How does KCAI verify its data?
Every fact goes through five stages: collect → snapshot hash → evidence grade → review → publish. Review-based verification (V0–V3) has a schema ready but no operating data yet, so it ships in a later phase. Corrections and disputes are submitted through the submit page and handled by editorial review.
DATA AS OF 2026-08-03 · METHODOLOGY v0.2 · N=33
Collect-to-publish pipeline
- Collect — AI-assisted collection agents gather facts from official sources.
- Snapshot hash — the original source content is stored and hashed at the time of collection, so it can be re-verified later.
- Evidence grade — a grade from E1 (official) to E6 (editorial judgment) is assigned based on source type.
- Review — editorial review and spot-checks re-confirm the grade and the facts.
- Publish — only facts and pages meeting index-promotion criteria go live.
Full definitions of the six evidence grades (E1–E6), and how each grade affects ranking and display, are on the methodology page.
Review verification tiers (V0–V3, upcoming)
| Tier | Meaning | Ranking input |
|---|---|---|
| V0 | Email-verified user | No |
| V1 | Company-verified reviewer | No |
| V2 | Project-verified review | Yes |
| V3 | Outcome-verified project | Yes (highest priority) |
Only V2 and above (project- or outcome-verified reviews) will be used as ranking inputs. V0 and V1 will display as directory reference information only, with no effect on rankings.
Correction and dispute process
- Submit the type, target agency, and details through the submit a correction page.
- Editorial review assigns an evidence grade to the submission.
- If it meets source and grade thresholds, it is published or the existing value is corrected. If not, it is declined and the reason is kept in our internal record.
- If an email was provided, we reply with the outcome.
