Research on the Dissemination and Response of Network Public Opinion of Emergency Events in Colleges Based on Crowd Intelligence Thinking

The phenomenon of Crowd intelligence among college student groups has formed a Crowd intelligence network of college student edition through the Internet. The problem of network public opinion of college emergencies in the Crowd intelligence network has gradually become a hot topic for scholars to study. In view of this, this paper analyzes the challenges and existing problems of the network robustness of colleges in the Crowd intelligence network facing the network public opinion of emergencies. With the help of the life cycle theory in crisis management, the dissemination law of network public opinion of emergencies in colleges is studied, the development life cycle of network public opinion on emergencies in colleges is constructed by gestation period, outbreak period, diffusion period, repetition period, extinction period and long-tail period, and corresponding solutions are proposed for each period.


Introduction
The phenomenon of Crowd intelligence widely exists in politics, economy, humanities and other fields. With the development of Internet, the phenomenon of Crowd intelligence gradually presents a networked Crowd intelligence type economic and social form of internet of everything. As the main form of the mod-ern service industry and the future economic society, the related research of the Crowd intelligence network can promote the government governance activities to be more effective and more humanized, so as to avoid the possible chaos, turbulence and abrupt change to the greatest extent. However, in colleges and universities as a microcosm of society, the phenomenon of Crowd intelligence among college student groups has formed a Crowd intelligence network of college student edition through the Internet. The problem of network public opinion of college emergencies in the Crowd intelligence network is related to the fluctuation of college students' thoughts and emotions, and the security and stability of the campus has gradually become a hot pot of research for scholars.
College students have a strong ability to accept new things and are willing to accept new things, but they lack the ability to identify them. Especially under the stimulus of wrong ideological trends, they are very easy to lose their ideals and beliefs, choose the wrong value orientation, and confuse their way of life. Therefore, this paper will base on Crowd intelligence thinking and make use of the mass flow shock of public opinion data on the college network robustness in Crowd intelligence network, so that the normal operation of the network system of colleges can be guaranteed, and the students' emotions mapped by the network can be responded in the first time, accurately and comprehensively exposed to the public and handled efficiently. Thus, the network public opinion of college emergencies can be reduced from the point of explosion to the point of calming down, thus improving the credibility of the school.

Challenges Faced by Colleges in Dealing with Network Public Opinions of Emergencies
With the exposure of more and more public events in colleges and universities, colleges and universities are also involved in the whirlpool of public opinion. An urgent problem to study and solve is how to deal with them under the supervision of public opinion. If the network public opinion is not handled properly, the pressure of public opinion will soon upgrade and worsen the situation, which will not only lose the confidence of students, but also directly affect the image of the school. Therefore, in the changing environment of network public opinion, it is particularly important for schools to take timely and effective response measures [1]. 1) Scale expansion of netizen On the one hand, the social status of Chinese netizens is relatively low, which can be reflected from the professional level. Students and individual households/freelancers have the highest proportion in the total number of netizens in China, respectively. The proportion of unemployed/laid-off/jobless persons in the total number of netizens in China has declined, but it is second only to students, individual households/freelancers. On the other hand, the group polarization effect of Chinese netizens is obvious, and shows a trend of strengthening. In recent years' emergencies, netizens are increasingly influenced by the opinions of other members, and even become more extreme, emotional and irrational. If this irrational expression is allowed to spread and develop, it will depress the rational voice and confuse the dissemination of public opinion, resulting in the expansion of events and seriously affecting the rational development of events and positive response.
2) Activation of network public opinion orientation Chinese netizens' comments on various emergencies have reached an unprecedented level of activity, especially some emergencies with greater impact with strong comments in the new network media. These influential public opinions have brought strong social pressure to the governance of schools. If schools cannot effectively control these inappropriate speech and malicious incitement, it will eventually lead to more unscrupulous behavior of students' netizens in the new network media, the virtual network society will be more chaotic, and students' netizens themselves will suffer from it.
3) Pluralism of public values The rapid development of social economy and the growing differentiation of interest groups will inevitably lead to a large number of social contradictions and emergencies. Therefore, when the emergencies occur, the development of public opinion can see the expression of various extreme emotions of students' netizens, especially the messages and news comments in the online world. Many students' netizens are very easy to follow the trend impulsively without any clear reasons. From the perspective of the school, the student netizens' right to speak on the Internet also has two effects on the management and authority of the school in the development and dissemination process of network public opinions. On the one hand, the public opinion provides a convenient channel and method to enable the school to quickly understand the public sentiment and opinion. On the other hand, with the increase of information and the blindness of comments, it is easy to cause the unreasonable student netizen to cause the campus disorder. 4) Diversification of the public opinion field In the past, traditional media has always been the patent of news editors, journalists and some media organizations. Today, the public is the producer and disseminator of media, which has truly realized the communication mode of "public participation, instant sharing". Nowadays, the large amount of information in various forms of network new media cannot be fully understood, resulting in the emergence of personalized fast-food reading, which will cause the mileage and credibility of network news reports to be further implemented. How to improve the ability of schools to deal with emergencies on the network with relatively weak social control mechanism will be an important issue.

