Survey: GraphRAG and Knowledge Graphs for Large Language Models

The seminal paper “Unifying Large Language Models and Knowledge Graphs: A Roadmap” published on June 14, 2023, presents a comprehensive framework for integrating the emergent capabilities of Large Language Models (LLMs) with the structured knowledge representation of Knowledge Graphs (KGs)  Authored by Shirui Pan, Linhao Luo, Yufei Wang, Chen Chen, Jiapu Wang, and Xindong Wu, the paper outlines three general frameworks for this unification: KG-enhanced LLMs, LLM-augmented KGs, and Synergized LLMs + KGs. These frameworks aim to leverage the strengths of both LLMs and KGs to enhance AI’s inferential and interpretative abilities, address the construction and evolution challenges of KGs, and promote bidirectional reasoning driven by data and knowledge. The paper’s roadmap is a forward-looking guide that reviews existing efforts and pinpoints future research directions, marking a pivotal contribution to the field of natural language processing and artificial intelligence.
