Abstract: Public opinion prediction is an important part of monitoring.In view of public opinion inflection point in the evolution process will affect public opinion forecast,based on ARIMA and gray prediction model,a prediction method based on inflection point was proposed,the mathematical model of segmentation and mirror processing was established.Finally,an example was used to verify the model,and the advantages and disadvantages of the model were summarized.Experiments show that this method can reduce the influence of inflection point and improve the accuracy of public opini-on prediction.

Key words: ARIMA, Gray forecast, Inflection point, Public opinion
