The embodiment of the disclosure provides a recommendation method of screen locking wallpaper. The recommendation method for lock screen wallpaper provided by the embodiment may be executed by a computing device, where the computing device may be implemented as software, or implemented as a combination of software and hardware, and the computing device may be integrally disposed in a server, a terminal device, or the like.

Referring to fig. 1, a flowchart illustrating steps of embodiment 1 of a method for recommending a screen locking wallpaper of the present disclosure is shown, which may specifically include the following steps:

step S1: acquiring historical operation information of a user on a mobile terminal; wherein the historical operation information comprises a plurality of historical operations with different weights.

In the embodiment of the present disclosure, the historical operation information of the user may be historical browsing operation of the user on the mobile terminal, and specifically, may be contents such as pictures, websites, videos, public numbers, articles, and the like browsed by the user on the mobile terminal; the historical operation information of the user may also be historical search operation of the user on the mobile terminal, and specifically, may be content searched by the user on the mobile terminal, such as content related to scenes such as "taishan", "west lake" and the like searched by the user in a search bar, or content related to movies such as "iron man", "crouching tiger dragon" and the like searched by the user; the historical operation information of the user may also be historical click operations of the user on the mobile terminal, specifically, click operations such as "like", "forward", "delete" and "save" of the user on the mobile terminal for the contents such as browsed pictures and articles; the historical operation information of the user may be a historical login operation of the user on the mobile terminal, and specifically, the historical operation information may be an application program such as a picture website and an article website which is logged in by the user on the mobile terminal.

In the embodiment of the disclosure, each historical operation has different weight, so that the specific operation of the user can be analyzed by integrating the weight, and the operation in a certain future time can be predicted based on the analysis.

For example, in the embodiment of the present disclosure, only pushing of the screen locking wallpaper to the user based on the historical browsing content of the user is considered, and naturally, since the screen locking wallpaper includes a picture part and a text part, in operations of browsing pictures, articles, videos, public numbers, websites and the like, the weights of browsing pictures and articles are higher than those of browsing videos, public numbers, websites and the like. For another example, in other embodiments, when the pushing of the screen locking wallpaper is performed on the user based on the historical browsing operation and the historical searching operation of the user, the "browsing" operation is naturally weighted higher than the "searching" operation due to the browsing characteristics of the screen locking wallpaper.

Specifically, as a first sub-embodiment of the present disclosure, the history browsing operation performed by the user includes a combination of one or more of the following history browsing operations:

on the mobile terminal, all contents browsed by the user;

and the duration and the number of times that the user browses a single content with similar attributes in all the contents browsed on the mobile terminal, wherein each historical browsing operation has different weight.

For ease of understanding, user a is illustrated in the following table:

TABLE 1 browsing situation of user A on the handset

From table 1, the specific browsing content of user a, and the specific duration and browsing times of each content can be clearly seen, from which the following conclusions can be drawn simply: user a has a greater interest in pictures and text.

Taking the picture content as an example, the picture browsing operation of the user a is further subdivided, as shown in the following table:

table 2 picture browsing situation of user a on mobile phone

Serial number	Picture classification	Landscape	Character	Construction of buildings	Sum of
						1	Duration (min)	7	5	3	15
2	Times (times)	1	1	1	3
						3	……	……	……	……	……

From table 2, it can be clearly seen that user a compares the mood with the landscape type pictures.

Taking the contents of the landscape pictures as an example, the browsing pictures of the user a are further subdivided, as shown in the following table:

table 3 picture browsing situation of user a on mobile phone

Serial number	Landscape picture	Mountain	Lake	Forest (forest)	Sum of
						1	Duration (min)	7	0	0	7
2	Times (times)	1	0	0	1
						3	……	……	……	……	……

From table 3, it can be clearly seen that although the landscape pictures contain a plurality of entity landscapes, the user a is more interested in pictures containing mountains.

In the method, since the pictures are generally continuous, two adjacent pictures often have a certain relationship, for example, pictures belonging to the same kind of landscape, including the same entity object, different posture pictures of the same star, and the like have the same attribute, or have similar attributes, and in order to reduce errors caused by calculation of browsing amount due to misoperation, indexes such as duration and the like for the next picture of the picture to be investigated are also taken as investigation indexes. For example, when the user a mistakenly enters a landscape picture a containing a "lake" and the next picture b adjacent to the landscape picture a also contains the "lake", the user a leaves the picture a and enters the next picture b. If the duration of browsing the picture b reaches 3min, the fact that the user A leaves the picture a is that the user A is mistaken for operation, and the user A likes the picture containing the lake; if the duration of browsing picture b is only 5s, it indicates that user A left picture b because he would not like the picture containing "lake". By the operation, the error value caused by misoperation of the user can be reduced, and the preset weight values of different browsing contents can be properly adjusted to better meet the actual situation.

