Hi, how do we extract the patterns of the negations identified? Is there any standard methods of negex we can use?

Like if I want to know which negation pattern below was identified for the negated entity.

NegEx Patterns psuedo_negations - phrases that are false triggers, ambiguous negations, or double negatives preceding_negations - negation phrases that precede an entity following_negations - negation phrases that follow an entity termination - phrases that cut a sentence in parts, for purposes of negation detection (.e.g., "but")

There's a 3rd-party plugin called negspacy based on negex.

Ah, this is better for the Discussion board, so I'm going to migrate it there.
