Document Q&A Pipeline with Retrieval-Augmented Generation (RAG)
Build an end-to-end knowledge assistant that parses engineering documentation, creates semantic vector embeddings, and performs grounded retrieval with source attribution.
Recommended Tech Stack
Key Skills You Demonstrate
- ✓Semantic text chunking strategies (recursive, semantic, windowing)
- ✓Vector database indexing and top-K similarity search
- ✓Prompt engineering for grounded answers without hallucination
- ✓Evaluating retrieval quality with precision and faithfulness metrics
Core Features to Implement
Do not use giant chunk sizes. Optimal retrieval typically uses 250-500 token chunks with 50-token overlaps.
- →Add a reranker model (like Cohere or BGE Reranker) to refine top-K candidates before prompting
