Description

Technical Field

The invention belongs to the technical field of computers, and particularly relates to a video satisfaction degree determining method and device.

Background

With the continuous development of computer technology, more and more videos are available in a video platform, and video search is also widely applied. In video searching, the mobile terminal will often rank the search results based on the user's satisfaction with each video in the search results. As an important parameter of video sequencing, how to determine the satisfaction degree of a user on a video becomes a problem of great attention.

In the prior art, it is common to determine whether the user is satisfied with the video based on a fixed duration threshold of 30 seconds (second, s). Specifically, when the click time of the user on the video is greater than 30s, it is determined that the user is satisfied with the video.

However, since the duration of each video is different, the click duration of a video with a longer duration is easy to reach 30s, but the user cannot be satisfied with the video when watching the video for 30s, and then the video unsatisfactory to the user is determined to be the video satisfactory to the user, and accordingly, for the video with a shorter duration, the video duration may not reach 30s, the click duration of the user for the video for this type is difficult to reach the fixed duration threshold, and then the video satisfactory to the user is determined to be the video unsatisfactory to the user, so that the video satisfaction determination method in the prior art is low in accuracy and poor in determination effect.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Example one

Fig. 1 is a flowchart illustrating steps of a video satisfaction determining method according to an embodiment of the present invention, where as shown in fig. 1, the method may include:

step 101, obtaining a duration parameter of a playing operation of a target user on a target video.

In the embodiment of the present invention, the duration parameter may include a playing duration or a click duration of the target video in the playing operation of the target user. The playing time length refers to the time length between the time point when the target video is opened by the target user and the time point when the target video is closed by the target user, and the clicking time length refers to the time length between the time point when the target video is opened by the target user and the time point of the next action of the target user.

For example, suppose the user "Zhang three" is 8 in 1/2/2018: 00 video a is opened, playing is started, and then, zhang is again 8: 20 opens video B and plays video a and video B simultaneously until destination 8: 22 close video a, it can be determined that the click duration of video a is 20 minutes and the play duration is 22 minutes.

Specifically, when the duration parameter is the playing duration, a behavior log generated when a target user opens a target video can be acquired from a background of a video application, a timestamp in the behavior log is extracted, so that a time point when the target video is opened by the target user is obtained, the behavior log generated when the target user closes the target video is acquired, the timestamp in the behavior log is extracted, so that a time point when the target video is closed by the target user is obtained, a duration between the time point when the target video is opened and the time point when the target video is closed is calculated, and a duration parameter is obtained; correspondingly, when the duration parameter is the click duration, a behavior log generated when the target video is opened by the target user may be obtained from a background of the video application, a timestamp in the behavior log is extracted, a time point at which the target video is opened by the target user is further obtained, a next behavior of the target user is obtained, the generated behavior log, the timestamp in the behavior log is extracted, a time point at which the target user executes the next behavior is further obtained, a duration between the time point at which the target video is opened and the time point at which the next behavior is executed is calculated, and a duration parameter is further obtained.

Step 102, determining a duration parameter threshold corresponding to the target video according to the attribute parameters of the target video and at least one preset duration parameter threshold function.

In this embodiment of the present invention, the attribute parameter at least includes a duration of the target video, and the attribute parameter may further include a type of a playing end corresponding to the target video in a playing operation. Further, the preset duration parameter threshold function may be a predetermined function that may reflect a correspondence between the duration of the video and the duration parameter threshold, where in the preset duration parameter threshold function, the duration parameter threshold is a dependent variable, and the duration of the video is an independent variable. Specifically, when the attribute parameter only includes the time length of the target video, a preset time length parameter threshold function may be predetermined; when the attribute parameters include the duration of the target video and the type of the playing end corresponding to the target video in the playing operation, preset duration parameter threshold functions corresponding to different types of the playing end can be predetermined.

