Public opinion field trend prediction analysis method based on quantitative calculation

The invention discloses a public opinion field trend prediction analysis method based on quantitative calculation, and belongs to the technical field of public opinion analysis, and the method comprises the steps: S1, obtaining basic data; s2, on the basis of the obtained basic data, carrying out standing detection and standing trend analysis based on a speaking opportunity factor, and constructing a public opinion trend judgment rule to generate a sample set; s3, constructing a public opinion trend prediction neural network model TFNN based on the speaking account and the speaking content; and S4, generating sample data obtained by a sample set according to the construction trend judgment rule in the step S2, training the TFNN model in the step S3, and obtaining a public opinion trend prediction result. Scientific and effective decision suggestions can be provided for scientific governance of the network society in the new period and judgment of the public opinion trend of the media platform. 本发明公开了一种基于量化计算的
