# 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:

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

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

To open the image use following example:
```python
from PIL import Image
im = Image.open(ds['train'][0]['image_path'])
```

Dataset generator:
https://huggingface.co/datasets/lenagibee/GenDocVQA/resolve/main/GenDocVQA.py?download=true

## Dataset Structure

All the necessary data is stored in the following archives:

* Images: https://huggingface.co/datasets/lenagibee/GenDocVQA/resolve/main/archives/gendocvqa2024_imgs.tar.gz?download=true
* OCR: https://huggingface.co/datasets/lenagibee/GenDocVQA/resolve/main/archives/gendocvqa2024_ocr.tar.gz?download=true
* Annotations: https://huggingface.co/datasets/lenagibee/GenDocVQA/resolve/main/archives/gendocvqa2024_annotations.tar.gz?download=true

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:
```python
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:

1. `block_id` - integer, an index of the block, where the word is located
2. `text_id` - integer, an index of the set of paragraphs, where the word is located
3. `par_id` - integer, an index of the paragraph, where the word is located
4. `line_id` - integer, an index of the line, where the word is located
5. `word_id` - integer, an index of the word
6. `bbox` - list of 4 integers, a bounding box of the word
7. `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:

1. `unique_id` - an id of the question
2. `split`
3. `question`
4. `answer`
5. `image_filename` - a filename of the related image
6. `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.
