摘要
近年来,突发公共卫生事件频发给政府应急管理带来了极大挑战.政府及时公开事件信息有助于消除公众恐慌,对于疫情防控和社会经济发展至关重要.然而,当前突发公共卫生事件信息以碎片化、不连续、不完整方式散落在不同位置,未能较好地集成融合.如何对海量、多样、变化的信息进行描述与组织是政府应急管理的关键.因此,本文面向信息公开,融合知识图谱和事理图谱,构建突发公共卫生事件知识表示模型,并对其中的核心概念及关系进行表示,提出了一种既能刻画疫情时空演化状态,又能展示疫情信息的突发公共卫生事件信息组织方法.研究结果显示,本文构建的知识表示模型具有较好的垂直性质,能够展示较为丰富的概念关系和属性特征,大部分类能够得到实例填充.本文提出的知识表示模型为突发事件知识库构建提供新思路,扩充了突发事件信息组织的方法体系,有助于存量信息公开与价值释放,进一步满足公众的信息需求,提升应急管理效果.
Abstract
In recent years,there have been frequent public health emergencies that have posed great challenges to govern-ment emergency management.The timely disclosure of event information by the government helps eliminate public panic,which is crucial for epidemic prevention and control as well as socio-economic development.However,information on public health emergencies is scattered across a variety of locations in a fragmented,discontinuous,and incomplete manner.The description and organization of such a massive,diverse,and changing body of information that is not well-integrated is thus key to government emergency management.Therefore,this study is oriented toward information disclosure and inte-grates the knowledge graph and event knowledge graph,constructs a knowledge representation model of public health emergencies,and represents the core concepts and relationships within it.It also provides a method to organize information on public health emergencies that can both represent the spatial and temporal evolution of an epidemic and display epidem-ic information.The results show that this model has good vertical properties and displays a relatively rich conceptual rela-tionship and attribute features,and most classes can be filled with examples.The knowledge representation model pro-posed in this study provides new ideas for the construction of an emergency knowledge base,thereby expanding the meth-odological system of emergency information organization.Further,it also helps in disclosing and releasing the value of stock information,satisfying the public's information needs,and improving the effectiveness of emergency management.
