Such sys- loo - tem may comprise processors accessible to platform data that comprises a plu- _ rality of users and a plurality of associated data fields, and a memory storing = instructions that, when executed by the processors, cause the system to perform = a method. The method may comprise obtaining a first subset users and associ- ated first tags; determining, respectively for the associated data fields, at least — = Data Store 108 Data Store 109 a difference between the first subset users and at least some of the plurality of users; responsive to determining the difference exceeding a first threshold, de- = = termining the data field as a key data field; determining data of the correspond- ing key data fields associated with the first subset users as positive samples; obtaining, based on the key data fields, a second subset users and associated System 102 data as negative samples; and training a rule model with the positive and neg- ative samples. = Processor Memory 104 106 — Computing 11 Device 120 GC : 11 t:t 11 Computing Device 110 • • • Computing Device 111 • • • Computing Device 112 t:t 11 \..
