Determine the accuracy of video satisfaction.
Embodiment two
Fig. 2-1 is the step flow chart that a kind of video satisfaction provided by Embodiment 2 of the present invention determines method, such as Fig. 2-1
Shown, this method may include：
Step 201, according to the corresponding sample daily record of each Sample video, determine the corresponding sample history of each Sample video
Broadcast information.
Specifically, step 201 may include：
Step 2011, according to the corresponding sample daily record of each Sample video, determine each Sample video corresponding at least one
History broadcast information.
In this step, history broadcast information can include at least the duration and history duration parameters of Sample video, this is gone through
History duration parameters may include that history playing duration or history click duration.Further, it can also be wrapped in history broadcast information
Other content is included, for example, the history including Sample video plays end type, the corresponding every history of each Sample video plays letter
Breath indicates that the primary record that the Sample video is played by user, history broadcast information can embody Sample video in this time broadcasting
Specifically which type click duration that end plays and specific or playing duration are played in.
Specifically, in the corresponding at least one history broadcast information of each Sample video of determination, it can be first flat from video
The backstage of platform obtains the corresponding daily record of the Sample video, obtains the corresponding sample daily record of the video, the Sample video corresponding day
All daily records that will, which can be the Sample video, to have added up since enter video platform can also be the Sample video at some
Between the daily record that adds up in section, the embodiment of the present invention is not construed as limiting this.It is then possible to suitable according to the time that sample daily record generates
Sequence one by one analyzes every sample daily record, generally, the daily record that user can generate for each behavior of video, daily record
It would generally include clicking time point, be clicked the ID of video, be clicked the corresponding broadcasting end type of video and this is clicked and regards
The duration of frequency, in this step, can according in every sample daily record click time point, be clicked video ID, be clicked and regard
Frequently corresponding broadcasting end type, determines the concrete behavior of the corresponding user of this daily record.It is exemplary, include with history broadcast information
The history broadcasting end type of Sample video, the duration and history duration parameters of Sample video, and history duration parameters are to play
For duration, it is assumed that indicate Sample video a in 15 purpose January in 2018 in the corresponding first sample daily record 1 of Sample video a
20：00 is opened in mobile terminal, and expression Sample video a is in January, 2018 in the corresponding Article 2 sample daily records 2 of Sample video a
The 20 of 15 mesh：02 is closed in mobile terminal, then the corresponding history broadcast information A of Sample video a can be generated, it is assumed that sample regards
The ID of frequency a be 001, when it is 40 minutes a length of, history broadcast information A can be expressed as：
Platform_id (mobile terminal) t doc_id (001) t duration (40min) t playtime (2min)；
Wherein, platform_id indicates that broadcasting end type of the Sample video in this time broadcasting, doc_id indicate that sample regards
The ID of frequency, duration indicate that the duration of Sample video, playtime indicate playing duration of the Sample video in this time broadcasting.
Step 2012 obtains the corresponding at most m history broadcast information of each Sample video, obtains each Sample video pair
The sample history broadcast information answered.
In this step, m is the maximum item number of the pre-defined corresponding sample history broadcast information of each Sample video.Its
In, the concrete numerical value of m can be that developer sets according to practical experience, since some Sample videos have a large amount of click
Behavior, and then corresponding a large amount of sample daily record is had, in this way, the Sample video less compared to the behavior of click, these possess
Proportion occupied by the history broadcast information of a large amount of Sample videos for clicking behavior can be larger, causes data distribution unbalanced, into
And the preset duration function determined according to data can be caused inaccurate, in the embodiment of the present invention, by limiting each Sample video
The maximum item number of corresponding history broadcast information, can improve the harmony of data, so improve finally determine it is default when
The accuracy of long function.
Specifically when obtaining, if the item number of the corresponding all history broadcast informations of the Sample video is not more than m, obtain
The corresponding all history broadcast informations of the Sample video, obtain the corresponding sample history broadcast information of the Sample video, if should
The item number of the corresponding all history broadcast informations of Sample video is more than m, then plays letter from the corresponding all history of the Sample video
M history broadcast information is randomly choosed in breath, as the corresponding sample history broadcast information of the Sample video.It is, of course, also possible to
Other acquisition modes, the embodiment of the present invention are taken to be not construed as limiting this, as long as ensureing that the item number chosen is not more than m.
Step 202, the duration based on each Sample video draw the corresponding sample history broadcast information of each Sample video
Divide to multiple sample data sets.
