As the third media as the network is, which makes the monitoring and the early warning of theinternet public opinion be the realistic subject and severe challenges.

Based on the existed works, considering the complex network theory as thetheoretical foundation, this paper does some study on the evolutionary process model of theinternet public opinion, trying to analysis the evolution mechanism of public opinion in theinternet, and providing some theoretical support and guidance method for network public opinionmonitoring and prediction.
