DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. The described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

FIG. 1 is a flowchart of an embodiment of an application program recommending method according to the present disclosure. As shown in FIG. 1, this embodiment may be executed by a terminal, or may be executed by a server that communicates with the terminal, which is not limited. The method in this embodiment may include:

Step S101. Acquire current context information of the terminal.

Step S102. Acquire an amount of context information generated when the terminal runs a first application program, where the first application program refers to an application program stored in the terminal.

Step S103. Determine a to-be-used recommending mechanism according to the amount of the context information generated when the terminal runs the first application program, and determine, according to the to-be-used recommending mechanism, a second application program corresponding to the current context information, where the second application program refers to a to-be-recommended application program.

Step S104. Display the second application program.

In this embodiment, the current context information of the terminal is acquired. For example, the current context information may include information acquired by a sensor. The information acquired by the sensor is referred to as sensor information and use information of an application program. The sensor information includes but is not limited to the following information: Global Positioning System (GPS) sensor information, acceleration sensor information, orientation sensor information, time sensor information, and the like. Therefore, the current context information may indicate information about a geographical location in which the terminal currently locates, time information, and whether the terminal is in a moving state or a static state. The current context information may further indicate whether the terminal is in a fast moving state (for example, riding on a vehicle) or in a slow moving state (for example, walking). If a current user is using an application program in the terminal, the current context information may include use information of the application program, for example, an identifier of the application program that is being used, start time of using the application program, current duration of using the application program, and the like. The current context information may further include but is not limited to the following information: call information, short message service (SMS) message information, network connection information, and the like.

The current context information of the terminal may be acquired when the terminal is powered on, the current context information of the terminal may be acquired when the user unlocks the terminal, the current context information of the terminal may also be acquired at each preset time node, and the current context information of the terminal may also be acquired according to a preset gesture of a user operation, which is not limited in this embodiment of the present disclosure.

The amount of the context information generated when the terminal runs the first application program may be further acquired, where the context information may be sensor information and use information of the first application program when the terminal runs the first application program. When the terminal runs “Sina Weibo”, running time and running duration of “Sina Weibo”, a geographical location in which the terminal locates, acceleration information of the terminal, whether the terminal is in a call, whether the terminal sends an SMS message, and the like may be acquired. If the terminal runs an application program, for example, “Sina Weibo”, for the first time in the morning of January 1, context information generated when the terminal runs “Sina Weibo” at this moment may be acquired, and in this case, the amount of the context information generated when the terminal runs an application program is 1. If the terminal runs “Moji Weather” in the afternoon of January 1, context information generated when the terminal runs “Moji Weather” at this moment may be acquired, and in this case, the amount of the context information generated when the terminal runs an application program is 2. If the terminal runs “Sina Weibo” in the morning of January 2, context information generated when the terminal runs “Sina Weibo” at this moment may be acquired, and in this case, the amount of context information generated when the terminal runs an application program is 3. If the terminal runs “Moji Weather” in the afternoon of January 2, context information generated when the terminal runs “Moji Weather” at this moment may be acquired, and in this case, the amount of the context information generated when the terminal runs an application program is 4, and so on. Therefore, the amount of the context information generated when the terminal runs the first application program may be acquired.

After the amount of the context information generated when the terminal runs the first application program is acquired, the to-be-used recommending mechanism of an application program is determined according to the amount, and then the second application program corresponding to the current context information is determined according to the to-be-used recommending mechanism. For example, when the amount of the context information generated when the terminal runs the first application program is relatively small, it may be determined that the to-be-used recommending mechanism of an application program may be an application program use rule preset by the user. If the current context information indicates that current time is 7:30, and the preset application program use rule may indicate that application programs to be recommended to the user during 7:00 and 8:00 are “Headlines Today”, “Sina Weibo”, and “Moji Weather”, it may be determined that the second application program includes: “Headlines Today”, “Sina Weibo”, and “Moji Weather”.

Optionally, the recommending mechanism includes at least one of a use rule and a use model.

