基于灰色关联分析的突发事件案例检索研究

Case Retrieval Based on Grey Relational Analysis

突发事件的案例检索是将案例推理技术应用于应急管理领域的关键环节。通过对案例表达结构体系的重新设计,建立了包括自然社会属性、事件属性、管理属性等三个方面的突发事件案例表达的框架体系,并进一步规范了每一类属性的描述规则以及属性的数据形态,最后应用灰色关联分析方法进行了基于案例属性的案例检索,最终的案例检索实证验证了该案例表达框架体系的合理性以及灰色关联分析的分辨力。这对于突发事件案例检索的应用以及应急管理能力的提升具有借鉴意义。

Case retrieval is a key in the application of case based reasoning（CBR）in the field of emergency management.By redesigning the structure of case expression,the paper establishes the framework system including natural attribute,event attribute and management attribute in 3 aspects of emergencies,and further standardizes every kind of attribute description rules and data attributes.Then the application of grey relational analysis method is used to match case retrieval based on the case attribute.Finally,the case study indicates that the grey relational evaluation and the case retrieval frame system is effective.It is possible to apply emergency case retrieval and improve the emergency management ability.
