Rather than trying to roll your own regex (and depending on what you're trying to do with this next) you probably want to look at CPAN and search for NLP modules (Natural Language Processing) instead. Those are likely going to do what you want WRT removing not-words as well as being able to give you more info about the words/tokens it extracts.

Oddly enough, I found almost nothing of use in CPAN related to NLP! That's very surprising. (See, for example, https://metacpan.org/pod/Text::NLP) In any event, there's more idiosyncratic processing of the words and surrounding punctuation, so it's doubtful that any CPAN module would exactly fit my needs.

The NLP modules are generally found in the "Lingua" namespace - most of the various part-of-speech taggers, lemmatizers, stemmers etc. have a Perl implementation. Some examples: Lingua::EN::Tagger Lingua::TreeTagger Lingua::FreeLing3 Lingua::EN::SENNA Lingua::CollinsParser Lingua::BrillTagger If you are going to do further NLP type analysis they are worth looking into.