The determining a to-be-used recommending mechanism according to the amount of the context information generated when the terminal runs the first application program, and determining, according to the to-be-used recommending mechanism, a second application program corresponding to the current context information includes, if the amount of the context information generated when the terminal runs the first application program is less than or equal to a first preset value, determining, according to the use rule, a to-be-recommended application program corresponding to the current context information; if the amount of the context information generated when the terminal runs the first application program is greater than or equal to a second preset value, determining, according to the use model, a to-be-recommended application program corresponding to the current context information; and if the amount of the context information generated when the terminal runs the first application program is greater than the first preset value and less than the second preset value, determining, according to the use rule and the use model, a to-be-recommended application program corresponding to the current context information. Further, the application program corresponding to the current context information is determined according to the use rule; the application program corresponding to the current context information is determine according to the use model; the application program determined according to the use rule and the application program determined according to the use model are both used as to-be-recommended application programs corresponding to the current context information; or a same application program in application program determined according to the use rule and the application program determined according to the use model is used as the to-be-recommended application program corresponding to the current context information.

It should be noted that, the first preset value and the second preset value may be determined according to an actual application scenario, which is not limited herein.

For example, if the amount of the context information generated when the terminal runs the first application program is less than or equal to the first preset value, and if the user just starts to use an application program in the terminal, the to-be-recommended application program corresponding to the current context information may be determined according to the use rule. If the use rule indicates that the user preferably uses “Headlines Today”, “Sina Weibo”, and “Moji Weather” in a case of the current context information, it is determined that “Headlines Today”, “Sina Weibo”, and “Moji Weather” are currently to be recommended. Therefore, when historical information of using an application program by the user is insufficient to establish a use model, a to-be-recommended application program can also be determined.

For example, if the amount of the context information generated when the terminal runs the first application program is greater than the first preset value and less than the second preset value, and if the user has used the application program in the terminal for a period of time, the to-be-recommended application program corresponding to the current context information may be determined according to the use rule and the use model. If the use rule indicates that the user preferably uses “Headlines Today”, “Sina Weibo”, and “Moji Weather” in a case of the current context information, and if the use model indicates that the user preferably uses “Sina Weibo”, “Moji Weather”, and “Headlines Today” in a case of the current context information, it is determined that “Sina Weibo” and “Moji Weather” are currently recommended; or, it is determined that “Sina Weibo”, “Moji Weather”, “Headlines Today”, and “Gmail” (a free Internet mail service provided by Google) are currently recommended. Therefore, determining the to-be-recommended application program according to the use rule and the use model can improve accuracy of predicting an application program.

For example, if the amount of the context information generated when the terminal runs the first application program is greater than or equal to the second preset value, and if the user has used an application program in the terminal for a long time, the to-be-recommended application program corresponding to the current context information may be determined according to the use model. If the use model indicates that the user preferably uses “Sina Weibo”, “Moji Weather”, and “Headlines Today” in a case of the current context information, it is determined that “Sina Weibo”, “Moji Weather”, and “Headlines Today” are currently to be recommended.

After the foregoing to-be-recommended second application program is determined, the foregoing to-be-recommended second application program may be displayed. For example, an identifier (for example, an icon) of the to-be-recommended application program is displayed on a display screen of the terminal; the foregoing to-be-recommended application program may be displayed in a list manner, or the foregoing to-be-recommended application program may be displayed in an icon (a format of an icon) tiling manner. Therefore, the user may select, from the foregoing displayed to-be-recommended application program, an interesting application program for operations.

In the application program recommending method provided in the embodiment of FIG. 1, current context information of a terminal is acquired, and an amount of context information generated when the terminal runs a first application program is acquired, where the first application program refers to an application program stored in the terminal; then a to-be-used recommending mechanism is determined according to the amount of the context information generated when the terminal runs the first application program, and a second application program corresponding to the current context information is determined according to the to-be-used recommending mechanism, where the second application program refers to a to-be-recommended application program; and the second application program is displayed. In this way, accuracy of predicting an application program to be used by a user is improved. Moreover, when historical information of using an application program by the user is insufficient, a to-be-recommended application program can also be accurately determined, which improves user experience.

FIG. 2 is a flowchart of an embodiment of an application program recommending method according to the present disclosure. As shown in FIG. 2, this embodiment may be executed by a terminal, or may be executed by a server that communicates with the terminal, which is not limited. The method in this embodiment may include:

Step S201. Acquire context information generated when the terminal runs a first application program, where the first application program refers to an application program stored in the terminal.

