In response to the small scale and semi-structure characteristics of the knowledge data of water conservancy projects,a knowledge graph construction approach for the semi-structured water conservancy project data based on multi-plex regular matching method is proposed.It includes various steps such as data cleaning,text similarity calculation,ex-traction rule formulation,and multiplex regular matching.Taking the semi-structured data of the water conservancy pro-jects in Anhui Province as an example,entities and relationships of water conservancy projects are extracted.The results show that the proposed method improves the performance indicator F1 value by about 16%compared to existing methods.