Specifically, the attribute parameters of different target videos may be different, and therefore, the duration parameter threshold corresponding to each target video may be different, and the duration parameter threshold corresponding to each target video is determined according to the attribute parameters of the target video, and therefore, the duration parameter threshold can represent the duration parameter when the target user is satisfied with the target video.

And 103, determining whether the user is satisfied with the target video according to the time length parameter threshold and the time length parameter.

In the embodiment of the invention, when the duration parameter is not less than the duration parameter threshold, the satisfaction of the user on the target video can be determined. The time length parameter threshold is determined according to the attribute parameters of the target video and can represent the time length parameter when the target user is satisfied with the target video, so that whether the target user is satisfied with the target video can be more accurately determined by taking the time length parameter threshold as a judgment basis.

In summary, in the method for determining video satisfaction provided in the embodiment of the present invention, a duration parameter of a playing operation performed on a target video by a target user is first obtained, then a duration parameter threshold corresponding to the target video is determined according to an attribute parameter of the target video and at least one preset duration parameter threshold function, and finally, whether the target user is satisfied with the target video is determined according to the duration parameter threshold and the duration parameter.

Example two

Fig. 2-1 is a flowchart illustrating steps of a video satisfaction determining method according to a second embodiment of the present invention, and as shown in fig. 2-1, the method may include:

step 201, determining sample historical playing information corresponding to each sample video according to a sample log corresponding to each sample video.

Specifically, step 201 may include:

step 2011, at least one piece of historical playing information corresponding to each sample video is determined according to the sample log corresponding to each sample video.

In this step, the historical playing information may at least include the duration of the sample video and a historical duration parameter, where the historical duration parameter may include a historical playing duration or a historical click duration. Further, the history playing information may also include other content, for example, a history playing end type of the sample video is included, each piece of history playing information corresponding to each sample video represents a record of the sample video played by the user, and the history playing information may represent a type of playing end and a specific click duration or a specific playing duration of the sample video during the playing.

Specifically, when determining at least one piece of historical play information corresponding to each sample video, a log corresponding to the sample video may be obtained from a background of a video platform to obtain a sample log corresponding to the video, where the log corresponding to the sample video may be all logs accumulated since the sample video enters the video platform, or may be a log accumulated in a certain time period by the sample video, which is not limited in this embodiment of the present invention. Then, each sample log can be analyzed one by one according to the time sequence generated by the sample logs, generally, a user can generate logs aiming at each behavior of a video, and the logs generally comprise a click time point, an ID of a clicked video, a type of a playing end corresponding to the clicked video and a time length of the clicked video. For example, taking the example that the historical playing information includes the historical playing end type of the sample video, the time length of the sample video, and the historical time length parameter is the playing time length, it is assumed that 20, which indicates that the sample video a is in the 1, 15, purpose of 2018 in the first sample log 1 corresponding to the sample video a: 00 is opened at the mobile terminal, and the second sample log 2 corresponding to the sample video a represents 20 of the sample video a in 2018, 1, month and 15 meshes: 02 is turned off at the mobile terminal, historical playing information a corresponding to the sample video a may be generated, and assuming that the ID of the sample video a is 001 and the duration is 40 minutes, the historical playing information a may be represented as:

a play _ id (mobile end) \ t doc _ id (001) \ t duration (40min) \ t play (2 min);

wherein, the playlist _ ID represents the playing end type of the sample video in the playing, doc _ ID represents the ID of the sample video, duration represents the duration of the sample video, and playtime represents the playing duration of the sample video in the playing.

Step 2012, at most m pieces of historical play information corresponding to each sample video are obtained, and the historical play information of the sample corresponding to each sample video is obtained.

In this step, m is the maximum number of pieces of sample historical playing information corresponding to each predefined sample video. The specific numerical value of m may be set by a developer according to actual experience, and since some sample videos have a large number of click behaviors and further have a corresponding large number of sample logs, compared with sample videos with fewer click behaviors, the proportion occupied by the historical play information of the sample videos with a large number of click behaviors is large, so that data distribution is unbalanced, and further, the preset duration function determined according to the data is inaccurate.

