英文摘要	In "Internet+" era, how to real-time monitoring and build effective pre-warning systems of the network public opinion crisis has become a required courses for government departments and enterprises. This paper sufficiently considers the development, changes in laws and characteristics of the network public o-pinion crisis, and establishes a pre-warning index system with 7 indexes of network public opinion. Because of the final index redundancy and the lack of data, building the public opinion of Pre-Warning model based on PCA and SVM, and using PSO to optimize the parameters of SVM. Experiment shows the pre-warning index system of network public opinion and the model of PCA-PSO-SVM is effective and feasible.
