Match review
Cross-source pairs for a person to decide. The answers are the ground truth any automatic matcher is scored against.
Items
Products from different sources — are these the same product?
| Stratum | Pairs | Answered | Same | Different | Unsure |
|---|---|---|---|---|---|
| control | 300 | 0 | 0 | 0 | 0 |
| likely | 600 | 0 | 0 | 0 | 0 |
| near | 900 | 0 | 0 | 0 | 0 |
| upc-agree | 300 | 0 | 0 | 0 | 0 |
| upc-conflict | 500 | 0 | 0 | 0 | 0 |
Highlighted rows are the audits: a control pair answered “same” (expected different) or a shared-UPC pair answered “different”. Score the strata separately — one blended “% same” hides exactly these.
Outlets

| name-city | 600 | 0 | 0 | 0 | 0 |
