Construction and Application of Knowledge Graph System in Computer Science

This paper proposes a method for constructing a knowledge graph system for computer science. According to the domain knowledge collected and summarized, the data mapping model is established by analyzing the structure of the data, and the data is parsed by the stream processing method. Then, the property graph model is established according to the structure of the data to obtain the entity, the attributes of the entity and the relationship between the entities. The Neo4j graph database is also used as a storage carrier to realize the construction of the knowledge graph system in the field of computer science.
