Description

ChemInfty Thumb.png

This dataset consists of chemical images (dataset) and their chemical meaning (see ground truth section). The 5727 chemical images were randomly collected from Japanese published patent applications in the year 2008.


  • Number of samples in the dataset: 869
  • File format: TIFF format images including binary and greyscale.
  • File Name Convention: The file names of image files and the meta data have the following name convention:
    • 2008XXXXXX_N_chem.tif: a TIFF file
    • 2008XXXXXX_N_chem.sdf: the meta data of 2008XXXXXX_NNN_chem.tif
    • The string '2008XXXXXX' expresses the patent ID and 'N' expresses the ‘N’-th elements of the multi-tiff file (See Reference \[1\]).

When you use or distribute this dataset, please inform the authors of your contact information (Name, Affiliation, E-mail address).

Disclaimer: Although the authors tried their best to provide an error-free dataset, there might be some incorrect data. If you encounter any such errors, please report them back to the authors so that the data can be updated.
