| Abstract: | An index for Internet public opinions crisis early-warning is created.Based on the index,the mathematical model of BP neural network is applied to the internet public opinions crisis early-warning.Thus the warning model based on BP neural network is built.The quantitative evaluation for Internet public opinion security is carried out.Combined with example,the model is analyzed and validated by the simulation experiment. |
