Dataset Description

Repository: https://github.com/huggingface/OBELISC
Paper: OBELISC: An Open Web-Scale Filtered Dataset of Interleaved Image-Text Documents

Dataset Summary

OBELISC is an open, massive and curated collection of interleaved image-text web documents, containing 141M documents, 115B text tokens and 353M images.

This dataset can be used to train large multimodal models, significantly improving their reasoning abilities compared to models trained solely on image/text pairs. Please refer to our paper for further details about the construction of the dataset, quantitative and qualitative analyses of OBELISC, and experiments we conducted.

Data Fields

There are 4 fields: images, texts, metadata and general_metadata.

For each example, the data in the columns images and texts are two lists of the same size, where for each index, one element and only one is not None.

For example, for the web document <image_1>text<image_2>, in images, we have [image_1,None,image_2] and in texts we have [None,text,None].

The images are replaced by their URLs, and the users have to download them themselves, for example with the library img2dataset.

In metadata, there is a string that can be transformed into a list with json.loads(example["metadata"]). This list will have the same size as the lists of images and texts, and will have a dictionary for each index where there is an image, and a None value when there is a text. This dictionary will contain the metadata of the image (original source document, unformatted source, alt-text if present, ...).

Finally, in general_metadata, there is a string that can be transformed into a dictionary, containing the URL of the document, and information about its location in the Common Crawl data.

Data Splits

There is only one split, train, that contains 141,047,697 examples.

Size

OBELISC with images replaced by their URLs weighs 666.6 GB (unwanted!) in arrow format and 377 GB in this uploaded parquet format.
