Abstract

This paper presents a knowledge graph-enhanced recommendation system, inspired by constructivist principles, to address challenges like information overload and fragmented knowledge in online education. The system transforms unstructured information into interconnected knowledge frameworks, facilitating semantic comprehension, personalized recommendations, and cognitive feedback. Aligned with constructivist principles, the platform encourages students to actively construct personalized knowledge structures, enhancing cognitive engagement through adaptive feedback. Experiments with higher education students demonstrate its potential to improve learning interest, knowledge retention, and adaptive feedback, supporting advanced semantic and cognitive learning paradigms.

知识图谱增强了在线学习中语义结构构建和反馈的推荐

本文提出了一种基于建构主义原理的知识图增强推荐系统，以解决在线教育中信息过载和知识碎片化等问题。该系统将非结构化信息转换为相互关联的知识框架，促进语义理解、个性化推荐和认知反馈。该平台与建构主义原则相一致，鼓励学生积极构建个性化的知识结构，通过自适应反馈增强认知参与。在高等教育学生中进行的实验表明，它有可能提高学习兴趣、知识保留和自适应反馈，支持先进的语义和认知学习范式。
