A Web Mining Based Measurement and Monitoring Model of Urban Mass Panic in Emergency Management

It is very important to discover the mass panic when city is in emergency. A traditional approach is to do a survey among urban mass, which would cost much time and money. In our opinion, a more suitable and effective approach is to do Web-based investigation which includes discovery, measurement, and monitoring. A framework including information retrieval, data mining, and area knowledge analysis is presented. Great efforts have been put to the urban mass panic measurement model in terms of over 10 indicators which have covered most relevant Web sites, consisting of portal, forums, BBS and other interactive Web sites. Experimental results are discussed at the end of the article.
