In this study, we analyzed the evolution of online public opinion on emergencies using a new Stochastic Petri Net modeling approach. First, an intuitive description emergency development process was conceptualized from life cycle law perspective. Then, based net theory, isomorphic Markov chain model constructed to simulate emergencies. Finally, four real-life cases were selected validate and analyze model, demonstrating that evolutionary leaps, complexity, critical nodes, rate, execution...
