Graph RAG Explained - Extracting Knowledge Graph from Unstructured Data

Ever wondered how AI can understand relationships instead of just retrieving text? In this video, we dive deep into Microsoft Graph RAG — a cutting‑edge approach that transforms unstructured documents into a connected knowledge graph for smarter, context‑aware answers. This video introduces the concept of Graph RAG, demonstrating how to build a custom system for unstructured data. We explore the different stages involved in processing data for graph-based retrieval augmented generation, including various search modes like local, global, and drift search, offering a practical ai tutorial for data science enthusiasts. This approach leverages a knowledge graph to enhance llm rag systems. 🤩 Complete article: https://shweta-lodha.medium.com/how-i-built-a-microsoft-graph-rag-system-that-turns-unstructured-text-into-connected-intelligence-134af9b54d42 You’ll learn: 🔹 What Graph RAG is and how it differs from traditional RAG 🔹 How Microsoft Graph RAG processes data step‑by‑step — from text chunking to graph construction 🔹 How GPT‑4o extracts entities and relationships 🔹 How communities and summaries are generated for multi‑hop reasoning 🔹 How embeddings and LanceDB enable fast, semantic search 🔹 How queries return LLM‑grounded answers with citations Whether you’re building AI systems, exploring retrieval‑augmented generation, or just curious about how Graph RAG connects data like humans do, this video breaks it all down visually and practically. 🧠 Keywords Graph RAG, Microsoft Graph RAG, Retrieval Augmented Generation, Knowledge Graph, GPT‑4o, LanceDB, AI Search, Entity Extraction, Graph Database, Semantic Search, LLM Architecture, Azure AI, AI Reasoning, Multi‑Hop Retrieval 🔗 Timestamps 0:00 – What is Graph RAG 0:30 – What use cases it covers 1:10 – How Graph RAG works? 2:35 – Different stages in Graph RAG 5:57 - Graph Rag use case 8:37 - Graph RAG Configuration 21:18 – Search modes in Graph RAG 36:00 Why to use Graph RAG 📌You can support me here: https://www.buymeacoffee.com/shwetalodha 🎉 ................
