Include the description information of the UGC videos after being clustered in video recommendations list in the embodiment of the present invention,
Therefore these description informations are more comprehensive, solve the problem of lacking some collection numbers；And these description informations are arranged
Sequence, therefore solve the problem of order is chaotic.
Below, a kind of creation method of video index table and a kind of recommendation side of video are specifically described by embodiment two
Method.
Embodiment two：
Reference picture 3, shows a kind of flow chart of the creation method of video index table of the embodiment of the present invention two, this method
Specifically it may comprise steps of：
Step 301, multiple UGC videos of client upload and the video ID of each UGC video are obtained.
During user is uploaded onto the server UGC videos by client, server can be protected to these UGC videos
Deposit, wherein, each UGC videos are to that should have a video ID.First, server can obtain UGC videos that it is preserved and
The video ID of each UGC video, then carries out relevant treatment to it, to generate corresponding video index table.
Step 302, the video metadata of each UGC video is extracted respectively.
After above-mentioned multiple UGC videos are got, the video metadata of each UGC video is extracted respectively, then according to this
A little video metadatas can be clustered to the multiple UGC videos.
Step 303, the multiple UGC videos are clustered, and for each cluster distribution Video clustering ID.
In the embodiment of the present invention, the video metadata can include video title, video duration, video uploader, regard
The information such as frequency type, can be clustered according to these video metadatas to the multiple UGC videos, so as to will belong to same class
Other UGC videos flock together.If for example, UGC videos be TV play class UGC videos, can be by same portion's TV
Acute each collection flocks together；If UGC videos are the UGC videos of variety show class, can be by same variety show
Each phase program aggregation is together, etc..
Due to for some UGC videos, only by its video title, video duration, video uploader, video type these
Information can not be clustered exactly.For example, for the UGC videos of TV play class, the TV play of same title is potentially included
Multiple versions, such as this TV play of entitled " Hero Shooting Vulture ", its potentially include 83 editions, 94 editions, 03 edition, 08
Multiple versions such as version, if only can not be by " Hero Shooting Vulture " TV play of same version by information such as above-mentioned video titles
Each collection flocks together exactly.Therefore, in the embodiment of the present invention, the video metadata can also include video director, regard
The information such as frequency performer, video director, the video performer of the TV play of different editions are different, therefore according to these video informations
Can a certain version of unique mark TV play, so as to improve the accuracy of Video clustering.
In one preferred embodiment of the invention, the step 303 can specifically include following sub-step：
Sub-step a1, carries out Similarity Measure to the video metadata of each two UGC videos respectively；
Sub-step a2, the corresponding UGC videos of video metadata similarity being located within default similarity interval are true
It is set to and belongs to same cluster.
Similarity Measure is carried out to the video metadata of each two UGC videos respectively, if similarity is located at default phase
Like spending within interval, then it can illustrate that corresponding two UGC videos belong to same cluster.Set for the similarity is interval
Put, it is ensured that the similarity for belonging to the video metadata of the UGC videos of same cluster can neither be too small, can not be too big, such as
Fruit is too big, then illustrates that the relevant information difference of two UGC videos is very big, be not belonging to same classification, if too small, illustrate two
The relevant information difference very little of individual UGC videos, it may belong to identical UGC videos.Those skilled in the art can be according to reality
Border experience sets the interval corresponding numerical value of similarity, and the embodiment of the present invention is not any limitation as to specific numerical value.
In one preferred embodiment of the invention, in the similarity position for judging the video metadata of two UGC videos
Outside default similarity is interval, and when being less than the smaller boundary value in the interval, for example similarity interval is [a, b], when
When judging that similarity is less than boundary value a, because the two UGC videos may be considered identical UGC videos in the case of this kind,
Therefore one belonged in identical UGC videos can also be further deleted, so as to avoid video from repeating, takes video resource
Problem.
In the embodiment of the present invention, above-mentioned sub-step a1 can include following sub-step：
Sub-step a11, a corresponding vector is converted into by the metadata of each UGC videos；
Sub-step a12, carries out similarity meter according to corresponding vector to the video metadata of each two UGC videos respectively
Calculate.
