Hashtag(the topical words of a micro-blog)is a kind of topic label of microblog created by publisher,which can help users find hot topics efficiently from the massive micro-blog data.Different Hashtags created by different publisher may describe the same topic.Thus mining the relevance between the Hashtags will help to find hot topics more efficiently.In this paper,a wide range of features were explored to analyze the topical relevance between Hashtags,such as the Hashtag text,content of the related microblog,the time of occurrence and the co-occurrences of Hashtags.The experimental results show that the proposed features are helpful for topical relevance analysis of Hashtags.
