| | |
| | ## 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 |
| |
|
| | ### OTSL Vocabulary: |
| |
|
| | **OTSL**: new reduced table structure token format |
| | More information on the OTSL table structure format and its concepts can be read from our paper. |
| | Format of this dataset extends work presented in a paper, and introduces slight modifications: |
| |
|
| | * "fcel" - cell that has content in it |
| | * "ecel" - cell that is empty |
| | * "lcel" - left-looking cell (to handle horizontally merged cells) |
| | * "ucel" - up-looking cell (to handle vertically merged cells) |
| | * "xcel" - 2d span cells, in this dataset - covers entire area of a merged cell |
| | * "nl" - new line token |
| |
|
| | ### Data Splits |
| |
|
| | The dataset provides three splits |
| | - `train` |
| | - `val` |
| | - `test` |
