Knowledge Graph construction of Thangka icon characters based on Neo4j

Thangka is a kind of Tibetan painting art, Thangka knowledge is too fragmentary, lacks integrated information generalization, and users have too few ways to understand it. In order to popularize users’ knowledge of Thangka and better manage the retrieval of thangka knowledge service mode, this paper proposes the construction of the knowledge graph of Thangka graph icon characters based on Neo4j. Through constructing the Schema layer of Thangka knowledge in a top-down way, designing the data layer of Thangka knowledge graph in a bottom-up way, and using Neo4j graph database to store the data of knowledge graph. The construction of the knowledge graph of thangka icon characters can serve as the foundation for the future information retrieval, visual display and the application of knowledge questions.
