Natural Language Processing
AI is technology that enables computers and machines to simulate human learning.
What is NLP?
Natural Language Processing (NLP) is a branch of Artificial Intelligence that helps computers understand, interpret, and use human language (spoken or written).
👉 In short: NLP is how computers talk with us in our own language.
Easy Example
- When you ask Google: “What’s the weather today?” ☁️
- Google doesn’t understand English directly.
- NLP converts your words → into data → processes it → gives back an answer in English.
How NLP Works (Step by Step)
- Input: You type or speak something (e.g., “Play music”).
- Processing:
- Breaks your sentence into words.
- Understands grammar and meaning.
- Figures out your intention.
- Output: Computer gives a response (e.g., starts playing music 🎵).
Real-Life Applications of NLP
- Voice Assistants → Alexa, Siri, Google Assistant 🎙️
- Chatbots → customer support on websites 💬
- Translation → Google Translate 🌍
- Text Prediction → keyboards suggesting words ✍️
- Sentiment Analysis → companies checking if reviews are positive/negative 🙂☹️
- Search Engines → Google understanding your queries 🔍
Easy Analogy
- Without NLP: Talking to a foreigner who doesn’t understand your language.
- With NLP: Having a translator who makes both sides understand each other.
In short:
NLP = The technology that helps computers understand and respond to human language.