In addition, in consideration of realistic factors of actual calculation difficulty, when different historical browsing operations performed by the user are comprehensively considered, different weights need to be set for all the alternative items. For example, it is understood that "the duration of browsing each of the individual contents" has a better reference meaning and a simpler calculation amount than "the duration of browsing the next individual content adjacent to the individual content", so that the former is weighted more heavily; the "duration of browsing a single content having the same attribute" has a better referential meaning and a simpler calculation amount than the "duration of browsing a single content having a similar attribute", so that the former is weighted more heavily. It should be noted that the weight of each historical operation can be adjusted according to the actual situation, so as to make it more realistic.

As a second sub-embodiment of the present disclosure, in step S1, the history operation includes a history search operation of the user on the mobile terminal, and the history search operation includes a combination of one or more of the following history search operations:

on the mobile terminal, all contents searched by the user;

wherein each of the historical search operations has a different weight.

As a third sub-embodiment of the present disclosure, in step S1, the historical click operation includes a historical click operation of the user on the mobile terminal, and the historical click operation includes a combination of one or more of the following historical click operations:

all contents clicked by the user on the mobile terminal;

clicking operation, which is performed by the user for all single contents, in all contents clicked on the mobile terminal; wherein the click operation comprises a click action for each of the individual contents, a duration of the same click action made for the same individual content, a number of times of the same click action made for the same individual content, a click action made for a next individual content adjacent to the individual content, a duration of the same click action made for a next individual content adjacent to the individual content, and a number of times of the same click action made for a next individual content adjacent to the individual content;

wherein the historical click operations have different weights.

As a fourth sub-embodiment of the present disclosure, in step S1, the history operation includes a history login operation of the user on the mobile terminal, and the history login operation includes a combination of one or more of the following history login operations:

on the mobile terminal, all platforms on which the user logs in;

in all platforms logged in on the mobile terminal, the user logs in for all single platforms; wherein the login operation comprises the duration of login to each of the single platforms, the number of times of login to the same single platform, the duration of login to a next single platform adjacent to the single platform, and the number of times of login to a next single platform adjacent to the single platform;

wherein each of the historical login operations has a different weight.

The second, third and fourth sub-embodiments can be understood in detail with reference to the first sub-embodiment, and are not described herein again. It should be reminded that the weights of the specific historical operations in the first, second, third and fourth sub-embodiments are different, and in this embodiment, the historical operation in the first sub-embodiment has a higher weight than the other three.

Step S2: analyzing all the historical operation information of the user on the mobile terminal, and selecting preset characteristics to perform tabular marking on the user.

As shown in fig. 2, specifically, in embodiment 2, step S2 includes the following sub-steps:

step S201: and arranging all the historical operation information of the user on the mobile terminal according to the time sequence to form an arrangement table.

In the embodiment of the present disclosure, a plurality of pieces of historical operation information are often performed on the mobile terminal by the user within a certain period of time, and for convenience of analysis, the historical operation information is arranged in a time sequence to form an arrangement table.

Step S202: and selecting at least three characteristics according to the arrangement table to mark the user, wherein the characteristics are selected from a preset characteristic set within a preset time, and the characteristics and the historical operation information of the user have associated description information.

In the embodiment of the present disclosure, when the arrangement table is received, at least three features having associated description information with the historical operation information of the user need to be selected from a preset feature set for a certain time.

Step S203: all of the features are sorted in descending order by weight to form a tabular marking for the user.

In the embodiment of the present disclosure, all the features are sorted in descending order according to the weights they have, so that the user can be marked in a tabular manner.

The following continues with the example of user a.

Firstly, the browsing contents of the user A at 13 and 14 are collated and tabulated as follows:

TABLE 4 browsing scenario for USER A at 13

Serial number	Picture classification	West lake	Mount Tai
				1	Duration (min)	40	20

TABLE 5 browsing scenario for user A at 14

Serial number	Picture classification	Thunder peak tower	Qingcheng mountain
				1	Duration (min)	45	15

In chronological order, an arrangement table is prepared by combining tables 4 and 5 as follows:

table 6 arrangement table for user a

Picture frame	West lake	Mount Tai	Thunder peak tower	Qingcheng mountain
					Duration (min)	40	20	45	15

Next, according to table 6, multiple features and their combinations can be selected from the feature set to mark the user, and in this embodiment, the marked features are: bai she Chuan (0.5), love (0.3) and Hangzhou (0.2), wherein the weight of each feature is in parentheses.

Finally, all the features are sorted in descending order according to the weight, and the tabulation mark made by the user A is as follows:

TABLE 7 tabulated markup of USER A

User A

White snake plaster (0.5)

Love (0.3)

Hangzhou (0.2)

Through the steps, the historical operation information of the user on the mobile terminal can be extracted and tabulated and marked, and a more convenient data basis is provided for the subsequent steps.

Step S3: summarizing all the tabular marks of the users, and making user pictures for the users to define the users.

In the embodiment of the present disclosure, all the tabular marks obtained in step S2 are collected to form big data for the user, and then the user is depicted by the big data to define the big data.

As shown in fig. 3, specifically, in embodiment 3, the step of creating a user representation for the user in step S3 includes the following sub-steps:

s301: acquiring all the characteristics and the respective corresponding weights for performing tabular marking on the user;

in this sub-step, the features and corresponding weights in the user's tabular marking may be obtained.

