An operating system involved in implementations is a software system for unified management of hardware resources and provides service interfaces to users.

    [0024] Hereinafter, implementations of the disclosure will be described in detail.

    [0025] FIG. 1 is a schematic flow chart illustrating a method for gender recognition of a user according to implementations. As illustrated in FIG. 1, the method is performed by a server and includes the following.

    [0026] At S101, the server receives user characteristic data from a mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user.

    [0027] The server receives the user characteristic data from the mobile terminal, and the user characteristic data is indicative of the usage of the mobile terminal by the user. For example, the user characteristic data may include: the number of times and the length of time the user browses men's products (such as men's wear) in shopping applications; the number of times and the length of time the user browses women's products (such as cosmetics and women's wear) in shopping applications; the length of time the user reads men's novels; the length of time the user reads women's novels; the length of time the user reads sports news; the length of time the user reads constellation news; the number of times the user takes selfies with a front camera; the number of times the user uses beauty software; the number of times and the length of time the user plays games of different types, and the like, which are not limited herein.

    [0028] At S102, the server determines, from a predetermined set of user characteristic data samples, at least one user characteristic data sample matching the user characteristic data.

    [0029] The predetermined set of user characteristic data samples is determined by the server. The server has a database for storing user characteristic data from other mobile terminals. Genders of users of these mobile terminals are known, while the gender of the user of the mobile terminal is unknown. The server can sample in the database to select multiple user characteristic data as samples to form the set of user characteristic data samples.

    [0030] The server can determine, from the predetermined set of user characteristic data samples, the at least one user characteristic data sample matching the user characteristic data.

    [0031] At S103, the server queries a preset correspondence between user characteristic data samples and reference genders and obtains at least one reference gender corresponding to the at least one user characteristic data sample.

    [0032] Since genders of users corresponding to user characteristic data in the server are known, the server can query the preset correspondence between user characteristic data samples and reference genders to obtain the at least one reference gender corresponding to the at least one user characteristic data sample.

    [0033] At S104, the server determines the gender of the user according to the at least one reference gender and sending the gender determined to the mobile terminal.

    [0034] After obtaining the at least one reference gender, the mobile terminal can further determine the gender of the user of the mobile terminal and send gender information to the mobile terminal.

    [0035] As can be seen, in implementations, the server receives the user characteristic data from the mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user. Next, the server determines the at least one user characteristic data sample matching the user characteristic data from the predetermined set of user characteristic data samples. Then, the server queries the preset correspondence between user characteristic data samples and reference genders and obtains the at least one reference gender corresponding to the at least one user characteristic data sample. Finally, the server determines the gender of the user according to the at least one reference gender, and sends the gender of the user determined to the mobile terminal. In this way, according to the user characteristic data of the mobile terminal and the predetermined set of user characteristic data samples, the server can determine the at least one reference gender, and then determine the gender of the user according to the at least one reference gender. As such, when the gender of the user of the mobile terminal is unknown, the gender of the user can be inferred accurately by collecting the user characteristic data.

    [0036] As an implementation, the user characteristic data includes multiple characteristic data of the user. The method further includes normalizing each characteristic data in the user characteristic data and the predetermined set of user characteristic data samples.

    [0037] The user characteristic data includes multiple characteristic data of the user, and a collection of the multiple characteristic data forms the user characteristic data. For example, the user characteristic data is

    where

    represents the number of times and the length of time the user browses men's products (such as men's wear) in shopping applications,

    represents the number of times and the length of time the user browses women's products (such as cosmetics and women's wear) in shopping applications,

    represents the length of time the user reads sports news, n represents the number of characteristic data in the user characteristic data.

    [0038] The server can perform normalization on the each characteristic data in the user characteristic data and the predetermined set of user characteristic data samples, so that the value of the each characteristic data is between 0 and 1. For example, in the user characteristic data, for the characteristic data

    which represents the number of times and the length of time the user browses men's products (such as men's wear) in shopping applications, the manner in which

    is normalized may include: obtaining values of all x1 in the database of the server, using the value obtained by subtracting the minimum value from the maximum value as the denominator, and using the value obtained by subtracting the minimum value from

    as the numerator, so as to normalize



    [0039] As can be seen, in implementations, the user characteristic data includes multiple characteristic data of the user. The user characteristic data and the user characteristic data samples are normalized to improve the simplicity of mathematical operations on the user characteristic data.

    [0040] As an implementation, the at least one user characteristic data sample matching the user characteristic data is determined from the predetermined set of user characteristic data samples as follows.

    [0041] Calculate a similarity value yi between the user characteristic data and the i-th user characteristic data sample in the predetermined set of user characteristic data samples according to the formula:

    represents the user characteristic data, (x1,x2,...,xn,y) represents the i-th user characteristic data sample in the user characteristic data sample set, n represents the number of characteristic data in the user characteristic data, and the smaller the similarity value yi, the higher a similarity between the user characteristic data and the user characteristic data sample. Sort similarity values yi's in ascending order, and select user characteristic data samples corresponding to the first N sorted similarity values as the at least one user characteristic data sample that matches the user characteristic data, where N is an odd number.

