GraphRAG, a combination of knowledge graphs and retrieval-augmented generation (RAG), has evolved into various techniques with a growing body of research papers and software integrations. The second GenAI Graph Gathering brought together experts to discuss the progress and challenges in using knowledge graphs for retrieval, observing that applications often start with unstructured or structured data but typically stall in the pilot phase. A pattern catalog was curated to distill information from research papers, and proven approaches were implemented in tools and libraries to help address the "cold start" problem and provide guidance on domain-specific GraphRAG approaches. The discussion also covered knowledge graph construction, visualization, and ontology development, highlighting the importance of schemas for interoperability, explainability, and grounding. Advanced graph retrieval techniques, such as contextual retrieval, query-focused summarization, and GNNs, were explored, emphasizing the need for case-dependent approaches. Ultimately, GraphRAG continues to evolve with a focus on cross-organ collaboration, successful individual outcomes, and benefiting from the collective knowledge and technologies.
