US 2025/0029685 A1 · ARTIFICIAL INTELLIGENCE DEVICE AND METHOD FOR RECOGNIZING STRUCTURAL FORMULA IMAGE

Abstract

An artificial intelligence device includes a memory in which a structural formula image is stored, and a processor configured to obtain information on a plurality of atomic regions from the structural formula image, to obtain information on bonding relationships between a plurality of atoms on the basis of the information on the plurality of atomic regions, to generate an adjacency matrix on the basis of the information on the plurality of atomic regions and the information on bonding relationships between the plurality of atoms, and to generate a predetermined string format corresponding to the structural formula image on the basis of the adjacency matrix.
