Last week, we gave a tutorial on unifying LLMs with KGs for QA at EDBT2025. This tutorial aims to furnish an overview of the state-of-the-art advances in unifying LLMs with knowledge graphs for question answering, such as KGs and text joint learning, knowledge-based instruction fine-tuning, RAG, GraphRAG, KG-RAG, Hybrid RAG, etc. The slides and other materials are now available at: https://machuangtao.github.io/LLM-KG4QA/tutorial-edbt25/
