    fragSMILES as a chemical string notation for advanced fragment and chirality representation by Fabrizio Mastrolorito, Fulvio Ciriaco, Maria Vittoria Togo, Nicola Gambacorta, Daniela Trisciuzzi, Cosimo Damiano Altomare, Nicola Amoroso, Francesca Grisoni, Orazio Nicolotti

    Published 2025-01-01
    “…In this paper, we present fragSMILES, a novel fragment-based molecular representation in the form of string. fragSMILES encode fragments in a ‘chemically-meaningful’ way via a novel graph-reduction approach, allowing to obtain an efficient, interpretable, and expressive molecular representation, which also avoids fragment redundancy. fragSMILES contributes to the field of fragment-based representation, by reporting fragments and their ‘breaking’ bonds independently. …”