In this embodiment, the context information generated when the terminal runs the first application program may be acquired, for example, use information and sensor information, of an application program, generated when the terminal runs the application program may be acquired. If the terminal runs “Sina Weibo”, time, duration, a geographical location, acceleration information, whether the terminal is in a call, whether the terminal sends an SMS message, and the like generated when the terminal runs “Sina Weibo” may be acquired.

Acceleration information is used as an example for description: Acceleration information at a moment is acquired, and each piece of acceleration information may be represented as a four-tuples <time, x-axis acceleration, y-axis acceleration, z-axis acceleration>. It should be noted that, there may be multiple representation forms of the acceleration information, which include but are not limited to the foregoing example, and the foregoing example merely lists a tuple-based representation manner.

After the context information generated when the terminal runs the first application program is acquired, a use rule and a use model may be generated according to the context information generated when the terminal runs the first application program, which may include S202 and S203.

Step S202. Extract a context information characteristic value of the first application program according to the context information generated when the terminal runs the first application program.

In this embodiment, the context information characteristic value, of the first application program, generated when the terminal runs the first application program may be extracted according to the context information generated when the terminal runs the first application program. The context information characteristic value of the first application program may include an identifier (for example, name) of the first application program and a characteristic value. The context information characteristic value of the first application program is as follow:

application 1 characteristic 1: value 1 characteristic 2: value 2 . . . characteristic n: value n

application 2 characteristic 1: value 1 characteristic 2: value 2 . . . characteristic n: value n

application m characteristic 1: value 1 characteristic 2: value 2 . . . characteristic n: value n

For example, characteristic: value may be: time: 7:00 to 8:00, or day of a week: Wednesday, or acceleration: a value, or whether the terminal is in a call: yes or no, or whether the terminal sends an SMS message: yes or no.

The following uses acceleration information in the acquired context information generated when the terminal runs the first application program as an example to describe how to extract a characteristic value. The acceleration information may be analyzed. Characteristic values such as an acceleration average value, variance, and a Fourier transform sum during a period of time of running the application program by the user are extracted as follows:

<x-axis acceleration average value, x-axis acceleration variance, x-axis acceleration maximum value, x-axis acceleration minimum value, x-axis acceleration Fourier transform sum, y-axis acceleration average value, y-axis acceleration variance, y-axis acceleration maximum value, y-axis acceleration minimum value, y-axis acceleration Fourier transform sum, z-axis acceleration average value, z-axis acceleration variance, z-axis acceleration maximum value, z-axis acceleration minimum value, and z-axis acceleration Fourier transform sum>.

Step S203. Generate a use rule and a use model according to the context information characteristic value of the first application program.

In this embodiment, the use model may be generated according to the context information characteristic value of the first application program using a machine training and learning method, and further, a generated use model may be stored. For example, a use model library may be established, and a use model generated each time may be stored in the use model library. The machine training method may include a Bayes model, a linear regression model, a decision tree model, an artificial neural network model, or the like, which is not limited in this embodiment of the present disclosure. In this embodiment, that the machine training method is the Bayes model is used as an example for description:

(1) Calculating a prior probability of each application, for example:

application 1 probability value 1

application 2 probability value 2 . . .

application m probability m

(2) Calculating a conditional probability corresponding to each characteristic value, for example:

characteristic value 1 probability value 1

characteristic value 2 probability value 2

characteristic value 3 probability value 3 . . .

characteristic value n probability value n

In this embodiment, the use rule may be generated according to the context information characteristic value of the application program by selecting a rule generating method, and further, a generated use rule may be stored. For example, a use rule library may be established, and a use rule generated each time may be stored in the use rule library. In a feasible implementation manner, a priority recommended for a second application program under a preset condition is determined according to the context information characteristic value of the first application program; the priority recommended for the second application program under the preset condition is used as the use rule; that the preset condition is a time statistical rule is used as an example in the following to describe a use rule generating process:

Assuming that a use probability of “Sina Weibo” between 7:00 and 8:00 by the user is 68 percent (%), a use probability of “Moji Weather” between 7:00 and 8:00 by the user is 15%, and a use probability of “Gmail” between 7:00 and 8:00 by the user is 5%, then a recommending priority of the application programs is that “Sina Weibo”>“Moji Weather”>“Gmail”. Therefore, the generated use rule is that the first three application programs recommended to be used between 7:00 and 8:00 are “Sina Weibo”, “Moji Weather”, and “Gmail”.

