Abstract

The invention discloses a knowledge graph construction system and method based on a graph database, and the method comprises the steps: recognizing the types of graph data in the graph database, and loading the different types of graph data into a CPU memory in batches; identifying the graph data loaded into the CPU memory one by one, marking a result attribute association field to obtain a fieldof a knowledge graph, and extracting an information field; establishing a data dimension inner-layer model for the information fields according to the proportion, and establishing a data dimension outer-layer model based on the data dimension inner-layer model; according to the data dimension inner-layer model and the data dimension outer-layer model, data in the models being subjected to persistence, and obtaining a knowledge graph database; and establishing a knowledge query Web interface, analyzing the query command, and returning to the knowledge graph database to retrieve result data. According to the invention, one-key query and millisecond response are realized, the difficulty of knowledge mining of graph data is reduced as much as possible, and the efficiency of knowledge graph construction is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of knowledge map construction, and more specifically, the present invention relates to a knowledge map construction system and method based on a graph database. Background technique [0002] The knowledge map is a combination of theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with metrology citation analysis, co-occurrence analysis and other methods, and uses the visual map to vividly display the core structure and development of the subject. History, frontier fields, and the overall knowledge structure achieve the modern theory of multidisciplinary integration. It displays complex knowledge fields through data mining, information processing, knowledge measurement and graphic drawing, reveals the dynamic development law of knowledge fields, and provides practical and valuable references for subject research. In sc...
