The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions of other terms will be given in the description below.

It should be noted that concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or interdependence.

It should be noted that the modifications of "a" and "a plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless the context clearly indicates otherwise, they should be understood as "one or a plurality of". multiple".

The names of messages or information exchanged between multiple devices in the embodiments of the present disclosure are only for illustrative purposes, and are not intended to limit the scope of these messages or information.

First, the application scenarios of the present disclosure are introduced. In one application scenario of the present disclosure, different countries may have media files with the same name. For example, both country A and country B have media files named "XX". When a user searches for media files named "XX" , in the present disclosure, the display order of the media files named "XX" in country A and the media files named "XX" in country B can be determined according to the usage preferences of users in different countries.

Of course, the application scenarios of the present disclosure are not limited to the above scenarios based on user search and media files with the same name. For example, when pushing media files that may be of interest to users, such as multiple newly released media files, different media files may come from different countries. , to determine the display order of multiple media files pushed to the user.

Fig. 1 is a flow chart of a method for displaying media files according to an exemplary embodiment. The method can be applied to an electronic device with processing capability, such as a terminal, a server, and the like. As shown in FIG. 1 , the method may include S101 to S104.

In S101, a plurality of target media files to be displayed to a target user and a country corresponding to each target media file are determined.

In one embodiment, the target media file may be a media file related to the retrieval information determined according to the retrieval information input by the target user. For example, the retrieval information input by the target user may be the name of a media file, such as the title of a song, and the multiple target media files may be multiple media files with the same or similar names. In another embodiment, the target media file may be a media file that may be of interest to the user, such as a newly released media file, or a popular media file.

Different target media files may correspond to different countries, wherein the country corresponding to the target media file may be the country where the target media file is first published, that is, the country where the target media file is first published. For example, if the target media file a is first released in country A, the country corresponding to the target media file a may be country A.

In S102, the country where the target user is located is determined.

Wherein, the country where the target user is located may be determined according to the current location information of the target user.

In S103, the similarity feature information corresponding to each target media file is acquired.

For example, users in different countries may have different preferences for music styles. For example, users in some countries prefer to choose soothing music, and users in some countries prefer to choose rock music. That is, users in different countries have different preferences for media files. Preferences may vary. If users in two countries both prefer soothing music, it can indicate that users in these two countries have similar preferences for using media files. If users in one country prefer soothing music, and users in the other country prefer rock music, it can indicate that users in these two countries have relatively large differences in their preferences for using media files. It should be noted that the above-mentioned use preference for media files represented by the user's preference for music genres is only an exemplary explanation, and does not constitute a limitation to the embodiments of the present disclosure.

The similarity feature information corresponding to the target media file can be used to represent the similarity in the usage preference of the media file between the user in the country where the target user is located and the user in the country corresponding to the target media file. For example, the country corresponding to the target media file a is country A, the country corresponding to the target media file b is country B, and the country where the target user is located is country C. If users in country C and users in country A have similar usage preferences for media files, the similarity feature information corresponding to the target media file a is relatively high. If users in country C and users in country B have a relatively large difference in using preferences for media files, the similarity feature information corresponding to the target media file b is relatively low.

In S104, the display order of the multiple target media files is determined according to the similarity feature information.

The target user may prefer to select target media files with high corresponding similarity feature information. Therefore, when determining the display order of multiple target media files, the corresponding target media files with high similarity feature information can be ranked in the corresponding target media files. Before the target media file with low similarity feature information.

Following the above example, users in country C where the target user is located and users in country A have more similar usage preferences for media files. Therefore, the target user may prefer to select target media file a. When determining the display order of multiple target media files. , the target media file a can be arranged before the target media file b.

Through the above technical solution, the target media file is a media file to be displayed to the target user, and the similarity feature information corresponding to the target media file can be used to characterize the relationship between users in the country where the target user is located and users in the country corresponding to the target media file. Similarity of usage preferences for media files. The target user may prefer to select target media files with high corresponding similarity feature information. Therefore, when determining the display order of multiple target media files, the corresponding target media files with high similarity feature information can be ranked in the corresponding target media files. Before the target media file with low similarity feature information. In this way, when multiple target media files are displayed to the user, the user's preference for using media files in different countries can be considered, so that the user can first browse to the target media file he prefers to select, instead of selecting the multiple target media files in random order. The files are sorted, so that the display order of the target media files is more in line with the expectations of the target user, the experience of the target user is improved, and the rationality of the display order of the target media files is improved.

