-# GraphRAG-Live
-
-**Hybrid Retrieval-Augmented Generation (RAG) with Graph + Vectors.**
-
-This project shows how knowledge graphs (Neo4j Aura) and vector databases (Qdrant) can be combined with re-ranking heuristics to build a smarter, cheaper and more explainable RAG system.
-
----
-
-## 🌟 Features
-- **Hybrid Retrieval:** Combines semantic search (Qdrant) with graph proximity scoring (Neo4j).  
-- **Dynamic Knowledge Injection:** Add new documents on the fly → pipeline updates instantly.  
-- **Evidence Subgraphs:** Each answer includes a small 2-hop evidence graph.  
-- **Metrics Dashboard:** Compare GraphRAG vs. baseline RAG on hit@10, nDCG@10, citation correctness.  
-- **Hosted Demo:** Deployed via Hugging Face Spaces (Gradio UI).
