摘要
为了让民众更加清楚地了解突发事件的应急处置过程,提高政府公信力,提出并实现了一种从新闻报道中构建突发事件应急处置过程的方法.将应急措施看作三元组,构建训练语料,采用条件随机场(CRF)模型抽取三元组的元素,然后将应急措施按时间排序得到应急处置过程.所设计的基于CRF的三元组抽取模型的准确率为99.6％、精确率为93.8％、召回率为76.2％、F1值为84.1％.同时,通过对比抽取的应急处置过程和人工构建的应急处置过程可知抽取效果完全达到了实用水平.所提出的方法能自动准确地生成突发事件应急处置过程,为突发事件应急处置科学决策提供技术支持.
Abstract
In order to let the public know more about the emergency response process and improve the credibility of the government,this paper proposes and realizes a method of constructing the emergency response process from news report.The emergency measures were regarded as triples,the training corpus was constructed,the conditional random field(CRF)model was used to extract the elements of triples,and then the emergency measures were sorted in time order to get the emergency response process.The accuracy of CRF model was 99.6％,the accuracy was 93.8％,the recall was 76.2％,and the F1 value was 84.1％.At the same time,by comparing the extraction result of this paper and the manual extraction result,we can see that the extraction method of this paper achieves the practical level.This method can accurately generate emergency response process,and provide technical support for scientific decision-making in emergency response.
