## Definition
Knowledge Graph Integration is the process of combining structured, relational facts from a Knowledge Graph with the generative capabilities of an LLM. This provides models with access to explicit, verifiable relationship mappings, enhancing facts grounding.

## Architectural Mechanics & Deep Dive
Knowledge Graph Integration is the architecture of enriching LLM generation with structured, relationship-mapped facts from a knowledge graph. By retrieving explicit entity nodes and their relational linkages (triplets) and formatting them into the LLM prompt, the model is grounded in explicit relational facts, resolving semantic gaps in standard vector retrieval.

## Industry Applications & Real-World Use Cases
High-fidelity enterprise lookup, semantic data cataloging, and graph-based reasoning

## Frequently Asked Questions

### What is Graph RAG?
An retrieval architecture that searches a knowledge graph for related entity nodes and passes their structured relations to the LLM prompt.

### What is the main benefit over traditional vector search?
Vector search matches items based on text similarity. Graph search connects items based on explicit relationships, allowing the model to answer connection questions (e.g. "Who worked with whom?").
