Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
Fig. 1 is a kind of barrage screening technique disclosed in the embodiment of the present application, comprising the following steps:
S101: barrage is pre-processed, and removal is unsatisfactory for the barrage of preset condition.
Preset condition includes that non-advertisement barrage and/or smoothness degree are greater than threshold value.Wherein, clear and coherent degree refers to the clear and coherent journey of sentence
Degree, in general, the clear and coherent degree of Chinese can be expressed as following values according to the clear and coherent degree of sentence: 1,2,3,4,5,1 indicates very not
Smoothness, 5 indicate very clear and coherent, and smoothness degree gradually increases from 1 to 5.
Based on above-mentioned preset condition, specifically, pretreatment includes that purposes of commercial detection and smoothness degree detect, wherein purposes of commercial detection
Purpose be, detect advertisement barrage.The purpose of clear and coherent degree detection is, determines the clear and coherent degree of barrage.The detection of clear and coherent degree,
The numerical value for the clear and coherent degree that can be provided according to user for sample, training pattern, so that the model after training has automatic evaluation
The function of clear and coherent degree.Threshold value can be empirically arranged, for example, threshold value is 3.
Pretreated purpose is that removal advertisement barrage is not more than the barrage of threshold value with smoothness degree.The threshold value of clear and coherent degree can be with
It presets.
In other words, S101 is equivalent to the anti-spam processing of barrage.Therefore, existing anti-spam service remote can be called
Invocation of procedure agreement (Remote Procedure Call Protocol, RPC) interface carries out detection and the bullet of advertisement barrage
The detection of curtain smoothness degree.After obtaining testing result, removal advertisement barrage is not more than the barrage of threshold value with smoothness degree.
It should be noted that S101 is optional step.The detection of specific advertisement barrage and the detection of barrage smoothness degree
Algorithm (setting principle of the threshold value including clear and coherent degree), may refer to the prior art, which is not described herein again.
S102: the feature of pretreated barrage is extracted.
In the present embodiment, 9 features are proposed, it is therefore intended that more comprehensively evaluate the quality of barrage.Assuming that for extracting
The barrage of feature is the N barrage extracted from one section of video at interval of 5 minutes, then the feature for the barrage for needing to extract includes:
1, role's barrage degree:
Wherein, for any one barrage in N barrage, if it is role's barrage, then molecule takes the first numerical value,
Such as 1, otherwise, molecule takes second value, such as 0, and denominator is the total quantity of role's barrage in N barrage.
In the present embodiment, role's barrage refers to, is directed to the barrage of the certain role input in video.Specifically, user
In the playing process of video, some personage's (or other targets) occurred in video can be clicked, for the personage of click
Then the barrage is delivered for the particular persons (or other targets) in video to (perhaps other targets) input barrage, therefore,
Belong to role's barrage.
As it can be seen that compared to common barrage, deliver role's barrage, user and video website need stronger level of interaction,
That is role's barrage is larger to the contribution of user's level of interaction.
2, degree is thumbed up:
Wherein, for any one barrage in N barrage, molecule thumbs up number for what this barrage obtained, point
Mother is in N barrage, what every barrage obtained thumbs up the sum of number.
For example, the number that thumbs up that number is the acquisition of the 1, the 2nd article of barrage that thumbs up that the 1st article of barrage obtains is the 2, the 3rd article of barrage
The number that thumbs up obtained is 2, then the 1st article of barrage thumbs up degree
Therefore the interaction that barrage needs user and video website is thumbed up, so, degree is thumbed up for reflecting the user of barrage
Level of interaction, thumbing up for barrage acquisition is several more, and the interaction times for illustrating that user is done based on barrage are more, and barrage hands over user
The contribution of mutual degree is bigger.
Role's barrage degree and the degree that thumbs up can be divided into user's interaction category feature.In the present embodiment, user's interaction
Category feature can only include role's barrage degree, and the degree that thumbs up is optional feature.Certainly, role's barrage degree and to thumb up degree equal
It extracts, it is more comprehensive for evaluation of the barrage for the contribution of user's level of interaction.
3, positive viewpoint word content:
Wherein, for any one barrage in N barrage, the positive viewpoint word quantity in denominator is this barrage
In include positive viewpoint word quantity, negative sense viewpoint word quantity be this barrage in include negative sense viewpoint word quantity.
