Dataset Card for DocVQA Dataset

Dataset Description

Point of Contact from curators: Minesh Mathew, Dimosthenis Karatzas, C. V. Jawahar
Point of Contact Hugging Face: Pablo Montalvo

Dataset Summary

DocVQA dataset is a document dataset introduced in Mathew et al. (2021) consisting of 50,000 questions defined on 12,000+ document images.

Usage

This dataset can be used with current releases of Hugging Face datasets library. Here is an example using a custom collator to bundle batches in a trainable way on the train split


from datasets import load_dataset

docvqa_dataset = load_dataset("pixparse/docvqa-single-page-questions", split="train"
)
next(iter(dataset["train"])).keys()
>>> dict_keys(['image', 'question_id', 'question', 'answers', 'data_split', 'ocr_results', 'other_metadata'])

image will be a byte string containing the image contents. answers is a list of possible answers, aligned with the expected inputs to the ANLS metric.

The loader can then be iterated on normally and yields questions. Many questions rely on the same image, so there is some amount of data duplication.

Data Splits

Train

10194 images, 39463 questions and answers.

Validation

1286 images, 5349 questions and answers.

Test

1,287 images, 5,188 questions.
