To improve the efficiency of knowledge map construction,a method of knowledge map build-ing based on dynamic ontology is proposed to increase the flexibility and compatibility of map construc-tion according to the advantages of the dynamic body update.Firstly,a hierarchical ontology concep-tual model with mutually independent subclasses is designed through synchronously defined dynamic ontology method.Secondly,by the matching algorithm combining the sound code and character similar-ity,new ontology models are generated by merging similar ontology classes and building non-similar ontology class based on the existing model.The ontology model is used as the upper logic map struc-tured data to generate diagram data content.Finally,the ontology update algorithm is used to update the existing chip industry chain model to the body model of the automotive industry chain,so as to verify the feasibility of the algorithm.Further,it is combined with instance data to be stored in the Neo4j diagram database for visual display.
