+# 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.
+Addition to 1.1 is an extended set of OTSL instructions that now also offer descriptions of column / row headers and section rows.
+
+### 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.
+* html_with_text: list of HTML table structure tags together with cell content text
+* 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
+* "ched" - cell that belongs to column header
+* "rhed" - cell that belongs to row header
+* "srow" - cell that belongs to section row (header-like separator within the table)
+
+### Data Splits
+
+The dataset provides three splits
+- `train`
+- `val`
+- `test`
