Upgrade your RAG applications with the power of knowledge graphs.
Retrieval Augmented Generation (RAG) is a great way to harness the power of generative AI for information not contained in a LLM's training data and to avoid depending on LLM for factual information. However, RAG only works when you can quickly identify and supply the most relevant context to your LLM.Essential GraphRAGshows you how to use knowledge graphs to model your RAG data and deliver better performance, accuracy, traceability, and completeness.
InsideEssential GraphRAGyou'll learn:
The benefits of using Knowledge Graphs in a RAG systemHow to implement a GraphRAG system from scratchThe process of building a fully working production RAG systemConstructing knowledge graphs using LLMsEvaluating performance of a RAG pipeline
Essential GraphRAGis a practical guide to empowering LLMs with RAG. You'll learn to deliver vector similarity-based approaches to find relevant information, as well as work with semantic layers, deliver agentic RAG, and generate Cypher statements to retrieve data from a knowledge graph.
About the technology
A Retrieval Augmented Generation (RAG) system automatically selects and supplies domain-specific context to an LLM, radically improving its ability to generate accurate, hallucination-free responses. The GraphRAG pattern employs a knowledge graph to structure the RAG's input, taking advantage of existing relationships in the data to generate rich, relevant prompts.
About the book
Essential GraphRAGshows you how to build and deploy a production-quality GraphRAG system. You'll learn to extract structured knowledge from text and how to combine vector-based and graph-based retrieval methods. The book is rich in practical examples, from building a vector similarity search retrieval tool and an Agentic RAG application, to evaluating performance and accuracy, and more.
