_DESCRIPTION = """\ The PatFig Dataset is a curated collection of over 18,000 patent images from more than 7,
|
10 |
-
000 European patent applications, spanning the year 2020. It aims to provide a comprehensive resource for research
|
11 |
-
and applications in image captioning, abstract reasoning, patent analysis, and automated documentprocessing. The
|
12 |
-
overarching goal of this dataset is to advance the research in visually situated language understanding towards more

hollistic consumption of the visual and textual data.
