Challenges of Events Detections on Microblog Platforms

Microblogs have dramatically changed the mechanism of information propagation. It has been an inevitable issue for governments and enterprises to face the challenges that microblogs bring to public safety management. Since 2010, a lot of emergent events were firstly reported in microblogs, and this trend is even becoming more and more prominent. As microblogs have shown much influence in public safety and sentiment management, governments and enterprises have to employ effective ways to monitor and predict emergent events in microblogs; otherwise when emergent events in microblogs happen, they will be in a passive situation and even the society’s stability will be affected. Based on the properties of microblog information and its diffusion, this paper presents a survey on the events detection from microblogs, and recent advances on some key related issues are especially focused and discussed. Finally, we give a framework for events detection on microblog platforms and its key issues are discussed, which are expected to bring valuable references for the researches in microblog information extraction.
