Construction of Scenic Spot Knowledge Graph Based on Ontology

The scenic spot knowledge graph is a kind of domain knowledge graph. This paper analyzes the construction method of domain knowledge graph, designs and implements an ontology-based scenic spot knowledge graph. According to the purpose of ontology, reusable ontology is looked for, concepts and classifications are designed, the attributes of classes are defined, and scenic spot ontology is constructed. Then, data sources are collected, and scenic spot knowledge is extracted based on ontology. A string-based and structure-based entity alignment method is designed, which aligns entity from two levels of string and entity attributes, respectively. Finally, the scenic spot knowledge graph is stored in Neo4j graph database. Experiments show that the method in this paper is feasible.
