Risk Control in the Evolution of Public Opinion

The evolution of opinion in Internet social networks may result in several risk issues in digital era, which have garnered government attention, and develop in business. This chapter proposes an index to measure the risk level in opinion evolution within the framework of the SNDG model and then presents the upper and lower bounds of risks determined by the social network structures. Furthermore, the social network risk control (SNRC) model is developed to control risk evolution by adding minimum interactions; some desired properties of the SNRC model are presented and discussed.