The Problems of Colleges in Dealing with Network Public Opinion of Emergencies
With the development and popularization of the network, the public is paying more and more attention to the network public opinion. Schools also pay close attention to network public opinion, and the quality of school response from the perspective of network public opinion is gradually improving. However, the net- work public opinion of emergencies also has the characteristics of concealment, instantaneity and suddenness, which will make schools lag behind and imperfect in dealing with emergencies [2].

1) Low ability to respond in time
With the rapid development of the network, "golden 24 hours" cannot meet the needs of the present era. Therefore, some public opinion research institutions put forward the "golden 4 hours" principle, and even some institutions put forward the "golden 1 hour" principle [3]. The increasingly frequent crisis of network public opinion has tested the school's response ability and posed a severe challenge to the image building of the school. The traditional coping modes are mainly manifested in inaction, lagging reaction, passive perfunctory, blockade and retaliation, which have seriously damaged and destroyed the school image.
With the rapid development of the Internet, the awareness of protecting public rights and interests has become mature, requiring schools to respond in the first time.
2) Low level of information disclosure For such types of events as information opacity, system absence and inaction, and information disclosure and dialogue can enhance mutual understanding [4], while analysis and decision-making can resolve contradictions, thus fundamentally preventing or calming events [5]. Silent or contemptuous attitude will give up an effective way to actively understand people's feelings and opinions, leading to unfavorable public opinion. If schools want to deal with emergencies efficiently and quickly, they should timely understand student netizens' ideas and communicate with them in time. However, there are still many schools still cannot clearly understand the principle, and in the face of public opinion crisis, the first step they take is to delete posts to block public opinion. Network public opinion response is to convey open, transparent, real and effective information to the public and the media, so as to eliminate doubts and nip the public opinions in the bud.

3) Weak management mechanism
At present, our colleges and universities have not yet established a set of scientific and effective mechanism for collecting, researching and utilizing network public opinion. Their ability of public opinion research and judgment is weak. They cannot find out the network public opinion in time to prevent it from happening, and their ways of dealing with the network public opinion are simple and crude. They often adopt the ways of closing, blocking, deleting, dragging and concealing to deal with the network public opinion, which is not only impossible to resolve contradictions in time, but also may even lead to further intensification of contradictions [6]. In the face of the network public opinion, the crisis monitoring system has not been established, and the crisis plan is unreasonable and standardized. In the face of the network public opinion, schools tend to be in a passive situation. In many cases, the relevant departments begin to respond only when the public opinion has entered a crisis state.

