The labels of OCNLI is mistakenly reversed
The two labels in OCNLI, neutral and entailment, are mistakenly reversed in BUFFET.
As can be seen in the screenshot, the label of the first sentence is neutral.
However, the label of the same piece of the data in the original dataset is entailment.
Original dataset: https://github.com/CLUEbenchmark/OCNLI/blob/main/data/ocnli/train.30k.json
The labels of all other items are reversed as well.
Thank you for reporting this issue! Sorry, somehow I didn't receive this notification and just realized we had this issue. I'll work on it today to investigate and fix this issue!
I quickly checked the preprocessing code and found the mapping functions of neutral and entailment was flipped, when we convert the original OCNLI data into the BUFFET format.

I will fix this issue and re-upload the data!
