Abstract: Cypher language is widely applied in knowledge graph querying.However,it exhibits inherent limitations:insufficient semantic support in specific-domain scenarios and cumbersome expression of complex queries,which are unfavorable for the design of query engines.By analyzing the characteristics of clinical diagnosis and treatment query application based on medical record knowledge graph,a query meta operation for medical record(MR) knowledge graph and a query application semantic model generated by the combination of these meta operations are designed.Combined into a hierarchical semantic model,these meta-ope-rations provide a clear and structured way to represent clinical queries.This model serves as an effective logical-layer abstraction for query engines,leveraging a production rule system to efficiently convert queries into Cypher execution plans.The rules define direct mappings from the model's constructs to Cypher syntax,enabling automatic translation of high-level query intentions into executable statements.Experiments show that this semantic model performs well in terms of expressiveness and accuracy for queryapplications oriented to the medical record knowledge graph,as well as in the operational robustness of the query engine built on it.

Key words: Medical record knowledge graph, Meta-operation, Query semantic model, Cypher language
