[Objective] This paper aims to study medical semantic association with the help of complex network. [Methods] First, we constructed a medical semantic association network using the medical semantic concepts as nodes and semantic associations as edges. Then, we analyzed the network characteristics and semantic community. Finally, we created vectors for the semantic concepts and conducted semantic clustering analysis with the neural network. [Results] We retrieved relevant literature on “coronavirus” from MEDLINE of PubMed and built a semantic association network with 43 nodes and 877 edges. Then, we visualized the network characteristics, semantic community and semantic clusters. [Limitations] The experimental data size needs to be expanded. [Conclusions] The proposed network effectively describes the semantic association among medical concepts and benefits medical knowledge discovery services.
