Abstract: Existing work has been focused on topic evolution of long text.This paper aimed to that of short text.We proposed a microblog topic evolution algorithm MTERR based on retweeting relationship.Firstly,we utilized a topic model to obtain topic information from microblog messages by combining retweeting features and time characteristics.Then,we built a topic correlation function to generate a topic evolution topological graph by incorporating topic content and retweeting relationship.Experiments on the real-world microblog datasets show the feasibility and effectiveness of our proposed method.

Key words: Microblog,Topic evolution,Short text,Topic model