In the embodiment of the present invention, sub-step a12 can be by calculating two vectorial Euclidean distances, manhatton distance, folders
The methods such as angle cosine value carry out Similarity Measure to the video metadata of each two UGC videos.For example, can calculate each two to
Euclidean distance between amount, when the Euclidean distance is located within the default first distance interval, determines that two vectors are right
The similarity for the video metadata answered is located within default similarity interval；The Man Ha between each two vector can also be calculated
Distance, when the manhatton distance is located within default second distance interval, determines the corresponding video of two vectors
The similarity of metadata is located within default similarity interval；The cosine value of the angle of each two vector can also be calculated, when
When the cosine value of the angle is located within default cosine value interval, the phase of the corresponding video metadata of two vectors is determined
It is located at like degree within default similarity interval.It is interval and cosine value interval for the wherein first distance interval, second distance
Concrete numerical value, is utilized technical staff and carries out related setting according to practical experience, the embodiment of the present invention is to specific numerical value
It is not any limitation as.
Euclidean distance is a kind of distance calculating method for being easiest to understand, the distance from point-to-point transmission in Euclidean space is public
Formula.Two n-dimensional vector a (x11, x12..., x1n) and b (x21, x22..., x2n) between Euclidean distance be：The form for being expressed as vector operation can also be used：
Manhatton distance is also referred to as city block distance.Two n-dimensional vector a (x11, x12..., x1n) and b (x21, x22...,
x2n) between manhatton distance be：
Included angle cosine can be used to weigh the difference of two vector directions in geometry, and this concept is borrowed in machine learning to weigh
Difference between sample vector.For two n-dimensional vector a (x11, x12..., x1n) and b (x21, x22..., x2n), it can use similar
The similarity degree between them is weighed in the concept of included angle cosine：I.e.
Included angle cosine span is [- 1,1].Included angle cosine is bigger to represent that two vectorial angles are smaller, and included angle cosine is smaller to be represented
The angle of two vectors is bigger, and when two vectorial directions are overlapped, included angle cosine takes maximum 1, when two vectorial directions are complete
Opposing angles cosine takes minimum value -1.
By said process, it can will belong to same category of UGC videos and flock together, therefore can be given birth to after processing
Into multiple clusters, a Video clustering ID then can be distributed for each cluster, with one cluster of unique mark.
Step 304, video duration is obtained respectively for the UGC videos in each described cluster, when regarding for some UGC video
When frequency duration is located at outside default duration interval, the UGC videos are deleted from the cluster belonging to it.
In one preferred embodiment of the invention, after each cluster is got, it can also gather for described each
UGC videos in class carry out Denoising disposal.Obtain video duration respectively first, and it is default to judge whether video duration is located at
Duration interval within, for example, for the cluster of a certain portion's TV play " expert detective Di Ren outstanding ", each of which collection (i.e. each UGC
Video) duration all at 40 minutes or so, therefore can now set duration interval be (35,45), if some UGC video
Duration be located at the interval outside, then the UGC videos may not be a certain collection in the TV play, for example some UGC video
When a length of 10 minutes, then the UGC videos may be film clips, now the UGC videos can then be deleted.Therefore, as some UGC
When the video duration of video is located at outside default duration interval, the UGC videos can be deleted from the cluster belonging to it, from
And further improve the accuracy of UGC videos in each cluster.
Step 305, description information is generated respectively for the UGC videos in each described cluster, and to the description information
It is ranked up.
After above-mentioned processing is carried out to each cluster, then can respectively it be given birth to for the UGC videos in each described cluster
It is ranked up into description information, and to the description information, to generate the corresponding UGC video recommendations list of the cluster.
In one preferred embodiment of the invention, the step 305 can include following sub-step：
Sub-step b1, is extracted according to preset rules from video title respectively for the UGC videos in each described cluster
Video set number；
Sub-step b2, the description information of the UGC videos is defined as by the video set number of UGC videos；
Sub-step b3, ascending sort or descending are carried out for the video set number of the UGC videos in each described cluster respectively
Sequence.
In one preferred embodiment of the invention, video name and video set number can be included in the video title,
Video set number can be extracted from video title according to the orderly pattern base pre-established.Pattern is to refer to enter video title
A set of criterion of row cutting, is usually what is formed according to data analysis, and constantly adds and safeguard.According to data analysis,
Most collection of drama class video council is just like the naming method of " xxx yy collection " or " xxxyy ", and " xxx " is word, and " yy " is
Numeral or date, therefore " xxx " therein can be regarded as video name, " yy " therein is regarded as into video set number.Cause
This, can extract numeral or date " yy " in the embodiment of the present invention according to which from video title, i.e., as video set number.
After extracting video set number in video title, you can the video set number is defined as into retouching for correspondence UGC videos
Information is stated, the description information can either make a distinction the UGC videos with other UGC videos in being clustered belonging to it, can be with
Characterize the correspondence order of UGC videos.And hence it is also possible to enter respectively for the video set number of the UGC videos in each described cluster
