Research on the Construction of Knowledge Graph for the Course of “Digital Electronic Technology”

在国家深化实施教育数字化战略行动，使得大规模个性化教育成为可能。而知识图谱作为人工智能新技术的知识表达形式，在智慧教育领域发挥越来越重要的作用。为此，在知识图谱的内涵研究基础上，分析了知识图谱的理论基础，构建了立体知识图谱模型，并将其应用于高等教育工科院校必修的一门重要的专业基础课程——《数字电子技术》，构建了课程的能力图谱–目标图谱–问题图谱–知识图谱的立体知识图谱，以期为学生的个性化学习提供指导。With the deepening implementation of the national digital education strategy, large-scale personalized education has become possible. As a new form of knowledge representation in artificial intelligence, knowledge graphs are playing an increasingly important role in the field of smart education. Therefore, based on the research of the connotation of knowledge graphs, this paper analyzes the theoretical basis of knowledge graphs, constructs a three-dimensional knowledge graph model, and applies it to an important professional basic course—“Digital Electronic Technology”—which is a compulsory course for engineering colleges in higher education, to build a three-dimensional knowledge graph of the course’s ability graph-goal graph-problem graph-knowledge graph, in order to provide guidance for students’ personalized learning.
