Lingualytics : Easy codemixed analytics
Lingualytics is a Python library for dealing with code mixed text.
Lingualytics is powered by powerful libraries like Pytorch, Transformers, Texthero, NLTK and Scikit-learn.
Features
-
Preprocessing
- Remove stopwords
- Remove punctuations, with an option to add punctuations of your own language
- Remove words less than a character limit
-
Representation
- Find n-grams from given text
-
NLP
- Classification using PyTorch
- Train a classifier on your data to perform tasks like Sentiment Analysis
- Evaluate the classifier with metrics like accuracy, f1 score, precision and recall
- Use the trained tokenizer to tokenize text
- Some pretrained Huggingface models trained on codemixed datasets you can use
- Classification using PyTorch
Installation
Use the package manager pip to install lingualytics.
pip install lingualytics
Usage
Preprocessing
from lingualytics.preprocessing import remove_lessthan, remove_punctuation, remove_stopwords
from lingualytics.stopwords import hi_stopwords,en_stopwords
from texthero.preprocessing import remove_digits
import pandas as pd
df = pd.read_csv(
"https://github.com/lingualytics/py-lingualytics/raw/master/datasets/SAIL_2017/Processed_Data/Devanagari/validation.txt", header=None, sep='\t', names=['text','label']
)
# pd.set_option('display.max_colwidth', None)
df['clean_text'] = df['text'].pipe(remove_digits) \
.pipe(remove_punctuation) \
.pipe(remove_lessthan,length=3) \
.pipe(remove_stopwords,stopwords=en_stopwords.union(hi_stopwords))
print(df)
Classification
The train data path should have 4 files - train.txt - validation.txt - test.txt
You can just download datasets/SAIL_2017/Processed Data/Devanagari
from the Github repository to try this out.
from lingualytics.learner import Learner
learner = Learner(data_dir='<path-to-train-data>',
output_dir='<path-to-output-predictions-and-save-the-model>')
learner.fit()
Find topmost n-grams
from lingualytics.representation import get_ngrams
import pandas as pd
df = pd.read_csv(
"https://github.com/jbesomi/texthero/raw/master/dataset/bbcsport.csv"
)
ngrams = get_ngrams(df['text'],n=2)
print(ngrams[:10])
