# gliner-datause-displacement-withnonmention

Fine-tune of `urchade/gliner_large-v2.1` for data-use mention extraction with a
**single `DATA_MENTION` class**, trained on
[`rafmacalaba/data-use-mentions-tiered`](https://huggingface.co/datasets/rafmacalaba/data-use-mentions-tiered)
— the tiered copy of `rafmacalaba/data-use-mentions` where Luna/classifier-judged
T3 (non-mention) and junk spans are **untagged hard negatives** (text stays,
span removed). The extractor owns the mention boundary only (T1 evidential ∪
T2 declaration vs T3/junk); specificity detail is recovered downstream by the
multitask SFT model.

## Labels
- `DATA_MENTION` — a real data mention that carries an analytic or
  declarative use (T1 evidential ∪ T2 declaration)

## Training
- base model: `urchade/gliner_large-v2.1`
- dataset: `rafmacalaba/datause-displacement-reviewed` (gliner_reviewed_nm config)
- epochs: 5
- learning rate: 5e-06
- batch size: 16
- precision: bf16
- checkpoint selection: **val span-F0.5** (post-hoc sweep of epoch
  checkpoints; eval_loss was explicitly not used)

## Evaluation (tiered holdout)

Gold = T1∪T2 spans; a true-FP cluster matching a dropped T3/junk span
counts as a **T3 leak** (lower is better). Label-agnostic Hungarian
matching, jaccard >= 0.5 — identical to prior data-use-mentions evals.
