Source-aware retrieval

A retrieval strategy in rag (Retrieval-Augmented Generation) that utilizes document provenance and metadata to improve accuracy beyond simple Embeddings similarity.

Key Implementation: LangExtract

• Uses a Gemini-powered information extraction library to enable enhanced rag through precise metadata matching.
• Addresses fundamental flaws in traditional rag systems where vector-database chunks lack context, specifically:
  • Document versioning conflicts.
  • Discrepancies between different source documents.
