EconBiz Images for Text Extraction from Scholarly Figures

Böschen, Falk; Scherp, Ansgar

Scholarly figures are data visualizations like bar charts, pie charts, line graphs, maps, scatter plots or similar figures. Text extraction from scholarly figures is useful in many application scenarios, since text in scholarly figures often contains information that is not present in the surrounding text. This dataset is a corpus of 121 scholarly figures from the economics domain evaluating text extraction tools. We randomly extracted these figures from a corpus of 288,000 open access publications from EconBiz. The dataset resembles a wide variety of scholarly figures from bar charts to maps. We manually labeled the figures to create the gold standard.

We adjusted the provided gold standard to have a uniform format for all datasets. Each figure is accompanied by a TSV file (tab-separated values) where each entry corresponds to a text line which has the following structure:

  • X-coordinate of the center of the bounding box in pixel
  • Y-coordinate of the center of the bounding box in pixel
  • Width of the bounding box in pixel
  • Height of the bounding box in pixel
  • Rotation angle around its center in degree
  • Text inside the bounding box

In addition we provide the ground truth in JSON format. A schema file is included in each dataset as well. The dataset is accompanied with a ReadMe file with further information about the figures and their origin.
