Knowledge graph, as an intelligent and efficient way for knowledge organization, enables users to quickly and accurately query the information they need. In this paper, we provide a comprehensive survey on the development and construction of knowledge graph by reviewing and summarizing recent advances in the research and practice of knowledge graph systems in the relevant literature. In particular, our introduction includes the concept origin, development, and eventual formation of the knowledge graph, various data sources for the knowledge graph, the ontology construction and the entity extraction, and the process of knowledge mining, updating, and maintenance. Finally, we discuss the technical challenges, development trends, and future research directions of knowledge graph. In summary, the theory and the associated techniques of knowledge graph is of great research significance. However, there are still many technical challenges, which need further investigation, in building and using the knowledge graph.
