## Dataset Information

Black Swan has three variants of questions. Please find the data in the appropriate repositories:
* [BlackSwanSuite-Gen -- link](https://huggingface.co/datasets/UBC-ViL/BlackSwanSuite-Gen)
* [BlackSwanSuite-MCQ -- link](https://huggingface.co/datasets/UBC-ViL/BlackSwanSuite-MCQ)
* BlackSwanSuite-YN (this)

_This dataset contains questions for Y/N variant the Detective and Reporter tasks in Black Swan._

BlackSwanSuite contains videos of surprising events, split into three parts: the pre-event, the event, and the post-event. 
In the Y/N variant of the tasks:
* **Detective-Y/N:** Given the pre-event and the post-event videos and a hypothesis, validate if this hypothesis is possible or not.
* **Reporter-Y/N:** Given the entire video (pre-event, event, post-event) and a hypothesis, validate if this hypothesis is valid or not.


## Splits

There are two splits available in this dataset:
* **Validation:** 3334 questions, with ground truth answers
* **Test:** 3345 questions, without ground truth answers (leaderboard submissions will be open soon!)
