## Dataset Structure

### Data Instances

## Identification

```
{
    "tokens": ["It", "’s", "a", "curious", "thing", ",", "the", "death", "of", "a", "loved", "one", "."]
    "start_index": 11
    "end_index": 12
    "label": 1
}
```

## Resolution

```
{
    "tokens": ["I", "'m", "eighty", "tomorrow", ".", "Are", "you", "sure", "?"],
    "line_indices": [0, 0, 0, 0, 0, 1, 1, 1, 1],
    "head": ["AGE"],
    "speakers": ["John Doe", "John Doe", "John Doe", "John Doe", "John Doe", "Joe Bloggs", "Joe Bloggs", "Joe Bloggs", "Joe Bloggs"],
    "anchors_indices": [2]
}
```

### Data Fields

## Identification

- `tokens` - List of token strings as tokenized with [Spacy](spacy.io).
- `start_index` - Start index of the anchor.
- `end_index` - End index of the anchor.
- `label` - "pos" or "neg" depending on whether this example contains a numeric fused head.

## Resolution

- `tokens` - List of token strings as tokenized with [Spacy](spacy.io)
- `line_indices` - List of indices indicating line number (one for each token)
- `head` -  Reference to the missing head. If the head exists elsewhere in the sentence this is given as a token index.
- `speakers` - List of speaker names (one for each token)
- `anchors_indices` - Index to indicate which token is the anchor (the visible number)
