RAG pipelines when your source data is messy

RAG fails quietly: plausible answers with wrong citations, stale content, duplicates that confuse retrieval, and “knowledge” that was never meant for customer-facing answers. If your sources are messy, the pipeline must include hygiene, metrics, and freshness as first-class engineering work.

Chunking and deduping

• Chunk by semantic boundaries—not arbitrary token counts alone.
• Deduplicate near-identical documents; otherwise retrieval oscillates.

Freshness and ownership

Assign owners to source collections with SLAs for updates—especially pricing, policies, and product specs.

Signal	What it tells you
Retrieval hit rate	Are you finding the right docs?
Grounding score	Are answers supported by sources?
User corrections	Where the system is confidently wrong

Operational loop

Ship weekly eval runs. Treat regressions like production incidents—because for customers, they are.

DigiiMark designs retrieval metrics and content hygiene loops you can trust—so “AI search” does not become “AI guess.”
