# gliner2_datause

Fine-tune of `fastino/gliner2-large-v1` (GLiNER2) for data-use mention extraction
(dataset / survey / census / registry mentions in economics research papers).

## Labels
- `NAMED_DATA` — a proper name, title, or acronym of a specific data source
- `DESCRIPTIVE_DATA` — a source described in words but not named
- `VAGUE_DATA` — generic data wording with no identifiable source

## Training
- base model: `fastino/gliner2-large-v1`
- dataset: `rafmacalaba/data-use-mentions` (gliner2 config)
- epochs: 5
- encoder LR: 1e-05
- task LR: 0.0005
- batch size: 8
- precision: bf16
