  This article introduces the Wanca 2017 corpus of texts crawled from the
internet from which the sentences in rare Uralic languages for the use of the
Uralic Language Identification (ULI) 2020 shared task were collected. We
describe the ULI dataset and how it was constructed using the Wanca 2017 corpus
and texts in different languages from the Leipzig corpora collection. We also
provide baseline language identification experiments conducted using the ULI
2020 dataset.