Specifically, during the obtaining, if the number of the pieces of all the historical playing information corresponding to the sample video is not greater than m, obtaining all the historical playing information corresponding to the sample video to obtain the sample historical playing information corresponding to the sample video, and if the number of the pieces of all the historical playing information corresponding to the sample video is greater than m, randomly selecting m pieces of the historical playing information from all the historical playing information corresponding to the sample video to serve as the sample historical playing information corresponding to the sample video. Of course, other obtaining manners may also be adopted, and the embodiment of the present invention is not limited thereto as long as the number of selected pieces is not greater than m.

Step 202, based on the duration of each sample video, dividing the sample historical playing information corresponding to each sample video into a plurality of sample data sets.

Specifically, when the sample historical playing information includes the time length of the sample video and the historical time length parameter, a first division manner may be adopted: and adding the historical playing information of the samples with the same time length of the contained sample videos to the same data set to obtain a plurality of sample data sets. Or when the sample historical playing information includes the time length of the sample video, the type of the historical playing end and the historical time length parameter, adopting a second division mode: and adding the historical playing information of the samples, which has the same historical playing end type and the same sample video duration, to the same data set to obtain a plurality of sample data sets.

Because the volume of the video content in the video platform is huge, in the step, when the data set is divided according to the time length, the data set can be divided by taking the second as the unit of the time length of the sample video. For example, taking a division manner one as an example, sample history playing information with a time length of 10 seconds of a contained sample video may be added to the data set 1, sample history playing information with a time length of 11 seconds of a contained sample video may be added to the data set 2 …, sample history playing information with a time length of 2700 seconds of a contained sample video may be added to the data set Z, and a plurality of sample data sets may be obtained. Taking the dividing mode two as an example, sample historical playing information that the time length seconds of the contained sample video is 10s and the type of the historical playing end is the PC end can be added into the data set 1 ', sample historical playing information that the time length seconds of the contained sample video is 11s and the type of the historical playing end is the PC end is added into the data set 2'.

When the data set is divided, the whole data volume is huge aiming at the historical playing information of the samples corresponding to all the sample videos, so that the division of the sample data set can be realized by adopting a bucket division algorithm so as to improve the efficiency of the division of the sample data set. The bucket dividing algorithm is to distribute data to different buckets according to the hash value of the data so as to complete the bucket dividing process of the data, wherein the buckets are sample data sets. The hash function used in the bucket dividing algorithm may be selected according to the data type.

Step 203, determining at least one preset time threshold function according to the historical time parameter included in the historical playing information of each sample in each sample data set.

Specifically, step 203 may include:

step 2031, determining each sample data set with the time length of the corresponding sample video greater than the first time length threshold as a first sample data set, and determining each sample data set with the time length of the corresponding sample video not greater than the first time length threshold as a second sample data set.

In this step, the first duration threshold may be set by a developer according to practical experience, and for example, the first duration threshold may be 10 s. Assuming that the time length of a sample video corresponding to the sample data set 1 to the sample data set 10 is not more than 10s, and assuming that the time length of a sample video corresponding to the sample data set 11 to the sample data set 3000 is more than 10s, the sample data set 11 to the sample data set may be determined as a first sample, and the sample data set 1 to the sample data set 10 of the data set 3000 may be determined as a second sample.

Step 2032, calculating a first quartile of the historical time duration parameter in each first sample data set, and taking the first quartile and the time duration of the sample video corresponding to the first sample data set as first sample points to obtain a plurality of first sample points.

