摘　　要：教育知识图谱作为知识的可视化呈现,通过处理海量无序、结构繁杂的数据,使其形成结构化的知识体系,在教育领域不断挖掘出新的发展空间。通过系统性文献综述,系统梳理了国内近10年的实证研究成果,以揭示知识图谱在教育领域的具体类型、应用及面临的挑战。研究发现,教育知识图谱主要包括学科知识图谱、群体知识图谱、多模态知识图谱、学习认知地图及教育知识库5种类型;知识图谱在学习者画像构建、学情诊断及学习评价、学习资源推荐、个性化学习路径规划、智能化管理及知识问答系统5个方面应用广泛。此外,在现阶段教育知识图谱构建及应用过程中,仍存在教育资源数据集质量不高、多源知识图谱融合难度大、教育知识图谱评估方法单一的实践挑战。As a visual representation of knowledge,educational knowledge graph forms a structured knowledge system by processing massive disordered and complicated data,and constantly excavates new development space in the field of education.Through systematic literature re⁃view,systematically comb the empirical research results of the past 10 years in China to reveal the specific types,applications and challenges of knowledge map in the field of education.The research found that the educational knowledge map mainly includes five types:subject knowl⁃edge map,group knowledge map,multimodal knowledge map,learning cognitive map and educational knowledge base;Knowledge atlas is widely used in five aspects:learner portrait construction,learning situation diagnosis and learning evaluation,learning resource recommenda⁃tion,personalized learning path planning,intelligent management and knowledge question and answer system.In addition,in the construction and application process of education knowledge map at the current stage,there are still practical challenges such as low quality of education re⁃source data sets,difficult integration of multi-source knowledge map,and single evaluation method of education knowledge map.
