Module 5: Natural Language Processing (NLP) Basics

Introduction to NLP

Natural Language Processing (NLP) is a field of artificial intelligence (AI) that enables machines to understand, interpret, and generate human language. It bridges the gap between human communication and machine intelligence, allowing computers to process large volumes of text and speech data efficiently.

Key Components of NLP:

  • Tokenization: Breaking text into words or sentences.
  • Stopword Removal: Filtering out common words like “the,” “is,” and “and.”
  • Stemming & Lemmatization: Reducing words to their root forms.
  • Part-of-Speech (POS) Tagging: Identifying grammatical categories of words.
  • Named Entity Recognition (NER): Extracting names, locations, and other key entities.
  • Syntax & Semantic Analysis: Understanding sentence structure and meaning.

How AI Understands Text & Speech

AI understands language through a combination of linguistic rules and machine learning models. The process involves several stages:

  1. Text Preprocessing: Cleaning text data by removing noise, punctuation, and irrelevant words.
  2. Feature Extraction: Converting words into numerical representations like word embeddings (Word2Vec, GloVe, BERT).
  3. Machine Learning Models: Using models like Naïve Bayes, Support Vector Machines (SVM), and deep learning architectures such as transformers to analyze language.
  4. Speech Recognition: Converting spoken words into text using Automatic Speech Recognition (ASR) systems like Google Speech-to-Text and Whisper.

NLP Applications

NLP is widely used across industries to enhance automation, improve communication, and extract insights from textual data. Some key applications include:

1. Chatbots & Virtual Assistants

  • AI-powered assistants like Siri, Alexa, and Google Assistant use NLP to understand and respond to user queries.
  • Chatbots in customer service improve response times and enhance user experiences.

2. Sentiment Analysis

  • Businesses analyze customer feedback and social media sentiment to understand public opinion.
  • NLP models classify text as positive, negative, or neutral to gauge sentiment trends.

3. Machine Translation

  • Tools like Google Translate and DeepL use NLP to translate text between languages.
  • Advanced models like Transformer-based neural networks enhance translation accuracy.

4. Text Summarization

  • NLP algorithms condense long documents into concise summaries.
  • Extractive and abstractive summarization techniques help in information retrieval.

5. Speech-to-Text & Text-to-Speech

  • Used in transcription services, accessibility tools, and virtual assistants.
  • Deep learning models improve speech recognition accuracy.

Hands-on NLP with Python

Python provides powerful libraries for NLP that enable quick experimentation and implementation of models.

1. Installing Required Libraries

pip install nltk spacy transformers

2. Basic Text Processing with NLTK

import nltk
from nltk.tokenize import word_tokenize
nltk.download('punkt')

text = "Natural Language Processing is fascinating!"
tokens = word_tokenize(text)
print(tokens)

3. Named Entity Recognition with spaCy

import spacy
nlp = spacy.load("en_core_web_sm")

doc = nlp("Elon Musk founded SpaceX in 2002.")
for ent in doc.ents:
    print(ent.text, ent.label_)

4. Sentiment Analysis with Transformers (BERT)

from transformers import pipeline

classifier = pipeline("sentiment-analysis")
result = classifier("I love Natural Language Processing!")
print(result)

Conclusion

NLP is a rapidly evolving field with vast applications in AI-driven technologies. By mastering NLP basics, you can build intelligent systems that understand and generate human-like text, paving the way for advanced AI solutions in various domains.
