Abstract: 【Purpose/significance】This paper discusses the structure model construction and implementation of knowledge graph for
LMA digital service convergence【. Method/process】This paper combs the research and application status of the knowledge graph in the field of LMA,studies the construction method of the knowledge graph,firstly constructs the structure model of the knowledge graph of LMA,and then designs the construction process of the knowledge graph,including the demand analysis,data acquisition,knowledge ex-traction,knowledge convergence,storage design and mapping knowledge graph.Finally,taking the Xinhai Revolution theme as an exam-ple,the storage mode of the knowledge graph is designed,and the Neo4j is applied to the database stores and implements the subject knowledge graph of LMA【. Result/conclusion】The LMA knowledge graph can cross the knowledge barrier of a single field and fuse the LMA resources.It can also visually display the semantic association between the LMA digital resources,facilitate users' knowledge ac-quisition and knowledge discovery【. Innovation/limitation】This paper research enriches the application scenarios of knowledge graph,and provide a new way of knowledge visualization and service for LMA digital services convergence.
