With the development of Internet, Network public opinion has been serving an import role in reflection of social public opinion. As there are a large number of websites and forums on the Internet, we need a powerful crawler system which can meet the demands of opinion mining.

In this article, we introduced the design and implementation of a distributed crawler system for opinion mining. We also introduced some extra parameters such as keywords count and published time into the ranking and refreshing strategies. Experimental results demonstrate that the system can well support different sites, and the improved strategies can greatly enhance the crawling and monitoring efficiency.

Network Public Opinion is significant in maintaining social harmony and stability and promoting transparency in government affairs. However, with the development of economy and transformation of society, our country has entered a high-risk period, which is full of unexpected public events. Unexpected mass accidents also cause hot discussions among the Internet users once they are exposed on the network. Different ideas, opinions, emotions, and attitudes about unexpected public events will be collected and collide on the Internet. It makes Network Public Opinion play an increasingly important role in the evolution of unexpected public events. It could promote the spread and upgrade of unexpected public events and bring more and more profound influence on to our social life. We use the case study method to analyze and solve the problems by applying the dynamic principles of the SIR epidemic model, comprehensively considering the social environment and various influencing factors, and constructing a mathematical model for the spread of network group events. The study uses Matlab to simulate the change trajectory of the number of participants in the network group events. By adjusting the number of contacts φ in the model, the development of network group emergencies can be effectively controlled and managed. As long as the government takes timely intervention measures, the dissemination of network group events can be basically controlled. Combined with public opinion big data to discover the important factors affecting the spread of public opinion, the control effect is obvious.
