Install

pip install fasttext-langdetect-wheel

Usage

detect method expects UTF-8 data. low_memory option enables getting predictions with the compressed version of the fasttext model by sacrificing the accuracy a bit.

from ftlangdetect import detect

result = detect(text="Bugün hava çok güzel", low_memory=False)
print(result)
> {'lang': 'tr', 'score': 1.00}

result = detect(text="Bugün hava çok güzel", low_memory=True)
print(result)
> {'lang': 'tr', 'score': 0.9982126951217651}

Benchmark

We benchmarked the fasttext model against cld2, langid, and langdetect on Wili-2018 dataset.

• pop weighted means recall for each language is multipled by its number of speakers.
• 139 languages = all languages with ISO 639-1 2-letter code
• 44 languages = top 44 languages spoken in the world

Recall per language