    [0042] The set of user characteristic data samples includes multiple user characteristic data samples. A Euclidean distance between the user characteristic data and each user characteristic data sample can be calculated as the similarity value y according to the formula. i represents any user characteristic data sample in the set of user characteristic data samples, and yi represents any similarity value among the multiple calculated similarity values.

    [0043] Sort the multiple calculated similarity values yi's in ascending order, and select user characteristic data samples corresponding to the first N sorted similarity values as the at least one user characteristic data sample that matches the user characteristic data, where N is an odd number.

    [0044] As can be seen, in implementations, the similarity values between the user characteristic data and the user characteristic data samples are calculated according to the formula:

    so that the user characteristic data samples with high similarity with the user characteristic data can be determined, which is helpful to improve reliability of gender recognition of the user.

    [0045] As an implementation, determine the gender of the user according to the at least one reference gender as follows. Determine a reference gender with a larger proportion among the at least one reference gender as the gender of the user.

    [0046] According to the at least one reference gender corresponding to the at least one user characteristic data sample, the gender of the user of the mobile terminal can be determined. For example, there are 9 reference genders, of which 6 reference genders are male and 3 reference genders are female, it indicates that the gender of the user of the mobile terminal is most likely to be male.

    [0047] As can be seen, in implementations, in the at least one reference gender, the reference gender with a larger number of occurrences is selected as the gender of the user, which is beneficial to improving accuracy of the gender recognition of the user.

    [0048] As an implementation, the method further includes the following. Update information of user characteristic data of multiple mobile terminals is obtained from a database. Multiple user characteristic data whose update time is within a preset period of time is selected to form the set of user characteristic data samples.

    [0049] User characteristic data from multiple mobile terminals are stored in the database of the server, and multiple user characteristic data samples can be obtained. Obtain the update information of the user characteristic data, and select user characteristic data whose update time is within the preset period of time as the set of user characteristic data samples. For example, the server can select, from the database, multiple user characteristic data whose update time is within one week as the set of user characteristic data samples.

    [0050] As can be seen, in implementations, the server selects multiple user characteristic data in the database whose update time is within the preset period of time as the set of user characteristic data samples, which is beneficial to improving accuracy of the gender recognition of the user.

    [0051] FIG. 2 is a schematic flow chart illustrating a method for gender recognition of a user according to implementations. As illustrated in FIG. 2, the method is performed by a mobile terminal and includes the following.

    [0052] At 201, the mobile terminal obtains user characteristic data, where the user characteristic data is indicative of usage of the mobile terminal by the user.

    [0053] At 202, the mobile terminal sends the user characteristic data to a server.

    [0054] At 203, the mobile terminal receives gender of the user determined by the server according to the user characteristic data.

    [0055] As can be seen, in implementations, the server receives the user characteristic data from the mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user. Next, the server determines the at least one user characteristic data sample matching the user characteristic data from the predetermined set of user characteristic data samples. Then, the server queries the preset correspondence between user characteristic data samples and reference genders and obtains the at least one reference gender corresponding to the at least one user characteristic data sample. Finally, the server determines the gender of the user according to the at least one reference gender, and sends the gender of the user determined to the mobile terminal. In this way, according to the user characteristic data of the mobile terminal and the predetermined set of user characteristic data samples, the server can determine the at least one reference gender, and then determine the gender of the user according to the at least one reference gender. As such, when the gender of the user of the mobile terminal is unknown, the gender of the user can be inferred accurately by collecting the user characteristic data.

    [0056] As an implementation, the user characteristic data includes multiple characteristic data, and the multiple characteristic data is associated with the gender of the user of the mobile terminal.

    [0057] Multiple characteristic data in the user characteristic data is associated with the gender of the user of the mobile terminal. For example, the characteristic data may include: the number of times and the length of time the user browses men's products (such as men's wear) in shopping applications; the number of times and the length of time the user browses women's products (such as cosmetics and women's wear) in shopping applications; the length of time the user reads men's novels; the length of time the user reads women's novels; the length of time the user reads sports news; the length of time the user reads constellation news; the number of times the user takes selfies with a front camera; the number of times the user uses beauty software; the number of times and the user browses the user plays games of different types, and the like, which are not limited herein.

    [0058] As can be seen, in implementations, the multiple characteristic data in the user characteristic data is associated with the gender of the user, and the multiple characteristic data involves some habit-related parameters of using the mobile terminal by men or women, therefore, user characteristic data can be used as a basis for determining the gender of the user.

    [0059] As an implementation, the method further includes the following before obtaining the user characteristic data. The mobile terminal obtains user identity information stored in the mobile terminal. When the gender information of the user is not included in the user identity information, the mobile terminal obtains the user characteristic data.

