Abstract: In recent years, knowledge graph technology has been widely used as a new method for describing concepts, entities and their relationships in the objective world. The use of knowledge graph can effectively expand the breadth of search results. At present, the keyword-based search technology adopted by the water conservancy industry is difficult to use the relationship between objects for information retrieval. To this end, this paper first proposes a knowledge graph construction method for water conservancy object data, which is used to realize the construction of water conservancy information knowledge  graph. Then, a knowledge reasoning method based on inference rules is proposed, and the knowledge hidden in  the knowledge graph of water conservancy information is used to realize intelligent data retrieval. Finally, the above technology is applied in the field of water conservancy, and the water conservancy information knowledge graph construction and retrieval system is realized. Through this system, the relationship between water conservancy objects can be effectively utilized, and the value of water conservancy information resources can be fully utilized.
