Brief description of the report.

Group consensus strategies investigate how individual preferences are aggregated into group preferences and are one of the keys to achieving group satisfaction. Traditional group consensus uses a static method to aggregate user preferences, without considering the interaction between group members, and cannot improve group satisfaction and the degree of accuracy of recommendations. With the development of social media such as microblogs, there are interactive behaviours between group members and a certain level of social network trust relationship is generated. This report introduces social network trust and group interaction decision-making into the study of group consensus integration problems, and uses social network analysis, group interaction decision-making and information fusion as methods and tools to study in depth the user trust line in the group consensus process and its influence mechanism on group consensus reaching. It mainly includes trust-based feedback mechanism and anti-manipulation mechanism.