    [0060] Since not all users of mobile terminals will provide their own gender information when registering user accounts or binding mobile terminals, the gender of the user is unknown for the mobile terminal. When the mobile terminal detects that the gender information of the user is not included in the user identity information, the mobile terminal can obtain the user characteristic data and send the user characteristic data to the server. The server analyzes user's behavior and habits of using the mobile terminal according to the user characteristic data, and determines the gender of the user of the mobile terminal.

    [0061] As can be seen, in implementations, when the mobile terminal detects that the gender of the user is unknown, the mobile terminal collects the user characteristic data and sends the user characteristic data to the server, which is beneficial for the server to recognize the gender of the user based on the user characteristic data.

    [0062] FIG. 3 is a schematic flow chart illustrating a method for gender recognition of a user according to implementations. As illustrated in FIG. 3, the method is performed by a server and a mobile terminal, and the method includes the following.

    [0063] At S301, the mobile terminal obtains user characteristic data, where the user characteristic data is indicative of usage of the mobile terminal by the user.

    [0064] At S302, the mobile terminal sends the user characteristic data to the server.

    [0065] At S303, the server receives user characteristic data from the mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user.

    [0066] At S304, the server determines, from a predetermined set of user characteristic data samples, at least one user characteristic data sample matching the user characteristic data.

    [0067] At S305, the server queries a preset correspondence between user characteristic data samples and reference genders and obtains at least one reference gender corresponding to the at least one user characteristic data sample.

    [0068] At S306, the server determines gender of the user according to the at least one reference gender and sends the gender determined to the mobile terminal.

    [0069] At S307, the mobile terminal receives the gender of the user determined by the server according to the user characteristic data.

    [0070] As can be seen, in implementations, the server receives the user characteristic data from the mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user. Next, the server determines the at least one user characteristic data sample matching the user characteristic data from the predetermined set of user characteristic data samples. Then, the server queries the preset correspondence between user characteristic data samples and reference genders and obtains the at least one reference gender corresponding to the at least one user characteristic data sample. Finally, the server determines the gender of the user according to the at least one reference gender, and sends the gender of the user determined to the mobile terminal. In this way, according to the user characteristic data of the mobile terminal and the predetermined set of user characteristic data samples, the server can determine the at least one reference gender, and then determine the gender of the user according to the at least one reference gender. As such, when the gender of the user of the mobile terminal is unknown, the gender of the user can be inferred accurately by collecting the user characteristic data.

FIG. 4 is a schematic structural diagram illustrating a server according to implementations. As illustrated in FIG. 4, the server includes a processor, a memory, a communication interface, and one or more programs stored in the memory and configured to be executed by the processor, the one or more programs include instructions for performing the following.

    [0072] User characteristic data is received from a mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user. At least one user characteristic data sample matching the user characteristic data is determined from a predetermined set of user characteristic data samples. At least one reference gender corresponding to the at least one user characteristic data sample is obtained by querying a preset correspondence between user characteristic data samples and reference genders. Gender of the user is determined according to the at least one reference gender, and the gender determined is sent to the mobile terminal.

    [0073] As can be seen, in implementations, the server receives the user characteristic data from the mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user. Next, the server determines the at least one user characteristic data sample matching the user characteristic data from the predetermined set of user characteristic data samples. Then, the server queries the preset correspondence between user characteristic data samples and reference genders and obtains the at least one reference gender corresponding to the at least one user characteristic data sample. Finally, the server determines the gender of the user according to the at least one reference gender, and sends the gender of the user determined to the mobile terminal. In this way, according to the user characteristic data of the mobile terminal and the predetermined set of user characteristic data samples, the server can determine the at least one reference gender, and then determine the gender of the user according to the at least one reference gender. As such, when the gender of the user of the mobile terminal is unknown, the gender of the user can be inferred accurately by collecting the user characteristic data.

    [0076] A similarity value yi between the user characteristic data and the i-th user characteristic data sample in the predetermined set of user characteristic data samples is calculated according to the following formula:

    where

    represents the i-th user characteristic data sample in the user characteristic data sample set, n represents the number of characteristic data in the user characteristic data, and the smaller the similarity value yi, the higher a similarity between the user characteristic data and the user characteristic data sample.

    [0081] As can be seen, in implementations, to begin with, the server receives the user characteristic data from the mobile terminal, where the user characteristic data is indicative of usage of the mobile terminal by the user. Next, the server determines the at least one user characteristic data sample matching the user characteristic data from the predetermined set of user characteristic data samples. Then, the server queries the preset correspondence between user characteristic data samples and reference genders and obtains the at least one reference gender corresponding to the at least one user characteristic data sample. Finally, the server determines the gender of the user according to the at least one reference gender, and sends the gender of the user determined to the mobile terminal. In this way, according to the user characteristic data of the mobile terminal and the predetermined set of user characteristic data samples, the server can determine the at least one reference gender, and then determine the gender of the user according to the at least one reference gender. As such, when the gender of the user of the mobile terminal is unknown, the gender of the user can be inferred accurately by collecting the user characteristic data.