Specifically, can include the duration and history duration parameters of Sample video in the sample history broadcast information
When, using dividing mode one：By comprising the identical sample history broadcast information of duration of Sample video be added to same data
Collection, obtains multiple sample data sets.Can also include the duration of Sample video, history broadcasting in the sample history broadcast information
When holding type and history duration parameters, using dividing mode two：By comprising history play that end type is identical and Sample video
The identical sample history broadcast information of duration be added to same data set, obtain multiple sample data sets.
Since the volume of video content in video platform is more huge, in this step, data set is divided according to duration
When, it can be divided using the second as the unit of the duration of Sample video.It is exemplary, it, can be with by using for dividing mode one
By comprising Sample video duration number of seconds be 10s sample history broadcast information be added in data set 1, by comprising sample
The duration number of seconds of video be 11s sample history broadcast information be added in data set 2 ... by comprising Sample video duration
Number of seconds is that the sample history broadcast information of 2700s is added in data set Z, obtains multiple sample data sets.To use division side
For formula two, can by comprising Sample video duration number of seconds be 10s and history play end type be the ends PC sample history
Broadcast information is added in data set 1 ', by comprising Sample video duration number of seconds be 11s and history play end type be PC
The sample history broadcast information at end is added in data set 2 ' ... by comprising the duration number of seconds of Sample video be 2700s and to go through
History plays the sample history broadcast information that end type is the ends PC and is added in data set Z ', obtains multiple sample data sets.
Due to when dividing data set, being to be directed to the corresponding sample history broadcast information of all Sample videos, overall data
Amount is more huge, therefore can take point bucket algorithm to realize the division of sample data set, to improve sample data set division
Efficiency.Point bucket algorithm is referred to according to the cryptographic Hash of data by data distribution to each different bucket, to complete data
Divide bucket process, bucket is sample data set.Wherein, the hash function divided employed in bucket algorithm can be selected according to data type
It selects.
Step 203, the history duration parameters for being concentrated every sample history broadcast information to include according to each sample data, really
Fixed at least one preset duration threshold function table.
Specifically, step 203 may include：
Step 2031, the sample data set that the duration of each corresponding Sample video is more than to the first duration threshold value, determine
For first sample data set, the duration of each corresponding Sample video is not more than to the sample data set of the first duration threshold value, really
It is set to the second sample data set.
In this step, which can be that developer sets according to practical experience, and exemplary, this first
Duration threshold value can be 10s.Assuming that 1~sample data set of sample data set, 10 corresponding Sample video duration is not more than 10s, it is false
If 11~sample data set of sample data set, 3000 corresponding Sample video duration is more than 10s, then can be by sample data set

Problem
Step 2034, according to the multiple first sample point and the multiple second sample point, at least one described in structure
A preset duration threshold function table.
Specifically, when sample data concentration includes the identical sample history broadcast information of Sample video duration, step
2034 can be realized by following sub-steps (1)：
Sub-step (1)：Linear fit is carried out using the multiple first sample point and the multiple second sample point, is obtained
To preset duration threshold function table.
In this step, can first with Sample video when a length of reference frame horizontal axis, with the of history duration parameters
One or four scores or third quartile are the longitudinal axis of coordinate system, determined in the reference frame each first sample point and
Then each first sample point and the second sample point are sequentially connected, the first curve are obtained, then to this by each second sample point
First curve is parsed, and preset duration threshold function table is obtained, and in specific implementation, MATLAB applications may be used and solved
Analysis, the embodiment of the present invention are not construed as limiting this.
It should be noted that due in practical application scene, the negligible amounts of the long video of duration, therefore with sample
The growth of video length, the first curve is exemplary it is possible that larger fluctuation, Fig. 2-2 be second embodiment of the present invention provides
The first curve synoptic diagram of one kind, from Fig. 2-2 as can be seen that the first curve second half section part by significantly fluctuating, therefore,
It after obtaining the first curve, can be blocked larger part is fluctuated in first curve, only retain the part of normal fluctuation
It is parsed, exemplary, Fig. 2-3 is another first curve synoptic diagram provided by Embodiment 2 of the present invention, from can be in Fig. 2-3
Find out, after the part for blocking the first curve, the first curve becomes flat.
