Abstract
In microblogging, hashtags are used to be topical markers, and they are adopted by users that contribute similar content or express a related idea.

The proposed approach first trains a domain classification model with news content and news category information, then detects microblogs related to a hashtag to be its representative text, based on which we can classify this hashtag with a domain. Finally, we calculate the domain-sensitive popularity of each hashtag with multiple factors, to get most hotly discussed hashtags in each domain.…
