Research on the Establishment of Cross-Region Emergency Decision Support System under the Context of Social Media
[Purpose/significance] The rapid development of social media, social network, micro-blog and other social mediahave brought new opportunities and challenges to emergency management. Related works will not only fulfill and extend present theories in fields of emergency management, but also provide scientific basis and guidance for the cross-region emergency decision. [Method/process] On the basis of the careful consideration on the characteristics of social media data and the existing problems faced by cross-region emergency decision, a novel cross-region emergency decision supportframework based on multiple information sources fusion is proposed and constructed. Then five key issues for the perfection of the cross-region emergency decision support system are probed, and countermeasures are briefly presented. [Results/conclusion] Introducing dynamic web social media information into cross-region emergency decision and integrating it with other emergency information will help to improve the accuracy and effectiveness of emergency decision，which will play an active role in emergency decision analysis and emergency management.
