UltraNLP - Ultra-Fast NLP Preprocessing Library

🚀 The fastest and most comprehensive NLP preprocessing solution that solves all tokenization and text cleaning problems in one place

🤔 The Problem with Current NLP Libraries

If you've worked with NLP preprocessing, you've probably faced these frustrating issues:

❌ Multiple Library Chaos

The old way - importing multiple libraries for basic preprocessing

import nltk import spacy import re import string from bs4 import BeautifulSoup from textblob import TextBlob

❌ Poor Tokenization

Current libraries struggle with modern text patterns:

• NLTK: Can't handle $20, 20Rs, [e-mail] properly
• spaCy: Struggles with emoji-text combinations like awesome😊text
• TextBlob: Poor performance on hashtags, mentions, and currency patterns
• All libraries: Fail to recognize complex patterns like [e-mail], #hashtag, @mentions as single tokens

❌ Slow Performance

• NLTK: Extremely slow on large datasets
• spaCy: Heavy and resource-intensive for simple preprocessing
• TextBlob: Not optimized for batch processing
• All libraries: No built-in parallel processing for large-scale data

❌ Incomplete Preprocessing

No single library handles all these tasks efficiently:

• HTML tag removal
• URL cleaning
• Email detection
• Currency recognition ($20, ₹100, 20USD)
• Social media content (#hashtags, @mentions)
• Emoji handling
• Spelling correction
• Normalization

❌ Complex Setup

Typical preprocessing pipeline with multiple libraries

def preprocess_text(text):

Step 1: HTML removal

from bs4 import BeautifulSoup text = BeautifulSoup(text, "html.parser").get_text()

Step 2: URL removal

import re text = re.sub(r'https?://\S+', '', text)

Step 3: Lowercase

text = text.lower()

Step 4: Remove emojis

import emoji text = emoji.replace_emoji(text, replace='')

Step 5: Tokenization

import nltk tokens = nltk.word_tokenize(text)

Step 6: Remove punctuation

import string tokens = [t for t in tokens if t not in string.punctuation]

Step 7: Spelling correction

from textblob import TextBlob corrected = [str(TextBlob(word).correct()) for word in tokens]

return corrected
