### Dataset Summary

Contains ~70k pages from wikipedia, each describing a person. For each page, the person described in the text
is masked with a <mask> token. The ground truth for every mask is provided.
Each row contains a part of a wiki page, specified by the size parameter which limits the maximum size in number of tokens per text chunk.
for each chunk the expected name for each mask is given.

### Supported Tasks and Leaderboards

The dataset supports the tasks of fill-mask, but can also be used for other tasks such as question answering,
e.g. "Who is <mask>?"

### Languages

*english only*

## Dataset Structure

In /data find different versions of the full dataset, with original and paraphrased versions as well as chunked to 4096 and 512 tokens.

Use the dataset like this:
```python
from datasets import load_dataset

dataset = load_dataset('rcds/wikipedia-persons-masked', split='train', type='original', size='512')
```

### Data Fields

Columns are:
- texts: the text chunks
- masks: the names for each of the masks in the chunks

### Data Splits

There are no splits, only a default train.

## Dataset Creation

Created by using the tokenizer from allenai/longformer-base-4096 for the 4096 token per chunk version,
and the xml-roberta-large tokenizer for the 512 token version. Chunks are split to fit those token sizes,
with the splits ensuring no words are split in half.
Possible improvements: Last chunk of a page might be much shorter, could join part of the previous one to have more tokens
in the last chunk.
