Looking for hot words in a sentence?

Question

Python

Hello everyone who reads this.
I am writing my bot in python, and now I am faced with a new problem. He can only respond to commands like: write a movie, he will show the schedule in the cinema. But if I write show the schedule in the cinema, he will not understand me. I want to do a hot word search. For example, if the input sentence contains the word cinema , it will show the schedule. If there is a word currency it will show the exchange rate. Tell me how to do it?
PS I myself tried using conditional expressions, but this does not suit me, since the bot will still not understand synonyms. And this is just what I need.
PPS You don't need to write ready-made code, just tell me which library can help me.

Answer 2

spacy
