Ontology Construction of Knowledge Graph for Early Warning Equipment Maintenance and Support Field

In response to the reality of massive, multi-source, and unsystematic data on early warning equipment maintenance and support, in order to improve the utilization rate of early warning equipment maintenance and support resources and enhance maintenance and support efficiency, a top-down approach is adopted to propose a knowledge graph ontology construction method for early warning equipment maintenance and support, providing model support for the construction of knowledge graphs in this field.
