Negation detector. A roberta-large used for detecting negation words in sentences. A negation word will get label "Y".
Because the negation style in training dataset(2250 items) is not enough, maybe some kinds of negated sentences will get all "N" label.
Using negation annotation and sentence from CondaQA and cd-sco. You can get the CondaQA dataset through both github and huggingface. As for github:
