| 中文摘要: |
| 为实现对突发事件演化态势的推演及问题的分解，针对已有突发事件态势研究中缺乏与推理规则结合的问题，借鉴基于知识元的事物知识表示方法，提出突发事件问题域知识组织的事件对象-属性-关系层次模型．通过将模型关系层中推理规则由基本结构转换为最简结构，得到两个事物属性间最简洁的关联结构．连接推理规则最简结构，构建可用于表示突发事件问题域发展态势及实现问题分解的特征网络．最后，通过震后物资调度的案例验证了特征网络对突发事件态势描述的可行性． |
| 英文摘要: |
| To actualize the development state of emergency and problem decomposition, aiming at solving the problem of lacking combination with reasoning rules in the state of emergency, in view of the knowledge representation method based on knowledge unit, the object-attribute-relation hierarchical model for knowledge organization in emergency problem domain is proposed. Through conversing the basic structure to the briefest structure of reasoning rules in model relation-layer, the briefest relation between two things′ attributes is obtained. By connecting the briefest structure of reasoning rules, the feature network is constructed which can represent the development state of emergency problem domain and achieve problem decomposition. Finally, the feasibility of the feature network to describe the state of emergency is proved through a material-dispatching case after the earthquake. |
