Abstract

E-learning is an online educational system that uses electronic and technology tools and the internet. To facilitate the acquisition of knowledge, students can consult materials and interact directly with lecturers via e-learning educational systems. The method for developing an intelligent querying system for e-learning is suggested in this research. The knowledge base of the system is structured using the knowledge model combining an ontology and the two-layer knowledge graph, called Rela-KG model. The searching problems for knowledge content are studied and solved. The technique is applied to create an intelligent querying system on the course of Database Foundation in Information Technology (IT) at the university. This technique attempts to assist students in reviewing lectures and better comprehending course material through independent study. The experimental results indicate that it would be anticipated to support student access to online learning resources.
基于Rela-Ops模型和知识图谱的教育信息查询系统知识管理
电子学习是一种使用电子和技术工具以及互联网的在线教育系统。为了促进知识的获取,学生可以通过电子学习教育系统查阅材料并直接与讲师互动。本研究提出了一种用于电子学习的智能查询系统的开发方法。该系统的知识库是使用本体和两层知识图相结合的知识模型构建的,称为Rela-KG模型。研究并解决了知识内容的搜索问题。将该技术应用于高校信息技术数据库基础课程的智能查询系统中。这种技术试图帮助学生通过独立学习来复习讲座并更好地理解课程材料。实验结果表明,它有望支持学生获得在线学习资源。