When sample data concentration includes that Sample video duration is identical and history plays the identical sample history of end type and plays
When information, step 2034 can be realized by following sub-steps (2)~sub-step (3)：
Sub-step (2)：The first sample point and the broadcasting of corresponding history that end type is the ends PC are played using corresponding history
It holds the second sample point that type is the ends PC to carry out linear fit, obtains the first duration parameters threshold function table.
Due to occurring mainly with mobile terminal and the ends PC for the behavior of video, other termination it is less, statistical significance is little, because
This, in the embodiment of the present invention, it may include mobile terminal and the ends PC to play end type, certainly, in another optional implementation of the present invention
In example, it can also includes other termination to play end type, for example, television, etc..
Further, the corresponding history of the corresponding first sample data set of first sample point plays end type, as this
The corresponding history of one sample point plays end type, therefore, can be determined in reference frame each based on corresponding history
The first sample point that the first sample data set that end type is the ends PC is calculated is played, and end is played based on corresponding history
Type is the second sample point that second sample data set at the ends PC is calculated, and then connects each point determined successively
It connects, obtains the second curve, then second curve is parsed, obtain the first preset duration parameter threshold corresponding with the ends PC
Function.
Sub-step (3)：End type is played using corresponding history to broadcast for the first sample point of mobile terminal and corresponding history
It puts the second sample point that end type is mobile terminal and carries out linear fit, obtain the second duration parameters threshold function table.
In this step, it can determine that each corresponding history broadcasting end type that is based on is mobile terminal in reference frame
The first sample point that is calculated of first sample data set, and play that end type is mobile terminal based on corresponding history the
Then each point determined is sequentially connected, obtains third curve by the second sample point that two sample data sets are calculated,
Then the third curve is parsed, obtains the second preset duration parameter threshold function corresponding with mobile terminal.
Behavioral trait due to user at the ends PC and mobile terminal has apparent difference, it may be carried out at the same time at the ends PC
He operates, for example browses webpage, and then the duration parameters at the ends PC can be caused generally to be more than the duration parameters in mobile terminal, example
, for developer by counting in advance, it is respectively 574.91s to count the playing duration at the ends PC and click the average value of duration
And 805.29s, and 574.91, the playing duration of mobile terminal and the average value for clicking duration be respectively 515.82s and
662.35s, it can be seen that the duration parameters at the ends PC are generally more than the duration parameters in mobile terminal.Therefore, in the embodiment of the present invention,
When determining that preset duration parameter threshold function corresponding with end type is played can improve default for different broadcasting end types
The accuracy of long parameter threshold function, and then improve the accuracy for determining video satisfaction.
It should be noted that since user is during using terminal, may be browsed while the video of broadcasting
Other webpages click duration for the representative poor of the practical wish to video of user in this way, may result in, it is therefore preferable that
, using playing duration as history duration parameters, more accurately it can determine whether target user is satisfied with target video.It needs
To be illustrated, in actual application scenarios, since each video platform may be independent from each other, that is, be exactly, video platform A
All back-end datas of video platform B that possibly can not get of developer, obtain the video in other video platforms
The difficulty of playing duration is larger, therefore, in practical application, when developer can use broadcasting to the video in this video platform
It is long to be used as history duration parameters, for the video in other video platforms using click duration as history duration parameters.Into one
Step ground, when determining preset duration parameter threshold function, can be in advance based on playing duration and determine corresponding with the ends PC first
Preset duration parameter threshold function, then determine the first preset duration parameter threshold letter corresponding with the ends PC based on duration is clicked
Number determines the second preset duration parameter threshold function corresponding with mobile terminal based on playing duration, then true based on duration is clicked
The second preset duration parameter threshold function corresponding with mobile terminal is made, and then obtains four groups of preset duration parameter threshold functions,
And then convenient while determining user is to the satisfaction of the video in the video and other platforms in this platform.
Step 204 obtains duration parameters of the target user to the play operation of target video.

Function.
It is exemplary, it is assumed that it is the ends PC that target, which plays end type, can will the first duration parameters threshold corresponding with the ends PC
Value function is determined as object function.
If the duration of step 2054, the target video, will be described in the independent variable value range of the object function
The duration of target video is substituted into as independent variable in the object function, obtains the corresponding duration parameters threshold of the target video
Value.
It should be noted that when the duration of target video is not in preset duration parameter threshold argument of function value range
Can be exactly that maximum time parameter threshold is determined as by the dependent variable maximum value of the preset duration parameter threshold function when interior
