Abstract: Social learning platforms provide a dynamic interactive and individualised learning experience as artificial intelligence in education is increasingly used. Though they have data privacy and AI security issues, these services gather a great amount user data. Releasing user data such as voice calls, text messages, social connections, and learning preferences could cause privacy issues. This paper presents FL-KGPrivacyEdu, a federated knowledge graph model combining federated learning (FL) and knowledge graph (KG) to address the problem of behavioural modelling and privacy preservation in social English learning. The methodology examines social learning across platforms and terminals while safeguarding data. Experimental validation demonstrates that the model is successful and superior in social English learning behaviour analysis in accuracy, recall, and F1 score. This study also looks at how model convergence, a major model training reference, is affected by learning rate modification in worldwide rounds.
Keywords: federated learning; FL; knowledge graph; KG; federated knowledge graph; data privacy protection; AI security.
