摘要
知识图谱提供了一种高效描述概念及其联系的工具,借助本体在语义层次上描述特定领域的知识,形成共享概念模型的形式化规范说明。文章提出了一种基于知识图谱的在线教学方法,从概念和性质出发,分析知识间的层级隶属关系,基于概念和性质构建分层有序的结构化知识本体;基于知识图谱建立认知系统思维结构,改进教学方法,重构教学体系。教学实践结果表明,知识图谱能够清晰明了地展示知识间的内在联系,分层次有序表达知识体系,有助于学生形成对知识的准确认知,进而有效提高在线教学的质量。
Knowledge graph provides a tool to efficiently describe concepts and their connections.It describes the knowledge of a specific field at the semantic level with the help of ontology and forms a formal specification of the shared conceptual model.This paper proposes an online teaching method based on knowledge graph,analyzes the hierarchical subordination between knowledge,constructs a hierarchical and orderly structured knowledge ontology based on concepts and properties,establishes the thinking structure of cognitive system,improves the teaching method and constructs the teaching system.The results of teaching practice show that the knowledge graph can clearly show the internal connection between knowledge,express the knowledge system in and orderly,help students to form an accurate cognition of knowledge,and effectively improve the quality of online teaching.