It should be noted that positive viewpoint word and negative sense viewpoint word can be preset, that is, preset positive viewpoint word
Set and negative sense viewpoint set of words belong to the word of positive viewpoint set of words for positive viewpoint word, belong to negative sense viewpoint set of words
Word is to belong to negative sense viewpoint word.Specifically, during determining the positive viewpoint word content of certain barrage, first by this barrage
In word respectively compared with the word in positive viewpoint set of words and negative sense viewpoint set of words, if a word and positive viewpoint word set
A word in conjunction is identical, then the word is positive viewpoint word, if a word is identical as a word in negative sense viewpoint set of words,
Then the word is negative sense viewpoint word.
Positive viewpoint word degree reflects the positive emotion degree of barrage, and positive viewpoint word degree value is bigger, illustrates barrage
The positive emotion degree of reflection is bigger.
4, text size accounting:
Wherein, for any one barrage in N barrage, molecule is for the character for including in this barrage
Number, denominator are the sum of the number of character for including in N barrage in every barrage.
For example, the number that the number for the character for including in the 1st article of barrage is the character for including in the 10, the 2nd article of barrage is 20,
The number for the character for including in 3rd article of barrage is 20, then the text size accounting of the 1st article of barrage is
5, Chinese character accounting:
Wherein, for any one barrage in N barrage, molecule is the Chinese character for including in this barrage
Number, a Chinese character are considered as a Chinese character.Denominator is the sum of the number for all characters for including, institute in this barrage
Having character includes: Chinese character and outer Chinese character etc..The type of character can be preset.
6, noun accounting:
Wherein, for any one barrage in N barrage, molecule is for the noun for including in this barrage
Number, denominator are the sum of the number for all participles for including in this barrage, and participle includes noun, verb and adjective.
Specifically, word segmentation processing first can be carried out to this barrage, word segmentation result is obtained, word segmentation result includes forming this
All participles of barrage.Word segmentation processing algorithm may refer to the prior art, and which is not described herein again.
7, verb accounting:
Compared with noun accounting, molecule is the number of verb, and which is not described herein again.
Above-mentioned text size accounting, Chinese character accounting, noun accounting, verb accounting can be used as the semantic content of barrage
Feature, for characterizing the specific gravity of effective content in barrage.Above-mentioned semanteme content characteristics can choose at least one, the semanteme of selection
Content characteristics are more, then more comprehensive for the evaluation of the specific gravity of effective content.
8, freshness:
Wherein, for any one barrage in N barrage, molecule delivered day apart from the same day for this barrage
Number of days, denominator deliver number of days the sum of of the day apart from the same day for every barrage in N barrage.
For example, the 1st article is delivered for barrage 2018-3-1 days by user, the 2nd article is delivered for barrage 2018-3-4 days by user, and is counted
The same day for calculating freshness is 2018-3-4, then the freshness of the 1st article of barrage
As can be seen that expired time is longer, then freshness is lower.
It should be noted that calculated by taking number of days as an example in the calculation formula of the above freshness, other than number of days,
Barrage such as delivers the moment, delivers the moon at the other times unit, can substitute number of days, as the chronomere for calculating freshness.Generally
For including, freshness is used to characterize the duration for delivering time gap current time of barrage.
9, the excellent degree of plot:
The excellent degree of the plot are as follows: the ratio of the barrage amount in i-th second barrage amount and preset time range is preset
Time range includes described i-th second.The excellent degree of plot is used to indicate the density of barrage, and the density of barrage is bigger, illustrates play
The barrage that feelings receive when playing is more, then it represents that the plot of barrage evaluation is more excellent.Time range, which is here preset at, with 300 seconds is
Example, but be not limited to 300 seconds.
In conclusion for one aspect, user's interaction category feature for extracting barrage in above-mentioned 9 features respectively, just
It is more comprehensive to emotion degree, semantic content characteristics and freshness and excellent degree feature, the evaluation angle of feature.
For another party, in above-mentioned 9 features, feature 3,5,6 and 7 is based on a barrage and extracts, and is considered as absolutely
To feature, feature 1,2,4 and 8,9 be barrage (or a unit time barrage) and a plurality of barrage comparison result, can be with
Regard relative characteristic as.Either absolute feature or relative characteristic can reflect the quality of barrage.It include absolute in feature
Feature includes relative characteristic again, can more fully reflect the quality of barrage.
S103: using the feature of the barrage extracted, the mass fraction of barrage is calculated.
In the present embodiment, classical Rogers's base of a fruit function is deformed to obtain such as minor function:
The domain of deformed function is (0 ,+∞), and codomain is (0,1).
