- Nowadays, many unexpected topics in the society initiate on the microblog platform and spread rapidly, and some of them finally become hot events. The technology for detecting these hot events on the microblog platform, has exerted a very positive influence on the discovery of the latest social hotspots and the timely perception of the internet public opinion. This paper analyzed the studies for detecting microblog hot events, and disclosed the existing methods may omit the untagged microblogs and thus lead to the failure to detect the subevents. To address this issue, we combined Hashtag and Time with the topic model of LDA, and proposed the TH-LDA model to improve the effectiveness of hot events detection for Chinese microblogs. Experiments on microblogs datasets demonstrate that the proposed TH-LDA model can effectively obtain untagged microblogs, and then realize the subevents detection of hot events with a high accuracy.