In the present disclosure, obtaining the similarity feature information corresponding to each target media file in S103 may include:

For each target media file, according to the first distance between the target usage preference information for the media file by the user in the country where the target user is located and the target usage preference information for the media file by the user in the country corresponding to the target media file, determine the target media file. Similarity feature information corresponding to the target media file.

The target usage preference information can be used to characterize the user's usage preference for media files in a country. In one embodiment, the target usage preference information may be represented in the form of a vector, wherein the dimension of the vector may be preset, for example, may be set to any dimension between 32 dimensions and 128 dimensions. The first distance between the target usage preference information may be an Euclidean distance between vectors.

If the user preferences of the media files in the two countries are more similar, the target usage preference information corresponding to the two countries is closer, and the first distance between the target usage preference information is smaller. For example, for example, the reciprocal of the first distance may be used as similarity feature information corresponding to the target media file. Wherein, the smaller the first distance, the greater the corresponding similarity feature information, which can indicate that the user in the country where the target user is located and the user in the country corresponding to the target media file have higher similarity in the usage preference of the media file.

In the present disclosure, the target usage preference information corresponding to each country may be pre-trained, for example, pre-trained according to the historical usage of media files by users in each country. In an optional implementation manner, the similarity feature information corresponding to the target media file may be predetermined, for example, may be predetermined according to the target usage preference information corresponding to the trained country, and stored in the terminal or server. The server can directly obtain the similarity feature information. In another optional implementation manner, the similarity feature information corresponding to the target media file may also be determined after S102 according to the pre-trained target usage preference information corresponding to the country.

Fig. 2 is a flowchart of a method for obtaining target usage preference information according to an exemplary embodiment. As shown in FIG. 2, the method may include S201-S204.

In S201, for each media file, historical usage information of the media file in multiple target countries is acquired.

The media files may be selected songs, music, music clips, etc., and may also include the above-mentioned target media files to be displayed to the user. Which countries are used as target countries may be preset, and the target countries may include the country where the target user is located and the country corresponding to the target media file.

The historical usage information of the media file in the target country may be the usage information of the media file by the users of the target country within a preset historical period (eg, the past week or month). Exemplarily, the historical usage information may include, for example, the usage amount of the media file, the completion amount of playing the media file, and the number of times the media file is used as the background media file. Wherein, the usage amount of the media file may include the number of times the media file is played, the number of times it is searched, and the like. The play completion amount of the media file may refer to the number of times the media file is played and completed. The number of times the media file is used as the background media file may refer to the number of times that the media file is set by the user as the ringtone of the mobile phone, the background music of the short video, and the like.

In S202, according to the historical usage information of the media file in each target country, the positive country and the negative country of the media file are respectively determined.

The positive example country may be a target country that satisfies the preset usage condition of the media file, and the negative example country may be the target country that does not meet the preset usage condition of the media file. Wherein, the preset usage condition may include at least one of the following: the usage amount of the media file is greater than the preset usage amount threshold; the playback completion amount of the media file is greater than the preset playback amount threshold; the number of times the media file is used as the background media file is greater than the preset usage amount Quantity threshold. Wherein, the preset usage threshold, the preset playback threshold, and the preset quantity threshold can all be set in advance, and the present disclosure does not specifically limit the value of each threshold. Moreover, for different media files, the preset usage conditions may be the same or different, which is also not specifically limited in the present disclosure.

The preset usage conditions may include one or more of the above conditions. When including more than one of the above conditions, when determining a positive country, the target country may satisfy the multiple conditions at the same time. The country is a positive example country of the media file, or, if the target country satisfies one of a plurality of conditions, the target country can be regarded as a positive example country of the media file. When determining a negative country, if none of the target countries satisfy the multiple conditions, the target country may be regarded as a negative country of the media file.

