EXP-02CATEGORY: RAGSTATUS: PROTOTYPE

Enterprise Knowledge Assistant

Hybrid dense-sparse vector RAG architecture with contextual chunk re-ranking and factual grounding verification.

EXPERIMENTAL OVERVIEW & OBJECTIVE

A prototype retrieval engine that indexes enterprise documentation and returns cited, factual responses without model hallucinations.

The Research Challenge

Naive vector search often misses exact keyword nuances (part numbers, legal IDs) or retrieves out-of-context text chunks.

Engineering Approach

We combine BM25 sparse keyword search with Qdrant dense vector embeddings, passed through a cross-encoder re-ranker stage.

SYSTEM ARCHITECTURE SPECIFICATION

Hybrid Reciprocal Rank Fusion (RRF)

Contextual Document Chunking

Cross-Encoder Re-Ranking Pipeline

Citation Anchor Verification

CURRENT BENCHMARK STATE

Evaluating retrieval recall metrics on 500,000 internal engineering documents.

FUTURE ENGINEERING DIRECTION

Developing streaming multi-modal PDF table extraction modules.
