Activeness and cluster structure analyzing system and method based on network topics

The invention provides an activeness and cluster structure analyzing system based on network topics. The activeness and cluster structure analyzing system based on the network topics comprises a data acquiring and normalizing module, a data storage module, an application analysis module and an user interaction and display module; the user interaction and display module provides an interface for realizing user interaction and displaying data analysis results; the data acquiring and normalizing module is used for receiving an URL (Uniform Resource Locator) specified by a user and acquiring and normalizing the network data by virtue of a network data crawling subunit and a webpage data normalizing subunit; the data storage module is used for storing the normalized webpage data and providing analysis data to the application analysis module; and the application analysis module is used for deeply mining the activeness of the topics and a community structure based on the webpage clustering and hot spot mining, and s