In addition, when determining the negative country of the media file, in addition to considering whether the target country satisfies the preset usage conditions of the media file, the overall usage of the media file by the target country can also be considered, that is, the users in this country The total amount of files used. If the target country does not meet the preset usage conditions of the media file, and the total amount of media files used by users in the target country is relatively large, the target country may be regarded as a negative example country. The main reason is that if users in the target country use a large amount of media files, the probability of the target country being a positive example country is high, and the probability of being a negative example country is small. In order to balance the target country as a positive example country and the probability of a negative country, the target country can be regarded as a negative country.

For example, for media file c, country A and country C both meet the preset usage conditions for media file c, and country B does not meet the preset usage conditions for media file c, then country A and country C can be used as media file c. The positive example country of , takes country B as the negative example country of media file c.

In S203, at least one tuple corresponding to the media file is established. Wherein, each tuple may include a plurality of positive example countries of the media file and at least one negative example country of the media file.

The present disclosure does not specifically limit the number of positive countries and the number of negative countries in the multi-group.

In S204, the usage preference information of each target country is iteratively updated according to the tuple and the objective function, so as to obtain the target usage preference information.

For each media file, after establishing at least one tuple corresponding to the media file, the usage preference information of each target country can be iteratively updated according to the established tuple and objective function, so as to obtain the target corresponding to each target country. Use preference information. In the present disclosure, each tuple can be used to iteratively update the usage preference information of the countries involved in the tuple, and the iterative updating process is a process of continuously optimizing the usage preference information. As the number of iterative updates increases, the usage preference information is continuously optimized, which can make the final target usage preference information more accurate and better reflect the usage preference of users in the target country for media files.

Wherein, each target country may have its own initial usage preference information, and the initial usage preference information may be preset, for example, may be represented in the form of a vector. The initial usage preference information of each target country may be the same or different, which is not specifically limited in the present disclosure.

An exemplary implementation of iteratively updating the usage preference information of each target country according to the tuple and the objective function in the above S204 may be shown in FIG. 3 , including S301 to S306 .

In S301, one of the tuples from the untraversed tuples is obtained as the target tuple, and the target parameter corresponding to the target tuple is determined according to the current usage preference information and objective function of the country involved in the target tuple.

The target tuple can be any tuple in the untraversed tuple. For example, in an optional embodiment of the present disclosure, the multi-tuple includes two positive countries and one negative country. This step S301 may include:

Determine the second distance between the current usage preference information of two positive example countries in the target tuple, and the current usage preference information of one of the positive example countries in the target tuple and the current usage preference information of the negative example country in the target tuple The third distance between the preference information is used; the target parameter is calculated according to the second distance, the third distance and the target function. The usage preference information may be represented in the form of vectors, and the second distance and the third distance may be Euclidean distances between the vectors.

Illustratively, the objective function can be:

Y=D1-min(β, D2)

Wherein, Y represents the target parameter, D1 represents the second distance, D2 represents the third distance, and β represents the preset distance threshold.

Following the above example, country A and country C can be used as positive example countries for media file c, and country B can be used as a negative example country for media file c. One of the tuple corresponding to the media file c may be (country A, country C, country B). For example, using the tuple as the target tuple, the second distance between the current usage preference information of country A and the current usage preference information of country C, as well as the current usage preference information of country A and the current usage preference information of country B can be calculated the third distance between. Then, the second distance and the third distance are input into the objective function, and the corresponding objective parameters can be obtained.

In S302, it is determined whether the target parameter satisfies a preset update condition. If satisfied, execute S303; if not, execute S304.

For the positive example countries of a media file, these positive example countries all meet the preset usage conditions of the media file, and the usage preferences for the media file are similar, so the above-mentioned second distance should be sufficiently small. However, countries with positive examples and countries with negative examples have different preferences for using the media file, so the above-mentioned third distance should be large enough. In this way, the purpose of iterative optimization can be transformed to minimize the target parameters.

The preset update condition may be that the target parameter is greater than a preset value, and if the target parameter is greater than the preset value, it can indicate that the target parameter satisfies the preset update condition. If the target parameter is less than or equal to the preset value, it can be represented that the target parameter does not meet the preset update condition.

