Construction of a Knowledge Representation Model in Public Health Emergencies for Information Disclosure
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.
