## SQUALL Dataset
To explore the utility of fine-grained, lexical-level supervision, authors introduce SQUALL, a dataset that enriches 11,276 WikiTableQuestions English-language questions with manually created SQL equivalents plus alignments between SQL and question fragments. 5-fold splits are applied to the full dataset (1 fold as dev set at each time). The subset defines which fold is selected as the validation dataset.

WARN: labels of test set are unknown.

## Source
Please refer to [github repo](https://github.com/tzshi/squall/) for source data.

```python
from datasets import load_dataset
dataset = load_dataset("siyue/squall","0")
