FUNSD is one of the limited publicly available datasets for information extraction from document images.
The information in the FUNSD dataset is defined by text areas of four categories ("key", "value", "header", "other", and "background")
and connectivity between areas as key-value relations. Inspecting FUNSD, we found several inconsistency in labeling, which impeded its
applicability to the key-value extraction problem. In this report, we described some labeling issues in FUNSD and the revision we made
to the dataset.

## Dataset Description

- **Paper:** [https://arxiv.org/abs/2010.05322](https://arxiv.org/abs/2010.05322)

### Dataset Summary

This is the revised version of the [FUNSD dataset](https://huggingface.co/datasets/nielsr/funsd) as proposed by [Vu, H. M., & Nguyen, D. T. N. (2020)](https://arxiv.org/abs/2010.05322).

### Supported Tasks and Leaderboards

The Form Understanding challenge comprises three tasks, namely word grouping, semantic-entity labeling, and entity linking.

## Dataset Structure

### Data Instances

[More Information Needed](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)

### Data Fields

The data fields are the same among all splits.

- `id`: a `string` feature - GUID.
- `words`: a `list` of `string` features.
- `bboxes`: a `list` of `list` with four (`int`) features.
- `ner_tags`: a `list` of classification labels (`int`). Full tagset with indices:

```python
{'O': 0, 'B-HEADER': 1, 'I-HEADER': 2, 'B-QUESTION': 3, 'I-QUESTION': 4, 'B-ANSWER': 5, 'I-ANSWER': 6}
```

- `image_path`: a `string` feature.
