Given a piece of text (ex. an email), I want to identify words that are not strictly necessary to the meaning of a sentence. In other word, if you remove the adjective, the sentence of the meaning remains the same.

For example, given the sentence

I am thrilled, and tremendously excited.

I would like to modify the sentence to be something like

I am excited.

Or

I am thrilled.

But, I don't want to modify a sentence like:

It identifies ill-mannered buyers

If I were just removing all adjectives, I would remove the word ill-mannered. However, in my opinion, ill-mannered is essential to the meaning of the sentence.

I know about nonrestrictive adjectie clauses, but those are required to be seperated by commas, which is not the only case I'm interested in. So I have 2 questions:

• Is there a (linguistic?) term for what I'm looking for?
• Can I identify these sorts of "unnecessary" adjectives using a rule-based system (ie. looking the parts of speech in a constituent tree)?
