Abstract

[Purpose/Significance] Identifying and analyzing the core technology in a specific technical field can provide a comprehensive understanding of the research status and development in that field, and give suggestions for the cutting-edge technology research and acquisition.[Method/Process] It introduced a hypernetwork structure to characterize the multiple co-occurrence relationships between entities, automatically generated technology node vectors that integrate structural and attribute features with hypernetwork embedding, and obtained technology clusters through fuzzy clustering. It constructed some measures such as local neutrality, semi local centrality, and global centrality based on the hypernetwork structure to identify the core technology nodes in each technology cluster.[Result/Conclusion] Taking the field of carbon capture, utilization, and storage technology as an example, it verifies the effectiveness and scientificity of the method proposed in this article. The results show that chemical absorption, membrane separation, solid adsorption, and low-temperature separation are the core technologies in this field, which help allocate resources reasonably and improve the research of core technologies to gain competitive advantages in China.
