How to select a category automatically based on a word in WordPress post title?

I am working with an auto-posting blog where the articles come through RSS Feed. There are lots of posts publishing every day automatically. Now I need to get a category automatically based on a word in the WordPress post title.

For example: I have a category: New York and Florida.

If any post has the word New York in the title, then the category New York will select automatically during publishing.

Similarly, if any post has the word Florida in the title, then the category Florida will select automatically during publishing.

How can I do that?