In this step, when calculating the first quartile of the historical duration parameter in the first sample data set, the historical duration parameters in the historical playing information of each sample in the first sample data set may be arranged in an order from large to small, taking the historical duration parameter as the playing duration as an example, the playing durations in the historical playing information of each sample in the first sample data set may be arranged in an order from small to large to form a number series, and then the (n +1)/4 th number in the number series is determined as the first quartile of the historical duration parameter in the first sample data set. Further, assuming that the first quartile of the historical duration parameter in the first sample data set 23 is 10 and the duration of the sample video corresponding to the first sample data set 23 is 30s, (20, 23) may be determined as the first sample point corresponding to the first sample data set 23.

Step 2033, calculating a third quartile of the historical time length parameter in each second sample data set, and taking the third quartile and the time length of the sample video corresponding to the second sample data set as second sample points to obtain a plurality of second sample points.

In this step, when calculating the third quartile of the historical duration parameter in the second sample data set, the historical duration parameters in the historical play information of each sample in the second sample data set may be arranged in an order from large to small, taking the historical duration parameter as the play duration as an example, the play durations in the historical play information of each sample in the second sample data set may be arranged in an order from small to large to form a sequence, and then the 3(n +1)/4 number in the sequence is determined as the third quartile of the historical duration parameter in the second sample data set. Further, assuming that the third quartile of the historical duration parameter in the second sample data set 9 is 3, and the duration of the sample video corresponding to the second sample data set 9 is 9s, then (3, 9) may be determined as the third sample point corresponding to the second sample data set 23.

When the time length of the sample video is short, if the first quartile is continuously adopted as the sample point, it is easy to judge that the user is satisfied with the sample video by the false click of the user aiming at the sample video in the subsequent process, for example, for the video with the time length of 9s, the first quartile is only 3s, the false click of the user can easily reach the playing time length of 3s, and if the first quartile is taken as the standard, the false click can be easily determined as one satisfactory watching of the video. In the embodiment of the invention, the third quartile is taken as the sample point of the second sample data set, so that the problem of inaccurate judgment in the subsequent process can be avoided

Step 2034, constructing the at least one preset duration threshold function according to the plurality of first sample points and the plurality of second sample points.

Specifically, when the sample data set includes sample historical playing information with the same sample video duration, step 2034 may be implemented by the following sub-step (1):

substep (1): and performing linear fitting by using the plurality of first sample points and the plurality of second sample points to obtain a preset duration threshold function.

In this step, the duration of the sample video may be taken as a horizontal axis of a reference coordinate system, a first quartile or a third quartile of the historical duration parameter is taken as a vertical axis of the coordinate system, each first sample point and each second sample point are determined in the reference coordinate system, then each first sample point and each second sample point are sequentially connected to obtain a first curve, then the first curve is analyzed to obtain a preset duration threshold function, and in a specific implementation, the analysis may be performed by using MATLAB application, which is not limited in the embodiment of the present invention.

It should be noted that, in an actual application scenario, the number of videos with too long duration is small, and therefore, as the duration of the sample video increases, the first curve may have a large fluctuation, for example, fig. 2-2 is a schematic diagram of the first curve provided in the second embodiment of the present invention, as can be seen from fig. 2-2, a second half portion of the first curve has a significant fluctuation, and therefore, after obtaining the first curve, the portion with the large fluctuation in the first curve may be truncated, and only a portion with normal fluctuation is retained for analysis, for example, fig. 2-3 is another schematic diagram of the first curve provided in the second embodiment of the present invention, as can be seen from fig. 2-3, after truncating the portion of the first curve, the first curve becomes gentle.

When the sample data set includes sample historical playing information with the same sample video time length and the same historical playing end type, step 2034 may be implemented by the following substeps (2) to (3):

substep (2): and performing linear fitting by using the first sample point with the corresponding type of the historical playing end as the PC end and the second sample point with the corresponding type of the historical playing end as the PC end to obtain a first time parameter threshold function.

Since the behavior for the video is mainly generated at the mobile terminal and the PC terminal, and the other terminals are fewer and have small statistical significance, in the embodiment of the present invention, the types of the playing terminal may include the mobile terminal and the PC terminal, and of course, in another optional embodiment of the present invention, the types of the playing terminal may also include other terminals, such as a television terminal, and the like.

