| With the rapid development of the Internet,the influence of public opinion has become stronger and stronger.The public's attitude towards the degree of public trust is the credibility of public opinion,while financial public opinion refers to the public opinion about economic activities.Generally speaking,financial public opinion is based on all aspects of the operation of the national economic system,covering capital markets,funds and foreign exchange,economic policy,companies and industries,market and legal system,environment and science and technology,economic figures,etc.Financial public opinion affects the attitudes and behaviors of the general public and investors.While investigative reports,stock market reports,predictive reports,policy interpretation reports and investment and financial reports in the financial field meet the information needs of the audience,their false public opinion also has an inestimable negative impact on the social and economic system,especially on the related public opinion concerning the capital market.It damages the legitimate rights and interests of listed companies and investors.In view of false financial and economic public opinion,at this stage,besides strengthening the legal and institutional construction in the field of public opinion,relevant scholars have also studied technical means to monitor and intervene in it.For example,a fast detection system for false financial and economic public opinion based on network financial and economic public opinion and an effective suppression algorithm for reducing the diffusion range of high-impact financial and economic public opinion.However,there are still some problems in these methods,such as the limited amount of data processing in a certain space,the failure to establish a unified standard of data rules for reliability detection,the failure to integrate into natural language processing,the low degree of automation of detection and so on.Therefore,it is of great social significance to design an efficient and accurate detection framework.From the existing research,we can see that the occurrence of financial and economic public opinion is accompanied by the changes of corporate financial,non-financial and public opinion indicators.Therefore,the fluctuation of relevant analysis indicators can also reflect the development process of public opinion events.Therefore,we can judge whether public opinion is credible or not according to the change path of corporate financial,non-financial and public opinion indicators,and transform the change of public opinion status.For the rule model,the change of state is verified by detecting the rule model to judge whether the public opinion is credible or not.Model checking is an automatic verification method used to verify the correctness and reliability of the temporal logic relationship of complex systems.If the state transition relationship of financial public opinion is modeled,the model checking can verify the correctness of the model and play the role of public opinion checking to verify the credibility of public opinion.This paper designs a framework for the state characteristics of financial public opinion and the characteristics of model detection technology,and finally forms a complete financial public opinion detection system.Firstly,the state of public opinion is extracted,and the state entities are extracted for financial indicators,non-financial indicators,public opinion indicators,etc.Then,the state transition relationship is formed according to the time series relationship,and finally the path model to be tested is formed.At the same time,the case data of financial incidents are collected,and the inspection rules are extracted to form a database of inspection rules.The credibility of public opinion is verified by the model detection of the state transition relationship of public opinion.Experiments show that the system can effectively detect financial and economic public opinion,and at the same time,it provides theoretical support for public opinion detection under the temporal relationship. |
