Abstract

The invention discloses a topic detection and tracking method for a microblog. The topic detection and tracking method for the microblog comprises the steps of grouping a created microblog, comments and forwarded of the created microblog together, and inputting as the same cell; extracting feature words from a microblog text to obtain a feature word list, and counting the word frequency of each feature word at an input cell; calculating the weight of the feature words in the feature word list to obtain VSM (Vector Space Model) vectors; sequentially comparing the similarity input VSM vector with the existing microblog cluster in similarity by the incremental clustering algorithm so as to obtain the microblog cluster with the maximum similarity; including the microblog into the microblog cluster with the maximum similarity when the similarity of the VSM vectors and the existing microblog cluster are higher than a threshold, and otherwise, creating a new microblog cluster on the basis of the microblog; screening the microblog clusters to obtain a topic cluster. With the adoption of the topic detection and tracking method for the microblog, a user can know the mainstream of public opinions and social hot spots all the time through the microblog, and the support is provided for further analysis on the public opinions.
