Introduction

The purpose of this competition is to attract the attention of researchers in the field of Optical Character Recognition (OCR) to the challenge of recognizing handwritten chemical structures. This challenge is distinct from the traditional recognition of handwritten text and mathematical formulas, as the data format of chemical structures is more complex. Solving this problem would not only be an academic breakthrough but also have practical applications, particularly in the education of middle and high school organic chemistry. We have established a new benchmark for this issue and released a self-built dataset for handwritten chemical structure recognition, named EDU-CHEMC. We collected 60,974 images containing chemical structures from real educational settings in middle and high schools. The provided annotations include original Chemfig strings and structured strings after regularization, facilitating researchers in establishing baselines. The sole task of this competition is to accurately extract the information of the structural formulas in the images, including atoms, chemical bonds, and their connections. We hope that by hosting this competition, we can promote the development of the subfield of handwritten chemical image structure recognition.
