 This dataset contains the collection data of the 16 "known languages". The remaining 2 "surprise languages" will not be released until later.
 
-The corpus for each language is prepared from a Wikipedia dump, where we keep only the plain text and discard images, tables, etc. Each article is segmented into multiple passages using WikiExtractor based on natural discourse units (e.g., \n\n in the wiki markup). Each of these passages comprises a "document" or unit of retrieval. We preserve the Wikipedia article title of each passage. The raw Wikipedia dump can be found [here](https://github.com/project-miracl/miracl/blob/main/README.md#corpora).