Step S204. Acquire current context information of the terminal.

In this embodiment, a specific implementation process of S204 is similar to a implementation process of S101 in the method embodiment of FIG. 1 of the present disclosure. For details, reference may be made to relevant records in the foregoing method embodiment of the present disclosure, and details are not described herein again. After acquiring the current context information of the terminal, the terminal may determine the second application program corresponding to the current context information.

How the terminal determines the second application program corresponding to the current context information may be implemented using S205 and S206.

Step S205. Acquire an amount of the context information generated when the terminal runs the first application program.

In this embodiment, the amount of the context information that is generated when the terminal runs the first application program and that is acquired in S201 may be acquired. A specific implementation process is similar to a specific implementation process of S102 in the method embodiment of FIG. 1 of the present disclosure. For details, reference may be made to relevant records in the foregoing method embodiment of the present disclosure, and details are not described herein again.

Step S206. Determine a to-be-used recommending mechanism according to the amount of the context information generated when the terminal runs the first application program, and determine, according to the to-be-used recommending mechanism, a second application program corresponding to the current context information, where the second application program refers to a to-be-recommended application program.

In this embodiment, the amount of the context information that is generated when the terminal runs the first application program and that is acquired in S201 may be acquired. A specific implementation process is similar to a implementation process of S103 in the method embodiment of FIG. 1 of the present disclosure. For details, reference may be made to relevant records in the foregoing method embodiment of the present disclosure, and details are not described herein again.

In an alternative implementation manner, the specific implementation process of S206 may be as follows: After the current context information of the terminal is acquired, the context information characteristic value is extracted according to the current context information; the to-be-used recommending mechanism is determined according to the amount of the context information generated when the terminal runs the first application program, and the second application program corresponding to the context information characteristic value is determined according to the to-be-used recommending mechanism, where the second application program refers to a to-be-recommended application program.

The current context information characteristic value is extracted according to the current context information, where the current context information characteristic value may be, for example, time: 7:00 to 8:00, day of a week: Wednesday, whether the terminal is in a call: yes, or whether the terminal sends an SMS message: no.

In this embodiment, if the amount that is of the context information generated when the terminal runs the first application program and that is acquired in S205 is less than or equal to a first preset value, it is determined that the recommending mechanism is the use rule, and then the to-be-recommended second application program corresponding to the current context information characteristic value is determined according to the use rule. For example, if context information generated when the user uses an application program is acquired 10 times, it is not suitable to use the use model to determine the to-be-recommended second application program corresponding to the current context information characteristic value.

If the amount that is of the context information generated when the terminal runs the first application program and that is acquired in S205 is greater than or equal to a second preset value, it is determine that the recommending mechanism is the use rule, and then the to-be-recommended second application program corresponding to the current context information characteristic value is determined according to the use model. For example, context information generated when the user uses an application program is acquired 100 times, and then at least one to-be-recommended application program corresponding to the current context information characteristic value is determined using the use model.

If the amount that is of the context information generated when the terminal runs the first application program and that is acquired in S205 is greater than the first preset value and less than the second preset value, the to-be-recommended application program corresponding to the current context information characteristic value is determined according to the use rule and the use model. For example, context information generated when the user uses an application program is acquired 50 times, and then the to-be-recommended second application program corresponding to the current context information characteristic value may be determined using the use model and the use rule. The application program corresponding to the current context information characteristic value is determined according to the use rule; the application program corresponding to the current context information characteristic value is determined according to the use model; the application program determined according to the use rule and the application program determined according to the use model are both used as to-be-recommended application programs corresponding to the current context information characteristic value; or a same application program in the application program determined according to the use rule and the application program determined according to the use model is used as the to-be-recommended application program corresponding to the current context information characteristic value. For example, the application programs that correspond to the current context information characteristic value and are determined according to the use rule are “Sina Weibo”, “Moji Weather”, and “Gmail”, the application programs that correspond to the current context information characteristic value and are determined according to the use rule are “Headlines Today”, “Sina Weibo”, and “Moji Weather”. Then finally determined to-be-recommended application programs are “Sina Weibo” and “Moji Weather”; or the finally determined to-be-recommended application programs are “Sina Weibo”, “Moji Weather”, “Gmail”, and “Headlines Today”.

