Abstract: Methods and systems for processing sets of objects and determining satisfaction levels to the sets of objects. A computing device may rank multiple sets of objects based on an object satisfaction level of a user to an individual set of objects of the multiple sets of objects. The object satisfaction level may be obtained based on operation behavioral data of the user on the individual set of objects and operation behavioral data of the user on an object of the individual set of objects. The ranked sets of objects are consistent with historic operation behavior of the user to the multiple sets of objects. The implementations herein solve data exchange problems caused by repeated search operations and further decrease an amount of data exchange between a client terminal and the computing device, therefore reducing processing loads of the computing device.
