GenDocVQA

This dataset provides a broad set of documents with questions related to their contents. These questions are non-extractive, meaning that the model, which solves our task should be generative and compute the answers by itself.

Dataset Details

Uses

Direct Use

In order to load dataset using following code:

ds = datasets.load_dataset('lenagibee/GenDocVQA')

ds is a dict consisting from two splits train and validation.

To open the image use following example:

from PIL import Image
im = Image.open(ds['train'][0]['image_path'])

Dataset Structure

All the necessary data is stored in the following archives:

Data parsing is already implemented in the attached dataset generator. Images should be processed by the user himself.

The train split contains 260814 questions and dev (validation) contains 28473.

Features of dataset

The features of the dataset are the following:

features = datasets.Features(
            {
                "unique_id": datasets.Value("int64"),
                "image_path": datasets.Value("string"),
                "ocr": datasets.Sequence(
                    feature={
                        'text': datasets.Value("string"), 
                        'bbox': datasets.Sequence(datasets.Value("int64")),
                        'block_id': datasets.Value("int64"),
                        'text_id': datasets.Value("int64"),
                        'par_id': datasets.Value("int64"),
                        'line_id': datasets.Value("int64"),
                        'word_id': datasets.Value("int64")
                    }
                ),
                "question": datasets.Value("string"),
                "answer": datasets.Sequence(datasets.Value("string")),
                
            }

Features description

unique_id - integer, an id of a question
image_path - string, path to the image for a question (includes downloaded path)
ocr - dictionary, containing lists, where each element is an information related to a single word
- text - string, a word itself
- bbox - list of 4 integers, a bounding box of the word
- block_id - integer, an index of the block, where the word is located
- text_id - integer, an index of the set of paragraphs, where the word is located
- par_id - integer, an index of the paragraph, where the word is located
- line_id - integer, an index of the line, where the word is located
- word_id - integer, an index of the word
question - string, containing the question
answer - list of strings, containing the answers to the question, can be empty (non-answerable)

Images

Are divided inside the archive into dev and train folders. Just regular images in PNG, JPG formats. You can use any image library to process them.

OCR

Same as the Images are divided into dev and train folders. Represented as JSON files.

OCR JSON Description

It is a list of elements, where each represents an information about the single word extracted by the ABBYY FineReader OCR, and contains fields in following order:

block_id - integer, an index of the block, where the word is located
text_id - integer, an index of the set of paragraphs, where the word is located
par_id - integer, an index of the paragraph, where the word is located
line_id - integer, an index of the line, where the word is located
word_id - integer, an index of the word
bbox - list of 4 integers, a bounding box of the word
text - string, a word itself

Annotations

dev (validation) and train splits are located in the archive. Question lists are represtened by csv files with following columns:

unique_id - an id of the question
split
question
answer
image_filename - a filename of the related image
ocr_filename - a filename of the json file, containing the related OCR data

Data Processing

The questions from each dataset were filtered by the types of the questions, leaving only non-extractive questions, related to one page. After that the questions were paraphrased.
