Research on knowledge graph construction method for emergency response of hazardous chemicals accident
In order to transform the complex knowledge in emergency standards of hazardous chemicals into the structured and visualized forms,so as to improve the speed of accidental emergency response and decision-making efficiency,this paper re-searches on the knowledge graph construction method for hazardous chemical accident and emergency response.Based on the top-down approach,the framework of emergency response ontology model for hazardous chemical accidents was established.The construction method for the data layer of knowledge graph was designed by integrating the machine learning model and knowledge fusion algorithm,and the experimental validation and construction of the knowledge graph were conducted by using the current emergency standards as the corpus.The results show that based on the method proposed in this paper,the high-level digitization of hazardous chemicals emergency standards can be realized.The research results can provide a new perspec-tive for the emergency management knowledge organization.
