Tetun LID

Tetun Language Identification (Tetun LID) model is a machine learning model that automatically identifies the language of a given text. It was specifically designed to recognize four languages commonly spoken in Timor-Leste: Tetun, Portuguese, English, and Indonesian.

Installation

With pip:

pip install tetun-lid joblib scikit-learn

Usage

The examples of its usage are as follows:

1. To predict the language of an input text, use the predict_language() function.

from tetunlid import lid

input_text = "Sé mak toba iha ne'ebá?"
output = lid.predict_language(input_text)

print(output)

This will be the output. (Note: The initial call may take a few minutes to complete as it will load the LID model.)

Tetun

2. To print the details of the Probability of being predicted to Tetun use the predict_detail() function.

from tetunlid import lid

input_list_of_str = ["Sé mak toba iha ne'ebá?"]
output_detail = lid.predict_detail(input_list_of_str)
print('\n'.join(output_detail))

This will be the output:

Input text: "Sé mak toba iha ne'ebá?"
Probability:
        English: 0.0010
        Indonesian: 0.0014
        Portuguese: 0.0082
        Tetun: 0.9967

3. We can feed a mixed of corpus containing multiple languages into the LID model as the input list. Observe the following example:

from tetunlid import lid

multiple_langs = ["Ha'u ema baibain", "I am not available",
                  "Apa kabar kawan?", "Estou a estudar"]

output = [(ml, lid.predict_language(ml)) for ml in multiple_langs]
print(output)

This will be the output:

[("Ha'u ema baibain", 'Tetun'), ('I am not available', 'English'), ('Apa kabar kawan?', 'Indonesian'), ('Estou a estudar', 'Portuguese')]

You can use print the output in the console as follows:

from tetunlid import lid
import warnings
warnings.filterwarnings('ignore')

input_texts = ["Ha'u ema baibain", "I am not available",
                "Apa kabar kawan?", "Estou a estudar"]

for input_text in input_texts:
    lang = lid.predict_language(input_text)
    print(f"{input_text} ({lang})")

This will be the output:

Ha'u ema baibain (Tetun)
I am not available (English)
Apa kabar kawan? (Indonesian)
Estou a estudar (Portuguese)

To print the details of each input, use the same function as previously explained. Here is the example:

from tetunlid import lid
import warnings
warnings.filterwarnings('ignore')

input_texts = ["Ha'u ema baibain", "I am not available",
                "Apa kabar kawan?", "Estou a estudar"]

output_multiple_details = lid.predict_detail(input_texts)
print('\n'.join(output_multiple_details))

This will be the output:

Input text: "Ha'u ema baibain"
Probability:
        English: 0.0032
        Indonesian: 0.0032
        Portuguese: 0.0028
        Tetun: 0.9907

Input text: "I am not available"
Probability:
        English: 0.9999
        Indonesian: 0.00001
        Portuguese: 0.00001
        Tetun: 0.00001

Input text: "Apa kabar kawan?"
Probability:
        English: 0.0011
        Indonesian: 0.9961
        Portuguese: 0.0015
        Tetun: 0.0184

Input text: "Estou a estudar"
Probability:
        English: 0.0003
        Indonesian: 0.002
        Portuguese: 0.9810
        Tetun: 0.0184

4. We can filter only Tetun text from a mixed of corpus containing multiple languages using the predict_language() function.

from tetunlid import lid
import warnings
warnings.filterwarnings('ignore')


input_texts = ["Ha'u ema baibain", "I am not available",
                "Apa kabar kawan?", "Estou a estudar"]

output = [text for text in input_texts if lid.predict_language(text) == 'Tetun']
print(output)

This will be the output:

["Ha'u ema baibain"]

Additional notes

1. If you encountered an AttributeError: 'list' object has no attribute 'predict_proba', you might have some issues while installing the package. Please send me an email, and I will guide you on how to handle the error.
2. Please make sure that you use the latest version of Tetun LID by running this command in your console: pip install --upgrade tetun-lid.
