1๏ธโฃ What is a Chatbot?
A chatbot is an AI program that can talk to humans, answer questions, and hold conversations.
- โ๏ธ Rule-Based Chatbots โ Follow pre-written scripts (e.g., customer support bots).
- โ๏ธ AI-Powered Chatbots โ Use machine learning & NLP to improve responses (e.g., ChatGPT, Siri).
2๏ธโฃ How Do Chatbots Work? ๐ ๏ธ
A chatbot follows three main steps:
- 1๏ธโฃ User Input: The user types a message.
- 2๏ธโฃ Processing: The chatbot understands the input (NLP).
- 3๏ธโฃ Response: The bot replies with a relevant answer.
Example: User: “Whatโs the weather today?” โ Bot: “Itโs sunny and 75ยฐF โ๏ธ”
