As the network public opinion possesses the features of various topic, complex content and large amount data etc., this paper constructs a multi-level index system of network public opinion analysis which is consisted of three level indicators. And then, network public opinion forecasting model is established with the grey forecasting method, and the early-warning model is established through the pattern recognition method. This paper selects 60 network public opinion events as training samples, establishes the classifying discipline of network public opinion level, and tests the usability of the forecasting and early-warning model. The forecasting and early-warning need large amount of data and complicated calculation, then it puts forward the whole frame of constructing the system to process data.
