# Dataset Card
## Dataset Details
This dataset contains a set of candidate documents for second-stage re-ranking on fever
(test split in [BEIR](https://huggingface.co/BeIR)). Those candidate documents are composed of hard negatives mined from
[gtr-t5-xl](https://huggingface.co/sentence-transformers/gtr-t5-xl) as Stage 1 ranker
and ground-truth documents that are known to be relevant to the query. This is a release from our paper
[Policy-Gradient Training of Language Models for Ranking](https://gao-g.github.io/), so
please cite it if using this dataset.
## Direct Use
You can load the dataset by:
```python
from datasets import load_dataset
dataset = load_dataset("NeuralPGRank/fever-hard-negatives")
```
Each example is an dictionary:
```python
>>> python dataset['test'][0]
{
"qid" : ..., # query ID
"topk" : {
doc ID: ..., # document ID as the key; None or a score as the value
doc ID: ...,
...
},
}
```
