Find BIS Standards
Describe your product or material. The RAG engine retrieves the top 3–5 relevant Indian Bureau of Standards specifications in seconds.
Enter a product description above to get started.
The AI will identify applicable BIS standards from the SP 21 dataset.
System Architecture
End-to-end RAG pipeline powering the recommendation engine.
PDF Ingestion
BIS SP 21 PDF is parsed using PyMuPDF / pdfplumber. Each BIS standard extracted as a discrete document preserving IS number, title, and scope.
Chunking Strategy
Hierarchical chunking — parent chunk = full standard, child chunks = individual clauses. 100-token overlap windows prevent context loss at boundaries.
Embeddings & Vector Store
Chunks encoded with SentenceTransformers or OpenAI embeddings and indexed into FAISS / ChromaDB for millisecond cosine similarity search.
Hybrid Retrieval
Dense vector retrieval fused with BM25 keyword scoring for precision on IS numbers. Hallucination guard verifies all retrieved IS numbers against index.
LLM Generation
Top-K candidates passed to Claude / GPT-4o / Mistral for re-ranking with natural language rationale. Returns top 3–5 standards with structured JSON output.
API Layer
Served via FastAPI + inference.py. Optimised for consumer hardware with <5s end-to-end latency. REST API returns ranked standards with rationale.
Evaluation Results
Performance benchmarks on public test set. All targets met or exceeded.
| Metric | Definition | Formula |
|---|---|---|
| Hit Rate @3 | ≥1 correct standard in top-3 results | (correct_queries / total) × 100 |
| MRR @5 | Mean reciprocal rank of first correct result in top-5 | Σ(1/rank_i) / N |
| Avg Latency | Average time per query end-to-end | total_time / num_queries |
| Hallucination Rate | % of responses with fabricated IS numbers | 1 − (verified / total) |
