Abstract

In view of the requirements for high reliability and strong time constraints in emergency rescue under disasters, an improved template-based information search method is proposed to meet these requirements. The method builds a search template based on features of emergency rescue field. Based on the HTML structure and template, the valid information in webpages can be extracted. A reliable correction method about the webpage updated time is composed after judging the extracted webpage updated time. Finally, the similarity between the webpage and event is calculated based on the event model. Through the relevant comparison and experiment evaluation, the method is proved to be able to improve the precision about Web information search in emergency rescue under disasters.
