- Abstract:
-
Microblog topic detection is a special type of topic detection. The traditional topic detection algorithms do not work well in special situations for Chinese microblogs. In this paper, a topic detection method cater to the user community of microblogs is proposed. Firstly, the users’ interests were analyzed by using the LDA(Latent Dirichlet Allocation) topic model on the text of microblogs generated by users/bloggers. Then the user/follower network associated with users’ interests was created and partitioned into different communities so that the users in the same group were not only densely connected but also shared similar interests. Then, the topics of interest in each community were detected. Together, this provides a microblog topic finding method that faces a user’s community and combines the importance of words as well as an ε neighboring graph. The experimental tests show that the method can effectively eliminate microblog noise, compute the importance of words, and rapidly and accurately obtain the topics of interest of each community.
