Integration of Knowledge Graphs and Artificial Intelligence in Personalized Education: Opportunities, Challenges, and Future Directions

Abstract

With the rapid development of artificial intelligence (AI) and knowledge graphs (KGs), personalized education has emerged as a transformative approach to address the limitations of traditional one-size-fits-all teaching methodologies. Existing studies have demonstrated the potential of adaptive learning systems to enhance learner engagement, improve knowledge retention, and support diverse educational needs. However, challenges such as data sparsity, privacy concerns, and the scalability of personalized systems remain unresolved. This study systematically explores the integration of KGs and AI in personalized education, emphasizing their role in modeling complex educational relationships, providing dynamic learner profiles, and enabling intelligent recommendation systems. Through the construction of hierarchical and multi-relational KGs, combined with advanced AI techniques such as graph neural networks and explainable AI, this research highlights innovative approaches to enhance adaptability, transparency, and scalability in educational applications. Additionally, real-world case studies are presented, showcasing the synergy between AI and KGs in adaptive learning platforms and collaborative environments. This study concludes by identifying future research directions, including the development of hybrid AI-KG models and the integration of emerging technologies like large language models and immersive AR/VR systems. These findings aim to provide a robust foundation for advancing personalized education and fostering the next generation of adaptive learning technologies.
