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
- Text Preprocessing – Cleaning the data (removing stopwords, punctuation)
- Tokenization – Breaking sentences into words
- Stemming/Lemmatization – Reducing words to their root forms
- POS Tagging – Identifying parts of speech (noun, verb, etc.)
- Named Entity Recognition (NER) – Identifying people, places, brands
- Sentiment Analysis – Understanding emotions behind the text
