The WiLI benchmark dataset for written language identification
Not on the map. Why?
Abstract (arXiv)
This paper describes the WiLI-2018 benchmark dataset for monolingual written natural language identification. WiLI-2018 is a publicly available, free of charge dataset of short text extracts from Wikipedia. It contains 1000 paragraphs of 235 languages, totaling in 23500 paragraphs. WiLI is a classification dataset: Given an unknown paragraph written in one dominant language, it has to be decided which language it is.
Key facts. Cited by 8 papers in the map (data through 7 Oct 2026). First posted on arXiv 23 Jan 2018.
