agents can promote the reach of consensus, while excess influential agents could lead a consensus with fragmented opinions, which provides a significant train of thought in guiding public opinion.
