In recent years, knowledge graph technology has developed rapidly, and the value of domain knowledge graphs has been recognized. Experts in various fields have conducted extensive research on the construction of knowledge graphs, and have successfully applied them to services such as knowledge retrieval, question and answer, and knowledge recommendation. Taking oil and gas pipeline safety accident data as the main data source, relevant information is extracted through conceptual model design, knowledge extraction, and other steps. It is integrated with the original structured data. With the help of the Neo4j graph database, a pipeline safety system integrating oil and gas pipeline safety accident data and relevant regulations is constructed. The knowledge graph in the accident field enables the storage and visualization of oil and gas pipeline safety information.
