China's space industry is thriving and space technology is world class. Driven by digitization of resources and use of knowledge mapping tools, deep mining and demonstration of spacecraft data was carried out, and spacecraft data resources were constructed into shared stereoscopic digital resources.Taking open spacecraft data as the research object, using deep learning model to extract information, using Protege to construct spacecraft ontology, combining Neo4j database to construct spacecraft knowledge map.The spacecraft knowledge graph can improve the digital reuse of spacecraft data resources, at the same time, it can also use the spacecraft knowledge graph to query the data, which can realize the digital and intelligent development of spacecraft data resources in the future, and further promote the development and innovation of the aerospace field.
