# Dataset Card for FinTabNet_OTSL

## Dataset Description

- **Homepage:** https://ds4sd.github.io
- **Paper:** https://arxiv.org/pdf/2305.03393

### Dataset Summary

This dataset is a conversion of the original [FinTabNet](https://developer.ibm.com/exchanges/data/all/fintabnet/) into the OTSL format presented in our paper "Optimized Table Tokenization for Table Structure Recognition". The dataset includes the original annotations amongst new additions.

### Dataset Structure

* cells: origunal dataset cell groundtruth (content).
* otsl: new reduced table structure token format
* html: original dataset groundtruth HTML (structure).
* html_restored: generated HTML from OTSL.
* cols: grid column length.
* rows: grid row length.
* image: PIL image


### Data Splits

The dataset provides three splits
- `train`
- `val`
- `test`
