Description
Technical Field
The present disclosure relates to the field of computer processing technologies, and in particular, to a sorting method, an apparatus, an electronic device, and a computer-readable storage medium.
Background
With the rapid development of mobile internet technology, mobile terminals such as smart phones and tablet computers have become indispensable components in life. The user can obtain and browse a great deal of information through the mobile terminal, and the information comprises characters, pictures, music, videos and the like. In recent years, videos meet fragmented reading and information sharing requirements of users with rich information coverage and diversified presentation, and are therefore widely sought after.
When a user browses a video website, a keyword is usually input as a search request, the video website pushes a group of video files to the user according to the search request of the user, the video files are ordered according to a certain rule and displayed to the user, and the user can click to play an interested video file. One existing ranking method is to score video files based on their click models (e.g., calculate the click rate of each video file), rank and present to the user according to the score of each video file.
The ranking method based on the click model generally considers that a user clicks on a video, which indicates that the video is related or enjoyed by the user. However, the ranking method based on the click model cannot accurately reflect the relevance of the video or the user's preference for the video. For example, a user may turn a video on, find its content irrelevant or uninteresting, and then turn the video off soon. For another example, the user may click on the video due to a malfunction, and then close quickly. In the above case, although the actual content of the video is not relevant, the click behavior is still used as valid statistical data in the ranking method based on the click model. Therefore, the sequencing result of the existing sequencing method is not accurate enough.

As mentioned above, currently, only the case where the play items (e.g. video, audio files) are clicked is considered, and the play items are scored and sorted by the click model, which may cause inaccurate sorting results. One typical scenario is to sort the video files based on click-through rate. For example, a video file is exposed (i.e., displayed in the search results of the user) 100 times through the search request of the user, and if 60 users click on the video file, the click rate of the video file is 60%, and the relevance or popularity of the video file is generally considered to be 60%. However, there may be 10 users who close the video file immediately after clicking, but do not really play the content of the video file, that is, the true relevance or popularity of the video file should be lower than 60%, and this cannot be really reflected by the click rate.
In order to improve the accuracy of the sequencing of the video files, the playing time of the video files by the user needs to be considered. One possible solution is to determine the relevancy or popularity of the video file according to the proportion of the playing time length of the video file to the total time length, that is, the relevancy or popularity of the video file is considered to be higher when the proportion of the playing time length to the total time length is higher. However, such a calculation is not fair for video files of different lengths.
On one hand, for video files with different total duration but the same proportion of the playing duration to the total duration, the proportion often cannot truly represent the relevance or popularity of the video files. For example, for a video file with a total duration of 4 seconds, the user may click to play 2 seconds and then immediately close the video file because the video file is uninteresting, and the playing duration accounts for 50% of the total duration. For a video file with a total duration of 10 seconds, the user may close the video file after watching it for 5 seconds, but the playing duration is also 50% of the total duration. That is, the user may have different attitudes with respect to the video files with different total durations, but cannot display the video files according to the ratio of the playing duration to the total duration.
On the other hand, for shorter video files, the playing time length is usually larger in proportion. For example, a video file with a total duration of 4 seconds is clicked by a user to play for 2 seconds, the playing duration accounts for 50% of the total duration, while a video file with a total duration of 20 seconds is also clicked by a user to play for 2 seconds, and the playing duration accounts for only 10% of the total duration. However, for the two video files with different lengths, the user's operation may be the same, for example, both are closed when playing for 2 seconds because of being uninteresting, but this situation cannot be accurately reflected only by the ratio of the playing time length to the total time length.
Therefore, when the play items are sorted, not only the click condition and the play condition of the play items need to be considered comprehensively, but also the influence of the total duration of the play items needs to be considered fully, so that the sorting result of the play items is more reliable.
The sorting method provided by the embodiment may be executed by a sorting apparatus, which may be implemented as software, may be implemented as hardware, or may be implemented as a combination of software and hardware, for example, the sorting apparatus includes a computer device, so that the sorting method provided by the embodiment of the present disclosure is executed by the computer device.
It can be understood that in the sorting method provided in this embodiment, the play items may be video files or audio files.
Fig. 1 is a flowchart of an embodiment of a sorting method provided in an embodiment of the present disclosure, and the sorting method provided in an embodiment of the present disclosure may be executed by the sorting apparatus described above.
As shown in fig. 1, the sorting method of the embodiment of the present disclosure includes the following steps:
step S101, determining the total time length and the playing time length of the playing item.
Recording the total time length of the playing item as Spanq-dAnd the playing Duration is recorded as Durationq-d. It is understood that the same play item is exposed by the search request of the user, and there may be a plurality of users clicking and playing the play item, or one user may click and play the play item multiple times. Therefore, for the play item played for the ith time, the time length of the play item actually played is recorded as Durationq-d，iDuration of each playq-d，iMay be the same or different.
The user can play the entire play item, or only play a part of the play item, i.e. 0 ≦ Durationq-d，i≤Spanq-d。
And step S102, calculating the playing score of the playing item based on a Wilson interval algorithm according to the total duration and the playing duration.
