# fastlangid
[](https://codecov.io/gh/currentsapi/fastlangid) [](https://badge.fury.io/py/fastlangid)
The only language identification that includes Cantonese (廣東話), traditional and simplified Chinese.
## Why and who is this package for?
This is a language identification language focus on providing higher accuracy in Japanese, Korean, and Chinese language compares to the original Fasttext model ( lid.176.ftz ). This package also include identification for cantonese, simplified and traditional Chinese language.
First stage model F1, which is same from fasttext language identification model
| Model | F1@1 |
|-----------------------|--------|
| lid.176.ftz | 0.977 |
We can achieve higher accuracy by including an additional language identification model to handle low confidence scores for Japanese, Korean, Chinese. The table below shows F1 (k=1) scores in identifying 3 languages. (we updated the validation corpus which is much harder to the first revision : shorter text, latest news text )
| 2nd-Stage Model | F1@1 | Acc@1 |
|-----------------------|--------|--------|
| version 1.0.0 | 0.826 | 0.744 |
| master | 0.801 | 0.894 |
Master version is also trained with identifying Cantonese (zh-yue) text from Mozilla Common Voice corpus text. Currently the model is senstive to non cantonese text mixing inside the sentence, hence please use the model with care.
To use Cantonese prediction, it recommended to force inference using the second stage prediction
```
lang_code = langid.predict('平嘢有冇好嘢?', force_second=True)
```
For more edge case detail please refer to [fasttext_issues.py](tests/fasttext_issues.py)
The training data for the supplement model was drawn from Common Crawl Corpus and [Currents API](https://currentsapi.services/en) internal language dataset.
We wish to support Cantonese language in the upcoming future. Feel free to contact us if you would like to provide any related corpus.
## Install
```bash
$ pip install fastlangid
```
## Example
Only one function call away to handle single or multiple sentences
```
from fastlangid.langid import LID
langid = LID()
result = langid.predict('This is a test')
print(result)
```
```
from fastlangid.langid import LID
langid = LID()
examples = [
'中文繁體',
'中文简体',
'Lorem Ipsum is simply dummy text of the printing and typesetting industry',
'Lorem Ipsum adalah text contoh digunakan didalam industri pencetakan dan typesetting',
'Le Lorem Ipsum est simplement du faux texte employé dans la composition et la mise en page avant impression'
]
results = langid.predict(examples)
print(results)
```
## Supported Languages
Supports 177 languages. The ISO codes for the corresponding languages are as below.

## Caveats
Bag of words method doesn't work well in short text classification as found by [this article by Apple](https://machinelearning.apple.com/research/language-identification-from-very-short-strings). Hence it's recommend that you ensure the text have at least more than 5 characters/words.
Cantonese language identification is trained on daily conversation text which may not represent well in article types text. Hence it may confuse with traditional chinese (zh-hant) as they share the exact same characters.
