摘　　要：由于知识图谱表示方法缺乏对动态知识的描述,且不同领域对事件的认知和描述程度具有差异性,目前暂没有事件语义模型适用于突发事件领域。因此,亟需构建一种灵活、通用、强表达力的突发事件表示模型,来刻画事件知识及规律帮助应对各类突发事件的态势风险。以通用事件模型为基础,借鉴5W1H理论方法分析突发事件构成要素及逻辑关联,提出突发事件语义模型,设计并构建融合知识图谱的多层级事件表示模型对突发事件进行表示。以突发事件融合OpenKG的城市内涝知识图谱及2000—2022年的地震数据为例,验证了模型的可行性和实施的有效性,为突发事件态势认知的研究提供有效支撑。Due to the lack of dynamic knowledge description and the difference of event cognition and description in different fields,there is no event semantic model suitable for emergencies.There-fore,it is urgent to build a flexible and general emergency representation model with strong expres-siveness to describe event knowledge to help deal with the situation risk of various emergencies.Based on the general event model,using the 5W1H theory and method for reference,this paper ana-lyzes the constituent elements and logical correlation of emergencies,puts forward the semantic mod-el of emergencies,designs and constructs a multi-level event representation model integrating knowl-edge graph to represent emergencies.Taking the urban waterlogging knowledge map of emergency fu-sion OpenKG and the seismic data from 2000 to 2022 as an example,the feasibility and implementa-tion effectiveness of the model are verified,which provides effective support for the research of emer-gency situation cognition.
