| Abstract: | In this paper,a network-traffic based topic extracting and analyzing method is introduced.The new topic definition for web2.0 and the classification of user behavior is given;the detecting method of user behavior,topic extracting method,and data storage algorithm is also proposed.At last,a prototype of topic collector based on network traffic is implemented;the testing results show that the user behavior and the hot topic can be collected and detected effectively and correctly,and the new method provides a new data channel for analyzing public opinion. |
