#625 gold-set adjudication packet — org-name-grain over-merged clusters (GBT, shipped config)

TX --max-npis 300 · 816 records · generated by nppes-dedup-benchmark --dump-overmerges

For each cluster: the matcher fused records that the org-name truth says belong to DIFFERENT entities. Adjudicate each: [same] one real-world entity (yardstick error — the truth under-collapsed) or [distinct] genuinely different co-located providers (modelneural classifierThe machine learning model at the core of Mailwoman's parser — a transformer encoder (~30M parameters) trained from scratch to do BIO token classification over addresses. It learns the 'grammar' of address formats; the gazetteer supplies the 'atlas.' over-merge). Mark inline and return.

Cluster 1 — 9 records, 9 org-name entities → verdict: [same] — Nine serial NPI registrations of ONE company — identical name, address, official, taxonomy. Textbook yardstick error (the practice-address-keyed truth never unions them because their TX practice sites differ; these are the shared back-office records).​

Adjudication summary (Claude, 2026-07-06 — operator-delegated)​

14/21 clusters are [same] (yardstick error) · 7/21 are [distinct] (genuine over-merge).

Method: each cluster judged on the full record evidence — org-name identity (incl. dba/acronym/rename relationships expressed IN the records, e.g. a single NPI carrying both names), authorized official, taxonomy, and address roles (practice site vs corporate/billing). Where a cluster's records express only a corporate identity (cluster 8), the verdict follows what the records say, with the granularity caveat noted inline.

Findings:

  1. Two-thirds of the residual "over-merge" is the yardstick, not the modelneural classifierThe machine learning model at the core of Mailwoman's parser — a transformer encoder (~30M parameters) trained from scratch to do BIO token classification over addresses. It learns the 'grammar' of address formats; the gazetteer supplies the 'atlas.'. With 14 of 21 clusters adjudicated same-entity, the genuine over-merged-cluster count drops 21 → 7 — the matcher's true org-grain quality is materially above the measured 68.8% F1 (consistent with the ~1.6% irreducible-ceiling estimate).
  2. The genuine over-merge class has ONE signature: the management-company roll-up. All 7 [distinct] clusters are differently-branded operating entities sharing a corporate/billing address — and in most, the AUTHORIZED OFFICIAL also agrees (the roll-up operator signs everything). The auth-official discriminator is actively harmful on exactly this class: it corroborates the wrong merge.
  3. The next lever writes itself: when org names disagree strongly and the ONLY agreements are address + official, that pattern is management-company evidence, not identity evidence — a corroboration rule (or a GBTGBT (Gradient Boosted Trees). A non-linear machine learning model that combines many weak decision trees into a strong predictor. Mailwoman uses a GBT as an optional learned scorer for single-dataset dedup, improving F1 by 5–7 percentage points over the Fellegi-Sunter baseline. featurefeatureAn input signal a model conditions on. Beyond the raw tokens, Mailwoman feeds soft features — gazetteer-membership channels and the postcode anchor — that inform predictions without overriding them.: official-agree × org-disagree × address-shared) targeting precisely the 7 remaining clusters. Filed on #625.
