What is Natural Language Processing? 

Natural Language Processing (NLP) is a subset of artificial intelligence that enables machines to understand, interpret, and respond to human language. NLP powers tools like: 

• Chatbots (e.g., ChatGPT) 

• Voice assistants (e.g., Siri, Alexa) 

• Language translation (e.g., Google Translate) 

• Email spam filters 

• Sentiment analysis 

NLP combines linguistics, machine learning, and deep learning to analyze human language data. 

How NLP Works: A Simple Breakdown 

1. Text Preprocessing – Cleaning the data (removing stopwords, punctuation) 

1. Tokenization – Breaking sentences into words 

1. Stemming/Lemmatization – Reducing words to their root forms 

1. POS Tagging – Identifying parts of speech (noun, verb, etc.) 

1. Named Entity Recognition (NER) – Identifying people, places, brands 

1. Sentiment Analysis – Understanding emotions behind the text