In step S102, for the ith play of the play item, the play Duration is determined according to the following formulaq-d，iWith the total duration Span of said play itemq-dRatio p ofi：
As mentioned earlier, only the ratio p is usediIt is unreliable to measure the playing condition of the play item as a playing score, for example: different playing situations may have the same ratio pi(ii) a Different play items have different overall durations, while shorter play items generally have a higher ratio pi。
Therefore, the ratio p is calculated in step S102 using the wilson interval algorithmiAs a parameter of the wilson interval algorithm, calculating a play Score of the ith played play itemi. The wilson interval algorithm is an algorithm for calculating the reliability of the probability P, and comprehensively considers the probability P and the number of samples. Specifically, the play Score for the ith play of the playitem is calculated according to the following formulai：
Wherein the content of the first and second substances,
denotes the z statistic at a confidence level a, which is a constant and n is the total duration of the play item, i.e. n-Spanq-d。
The confidence level alpha is typically chosen to be 0.95. It will be appreciated that the confidence level a may also take any other value possible.
In an alternative embodiment, the lower limit of the Wilson interval is taken as the play Score Score of the ith played play itemi。
For the sake of understanding, the calculation of the play score based on the wilson interval algorithm is described by way of example. For example, for a video with a total duration of 4 seconds, the user plays for 2 seconds, and the ratio p is 2/4-0.5; for another video with a total duration of 10 seconds, the user plays for 5 seconds, the ratio p is also 5/10 ═ 0.5, and the relevance or popularity of the video cannot be judged only by the ratio p. At this time, this problem can be solved by a play score based on the wilson interval.
The confidence level α is taken to be 0.95, corresponding to a z statistic of 1.96. For the video with the total duration of 4 seconds, the corresponding playing Score is4sComprises the following steps:
calculated, Score4sAbout 0.15.
For a video with a total duration of 10 seconds, the corresponding playing Score is10sComprises the following steps:
calculated, Score10sAbout 0.24. Therefore, under the condition that the ratio of the playing time length to the total time length is 0.5, the playing fraction of the video with the total time length of 10 seconds is higher than that of the video with the total time length of 4 seconds, so that the interference caused by the playing randomness of short video misoperation and the like is weakened.
Step S103, determining the sorting score of the play item at least according to the play score of the play item.
In an alternative embodiment, the playltems are clicked and played m times, that is, each time the playltems are played, a play Score is generatediThen, the play Score of the play item is ScoreplayA function of a play score for each of the play items:
can broadcast the contentThe play Score of a play item ScoreplayDetermining as a parameter a ranking Score for the playitemrank：
Wherein the content of the first and second substances,
represents the ranking Score ScorerankScore for the playbackplayAs a function of (c).
In another alternative embodiment, the click situation and the play situation of the play item are taken into account. Following the above example, when the play item is clicked and played m times, the click Score of the play item is determined according to the click model of the play itemclickComprises the following steps:
wherein, Imprq-dThe exposure times of the play items are Impr of m being less than or equal toq-d。
According to the play Score of the play itemplayAnd the click ScoreclickDetermining the ranking score of the playitem. The weights ω of the play scores may be determined separately1And the weight ω of the click score2Then the ranking Score of the play item ScorerankComprises the following steps:
Scorerank＝ω1Scoreplay+ω2Scoreclick
it is worth noting that, in the embodiment of the present disclosure, a person skilled in the art can apply the weight ω to1And ω2High or low of is defined. For example, the weight includes a number or a score, it may be defined that the greater the number or the score, the higher the weight, and then in step S103, increasing the weight of the play score or the click score means increasing the number of the play score or the click scoreA word or score; it may also be defined that the smaller the number or score is, the higher the weight is, and then in step S103, the higher the weight of the play score or the click score means the lower the number or score of the play score or the click score.
And step S104, sequencing the play items according to the sequencing scores of the play items.
It is understood that after the ranking score of each of the playitems is obtained, the playitems may be ranked in order from high to low and displayed to the user through the terminal page.
In the embodiment of the disclosure, the playing score of the playing item is determined through a Wilson interval algorithm, and the sorting score of the playing item is determined at least according to the playing score, so that the playing duration factor of the user to the playing item can be considered when the playing item is sorted, the sorting accuracy and reasonableness are improved, and the user experience is improved.

Wherein, the determining module 201 is configured to determine the total duration Span of the playing itemq-dAnd a play Durationq-d，iWherein the playing Durationq-d，iThe time length of the ith playing of the playing item is set, and the playing time length satisfies the Duration of not less than 0q-d，i≤Spanq-d(ii) a The calculating module 202 is configured to calculate the total duration Span according to the total duration Spanq-dAnd the playback Durationq-d，iCalculating the playing score of the playing item based on a Wilson interval algorithm; the determining module 201 is further configured to determine a ranking score of the playitem according to at least a play score of the playitem; the sorting module 203 is configured to sort the playitems according to the sorting scores of the playitems.
