How NELL Avoids Hallucination

The mechanisms behind every NELL report: sourced claims with deep-link citations, the figures we refuse to fabricate, and how we label confidence.

How NELL avoids hallucination

Every report is built under rules about what may be claimed and what must be left blank. A missing number is a correct answer; an invented one is a defect.

• Claims carry a source and a deep link, and are labelled by confidence rather than asserted flat.
• NELL refuses to fabricate specific categories outright — pricing it has not seen, headcounts, funding it cannot source, and quotes.
• Where evidence is thin the report says so and marks the gap instead of filling it.
• Counts shown to a user come from records the product actually holds, not from a model’s estimate.
