This repository contains a private version of the XFUND dataset processed into the [**DoclingDocument**](https://ds4sd.github.io/docling/concepts/docling_document/) format using [Docling](https://github.com/DS4SD/docling).

## Dataset Overview

- **Total Samples:** 1393 annotated forms
- **Splits:**
- **train:** 1043 samples
- **validation:** 350 samples
- **Features:**
- `docling_version`: Version of the Docling document format with which the document is processed.
- `document_id`: Unique identifier for each document.
- `GroundTruthDocument`: The **DoclingDocument** object containing the annotations.
- `GroundTruthPageImages`: Images corresponding to each page.
- `GroundTruthPictures`: Pictures present in the document.
- `BinaryDocument`: Image of the form in binary format.
- `mimetype`: MIME type of the binary document.

## Source

The original XFUND dataset was introduced in the paper: [XFUND](https://aclanthology.org/2022.findings-acl.253.pdf). It consists of annotated forms in 7 languages: `DE, FR, IT, JA, ZH, PT, ES`.

## Docling Framework

The conversion to the DoclingDocument format was performed using the [Docling](https://github.com/DS4SD/docling), which provides a standardized way to represent a document.
