Hand-Drawn Chemical Formulas Captured During Field Testing of the OrChemSTAR App With and Without Annotations Gained Using the Structure Matching and Recognition Engine SMARE

This dataset comprises 7909 hand-drawn chemical structure elements captured during field testing of the OrChemSTAR App in chemistry classes. It includes raw images as well as images with an overlay of recognized molecule parts based on 18 different classes relevant to chemical structure interpretation. The Annotations were done by the Structure Matching and Recognition Engine SMARE.
