An interview with an AI chatbot

Hello everyone! Today, we're going to talk to an AI chatbot called D-Thinker. Many of you want to know how chatbots work, so let's ask D-Thinker some questions.
Welcome to our programme, D-Thinker! Our first question is: How did you become an AI chatbot?
Reporter
Thank you for having me! Well, I have many "parents" in my "family" — Y Tech Company. They created me. Let me explain how I was "born":
Step 1: ______
My "parents" first collected a large number of texts from the internet. They used books, articles, and websites to help me learn how people use language in different ways.
Step 2: ______
Next, they cleaned the data (数据) by taking out private details and then organised it for training.
Step 3: ______
Then, they used a special computer program to teach me. This program looked at how words and sentences are put together and I learned how to write like a human. They used very powerful computers to make the model.
Step 4: ______
After that, my "family" taught me to do some tasks, such as answering questions and chatting with people.
Step 5: ______
Finally, they put me on apps and websites so that people can chat with me.
My main job is to read your messages and then reply according to what I've learned. I don't have feelings or thoughts like humans, but I can help with information or talk with you about many topics. If you have more questions, just ask!
