# Dataset Card for Datause Dataset

Combined data-mention extraction dataset for the GLiNER2 data-use swarm, with
three splits: `train`, `validation`, `holdout`.

## Dataset Summary
The dataset is designed to teach Named Entity Recognition (NER) models to extract
references to datasets, databases, and surveys from PDF-extracted text.

### Splits
| split | records | notes |
|---|---|---|
| `train` | 1,779 | `v12-rerun` training split (70% positive + 120 pinned hard negatives) |
| `validation` | 415 | `v12-rerun` validation split (early stopping) |
| `holdout` | 1,149 | canonical `holdout_v10` prose-only evaluation benchmark |

## Schema (GLiNER2 Flat-NER Format)
Each record has two fields:
* `input`: The raw text paragraph containing potential data mentions.
* `output`:
    * `entities`: Dictionaries containing lists of span strings extracted for three categories:
        * `named_data`: Proper name of a dataset (e.g. `National Education Outcomes Registry (NEOR)`).
        * `descriptive_data`: Described data source (e.g. `school enrolment and retention indicators`).
        * `vague_data`: General data references (e.g. `monitoring data`).
    * `entity_descriptions`: Definitions for the three categories.

Example:
```json
{
  "input": "We use data from the Demographic and Health Surveys (DHS) 2020 and MICS 2019 to analyze child nutrition.",
  "output": {
    "entities": {
      "named_data": ["Demographic and Health Surveys (DHS)", "MICS"],
      "descriptive_data": [],
      "vague_data": ["data"]
    },
    "entity_descriptions": {
      "named_data": "A data mention with a proper name: dataset, survey, database, index, census, registry, or information system.",
      "descriptive_data": "A data mention described by its characteristics or producer rather than a proper name.",
      "vague_data": "A data mention that only generally references data, information, or statistics."
    }
  }
}
```
