Graph RAG for AI Applications: Building Knowledge-Aware Intelligent Systems with Graphs, Embeddings, and LLMs

This book turns hard-won patterns into repeatable frameworks. Every chapter includes runnable Python, Cypher, and API snippets, with guardrails (hop coverage, two-citation evidence, as-of dates) that make systems reliable—not just impressive demos. About the Technology Traditional RAG stalls on ambiguity, multi-hop reasoning, and governance. Graph RAG fuses knowledge graphs (entities, relations, time, authority) with vector retrieval so LLMs fetch the right context, explain their answers, and obey policy. You’ll learn to scope queries with graphs, retrieve inside that scope with hybrid ranking, and construct compact, faithful prompts. What’s Inside Architecture blueprints: context engine, session memory, caching, and eval gates Extraction & graph build: NER/RE pipelines, ontology/shape design, ingestion CI Hybrid retrieval: dense + sparse + graph priors, query planning, context ranking Faithfulness & safety: validators, evidence packs, constrained edit/abstain loops Multimodality: diagrams and tables as first-class evidence (captions & rowsets) Agents & planning: task graphs, preconditions/effects, policy-constrained execution Scaling & ops: latency budgets, snapshots/rollbacks, observability with OTel Graph-native tuning: path-conditioned prompts, lightweight LoRA adapters Who this book is for Developers & Data Scientists building production RAG features ML/Platform Engineers responsible for latency, cost, and reliability Architects & Tech Leads defining knowledge-centric AI roadmaps Researchers/Students seeking practical, evaluable techniques beyond demos LLMs alone are no longer a moat. Teams adopting knowledge-centric infrastructure are cutting tokens, raising faithfulness, and shipping features faster. If your org can’t explain why an answer is true—or roll back a bad knowledge push—you’re already behind. One bad answer can cost more than this book 100× over. These patterns reduce hallucinations, stabilize latency, and make audits trivial. Expect fewer tokens per answer, fewer incidents, and faster, safer deploys—because knowledge is versioned, measured, and portable. Build AI your stakeholders can trust.
