Network Propagation Algorithm And The Intervention Of The Emergency Countermeasures

With the unceasing development of human society, public events are occurring with new features, such as "9.11" terrorist attack on the United States in 2001, the first occurrence and spread of the SARS epidemic, the China's Wenchuan earthquake in 2008, as well as the global financial crisis that originated from sub-loan in U.S. in the same year. In addition, China's overall rapid economic development is unbalanced with the regional economic development, making the complex relationship, which may cause a lot of social problems. However, due to the lack of understanding dealing with such unpredictable events, it has been a massive challenge for human society to prevent such occurrences. Therefore, it has been a massive challenge for the government to set up an emergency management system mechanism to face all kinds of risks.However, the unconventional emergency management is "scenario-dependent" type with great potential for original innovation. Human beings can hardly forecast this kind of events beforehand, and lack the enough understanding, being difficult to prevent beforehand. The unconventional emergency management involves in such research fields as the policy decision science, the information science, the behavior psychology and so on. In addition, emergency management has been put emphasis on in the universal research area from 2002, so our country seems to develop quickly in this domain start. So it may be easier to obtain the scientific achievement and make international influence.This article can be divided into six chapters:ChapterⅠpresents the research background, the selected topic significance, the research technique, esc; ChapterⅡintroduces emergency theory and network media characteristics; ChapterⅢintroduces the network emergency information dissemination and make out a proof; Chapter IV displays an example to discuss the network emergency dissemination model and the conclusion; Chapter V makes concrete proposes and suggestions to the network emergency dissemination; Finally, the conclusions and outlook.This article is to discuss the characteristics and rules of the internet emergency, and to propose such method as "the scene - dissemination - decision-making - deal with". Through this kind of new angle of view research, it aims to provide a new opinion and frame to the research of intervening measures of internet emergency event.
