How to Use the Package

1. Basic Text Preprocessing

Lowercasing Text

import nlp_text_preprocessing as tp

text = "HELLO WORLD!"
processed_text = tp.to_lower_case(text)
print(processed_text)  # Output: hello world!

Expanding Contractions

import nlp_text_preprocessing as tp

text = "I'm learning NLP."
processed_text = tp.contraction_to_expansion(text)
print(processed_text)  # Output: I am learning NLP.

Removing Emails

import nlp_text_preprocessing as tp

text = "Contact me at [e-mail]"
processed_text = tp.remove_emails(text)
print(processed_text)  # Output: Contact me at 

Removing URLs

import nlp_text_preprocessing as tp

text = "Check out https://example.com"
processed_text = tp.remove_urls(text)
print(processed_text)  # Output: Check out

Removing HTML Tags

import nlp_text_preprocessing as tp

text = "<p>Hello World!</p>"
processed_text = tp.remove_html_tags(text)
print(processed_text)  # Output: Hello World!

Removing Special Characters

import nlp_text_preprocessing as tp

text = "Hello @World! #NLP"
processed_text = tp.remove_special_chars(text)
print(processed_text)  # Output: Hello World NLP

2. Advanced Text Processing

Lemmatization

import nlp_text_preprocessing as tp

text = "running runs"
processed_text = tp.lemmatize(text)
print(processed_text)  # Output: run run

Sentiment Analysis

import nlp_text_preprocessing as tp

text = "I love programming!"
sentiment = tp.sentiment_analysis(text)
print(sentiment)  # Output: Sentiment(polarity=0.5, subjectivity=0.6)

Detecting and Translating Language

import nlp_text_preprocessing as tp
from googletrans import Translator

translator = Translator()
text = "Bonjour tout le monde"
lang = tp.detect_language(text, translator)
translated_text = tp.translate(text, 'en', translator)
print(f"Language: {lang}, Translated: {translated_text}")
# Output: Language: fr, Translated: Hello everyone

3. Feature Extraction

Word Count

import nlp_text_preprocessing as tp

text = "I love NLP."
count = tp.word_count(text)
print(count)  # Output: 3

Character Count

import nlp_text_preprocessing as tp

text = "I love NLP."
count = tp.char_count(text)
print(count)  # Output: 9

N-Grams

import nlp_text_preprocessing as tp

text = "I love NLP"
ngrams = tp.n_grams(text, n=2)
print(ngrams)  # Output: [('I', 'love'), ('love', 'NLP')]

4. Full Example: Cleaning Text

Here’s an example of how you might use several functions together to clean text data:

import nlp_text_preprocessing as tp

text = "I'm loving this NLP tutorial! Contact me at https://www.linkedin.com/in/uditya-narayan-tiwari-562332289/  Visit https://udityanarayantiwari.netlify.app/"
cleaned_text = tp.clean_text(text)
print(cleaned_text)
# Output: i am loving this nlp tutorial contact me at visit

One Short Feature Extraction

import nlp_text_preprocessing as tp

tp.extract_features("I love NLP")

Notes

• Be cautious when using heavy operations like lemmatize and spelling_correction on very large datasets, as they can be time-consuming.
• The package supports custom cleaning and preprocessing pipelines by using these modular functions together.