Further, the type of the historical playing end corresponding to the first sample data set corresponding to the first sample point is the type of the historical playing end corresponding to the first sample point, so that each first sample point calculated based on the first sample data set with the corresponding type of the historical playing end as the PC end and each second sample point calculated based on the second sample data set with the corresponding type of the historical playing end as the PC end can be determined in the reference coordinate system, and then the determined points are sequentially connected to obtain a second curve, and the second curve is analyzed to obtain a first preset duration parameter threshold function corresponding to the PC end.

Substep (3): and performing linear fitting by using the first sample point with the corresponding type of the history playing end as the mobile end and the second sample point with the corresponding type of the history playing end as the mobile end to obtain a second time length parameter threshold function.

In this step, each first sample point calculated based on the first sample data set with the corresponding type of the historical playing end as the moving end and each second sample point calculated based on the second sample data set with the corresponding type of the historical playing end as the moving end may be determined in the reference coordinate system, then the determined points are sequentially connected to obtain a third curve, and the third curve is analyzed to obtain a second preset duration parameter threshold function corresponding to the moving end.

Since the behavior characteristics of the user at the PC and the mobile terminal are obviously different, other operations may be performed at the PC, such as browsing a web page, and the duration parameter at the PC is generally greater than the duration parameter at the mobile terminal, for example, developers count, through statistics in advance, that the average values of the play duration and the click duration at the PC are 574.91s and 805.29s, respectively, 574.91, and the average values of the play duration and the click duration at the mobile terminal are 515.82s and 662.35s, respectively, so that it can be seen that the duration parameter at the PC is generally greater than the duration parameter at the mobile terminal. Therefore, in the embodiment of the invention, the accuracy of the preset duration parameter threshold function can be improved by determining the preset duration parameter threshold function corresponding to the different playing end types, so that the accuracy of determining the video satisfaction is improved.

It should be noted that, in the process of using the terminal, the user may browse other web pages while playing the video, which may result in poor representation of the click duration for the actual desire of the user for the video, and therefore, preferably, the play duration is used as the history duration parameter, so as to more accurately determine whether the target user is satisfied with the target video. It should be noted that, in an actual application scenario, since each video platform may be independent from each other, that is, a developer of the video platform a may not be able to obtain all background data of the video platform B, and the difficulty of obtaining the playing time of videos in other video platforms is high, in actual application, the developer may use the playing time of the video in the video platform as a historical time parameter, and use the click time of videos in other video platforms as a historical time parameter. Further, when the preset duration parameter threshold function is determined, a first preset duration parameter threshold function corresponding to the PC end can be determined in advance based on the playing duration, a first preset duration parameter threshold function corresponding to the PC end is determined based on the clicking duration, a second preset duration parameter threshold function corresponding to the mobile end is determined based on the playing duration, a second preset duration parameter threshold function corresponding to the mobile end is determined based on the clicking duration, four groups of preset duration parameter threshold functions are obtained, and the satisfaction degree of a user on videos in the platform and videos in other platforms can be conveniently and simultaneously determined.

And 204, acquiring a time length parameter of the target user for playing the target video.

Specifically, the implementation manner of this step may refer to step 101 described above, and details of the embodiment of the present invention are not described herein.

Step 205, determining a duration parameter threshold corresponding to the target video according to the attribute parameters of the target video and at least one preset duration parameter threshold function.

Specifically, when the sample data set includes sample historical playing information with the same sample video duration, that is, when a preset duration parameter threshold function is predetermined through the foregoing steps 201 to 203, the attribute parameter may include the duration of the target video, and accordingly, the step 205 may be implemented through the following step 2051:

and step 2051, if the duration of the target video is within the argument range of the preset duration parameter threshold function, substituting the duration of the target video as an argument into the preset duration parameter threshold function to obtain a duration parameter threshold corresponding to the target video.

