Measurement system service function recommendation method based on mapping knowledge domain

The invention discloses a measurement system business function recommendation method based on a knowledge graph, and the method comprises the steps: S1, obtaining a historical access file record of a user, carrying out the preprocessing, and importing the historical access file record into the knowledge graph; s2, forming a sub-graph based on a knowledge graph topological relation; s3, on the basis of a hierarchical attention model, modeling is carried out in the sub-atlas, model parameters are trained, and a trained recommendation model is obtained; and S4, deploying the trained recommendation model, and intelligently pushing related data of a service corresponding to a role to a user by using the recommendation model based on a fault real-time monitoring condition and real-time access data states of other users when the service personnel user accesses the system. By implementing the method, the complexity of the algorithm can be reduced, and the reliability and the recommendation accuracy can be improved. 本
