Abstract

Abstract: Microblog topics play an important role in public opinion. The effective identification of key users in microblog topics is key for microblog public opinion mining. In this paper, we select topic-related microblog messages based on topic features. Candidate key users are selected according to the microblog topic user graph and edge weight. Key users of microblog topics are ranked according to the users' trust values. Experiments on Sina microblog topic datasets show that our method can mine high quality key users that lead to the formation of microblog topics in the early stage.

Key words: trust model, microblog topics, key users mining
