| # GLAM Extraction Benchmark — POC (silver) |
|
|
| A proof-of-concept for an open **GLAM document-extraction benchmark** (index cards + registration forms). Each item = a card/form **image** + a target **JSON Schema** + a target output JSON. |
|
|
| > **Silver labels, not a finished benchmark.** Outputs are NuExtract-3 zero-shot, reviewed/corrected by one LLM reviewer agent — **not human-verified**. NuExtract is therefore advantaged. Treat scores as illustrative; this exists to show the *shape* and seed a real, human-verified version. |