Wherein, the weighted sum of all features is to be added again after the feature of the barrage of said extracted and respective multiplied by weight
Obtained result.
The weight of different characteristic can be preset, and the weight of a feature is bigger, illustrate the contribution for mass fraction
It is bigger.
S104: barrage is screened.
The foundation of screening can be the mass fraction of barrage.Specifically, can according to barrage mass fraction to barrage into
Row sequence, by the preceding preset quantity barrage of ranking results, as the selection result.Alternatively, mass fraction is greater than preset threshold
Barrage, as the selection result.
Alternatively, in addition to the mass fraction of barrage, the foundation of screening can also include: barrage length, Chinese character accounting and
Multiplicity.Specifically, after being ranked up according to mass fraction, then delete barrage length from ranking results and be unsatisfactory for preset length
Barrage and Chinese character accounting be unsatisfactory for the barrage of preset accounting.
Wherein, barrage length refers to the quantity of the significant character in barrage, and significant character is the intention that can express user
Character, significant character can be preset, for example, using at least five Chinese character as the standard of barrage length, even if this barrage
The enough height of mass fraction, or sequence is enough forward, also to be deleted, cannot function as the barrage being selected.
The foregoing feature 7 of Chinese character accounting, here as individual screening foundation.
Further, after being screened according to barrage length, Chinese character accounting and mass fraction, weight can also be used
Multiplicity is screened.
Multiplicity refers to, the similarity degree with other barrages, and cosine phase can be used in the similarity degree between two barrages
It is calculated like degree, reference can be made to the prior art, which is not described herein again.
If the similarity of two barrages so far is greater than preset similarity threshold, to deleting a wherein barrage.Into
One step, deleting foundation can be any one in mass fraction, barrage length and Chinese character accounting.For example, deleting matter
Measure the lower barrage of score.
It can be seen that the feature for extracting barrage, and the quality of the feature calculation barrage according to extraction from process shown in FIG. 1
Score, then be ranked up according to mass fraction, barrage is finally filtered out from sequence.With the side of existing random selection barrage
Formula has higher readability, that is, has higher quality according to the barrage that process shown in FIG. 1 filters out.
In order to further increase for the screening effect of barrage, it can be based on process shown in FIG. 1, for already present bullet
Curtain (the hereinafter referred to as storage barrage) process flow different with the barrage newly increased (hereinafter referred to as newly-increased barrage) progress.
Fig. 2 is another barrage screening technique disclosed in the embodiment of the present application, comprising the following steps:
S201: with the preset period, storage barrage is pre-processed, feature extraction, calculates mass fraction, and according to matter
Amount score is ranked up, and obtains the first ranking results.
Wherein, pretreatment, feature extraction and the concrete mode for calculating mass fraction, may refer to step shown in FIG. 1,
Which is not described herein again.
In the present embodiment, the preset period can be arranged as unit of the moon, for example, one month or two months etc..
S202: in the case where receiving newly-increased barrage, the execution of newly-increased barrage is pre-processed, feature extraction, calculating
Mass fraction, and be ranked up according to mass fraction, obtain the second ranking results.
Newly-increased barrage is inputted by user.
S203: by the first ranking results and the second ranking results barrage according to based on feature obtain mass fraction into
Row sequence, obtains third ranking results.
That is, after the first ranking results are mixed with the barrage in the second ranking results, then sort, sequence
According to the mass fraction for being barrage.
S204: according to barrage length, Chinese character accounting and multiplicity, barrage is screened from third ranking results.
Specifically, from third ranking results or in third ranking results before sequence in preset quantity barrage, selection
Barrage length is greater than preset length out and Chinese character accounting is greater than the barrage of preset ratio, and removes weight in the barrage selected
Multiplicity is greater than the lower barrage of mass fraction in the barrage of preset threshold, thus the barrage filtered out.
For example, being the period with one month, storage barrage is ranked up, obtain and stores the first sequence as a result, right in real time
Newly-increased barrage is ranked up, and obtains the second ranking results.After obtaining the second ranking results, stored first sequence knot is obtained
Barrage in first ranking results and the second ranking results is mixed and is ranked up, obtains third ranking results, then to third by fruit
Ranking results are screened.
During shown in Fig. 2, the sequence of different frequency is carried out for storage barrage and newly-increased barrage, is realizing newly-increased bullet
In the case where the real-time screening of curtain, it can also guarantee the screening for storage barrage, and storage barrage and newly-increased barrage is common
