| The coming of the era of big data,the dissemination of online public opinion information for emergencies presents the characteristics of interaction,complexity,and diversity.Using big data technology to strengthen the ability of online public opinion risk early warning of emergencies is an important task that the current government needs to carry out.Has important practical value.In recent years,with the development and application of big data technology in my country,the Chinese government has achieved some results in the early warning of public opinion risks in emergencies in the era of big data.The ability to collect public opinion information of data has gradually improved,the research and judgment model of public opinion information based on big data has gradually matured,and public opinion information disclosure institutions based on big data have begun to be established.At the same time,there are also some problems in the use of big data technology in the online public opinion risk warning of emergencies.The main problems are the insufficient data acquisition content in the public opinion risk warning,the inaccurate grasp of the data mining power in the public opinion risk warning,The information sharing object in the public opinion risk warning is not clear enough,and the timeliness of information release in the public opinion risk warning is improperly evaluated.Through an in-depth analysis of its causes,it is found that the main causes of the problem are: the data collection ability in the public opinion risk warning needs to be improved,the data analysis technology in the public opinion risk warning needs to be improved urgently,the positioning of the information sharing mechanism in the public opinion risk early warning is unclear,the information release system in the public opinion risk warning is weak.Combining the experience in the application of big data technology at home and abroad,it is believed that in the era of big data,it is necessary to build a scientific,efficient,complete,and systematic emergency network public opinion risk early warning mechanism.First,establish a big data early warning concept of online public opinion risk early warning for emergencies,including a correct understanding of the role of big data technology in promoting online public opinion risk early warning of emergencies,scientifically standardize the use of big data technology in the online public opinion risk warning of emergencies,reasonably design the realization goal of the online public opinion risk warning of emergencies in the era of big data;Second,innovate the big data risk early warning technology support of the network public opinion of emergencies,big data information collection technology including network public opinion in emergencies,big data information recognition technology for emergencies network public opinion,big data information mining technology for network public opinion in emergencies;Third,optimize the construction of a big data mechanism for online public opinion risk early warning of emergencies,including the data risk integration identification mechanism of network public opinion in emergencies,accurate evaluation mechanism for information risk of network public opinion in emergencies,timely response mechanism for data risk of network public opinion in emergencies;Fourth,improve the big data risk early-warning guarantee system of network public opinion in emergencies,including the improvement of legislative guarantees for the early warning data of online public opinion risks in emergencies,innovate the collaborative system of online public opinion risk early warning data for emergencies,establish a sharing system of online public opinion risk early warning data for emergencies. |
