摘要
为了获取突发事件案例中客观事物及其状态变化信息,将共性知识元模型引入到应急领域中,针对突发事件案例内容特征,从知识层面对突发事件案例进行结构化表示,进而提出一种基于知识元的突发事件案例信息抽取方法。该方法通过可定制的突发事件案例信息抽取模板,并结合规则匹配,能够实现对突发事件案例半自动化信息抽取,抽取结果存储到数据库中,可以为基于知识元的突发事件情景模拟仿真研究提供客观真实的数据支持。最后通过实验证明了该方法的可行性和有效性。
In order to obtain the information of the objective things and their state change in emergency case,this paper introduces common knowledge model into emergency field.According to emergency case's feature,structurally represent emergency case from knowledge layer.On this basis,it proposes a method for emergency case information extraction based on knowledge element.Through constructing the emergency case information extraction template that is customized,combining rules,we can carry out semi-automatic emergency case information extraction store the results into database and provide the objective and true data support for the research on analog simulation of emergency scenario based on knowledge element.Finally,an experiment is given to prove the feasibility and efficiency of this method.
