The dataset consists of CC-BY-4.0 licensed open access papers and the annotations on-top are provided under the same license. Train, test and validation splits are provided as separate folders containing the image files and a single json file containing the annotations in COCO format.

The classes are close to the TFT-ID dataset and extend into 3 chemistry specific labels. chem_reaction contains everything with reaction arrows, chem_structures are structural formulas without reactions and chem_table is used for tables containing structural formula.

The dataset is also available on Roboflow, allowing to directly convert the annotatios into different formats.
