Design and Implementation of Public Opinion Safety Monitoring System from the Perspective of Rumor Tracing Governance

At present, with its special user anonymity mechanism and almost unlimited freedom of speech, Weibo has rapidly grown into a representative of mainstream social media platforms, but at the same time, it also gives criminals the opportunity to spread rumors. When some rumors aimed at inciting public emotions, selling anxiety and creating panic spread wildly on Weibo, it is easy to expand public opinion unprecedentedly, thus damaging the order of Internet environment and threatening national ideological security. Therefore, in view of this reality, on the basis of topic tracing, this paper establishes a rumor source tracing mechanism based on user influence and time label, so as to achieve rumor source suppression and root rumor refuting. This mechanism helps to stick to the important position of network information space created by emerging media, and guarantee the security of public opinion and ideology in the current vision of new media.
