In order to improve the public opinion guidance ability for public health events in the Internet era, and improve the the problems of the traditional public opinion guidance mechanism, we analyze the public opinion guidance and communication mechanism based on the Internet era, and analyze the guidance software and software system, and related technical requirements? subsequently, the efficiency analysis of the public opinion guidance and communication mechanism of the multitask learning network was conducted; the results show that the public opinion guidance and communication mechanism of public health events based on the multitask learning network can effectively improve the diagnostic and early warning ability and diagnostic accuracy of the public opinion fermentation in public health emergencies, reduce the difficulty of guiding the public opinion fermentation of public health emergencies, and effectively improve the success rate of guidance for such events. In the Internet era, the public opinion guidance and communication mechanism based on the multitask learning network has improved the public opinion guidance ability for public health events, and it provides a research direction for the development of the network public opinion guidance system for unconventional public health emergencies in the future.
In order to improve the response ability of journalists to public emergencies, this study uses the computer simulation research method, based on Shannon’s information theory and the basic theory of journalism and communication, constructs the general model of public emergencies based on the statistical results of big data, and constructs the irrational natural person game model of four types of news communication participants. In the simulation analysis, it is found that in the face of public emergencies, journalists, on the one hand, firmly implement the publicity caliber, strengthen the amount of creation, and improve the forwarding amount and approval amount of manuscripts under the artificial intelligence news system. On the other hand, they should achieve effective interaction with nonofficial news media such as we media, and the subjective news department should provide effective guidance and guidance to the media.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
