摘要: 近年来国内外地震灾害给人类的生命财产造成了巨大损失。海量的互联网地震灾情信息可为应急响应和及时救援提供决策支持的依据,因此互联网灾情信息高效快速处理需求迫切。针对地震互联网灾情信息处理的研究,定义了地震事件模型、网页对象模型等,用极限方法定义Web信息收敛性,刻画了互联网灾情信息传播特点。根据灾情信息时效性特点,提出了一种支持动态收敛性的Web信息抽取算法,完成互联网灾情信息提取。提出一种针对灾害信息随时间的变化进行时序统计的方法,形成信息统计报告,为制定救援决策提供依据。设计并实现了面向地震应急响应的互联网信息智能处理系统,并进行了工程实践验证。

Abstract: In recent years, the domestic and international earthquake disaster has caused huge losses to human life and property. Massive earthquake disaster information on the Internet can provide the basis for decision support for emergency response and timely rescue, so there is an urgent need for efficient and rapid processing of the disaster information. To study the information processing of the earthquake disaster in the Internet, the seismic event model, webpage object model, etc. were defined, and the convergence of Web information was defined with the limit method. The characteristics of the Internet disaster information dissemination were described. According to the characteristics of the timeliness of disaster information, the Web information extraction algorithm was proposed, which supports dynamic convergence. The method of time series statistics for the change of the disaster information with time was presented, and the information statistic report was formed, which provides the basis for rescue decision making. The intelligent information processing system for earthquake emergency response was designed and implemented. The models and methods were verified in a practical engineering project.

Key words: earthquake disaster, emergency response, information extraction, data cleaning, multi-document summary
