# Dataset Card

This dataset is created from the English Wikipedia dump file (enwiki-20240901-pages-articles-multistream.xml.bz2), available for download from [Wikimedia Dumps](https://dumps.wikimedia.org/). It includes pages containing mathematical content, extracted using [the wikimathextractor tool](https://github.com/s-kat0/wikimathextractor), which is an adaptation of [the wikiextractor](https://github.com/attardi/wikiextractor) specifically designed to extract mathematical contents.


### Dataset Description

- **Curated by:** Shota Kato
- **Language(s) (NLP):** English
- **License:** CC-BY-SA 4.0


### Dataset Sources

- **Repository:** [s-kat0/wikimathextractor](https://github.com/s-kat0/wikimathextractor)
- **Data Source:** [Wikipedia Dumps](https://dumps.wikimedia.org/)


### Direct Use

This dataset is intended for use in tasks that require the processing and understanding of mathematical content in natural language, such as mathematical question answering and symbolic math problem solving.


## Dataset Structure

### Data Instances

A typical data entry in the dataset corresponds to one Wikipedia article that includes mathematical content. Here is an example:

```python
{
  'id': '26513034',
  'title': 'Pythagorean theorem',
  'text': 'Relation between sides of a right triangle\nIn mathematics, the Pythagorean theorem or Pythagoras\' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. ...'
  'formulas': [
    {'math_id': 0, 'text': 'a^2 + b^2 = c^2 .'},
    {'math_id': 1, 'text': 'a + b'}, ...
  ],
  'url': 'https://en.wikipedia.org/wiki?curid=26513034'
}
```

### Data Fields

- id (str)
    - a string representing the unique identifier of the article.
- title (str)
    - the title of the Wikipedia article.
- text (str)
    - the text content of the article, with some tags removed. Details are available in [the GitHub repository](https://github.com/s-kat0/wikimathextractor).
- formulas (list[dict[str, int | str]])
    - a list of mathematical expressions extracted from the article, where each formula is represented as follow.
        - math_id: an index representing the position of the formula in the text.
        - text: the textual representation of the formula, without <math> tags.
- url (str)
    - the URL of the Wikipedia article.


### Data Splits

The dataset is provided in a single training split:

- train: 38,661 rows

The `DatasetDict` structure is as follows:

```python
DatasetDict({
    'train': Dataset({
        features: ['id', 'title', 'text', 'formulas', 'url'],
        num_rows: 38661
    })
})
```
