Meadow Mari Corpus

Description

This is a text corpus of Meadow Mari language. The dataset is plain text without any additional annotations except for basic meta data which is somtetimes shifted a bit (possibly will be fixed in newer version). The genre field is in Meadow Mari, the table of contents could be found here.

Source

This corpus is a HF version of corpus by Andrei Chemyshev et al. So, if you plan on using this corpus, please cite their work:

@online{mari_monolingual_corpus,
  title={Mari monolingual corpus},
  author={Andrei Chemyshev and Gennadii Sabantsev and Nadezhda Timofeeva and Vasilii Semenov},
  year={2023},
  url={https://mari-lab.ru},
}

Composition

The corpus includes texts in various genres: prose, poetry, press, etc.

The most significant bias for this data is the dictionary data, specifically short one-sentence examples from «Марий йылме мутер» / «Словарь марийского языка» в 10 томах which is a 10 volume dictionary of Meadow Mari. That makes such examples 97.7% of the dataset entries and 6.95% of tokens.

To use this dataset as a balanced corpus, it is recommended to disable the dictionary examples. To achieve that, disable entries with мутер in genre field (it is Meadow Mari for a dictionary).
