Abstract:

We analyze the evolution of the network hot events based on the value added theory. The emergence of the precipitating factors, the formation of generalized belief, and the completion of mobilization for actions are three crucial phases of the evolution of the events. We also design a monitoring model to analyze sensitive factors, the formation and diffusion of the emotions of public opinions in the events. Based on this, we develop a network public opinion intelligent monitoring system (NPOIMS). And the public opinion monitoring system is built up by  takes the X city in the west of China as the instance object. All kinds of public opinion information of the X city are monitored. The hot words are refined, and the public opinion is analyzed. And the analysis results are provided to the government departments as a decision support to guard public opinions and dispose the events.
