Overview of our fragment-based molecular property attribution method. Molecules from different datasets are used for the fragment attribution stage (Step I), which provides each molecule's attribution fragments. The obtained fragments are then summarized for each property task (Step II and Step III), and these tasks have the corresponding attribution fragments. Next, all these fragments are clustered with their fingerprints and shown in the "Fragment Space" (Step IV). Finally, the relation map of these property tasks is measured with the distance relationship of the respective fragment fingerprints (Step V).
