The datasets are built from the Wikipedia dump (https://dumps.wikimedia.org/) with one split per language. Each example contains the content of one full Wikipedia article with cleaning to strip markdown and unwanted sections (references, etc.). The articles are parsed using the ``mwparserfromhell`` tool. To load this dataset you need to install Apache Beam and ``mwparserfromhell`` first: ``` pip install apache_beam mwparserfromhell ``` Then, you can load any subset of Wikipedia per language and per date this way: ```python from datasets import load_dataset load_dataset("wikipedia", language="sw", date="20220120", beam_runner=...) ``` where you can pass as `beam_runner` any Apache Beam supported runner for (distributed) data processing (see [here](https://beam.apache.org/documentation/runners/capability-matrix/)). Pass "DirectRunner" to run it on your machine. You can find the full list of languages and dates [here](https://dumps.wikimedia.org/backup-index.html). Some subsets of Wikipedia have already been processed by HuggingFace, and you can load them just with: ```python from datasets import load_dataset load_dataset("wikipedia", "20220301.en") ``` The list of pre-processed subsets is: - "20220301.de" - "20220301.en" - "20220301.fr" - "20220301.frr" - "20220301.it" - "20220301.simple" ### Supported Tasks and Leaderboards The dataset is generally used for Language Modeling. ### Languages You can find the list of languages [here](https://meta.wikimedia.org/wiki/List_of_Wikipedias). ## Dataset Structure ### Data Instances An example looks as follows: ``` {'id': '1', 'url': 'https://simple.wikipedia.org/wiki/April', 'title': 'April', 'text': 'April is the fourth month...' } ``` Some subsets of Wikipedia have already been processed by HuggingFace, as you can see below: #### 20220301.de - **Size of downloaded dataset files:** 6.84 GB - **Size of the generated dataset:** 9.34 GB - **Total amount of disk used:** 16.18 GB #### 20220301.en - **Size of downloaded dataset files:** 21.60 GB - **Size of the generated dataset:** 21.26 GB - **Total amount of disk used:** 42.86 GB #### 20220301.fr - **Size of downloaded dataset files:** 5.87 GB - **Size of the generated dataset:** 7.73 GB - **Total amount of disk used:** 13.61 GB #### 20220301.frr - **Size of downloaded dataset files:** 13.04 MB - **Size of the generated dataset:** 9.57 MB - **Total amount of disk used:** 22.62 MB #### 20220301.it - **Size of downloaded dataset files:** 3.69 GB - **Size of the generated dataset:** 4.76 GB - **Total amount of disk used:** 8.45 GB #### 20220301.simple - **Size of downloaded dataset files:** 251.32 MB - **Size of the generated dataset:** 246.49 MB - **Total amount of disk used:** 497.82 MB ### Data Fields The data fields are the same among all configurations: - `id` (`str`): ID of the article. - `url` (`str`): URL of the article. - `title` (`str`): Title of the article. - `text` (`str`): Text content of the article. ### Data Splits Here are the number of examples for several configurations: | name | train | |-----------------|--------:| | 20220301.de | 2665357 | | 20220301.en | 6458670 | | 20220301.fr | 2402095 | | 20220301.frr | 15199 | | 20220301.it | 1743035 | | 20220301.simple | 205328 | ## Dataset Creation ### Curation Rationale [More Information Needed](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards) ### Source Data #### Initial Data Collection and Normalization [More Information Needed](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards) #### Who are the source language producers?