S302: sorting all the features in descending order according to the number of times the features appear;

in this sub-step, all features are ranked from high to low according to the number of occurrences of the features, and each weight is located directly below the corresponding feature.

S303: adding all weights owned by the same feature to obtain a plurality of weight sums, and performing descending order arrangement on all the weight sums;

in this sub-step, all weights of a feature in the same column are added to obtain a plurality of weight sums, and the weight sums are sorted in descending order.

S304: selecting the features with the same attribute to form an attribute feature set, and selecting the feature with the highest occurrence frequency in the attribute feature set as a representative feature of the attribute feature set;

in this sub-step, features having the same attribute are selected, these features are formed into an attribute feature set, and the feature with the highest occurrence number in the set is selected as a representative feature of this set.

S305: selecting a first weight and a corresponding representative feature as features of the user to make a user portrait of the user;

in this substep, the first weight and the corresponding representative feature are selected from among the plurality of representative features as the feature of the user, and the user image is created.

This step is described below, taking user a as an example.

After step S2, two tabular labels for user a can be obtained, as follows:

table 8 two tabular labels for user a

User A	White snake plaster (0.5)	Love (0.3)	Hangzhou (0.2)
				User A	Hangzhou (0.5)	Leifeng tower (0.3)	Love (0.2)

After substep S302, the following table is obtained:

TABLE 9

After substep S303, the following table is obtained:

watch 10

Feature(s)	Hangzhou province	Love	White snake conveyer	Thunder peak tower
					Number of times	2	2	1	1
Weight 1	0.2	0.3	0.5	0
					Weight 2	0.5	0.2	0	0.3
Weight sum	0.7	0.5	0.5	0.3

The following table was obtained after descending order:

TABLE 11

Feature(s)	Hangzhou province	Love	White snake conveyer	Thunder peak tower
					Weight sum	0.7	0.5	0.5	0.3

Through the substep S304, since the love, the white snake pass and the thunderpeak tower belong to the same attribute in the preset, an attribute feature set (love, white snake pass and thunderpeak tower) is obtained, and the representative features of the attribute feature set are as follows: love.

Through the substep S305, when there are a plurality of the representative features, the first weight and the corresponding representative feature are selected as the features of the user to perform user portrayal creation on the user.

For example, user A has a plurality of attribute feature sets, and naturally has a plurality of representative features, all of which are arranged in descending order by weight, and the first weight and the corresponding representative feature are selected as a reference for the user portrait.

Step S4: and pushing a screen locking wallpaper corresponding to the user image to the mobile terminal, wherein the screen locking wallpaper comprises a picture part and a character part and is used for displaying the screen locking wallpaper when the mobile terminal enters a screen locking state.

Specifically, as shown in fig. 4, in embodiment 4, in this step, the step of the mobile terminal selecting a lock screen wallpaper corresponding to the user portrait in a lock screen wallpaper set includes:

substep S501: determining historical screen locking wallpaper of a user according to historical operation information of the user;

substep S502: determining a screen locking wallpaper with similar attributes to the historical screen locking wallpaper, and forming a screen locking wallpaper set of the user, wherein the screen locking wallpaper in the screen locking wallpaper set has associated description information;

substep S503: determining a target screen locking wallpaper from the screen locking wallpaper set;

substep S504: and recommending the description information associated with the target lock screen wallpaper to the user.

In the embodiment of the present disclosure, this is still explained by using the user a.

Firstly, according to the browsing operation of a user A on a mobile terminal on a West lake picture, the historical screen locking wallpaper of the user A can be determined to be a picture of the West lake; then, the lock screen wallpaper with similar attributes to the "west lake" can be used as a lock screen wallpaper set, for example, pictures of the "west lake", "hangzhou", and the like can be included; these pictures are then recommended to the user from the lock screen wallpaper set.

As shown in fig. 5, further, in embodiment 5, the sub-step S502 further includes the following steps:

substep S5021, obtaining a plurality of candidate screen locking wallpapers;

step S5022, calculating the similarity between candidate screen locking wallpaper in the candidate screen locking wallpapers and the historical screen locking wallpaper in sequence;

and a substep S5023, adopting the candidate screen locking wallpaper with the similarity larger than a preset threshold value and the historical screen locking wallpaper to generate a screen locking wallpaper set of the user.

This step is explained by continuing with the example of user a described above.

When the screen locking wallpaper with the similar attribute to that of the 'west lake' picture is selected, various choices can be provided, such as 'Hangzhou' picture, 'lake' picture, 'sushi' picture, 'white snake' picture and the like. For convenience of selection, the similarity between the pictures and the 'West lake' is calculated for the pictures respectively, when the similarity exceeds a certain value, the pictures and the 'West lake' pictures are relatively high, the pictures can be used as candidate screen locking wallpaper, and the candidate screen locking wallpaper and historical screen locking wallpaper browsed by the user A before form a screen locking wallpaper set together so as to be recommended to the user.

As shown in fig. 6, further, in embodiment 6, the sub-step S5022 includes the following steps:
