Weekend Project: Benchmarking GraphRAG vs. VectorRAG Multi-hop Retrieval
kmeanskaran · x · 2026-08-08
A developer shared a weekend baseline benchmarking GraphRAG (multi-hop retrieval) vs. VectorRAG, detailing a workflow built entirely with open-source tools:
- Data Preparation: Curated a Marathi dataset focusing on agriculture and government schemes.
- Graph Construction: Designed LLM-based SVO (Subject-Verb-Object) generation and ingested the data into Neo4j.
- Experiments: Tested one-hop and two-hop query scenarios.
- Evaluation Metrics: Ran evaluations on a gold Q&A dataset, focusing on metrics like hallucination rate and relevancy scores.
