How to create a bot recognition of the user's text speech?

Question

Bots

Hello.
Are there any libraries or knowledge bases to recognize what the user is answering?
For example, when you expect a positive response from the user [Yes, Okay, Go ahead, Of course, So let's go already, ...]
For example, you want to know the user's name and he writes [My name is Vasya, Vasya is my name, Contact me Vasily, ...]
Or do you need to create such a base yourself and there is no ready-made solution?
