Multilingual RAG Quality Evaluation & Feedback Loops

Measure and improve multilingual RAG with locale-aware metrics, human reviews, and continuous feedback to boost grounded answers.

Multilingual RAG must stay grounded across locales. Robust evaluation—automatic and human—plus feedback loops on retrieval and generation improve accuracy, reduce hallucinations, and respect locale policies.

Content gap detection and corpus curation per locale.

Locale/legal safety checks; PII/secret filters; rights filters.

Refusal policies for low-grounding or missing citations.

Human review queue for low-confidence/critical items.

Telemetry + user signals linked to retrieval/docs.

Frequently asked questions

What is the purpose of creating locale-specific gold sets and setting metrics?

Create locale-specific gold sets; set metrics and guardrails.

How can offline evaluations be conducted and the LLM judge calibrated?

Run offline evals; calibrate LLM-judge; ?

How should user feedback be collected and used to analyze failures?

Wire user feedback; build failure analytics; tune rewrites/rerankers.

How can content gaps be addressed and freshness monitoring implemented?

Close content gaps; add freshness monito?; enforce citations/refusals.
