Knowledge Graph RAG

Learn everything you need to know to combine Generative AI and knowledge graphs to produce highly accurate responses, with rich context and deep explainability.

1Knowledge graph fundamentals

Knowledge graphs provide the foundation for representing complex relationships that traditional databases can't effectively handle.

2Building knowledge graphs

Learn how to combine structured and unstructured data to create a knowledge graph.

4Evaluating GraphRAG

Learn how to evaluate the performance of your GraphRAG applications and understand the metrics that matter.

Yes, but what is GraphRAG?

GraphRAG (Graph Retrieval-Augmented Generation) is the union of Generative AI (GenAI) and Knowledge Graphs. In GraphRAG, a knowledge graph provides contextual facts and relationships that ground a Large Language Model (LLM), helping to prevent hallucinations and produce more accurate answers.

On this page you'll learn what is GraphRAG and why it matters, and discover how to build knowledge graphs from unstructured data and assemble end-to-end GraphRAG pipelines using Neo4j's GenAI tools. Our step-by-step learning path covers everything from LLM basics to advanced RAG workflows, with pointers to free GraphAcademy courses that teach each topic.

GraphRAG (Graph Retrieval-Augmented Generation) is the union of Generative AI (GenAI) and Knowledge Graphs. In GraphRAG, a knowledge graph provides contextual facts and relationships that ground a Large Language Model (LLM), helping to prevent hallucinations and produce more accurate answers.

Why context matters

Traditional RAG often misses relationships between entities. GraphRAG leverages the connected nature of knowledge graphs to provide more contextual and accurate answers.

More accurate responses to complex queries that require understanding relationships

Why relationships are key

Flat data representations miss complex relationships between entities. GraphRAG enables sophisticated reasoning by understanding how entities relate to each other.

Build applications that understand how people, concepts, and data interconnect in meaningful ways

Why explainability is important

Black-box AI responses lack transparency. GraphRAG lets you trace reasoning through knowledge graphs, providing clear evidence for AI-generated responses.

Build trust in AI systems by providing clear reasoning paths for every response
