The embodiment of the invention provides a military scientific research and production data similarity discrimination method and system based on a knowledge graph. The method comprises the steps: constructing an ontology system: constructing ontologies generating military scientific research and production data and a first incidence relation between the ontologies, and enabling the ontologies to comprise a plurality of elements; constructing a knowledge graph, including extracting entities from the original files and a second association relationship between the entities contained in each original file based on the ontology system, and generating the knowledge graph corresponding to the original files after entity alignment and association relationship reasoning, the entities being at least one of a plurality of elements of the ontology; constructing a knowledge sub-graph, including extracting and obtaining quantity information of entities of each to-be-discriminated file and quantity information of a second
