Survey on building knowledge graphs for aerospace manufacturing

At present, aviation equipment manufacturing enterprises have accumulated a large amount of data in the design and manufacturing-related processes. Based on the knowledge graph technology, these data can be effectively integrated and managed, and the manufacturing knowledge that is continuously updated can be mined, which will provide powerful knowledge support for the wisdom upgrade of aviation manufacturing enterprises. In order to explore the theoretical support system and practical application of knowledge graph in the field of aviation manufacturing, this paper firstly analyzed the architecture, definition and characteristics of aviation manufacturing knowledge graph through literature research. Secondly, it elucidated the core technologies in the process of constructing the knowledge graph domain and conducted a research review, then compared the similarities and differences in the construction technologies between the aerospace manufacturing knowledge graph and the general knowledge graph, and in the light of the review proposed three practical directions for the application of the aerospace manufacturing knowledge graph and its solutions. Finally, this paper stated the challenges of the future aerospace manufacturing knowledge graph and foreseen, and hoped to provide some ideas for the subsequent research in this field.
