Abstract In recent years, there have been frequent public health emergencies that have posed great challenges to government 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 integrates 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 epidemic information. The results show that this model has good vertical properties and displays a relatively rich conceptual relationship and attribute features, and most classes can be filled with examples. The knowledge representation model proposed in this study provides new ideas for the construction of an emergency knowledge base, thereby expanding the methodological 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.
