The evolution of the opinion of an agent is often uncertain in social networks, especially
when they have to communicate with agents holding opposing opinions on a certain topic. In …

Trust and distrust are common in the opinion interactions among agents in signed social
networks. To explain the gradual evolution of the trust/distrust level between agents due to …

Most existing opinion formation processes apply one opinion dynamics model. However,
this article combines opinion formation and complex networks to innovatively develop two …

In social networks with mixed trust and distrust relationships, polarization is a common class
of opinion evolutionary phenomena. Existing studies have generally believed that structural …

This paper considers a group decision-making mechanism for a group of social agents with
ambiguous interactions. First, a fuzzy inference approach is introduced to describe bounded …

Classic models on opinion dynamics usually focus on a group of agents forming their
opinions interactively over a single issue. Yet generally agreement cannot be achieved over …

Existing opinion dynamics models often fail to consider the relationship between one agent
and people two degrees of separation from the agent. In addition, no accurate weight …

Hybrid opinion dynamics which involves two types of individuals (ie, leaders and followers)
communicate in real time and share opinions and knowledge have been widely used in …

In this paper, we study the evolution of opinions where people are not sure of their own
opinions and/or their opinions may be conflicting to others' in social networks. We model two …

Trust and distrust relationships are both common in social interactions of group decision
making (GDM). Traditionally, trust/distrust levels are fixed in the opinion evolution process …
