| In the age of the Internet,the attention of online audiences has shifted,and the advantages of the old media in the dissemination have continued to weaken.The influence of new media has been continuously expanding and flourishing.The popularity of socialization has spawned various types of self-media platforms,such as official Weibo,WeChat public account,QQ public account,today' s headline media platform,and various types of live broadcast platforms and short video platforms that have appeared in people's eyes in recent years.Various types of self-media platforms that springed up have become the main force in the development of new media.In the era of new media,everyone can publish what they see and hear to cyberspace.The content of the internet is no longer generated by professional websites or feature groups.Instead,it is the participation of all netizens and the creation of equal rights.Everyone is a network of information.The creator of it is also a communicator of network information.In such an era,the threshold for the dissemination of information has been reduced at an unprecedented rate.The "citizen reporter" has exposed all kinds of social issues to the general public and has been widely disseminated in the Internet field.This has led to heated discussions among the public and further formed a network hotspot event..Network hot events affect people's emotions and behaviors.If they are allowed to develop,they may cause group polarization or trigger a public sentiment crisis,adversely affect the society,endanger the network environment,undermine social harmony,and even trigger the public to the government.Dissatisfaction,but the occurrence of network hotspot events is full of chance and unpredictability.Therefore,it is necessary to study the emotion propagation characteristics of the network hotspot events to facilitate the healthy and orderly development of the network environment and the social harmony and stability.In this paper,by sorting out the domestic and foreign literature results and the latest statistical reports,yearbooks,and bulletins published in China,we have identified the three dimensions of the emotional spread of network hotspots in the new media era,and selected appropriate research methods for the network hot events.Conduct a comprehensive analysis.Firstly,select the "Shanghai police smashing child incident" as a typical case,use the web crawler tool to obtain relevant data in the Sina microblogging platform,and clean the data through the pre-processing process to obtain event-related corpus as the data base for this study..Secondly,based on the emotional mediation and strength calculations,keyword analysis and topic mining,combined with the new media's era background and network information life cycle theory,three dimensions are derived from the sequence of emotional communication:temporal characteristics,behavioral characteristics and group characteristics.The characteristics of the emotional spread of the network hotspot events in the new media era are discussed respectively.The results show that:1)The network hotspot events in the new media era are faster and the information update cycle is shorter.The entire life cycle does not experience a significant growth period.It is an explosion that converges in a very short period of time and quickly reaches its peak.2 The occurrence of network hotspot events may be distorted and amplified under the influence of the public's emotional impulses.It may also be used maliciously to disseminate false and harmful information.3 In the case of unclear information,the public is easily affected by the most significant opinions in the public opinion field,resulting in misjudgment in the untested circumstances.Responsible parties in response to public opinion,the choice of screening video does not quell public opinion,but instead cause a larger-scale discussion,proper disclosure of information,and take the initiative to help calm public opinion and resolve public negative emotions.Finally,based on the research results,this paper proposes 1 to establish and improve the network public opinion management mechanism.2 Regulate the network information dissemination environment.3 To broaden the three guiding measures for government network information.This research provides new ideas for the dissemination and control of hotspot events on the network,expands the application of sentiment analysis methods,and is beneficial to enrich existing research results,and provides reference for government departments to formulate targeted countermeasures and preventive measures. |
