[0052] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0053] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or device comprising the element.

[0054] First, to facilitate understanding, the following part of the embodiments of the present invention first specifically explains the technical terms involved.

[0055] The terminal coverage of an application refers to the usage ratio of the application among the user group.

[0056] App usage time refers to the time users spend using the app.

[0057] Currently, the terminal coverage of an application is calculated based on statistical methods. In these statistical methods, the number of terminals covered is calculated based on one account corresponding to one terminal. However, in reality, many users have multiple accounts. In this case, the terminal coverage of an application obtained based on statistical methods is difficult to guarantee accuracy. In contrast, this application obtains relevant data for determining the terminal coverage of an application on the server side. This data, obtained on the server side, determines the changing pattern of the application's terminal coverage, and based on this changing pattern, predicts the terminal coverage.

[0058] The following first introduces the method for determining application coverage provided by an embodiment of the present invention.

[0064] S103: Obtain installation information of multiple applications installed on the terminal, where the installation information includes installation time.

[0065] S104 , determining installation coverage rates of different types of applications among multiple applications in different time periods based on the installation information, where the installation coverage rate is the installation ratio of the applications installed on the terminal.

[0066] In one embodiment, obtaining the installation coverage of the application includes obtaining the number of installations of the application, and then dividing the obtained number of installations of the application by the total number of terminals to obtain the installation coverage of the terminals.

[0067] S105 , determining usage durations of different types of applications among the multiple applications based on the installation information.

[0068] In one embodiment, the usage duration includes an average usage duration, and the average usage duration includes obtaining the sum of the usage durations of each terminal, and then dividing the sum of the usage durations by the number of installations of the application.

[0069] S106, determining the change pattern information of the installation coverage and usage time of the same type of applications based on the similarity, installation coverage and usage time, wherein the change pattern information includes the corresponding relationship between the usage time and the installation coverage.

[0070] In one embodiment, the variation rule includes a variation curve and a variation function.

[0071] S107: Determine the application coverage of the same type of applications in the target time period according to the change rule information.

[0095] In this step, the linear regression algorithm is used for fitting, and the linear regression formula is:

[0096]

[0097] The historical time periods and the installation coverage rates corresponding to the historical time periods are input into the above formula to obtain a first fitting curve of the installation coverage rate.

[0098] S212: Fit the usage duration of applications of the same type in multiple historical time periods to obtain a second fitting curve.

[0099] In this step, a linear regression algorithm is used for fitting, and the linear regression formula is the above formula. The historical time period and the average usage time corresponding to the historical time period are input into the above formula for fitting to obtain a second fitting curve of the average usage time.

[0100] S213 , fitting the first fitting curve and the second fitting curve to obtain information on changes in installation coverage and usage duration of applications of the same type at different times.

[0101] In this step, a linear regression algorithm is used for fitting. The linear regression formula is the above formula. The average usage time corresponding to the same historical time period and the installation coverage of the application are input into the above formula for fitting to obtain the final fitting curve corresponding to the average usage time and installation coverage.

[0102] S214: Obtain terminal coverage information of the same type of applications in the target time period according to the terminal coverage prediction curve.

[0103] In this step, the terminal coverage of the application can be obtained by inputting the average usage time into the final fitting curve through the final fitting curve.

[0104] In this step, the target time period includes the present time period, the historical time period, and the future time period.
