Characteristics Analysis of Subject Knowledge Networks of Textbooks Based on Complex Networks——Taking high school information technology subject textbooks as an example

This paper focuses on the analysis of textbooks using complex networks theory. The structure features of subject knowledge networks are examined by extracting knowledge points from the text and representing them as nodes, while the co-occurrence relationships between the knowledge points are represented as edges. Gephi and Networkx are utilized to visualize and analyze the network topology characteristics, providing objective technical support for textbook analysis. As a case study, this paper selects Chinese high school information technology subject textbooks to construct subject knowledge networks. Through a comparison and comprehensive analysis of different versions of textbooks networks, this study uncovers the differences and characteristics of various textbook versions, as well as the deep structure and internal logic of textbooks. The results demonstrate that textbook analysis based on complex networks offers many advantages, including interpretability, expressiveness, generalization, and flexibility.