In S303, the current usage preference information of the country involved in the target multigroup is adjusted.

When the target parameter satisfies the preset update condition, the current usage preference information of the country involved in the target tuple can be adjusted according to the difference between the target parameter and the preset value, for example, the gradient descent method can be used to adjust , so that the country's current usage preference information can better reflect the country's users' preference for using media files.

In S304, the current usage preference information of the country involved in the target tuple is kept unchanged.

If the target parameter does not meet the preset update condition, the current usage preference information of the country involved in the target tuple may not be updated.

In S305, it is determined whether there is an untraversed tuple. In the case of existence, return to S301; in the case of no existence, execute S306.

In S306, the current usage preference information of the target country is used as the target usage preference information of the target country.

If there is an untraversed tuple, S301 can be re-executed. In the present disclosure, each tuple can be used to iteratively update the usage preference information of the countries involved. The more precise the preference information. In the case that all tuples have been traversed, that is, the iterative update of the country's usage preference information is completed, and the current usage preference information can be used as the target usage preference information of the target country.

Through the above technical solution, a tuple corresponding to the media file can be established for each media file, and each tuple can include multiple positive countries and at least one negative country. According to the tuple and the objective function, by iteratively updating the country's usage preference information, the target usage preference information corresponding to each country can be trained. As the usage preference information is iteratively updated more times, the final target usage preference information is more accurate, and can better reflect the usage preference of users in the target country for media files.

When the method for displaying media files provided by the present disclosure is applied to a terminal, the method may further include:

Display multiple target media files in display order.

The terminal may be a terminal device used by the target user, for example, a device such as a smart phone, a tablet computer, and a personal computer. After determining the display order of the multiple media files, the terminal may display the multiple target media files according to the display order, so that the user first browses to the target media file that he or she may prefer to select.

When the method for presenting media files provided by the present disclosure is applied to a server, the method may further include:

The determination result of the presentation order is sent to the terminal, so that the terminal presents a plurality of target media files according to the presentation order.

After determining the display sequence of the multiple target media files, the server may send the determination result of the display sequence to the terminal used by the target user. After receiving the determination result of the display order, the terminal can display multiple target media files according to the display order.

Based on the same inventive concept, the present disclosure further provides an apparatus for displaying media files. FIG. 4 is a block diagram of an apparatus for displaying media files according to an exemplary embodiment. As shown in FIG. 4, the apparatus 400 may include:

The first determining module 401 is configured to determine a plurality of target media files to be displayed to a target user and a country corresponding to each of the target media files;

The obtaining module 403 is configured to obtain similarity feature information corresponding to each of the target media files, where the similarity feature information is used to represent the user in the country where the target user is located and the target media file. Similarity of usage preferences for media files among users in a country;

The third determining module 404 is configured to determine the display order of the multiple target media files according to the similarity feature information.

Through the above technical solution, the target media file is a media file to be displayed to the target user, and the similarity feature information corresponding to the target media file can be used to characterize the relationship between users in the country where the target user is located and users in the country corresponding to the target media file. Similarity of usage preferences for media files. The target user may prefer to select target media files with high corresponding similarity feature information. Therefore, when determining the display order of multiple target media files, the corresponding target media files with high similarity feature information can be ranked in the corresponding target media files. Before the target media file with low similarity feature information. In this way, when multiple target media files are displayed to the user, the user's preference for using media files in different countries can be considered, so that the user can first browse to the target media file he prefers to select, instead of selecting the multiple target media files in random order. The files are sorted, so that the display order of the target media files is more in line with the expectations of the target user, the experience of the target user is improved, and the rationality of the display order of the target media files is improved.

Optionally, the obtaining module includes: a determining sub-module configured to, for each target media file, use the target media file according to the target usage preference information of the user in the country where the target user is located and the target media file. The first distance between the target usage preference information of the media file by the users in the country corresponding to the file determines the similarity feature information corresponding to the target media file.

Optionally, the apparatus 400 may further include: a presentation module configured to present the multiple target media files in the presentation sequence; or a sending module configured to transmit the presentation to the terminal The result of the determination of the order is to display the plurality of target media files by the terminal according to the display order.
