Automatically tag posts based on user-defined words [closed]

I wouldn’t call myself an expert so test what I’m offering, but you may try to add a hook when you publish the post that uses a preg_match (or similar function) to find those terms in the post content. Then, based on what you found you could add the wp_set_post_terms.
