### Dataset Summary

The WikiDT contains multi-level annotations and labels for the question-answering task based on images. Meanwhile, as the questions are answered from some table on the image, and WikiDT provides the table annotation to facilitate the diagnosis of the models and decompose the problem, WikiDT can be also directly used as a 
table recognition dataset.

The dataset contains 16,887 Wikipedia screenshot, which are segmented to 54,032 subpages since the full screenshots are potentially long. In total, there's 159,905 tables in the dataset. The number of question-answer samples is 70,652. Each QA sample contains triplets of <question, answer, full-page screenshot filename>, and is additionally annotated with retrieval labels (which subpage, and which table). 53,698 QA samples also have SQL annotation. 

For each subpage, OCR and table extraction annotations from two sources are available. While rendering the screenshots, the ground truth table annotation is recorded. Meanwhile, to make the dataset realistic, we also requested OCR and table extraction from [Amazon Textract](https://aws.amazon.com/textract/) for each subpage (results obtained during Feb.28, 2023 - Mar.6, 2023).

## Dataset Structure

Once downloaded, the WikiDT has the following parts. The downloaded files are around 77GB. Please ensure you have at least 160GB since we will be extract individual files from the tars.

```

Please concat the part files and extract them into respective folder. For example, 
run
```
cd WikiTableExtraction/
cat detection.parta* | tar x
```
to extract the `detection` folder.
Once you extracted all the tar files, the WikiDT dataset has the following file structure.

```sh
