Dataset Card for Wikimedia Wikisource

Dataset Summary

Wikisource dataset containing cleaned articles of all languages.

The dataset is built from the Wikisource dumps (https://dumps.wikimedia.org/) with one subset per language, each containing a single train split.

Each example contains the content of one full Wikisource text with cleaning to strip markdown and unwanted sections (references, etc.).

All language subsets have already been processed for recent dump, and you can load them by date and language like this:

from datasets import load_dataset

ds = load_dataset("wikimedia/wikisource", "20231201.en")

Supported Tasks and Leaderboards

The dataset is generally used for Language Modeling.