For example, assuming that the time length of the target video is 2000s, and the argument range of the preset time length parameter threshold function is [1, 2500], 2000s may be substituted into the preset time length parameter threshold function to obtain the time length parameter threshold corresponding to the target video.

When the sample data set includes sample historical play information with the same sample video duration and the same historical play end type, that is, when a first preset duration parameter threshold function corresponding to the PC end and a second preset duration parameter threshold function corresponding to the mobile end are predetermined through the above steps 201 to 203, the attribute parameter may include the duration of the target video and the play end type corresponding to the target video in the play operation of this time, and accordingly, the step 205 may be implemented through the following steps:

and step 2052, determining a playing end type corresponding to the target video in the playing operation to obtain a target playing end type.

In this step, a log corresponding to the play operation may be obtained from background data of the video platform, and a play end type corresponding to the target video in the play operation is determined by extracting a key field in the log, so as to obtain the target play end type.

And step 2053, determining a preset duration parameter threshold function corresponding to the type of the target playing end as a target function.

For example, assuming that the type of the target player is a PC end, a first time parameter threshold function corresponding to the PC end may be determined as the target function.

And step 2054, if the duration of the target video is within the argument range of the target function, substituting the duration of the target video as an argument into the target function to obtain a duration parameter threshold corresponding to the target video.

It should be noted that, when the duration of the target video is not within the argument range of the preset duration parameter threshold function, the maximum value of the dependent variable of the preset duration parameter threshold function, that is, the maximum duration parameter threshold, may be determined as the duration parameter threshold corresponding to the target video.

And step 206, determining whether the target user is satisfied with the target video according to the time length parameter threshold and the time length parameter.

Specifically, the implementation manner of this step may refer to step 103, which is not described herein again in this embodiment of the present invention.

In another optional embodiment of the present invention, after determining the satisfaction degree of the user based on the preset duration parameter threshold function, a manual evaluation mode may be further adopted, and with the partial videos as evaluation objects, the determination effects of the videos in the mode of determining the satisfaction degree of the user based on the preset duration parameter threshold function and the mode of determining the satisfaction degree of the user based on the conventional fixed duration threshold are counted, so as to further improve the method in the present invention. Specifically, the percentage of unsatisfied clicks in all clicks can be counted in a mode of determining the satisfaction degree of the user based on a preset duration parameter threshold function and a mode of determining the satisfaction degree of the user based on a traditional fixed duration threshold, then, based on videos with the percentage difference larger than 0.2 corresponding to the two modes and search keywords corresponding to the videos, whether the quality of the videos meets the corresponding search keywords or not is judged manually, if yes, a determination mode with a low percentage is determined to win, if not, a determination mode with a high percentage is determined to win, and through specific experiments, the success rate of the method for determining the satisfaction degree of the user based on the preset duration parameter threshold function provided by the embodiment of the invention can be obtained to be about 92%.

To sum up, in the video satisfaction determining method provided by the second embodiment of the present invention, the sample historical play information corresponding to each sample video is determined according to the sample log corresponding to each sample video, then the sample historical play information corresponding to each sample video is divided into a plurality of sample data sets based on the time length of each sample video, at least one preset time length threshold function is determined based on the data sets, then the time length parameter of the play operation of the target user on the target video is obtained, then the time length parameter threshold corresponding to the target video is determined according to the attribute parameter of the target video and the at least one preset time length parameter threshold function, and finally, whether the target user is satisfied with the target video is determined according to the time length parameter threshold and the time length parameter, compared with the manner that the same fixed time length threshold is adopted as the judgment basis for all videos in the prior art, in the embodiment of the invention, the time length parameter threshold corresponding to the target video is determined according to the attribute parameters of the target video, so that the judgment basis of different target videos is ensured to be determined according to the attributes of the different target videos, and the accuracy of determining the video satisfaction is further improved.
