The paper provides a comprehensive overview of GraphRAG, a framework that leverages structural information in databases to improve the accuracy and context-awareness of large language models. It formalizes the GraphRAG workflow and outlines core technologies and training methods.

The survey also examines downstream tasks, application domains, evaluation methodologies, and industrial use cases.
