## Dataset Structure

### Data Instances

#### claims

- **Size of downloaded dataset files:** 3.12 MB
- **Size of the generated dataset:** 262.61 kB
- **Total amount of disk used:** 3.38 MB

An example of 'validation' looks as follows.
```
{
    "cited_doc_ids": [14717500],
    "claim": "1,000 genomes project enables mapping of genetic sequence variation consisting of rare variants with larger penetrance effects than common variants.",
    "evidence_doc_id": "14717500",
    "evidence_label": "SUPPORT",
    "evidence_sentences": [2, 5],
    "id": 3
}
```

#### corpus

- **Size of downloaded dataset files:** 3.12 MB
- **Size of the generated dataset:** 7.99 MB
- **Total amount of disk used:** 11.11 MB

An example of 'train' looks as follows.
```
This example was too long and was cropped:

{
    "abstract": "[\"Alterations of the architecture of cerebral white matter in the developing human brain can affect cortical development and res...",
    "doc_id": 4983,
    "structured": false,
    "title": "Microstructural development of human newborn cerebral white matter assessed in vivo by diffusion tensor magnetic resonance imaging."
}
```

### Data Fields

The data fields are the same among all splits.

#### claims
- `id`: a `int32` feature.
- `claim`: a `string` feature.
- `evidence_doc_id`: a `string` feature.
- `evidence_label`: a `string` feature.
- `evidence_sentences`: a `list` of `int32` features.
- `cited_doc_ids`: a `list` of `int32` features.

#### corpus
- `doc_id`: a `int32` feature.
- `title`: a `string` feature.
- `abstract`: a `list` of `string` features.
- `structured`: a `bool` feature.
