Method and apparatus for checking and updating data on a client terminal

An apparatus for checking and updating data on a client terminal, comprising:

• one or more processors, and memory for storing one or more progran units executed by the one or more processors, wherein the one or more processors are configured to:
• obtain a presentation time interval between two adjacent presenting actions of target data on the client terminal, and obtaining an update time interval between two adjacent updating actions of the target data on a server;
• calculate a weighted mean value of the target data based on the presentation time interval and the update time interval, as well as a preset presentation weight and a preset update weight by:
• using a preset level division rule to determine a representation level based on the presentation time interval, and to determine an update level based on the update time interval, wherein the preset level division rule describes a first mapping between the representation level and the presentation time interval, and a second mapping between the update level and the update time interval;
• and
• calculating the weighted mean value using a following equation:
• W=(S*Ws+P*Wp)/(Ws+Wp),
• wherein W is the weighted mean value of the target data, S is the representation level corresponding to the target data, P is the update level corresponding to the target data, Ws is the preset representation weight corresponding to the target data, and Wp is the preset update weight corresponding to the target data;
• and
• determine an update check period of the client terminal for periodically performing an update operation to the target data based on the weighted mean value.

A non-transitory computer readable memory comprising a computer readable program stored thereon, wherein, when being executed, the computer readable program causes a computer to implement a method for checking and updating data on a client terminal, the method comprising:

• obtaining a presentation time interval between two adjacent presenting actions of target data on the client terminal, and obtaining an update time interval between two adjacent updating actions of the target data on a server;
• calculating a weighted mean value of the target data based on the presentation time interval and the update time interval, as well as a preset presentation weight and a preset update weight, wherein calculating the weighted mean value comprises:
• using a preset level division rule to determine a representation level based on the presentation time interval, and to determine an update level based on the update time interval, wherein the preset level division rule describes a first mapping between the representation level and the presentation time interval, and a second mapping between the update level and the update time interval;
• and
• calculating the weighted mean value using a following equation:
• W=(S*Ws+P*Wp)/(Ws+Wp),
• wherein W is the weighted mean value of the target data, S is the representation level corresponding to the target data, P is the update level corresponding to the target data, Ws is the preset representation weight corresponding to the target data, and Wp is the preset update weight corresponding to the target data;
• and
• determining an update check period of the client terminal for periodically performing an update operation to the target data based on the weighted mean value.
