Abstract

The invention discloses a WEB public opinion trend forecasting method based on optimal model. The basic thought of the method is to firstly classify historical public opinion events to obtain several categories of opinion events, secondly clustering the time series plot of events in each obtained category to obtain sub-categories and finally obtaining the optimal model of each sub-category while ensuring the sum of mean-square errors is least to obtain the optimal model of each main category. When given an event to be predicted, the predicted event is classified and the optimal models obtained by early training to the category of the event are selected for matching, thus the model which is more suitable for the development trend of the event and the change proportion in matching can be selected; and inverse transformation is performed to the selected models according to the obtained change proportion so as to obtain the long-term development trend of the predicted event. Therefore, the defect that the existing network forecasting method can not forecast the inflection point can be overcome, the government and the supervision department can adopt timely and effective measures and the effects of network supervision can be better realized.