S207. Display the second application program.

In this embodiment, a specific implementation process of S207 is similar to a specific implementation process of S104 in the method embodiment of FIG. 1 of the present disclosure. For details, reference may be made to relevant records in the foregoing method embodiment of the present disclosure, and details are not described herein again.

In this embodiment, context information generated when a terminal runs a first application program is acquired, where the first application program refers to an application program stored in the terminal; a context information characteristic value of the first application program is extracted according to the context information generated when the terminal runs the first application program; then a use rule and a use model are generated according to the context information characteristic value of the first application program; then a to-be-used recommending mechanism is determined according to an amount of the context information generated when the terminal runs the first application program; and a second application program corresponding to current context information is determined according to the to-be-used recommending mechanism, where the second application program refers to a to-be-recommended application program. In this way, accuracy of predicting an application program to be used by a user is improved. Moreover, when historical information of using an application program by the user is insufficient to establish a use model, a to-be-recommended application program can be determined according to a use rule, which improves user experience.

FIG. 3 is a flowchart of an embodiment of an application program recommending method according to the present disclosure. As shown in FIG. 3, on a basis of the method embodiment shown in FIG. 2, further, the method in this embodiment may further include:

Step S301. Acquire feedback information of the second application program.

In this embodiment, after the foregoing second application program is displayed, the feedback information of the second application program may be further acquired. In a feasible implementation manner, the feedback information of the second application program may include use time and use duration of the second application program, for example, recommended application programs are “Sina Weibo”, “Moji Weather”, and “Gmail”. If the user uses “Sina Weibo” according to the recommended application programs, but does not use “Moji Weather” and “Gmail”, the feedback information of the recommended application programs is:

“Sina Weibo”: use started from 7:00, for 1 hour.

Both “Moji Weather” and “Gmail” are not used, and it may be considered that “Moji Weather” and “Gmail” have no feedback information.

Step S302. Update the use rule and the use model according to the feedback information of the second application program.

In this embodiment, after the feedback information of the second application program is acquired, the use rule and the use model may be updated according to the feedback information of the second application program, which may be updating a context information characteristic value of the second application program according to the context information generated when the terminal runs the second application program. For example, if it is found that the user often uses the recommended application program within a period of time, and a corresponding time characteristic may be added. Alternatively, the use rule and the use model may be updated according to the context information characteristic value of the second application program. For example, that the user chooses to use a recommended application program is used as a positive example, that the user does not choose to use a recommended application program is used as a negative example, and then the use rule and the use model are updated; or if the user seldom uses a recommended application program, it indicates that the current use rule and use model are not suitable for the user, and the use rule and use model may be adjusted to another use rule and use model, for example, the use rule may be adjusted using a new time statistical rule, and the use model may also be updated by changing a Bayes model to a linear regression model. Alternatively, the acquired current context information may be updated, for example, if a quantity that the user does not choose a previously recommended application program is relatively large, a type of collected current context information or a collecting frequency may be adjusted.

In a feasible implementation manner, the use rule and the use model may be adjusted according to the use time and use duration of the second application program. For example, the displayed recommended application programs are respectively “Sina Weibo”, “Moji Weather”, “Gmail”, and “Headlines Today”; feedback information of “Sina Weibo” includes use time 9:00 and use duration 1 hour, feedback information of “Moji Weather” includes use time 9:10 and use duration 5 minutes, feedback information of “Gmail” includes use time 9:15 and use duration 20 minutes, and feedback information of “Headlines Today” includes use time 9:05 and use duration 50 minutes. Therefore, a priority recommended for the second application program under a new preset condition is adjusted according to the feedback information of the second application program under a preset condition of 9:00 to 10:00, and the recommending priority of the second application program under the new preset condition is used as a use rule; or the machine training method is adjusted from the Bayes model to the linear regression model according to the feedback information of the second application program, so as to generate a use model again.

In this embodiment, a terminal acquires feedback information of a second application program, and updates a use rule and a use model according to the feedback information of the second application program, which further improves accuracy of predicting an application program.
