EvidenT improves enterprise assistant evidence verification by 29%
EvidenT is a lightweight pipeline that verifies extracted evidence against retrieved documents before answer generation, avoiding model retraining. The authors tested it on about 500 real enterprise queries and found it raises the gold‑source hit rate by an average of 29% compared with prompting baselines. It also eliminates citations to non‑retrieved URLs and achieves near‑saturated…
Key points
- EvidenT pipeline verifies evidence before answer generation
- Improves gold‑source hit rate by 29% on 500 enterprise queries
- Eliminates citations to non‑retrieved URLs
The approach combines structured passage extraction with deterministic lexical alignment to filter unsupported content, correct citation drift, and preserve source‑span traceability. By ensuring that every answer can be traced back to a verifiable source, EvidenT addresses key reliability concerns in enterprise AI assistants.
The study demonstrates that evidence verification can be integrated into existing retrieval‑augmented generation systems without costly model retraining, offering a practical path toward more trustworthy AI in business settings.
