The invention relates to the technical field of knowledge maps, can be applied to an intelligent traffic operation management scene, and discloses an
intelligent decision-making method, device, equipment and medium based on a semantic knowledge map, and the method comprises the steps: carrying out the analysis, cleaning and
complementation of multi-source heterogeneous data, and generating a standardized event flow under a unified space-time reference; constructing a semantic
knowledge graph containing entities, attributes, relationships and
business logic, injecting the standardized event streams into the graph to complete
pattern matching, generating a structured knowledge packet and realizing
business logic updating; and
scene analysis is carried out based on the structured knowledge packet and the semantic
knowledge graph, an analysis result is output, a decision suggestion is generated, and closed-loop
processing from data to decision is realized. According to the method, multi-
source data is converted into structured knowledge and semantic reasoning is introduced, so that the analysis result can support decision generation, and the semantic understanding ability and decision support efficiency of data fusion are improved.
