【摘要】 灾害情景生成是对灾害进行模拟仿真的基础,有效的情景需要真实合理数据来支撑,针对情景生成过程中出现最普遍的一个问题:如何保证承灾体的空间属性赋值的合理性。借鉴共性知识模型理论,形式化表示承灾体及其属性,从知识层面抽取三类承灾体知识元实体化时出现的空间属性赋值失实的现象;对共性知识模型进行实例化得到承灾体属性模型和属性关系模型,分析承灾体空间属性间的约束关系,建立空间属性约束模型;进一步,参考框架理论的通用表示形式,形成空间属性约束模型的BNF式基于框架的约束关系表达式,以便存储调用。最后给出模型的应用实例。
【Abstract】 Disaster scenario is the basis of disasters simulation,and effective scenarios need to be supported by reasonable data. The most common problem of scenario generation process is:How to assure the rationality of property value.In this paper structured common knowledge model is used to represent hazard-affected bodies and properties.We also conduct the analysis of the three phenomenons producing unreasonable property value when element of hazard-affected bodies at the knowledge level are realized in practice materialized.Common knowledge model represents hazard-affected body property model and property relationship model. By analyzing constrain relationship,constrain model of properties is built Moreover,reference to representation of frame,transform constraint model to constraint equation based on frame theoretical.And finally,a case study is represented to issustrate the application of the model.
