Scientific Figures and Captions Dataset from research papers

This repository contains the Scientific Figures and Captions dataset, which includes approximately 4.2 million entries of scientific figures and their corresponding captions extracted from academic papers on arXiv. This dataset is intended for research purposes in the fields of computer vision and natural language processing, particularly for tasks related to image captioning and automated figure analysis.

Dataset Description

The dataset is structured as a Parquet dataframe with two columns:

image_filename: This column contains the relative paths to image files.
caption: This column contains the textual captions associated with each image.

Images are stored under dataset/figures/ and are compressed into multiple parts (.z01, .z02, ..., .z103) with a final .zip file that encompasses all parts. This format is used for efficiently handling large datasets.

Extraction Instructions

To access the images, you must first decompress the multi-part ZIP archive. Make sure you have all parts of the archive (.z01 to .z103 and the .zip file) in the same directory. Most decompression tools will recognize and handle multi-part ZIP files seamlessly.

Here is an example using the command line with unzip:

# Navigate to the directory containing the compressed parts
cd dataset/figures

# Use unzip to extract the first set of images
unzip compressedfigures.zip

# combine the second set of images
cat compressedfigures_part2* > compressedfigures_part2.tar.gz
# unzip second set of images
tar xf compressedfigures_part2.tar.gz

# You're good to go!

This will extract the contents into the dataset/figures/ directory. Ensure that you have enough storage space to accommodate the uncompressed images.

Usage Example

To use the dataset in your Python projects, you'll need to read the Parquet file into a DataFrame. Here is an example using pandas:

import pandas as pd

# Load the dataset into a DataFrame
df = pd.read_parquet('dataset.parquet')

# Display the first few entries
df.head()

Once the dataset is loaded, you can use it as follows:

from PIL import Image
import matplotlib.pyplot as plt

# Example function to display an image with its caption
def show_image_with_caption(image_path, caption):
    img = Image.open(image_path)
    plt.imshow(img)
    plt.title(caption)
    plt.axis('off')  # Hide the axis
    plt.show()

# Display the first image and its caption
first_image_path = df.loc[0, 'image_filename']
first_caption = df.loc[0, 'caption']
show_image_with_caption(first_image_path, first_caption)
