Southborough death cards — structured extraction

Handwritten death-record index cards from the Southborough (MA) Town Clerk collection (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

gold/silver: image_id · image · extraction (JSON). pool: image_id · image.
