## What is Intent Recognition

Intent Classification is one of the core tasks in the field of Natural Language Processing (NLP), aiming to understand the real purpose or intent behind the text input by users. It is a fundamental component of modern dialogue systems, chatbots, and intelligent customer service.

## Simple Examples

When a user says:
- "What's the weather like in Beijing tomorrow?" → Intent: Query Weather
- "Help me book a flight to Shanghai" → Intent: Book Flight
- "This song is really nice" → Intent: Express Emotion
- "How to return or exchange goods?" → Intent: After-sales Inquiry

Intent recognition maps open natural language to predefined intent categories, enabling machines to "understand" what the user wants to do.

## Why It Matters

In dialogue systems, accurately recognizing user intent is a prerequisite for correct responses:
- Incorrect intent → Response deviates from user needs
- Correct intent → Provide precise service

It is a bridge connecting natural language and system functions.
