| description | A construction method of an urban traffic knowledge graph comprises the following steps: firstly, constructing an urban traffic ontology by using an ontology construction tool by adopting a seven-step method published by Steafu University to form a knowledge graph mode layer; then acquiring and fusing urban traffic multi-source data, extracting entities, attributes and relationships among the entities, and constructing a knowledge graph data layer; the knowledge graph mode layer and the knowledge graph data layer are combined to generate an urban traffic knowledge graph, and the urban traffic knowledge graph is stored in a database; and inferring new knowledge of urban traffic by using the existing data, and supplementing the new knowledge into an urban traffic knowledge graph. The method is used for solving the current situation that the traffic data opening and sharing degree is not high, multi-source data are fused, an urban traffic knowledge system is built, and the method can also be applied to predictin |
