# Southborough death cards — structured extraction

Handwritten **death-record index cards** from the Southborough (MA) Town Clerk collection
([`biglam/index-cards-southborough-vital-records`](https://huggingface.co/datasets/biglam/index-cards-southborough-vital-records)),
prepared for schema-conditioned extraction. Each card records a death: `name`, `date_of_death`,
`place_of_death`, `place_of_burial`, `sex`, `condition`, `cause_of_death`, `age`, `occupation`,
`birthplace` (+ volume/page).

| config | cards | labels |
|---|---|---|
| `eval` | 12 | **AI-labelled, not human-verified** — a Claude agent read each card image carefully (one at a time, flagging uncertain readings). Held out for evaluation. *Higher-quality model labels, but not gold.* |
| `silver` | 127 | **machine-generated** labels (Qwen3-VL-8B, bulk from the image) — SFT data, *not* hand-verified |
| `pool` | 160 | **unlabelled** image pool — re-label with your own model/schema |

Training (`silver`) and evaluation (`eval`) data for the [index-card-extractor-4b](#) research model;
`pool` is the unlabelled source for `silver`.

> ⚠️ **No human-verified ground truth here.** Both `eval` and `silver` are model-generated (the `eval`
> set more carefully, by a stronger model). Evaluation numbers against `eval` are *relative to agent
> labels*, not gold. Free-text fields (names, places) carry model noise.

## Columns
