It is based on US Patent Office Complex Work Units and can be used, e.g., for testing of software such as OSRA, ChemReader, CLiDE, and ChemOCR. It comprises 5735 images and ground-truth MOL files, which makes it the largest such validation set available to the public to the best of our knowledge. It is available for download at: http://cactus.nci.nih.gov/osra http://osra.sourceforge.net/ We would like to thank Dr. Steve Boyer and Dr. John Kinney for collaboration in developing the validation set. Sincerely, Igor Filippov and Marc Nicklaus
