英文摘要：

Today, the resources of network inflate quickly, it has momentous significance for the task of the surveillance and management of network and leading the public to carry out the intelligence classification of the massive amount of information that released by the important network medium. To a large extent, it can solve currently the information of disorderly phenomenon. Owing to this, mainly implements the information intelligence classification on network media, based on the improved KNN algorithm, and then validates the validity of this improved algorithm. The result of the experiment indicates that the improved KNN algorithm can realize an effective intelligence classification to information that network medium released, the index of algorithm＇s performance can achieve the business demands which the work of surveillance and management of network requires the information intelligence classification. So it＇s feasible and effective to apply the KNN algorithm to the intelligence classification of the massive amount of information that the network medium released.
