| This dataset is converted from [SEM Shared Task 2012: Resolving the Scope and Focus of Negation](https://www.clips.ua.ac.be/sem2012-st-neg/data.html), [CD-SCO] dataset. |
|
|
| The creation of this data follows the approach of the Augment method described in [NegBERT (Khandelwal, et al. 2020)](http://www.lrec-conf.org/proceedings/lrec2020/pdf/2020.lrec-1.704.pdf). |
| That is, adding a special token ([NEG]) immediately before the predicate: |
| > This is [NEG] not a sentence. |
|
|
| Note that **the special token and the predicate is considered a whole**. That is, the actual sentence is like |
| > 'This' 'is' **'[NEG] not'** 'a' 'sentence' '.' |
