masakhanePreprocessor

An effective language-first preprocessing tool for African languages (🔧 Beta version).

We build on the clean-text preprocessor.

How to Use

Install:

git clone https://github.com/masakhane-io/masakhanePreprocessor.git
cd masakhanePreprocessor
pip install .

Preprocessor

You only need to specify your language and it loads the important preprocessing style for You!

You initialize the Preprocessor in Python as follows:

from masakhanePreprocessor import Preprocessor

my_prep = Preprocessor(lang='ig')

You can also directly include some additional parameters you want:

my_prep = Preprocessor(lang='ig',
              lower=True,
              strip_punctuation=True,
              strip_symbols=True)

preproces_str

To preprocess a string use the preproces_str function:

clean_text = my_prep.preprocess_str('''Dịka● ndọrọndọrọọchịchị maka ntuliaka ọkwa Gọvanọ
                                       Anambra steeti si na-aga nke afọ 2021, ndị nọ.''')

You get the following as output: Dịka ndọrọndọrọọchịchị maka ntuliaka ọkwa Gọvanọ Anambra steeti si na-aga nke afọ 2021 ndị nọ

Notice how the ● character has been removed, but the -, which is an important part of Igbo, remains untouched.

preprocess_file

To preprocess a file use the preprocess_file function:

my_prep.preprocess_file('ig.txt',
                        output_path=None #Specify the output path. If unspecified, uses the parent directory of input file)

On successful completion you get this message: Clean file(s) saved successfully to xxxxxxx/ig_CLEAN.txt

Properties of the preprocessing tool

1. Language-first It can:

   • map any African language name provided to its language code. You can write Preprocessor(lang='yoruba') using just the name.
   • map any language code to its BCP47 variant. So even if you use yo or yor it does not matter.

2. Simple to use
