+# PubMed Central Figures Dataset
+ 
+This dataset contains image-text pairs extracted from figures from papers in the [PubMed Central](https://www.ncbi.nlm.nih.gov/pmc/) repository. The dataset can be used to train [CLIP](https://arxiv.org/abs/2103.00020) models.
+
+The data consists of a subset of papers from PMC stored as JSON objects in a jsonlines file. Each object contains the paper id of the paper (e.g. PMC7202302) and a list of extracted figures. For each figure, the caption (encoded in unicode) and the filename of the image is given. Note that the image files themselves are not included and have to be downloaded from the [FTP server](https://www.ncbi.nlm.nih.gov/pmc/tools/ftp/) (e.g. using the scripts provided in the [accompanying code repo](https://github.com/nopperl/clip_arxiv_pmc).
