Abstract:

The sudden change phenomenon in group opinion in online communities is becoming increasingly prominent and needs to be described and predicted by reasonable methods. Combining catastrophe theory with resilience modeling, resilience index prediction methods are proposed for sudden changes in group opinion of online communities. Taking Xiaomi community as an example, the catastrophe model is fitted and the resilience calculation is performed. Then the method is verified and confirmed from several perspectives, and the stability of the resilience threshold under different community sizes is tested through comparative experiments. The influence of key variables on group opinion and the relationship between resilience index and fluctuation of product reputation are discussed for the actual case of Xiaomi community. The contribution of this paper is the establishment of the resilience index prediction method for the sudden changes in group opinion in online communities. The actual case study shows that this work can quickly grasp the level of group opinion in online communities and predict the fluctuation of it, providing support for community management decisions.

Key words: complex systems, group opinion, catastrophe theory, resilience
