The Application Of Big Data In The Analysis Of The Public Opinion Of The Network Of The Unexpected Events

In the current economic environment,the market environment of all walks of life has become very complicated.In this context,the domestic and international emergencies continue to increase,the traditional mode of transmission has been gradually transferred to the network,the spread of its area to further expand,resulting in the network of public opinion caused by their difficult to control.And for the emergencies in the network caused by the network of public opinion,the traditional processing and analysis model is no longer adapt,replaced by information technology,data and intelligent technology analysis model.However,in the existing emergency network public opinion analysis,more biased in the analysis of the occurrence of emergencies and management,and for the upcoming start to make effective preventive mechanisms,and after the treatment of more For the "big things small,small things of the" approach,making the entire network public opinion can not be effective control,which led to the domestic network of public opinion is very serious.If not to control and improve,will inevitably lead to a chain reaction,thus affecting the country’s economic,social and political and so on.In view of this,this topic will be used as a research center,based on the characteristics of emergencies at home and abroad and the status quo and the sudden situation of the network public opinion,to find one of the shortcomings and problems,the introduction of large data,and then build a targeted analysis model and a systematic solution.In this solution,the solution is based on the application status of large data at home and abroad,the current situation of domestic emergencies in the network and the current situation of public opinion,and find the problems and potential risks.And then provide an effective direction for the follow-up analysis and research.Then,based on the characteristics,propagation,influence and definition of emergencies,the cognitive model is constructed to facilitate the subsequent analysis from the large data perspective,and then from the definition,characteristics,relationships,types and effects of the network to make a more detailed analysis and demonstration,and from the transmission path,the information publisher as well as information receiving and commentators,etc.,to discuss the analytical methods,management methods and supervision theories in this topic,so as to construct a corresponding analysis model for the follow-up to the public opinion of the emergencies.Then,from the technical point of view,The incident in the network of public opinion characteristics and influence,etc.,will introduce large data,In the analysis of large-scale data and network public opinion management and the balance point;Finally,based on the previous analysis and the wheel of the type of data,the use of large-scale data.From the disseminator,information publishers,information and other dimensions to build targeted system management program,and see the introduction of law,etc.,to build a matching with the monitoring system to facilitate the timely detection of the problem and give timely treatment.Among them,the explosion of Tianjin Port as an example,the theory of the introduction of which,from the perspective of information dissemination to carry out a more detailed analysis and discussion,compared the traditional analysis methods and large data analysis methods between the strengths and weaknesses And the corresponding analysis model is given.At the same time,based on the empirical analysis method,the feasibility and validity of the designed scheme are verified,and the significance and value of the large data in the bombing event of Tianjin port are pointed out.The corresponding analysis of the program,its choice and control of the basis,and then can be more timely,objective,fast and effective treatment,rather than in the media and news media such as further fermentation and deterioration.In short,this topic through the literature search,data analysis and field visits,etc.,theintroduction of large data into the burst of time public opinion analysis,and then build a corresponding analysis model;then with the advanced experience of foreign advanced In front of the analysis model introduced in China,based on the domestic conditions and the people,for the emergencies in the network management and public opinion situation,from the perspective of large data to build a systematic monitoring system,and then for the domestic network of public opinion in the event Of the research to provide another cognitive direction,while expecting the proposed systematic approach can improve the current network environment for the country’s political,economic and social and so on to make more effective protection.