Network Public Opinion Dissemination Stage of Emergency Events in Colleges and Universities Based on Crowd Intelligence Thinking
Network public opinion of college emergencies is the political attitude, beliefs and values that students netizens convey through network media in response to emergencies in a specific social environment. Its essence is to gather, share and exchange incident-related information among relevant departments of schoolstudents-netizens-network media around emergencies. Therefore, the network public opinion of emergencies has the general characteristics of information ecosystem. Scholars at home and abroad have carried out a large number of case studies, and summed up the stage of network public opinion dissemination of emergencies. The representative ideas are three-stage theory [7], four-stage theory and five-stage theory [8], and some scholars have put forward multi-stage theory.
The division of existing public opinion stages of public emergencies is sorted out and summarize as shown in Table 1.

Measures for Colleges and Universities to Deal with Network Public Opinion on Emergencies under the Background of Crowd Intelligence Thinking
College emergencies are easy to get the attention of student netizens and the media, especially the major emergencies related to the interests of students' ne-   b) The response should be made timely. Schools should show their attitude and position at the first time of the incident. Whether the response is timely or not largely determines the duration of public opinion [9]. The quicker the response, the sooner the scope and influence of public opinion can be controlled.
If the facts of the incident have not been confirmed, the opinions and process of handling should be expressed in a timely manner. If this step is completed well, the network public opinion of the event will be moderated and controlled to a certain extent.
c) The altitude of response should be sincere. In order to get the recognition of students' netizens, attitude must be sincere. If the fault is obvious, then we must dare to assume responsibility without shirking and evading [10], so as to pull in the distance of students' netizens and reduce students' discontent to a certain extent. At the same time, when responding to the network public opinion, we should pay attention to the speech and behavior, and must not use the fuzzy words which cannot convey our ideas correctly or speak stereotyped in form. We must speak the truth to make the public understand. At this time, the better way of response is to let the news spokesman publish the unified information.

3) Diffusion period
The credibility of schools involved in public opinion incidents in the diffusion period has been greatly questioned, and the public has reached a fairly high degree of questioning. Schools should stand up decisively and make public and impartial responses by holding press conferences as respondents to the public. In addition, the speaker should popularize professional knowledge, timely understand and master the basic knowledge related to events, and be able to quickly adjust his position and methods with the progress of events, the transfer of contradictions, the fermentation of public opinion and the breeding of rumors. Students' netizens will not strongly question the information control, professional level, media literacy and public opinion response ability of news spokespersons.

4) Repetition period
During this period, the incidence of network rumors and students' public opinion is relatively high, students' netizens' attention has been quite extensive, and the situation of the incident is also quite well understood. Schools should communicate with the involved parties quickly, compress the time and space of rumor dissemination, speed up the response speed, and publish authoritative information. Otherwise, once rumors spread, students who do not know the truth will be more easily encouraged and cause greater riots. At the same time, the parties involved in the events should have a proper attitude and face the que- and publicly indicate the reasonableness of the practice.

5) Recession period
In order to avoid the recurrence of such emergencies, the departments involved in schools should summarize and reflect on the incidents, find out the deficiencies and shortcomings in their daily work, revise the corresponding system in combination with the media or the public's deep reflection on events during the recession, and standardize the behavior that causes public opinion, so as to avoid similar mistakes in their work in the future. At the same time, the school departments involved in the events shall repair their own image. If the image and credibility of the school are affected, or when public opinion erupts, it causes more serious image damage or loss of credibility because of inappropriate response, and then the school should also try to restore the image through the media to enhance its credibility.

6) Long-term tail period
Schools should deal with the relationship with the public and the media well, accept the supervision and criticism of the public and the media actively, satisfy the public's right to know and speak, properly handle the relationship among the school, the media and the public, reshape the image of the school and respond to the public's demands. Schools should improve the supervision mechanism, pay attention to improving the quality of managers, strengthen self-examination and self-supervision, and guard against hidden dangers. In addition, school network monitoring organization cannot relax the monitoring of crisis events, but should continue to observe, in order to prevent the recurrence of the crisis caused by rumors or unexpected factors, and prevent its resurgence.

Conclusion
Studies have shown that, the development life cycle of network public opinion on emergencies in colleges is constructed by gestation period, outbreak period, diffusion period, repetition period, extinction period and long-tail period, and corresponding solutions are proposed for each period.
