What PHP AI Libraries or Frameworks Are There? Which ones are suitable for text analysis?

Question

PHP

There are letters.
Depending on the text of the letter, you need to send a response from the list of responses.
Now the analysis is done by keywords (tags) in the letter.
We need to see a smarter implementation.
In this regard, two questions:
1. What even exists with a hint of AI for PHP?
2. Which of these can be "fastened" to the task?

Answer 1

Try this https://github.com/teamtnt/tutorials/blob/master/t...
If it doesn't work, google "php text classification".

Answer 2

A large number of libraries and example solutions exist for Python. An example of the complete sequence of solving a classification problem for text data scikit-learn.org/stable/auto_examples/model_select...
But here the question is rather not in the language or library, but in understanding what is happening and how to live with it :)
