Abstract  In order to get dynamics of Web information timely, an online Web topic clustering approach based on Single-Pass algorithm is researched. The clustering process of this approach is analyzed firstly,and the key problems including extracting and weight calculating of features as well as representation and modification of topic cluster are deliberated. Experiment is designed to compare the effects of different weight factor of features in title, weight calculating and normalizing methods of features and the vector dimension of topic cluster on cluster quality and time efficiency.
Key wordsInternet public opinion      Topic mining      Online clustering      Single-Pass
