Description

technical field

[0001] The invention belongs to the technical field of primary and secondary education knowledge graph analysis, and in particular relates to a primary and secondary education knowledge graph analysis system based on co-word and co-citation analysis. Background technique

[0002] The "knowledge map" is based on the CNKI full-text database of Chinese periodicals, using the "subject" retrieval method, selecting the keyword "primary and middle school teacher education", setting the time node as a node in the past to the present, and selecting the source category as "core periodicals" and "CSSCI", after reasonable screening, a total of 233 valid documents were obtained, which were used as the sample object. Based on the retrieved effective data, the clustering analysis tool CitespaceⅤ is used to combine qualitative and quantitative data to conduct statistical analysis and visual processing of samples from multiple dimensions. The size of the node ring in the map ...
