Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
The disclosed by the invention one keyword method to set up that embodiments provides a kind of video album, in order to according to the file name of each video file comprised in this video album and file keyword, for this video album Lookup protocol keyword, realize the Lookup protocol of video album keyword.As shown in Figure 1, in the embodiment of the present invention, a kind of keyword method to set up of video album comprises step S10-S30:
The file keyword that step S10, the file name obtaining all video files comprised in video album and each video file are corresponding respectively;
In the embodiment of the present invention, by traveling through corresponding video album, obtain all video files that this video album comprises, thus read out the file name of all video files in this video album, and each video file distinguish corresponding file keyword.
Step S20, to obtain described video album in described file name and file keyword carry out cluster, find out the classification that weight is maximum;
After getting the file name and file keyword that in this video album, all video files are corresponding, to the cluster that the above-mentioned file name obtained and file keyword are carried out semantically, thus the classification that after finding out cluster, weight is maximum; Also can be understood as, find out the classification that hit rate is maximum.
In one embodiment, as shown in Figure 2, described step S20 may be embodied as step S201-S203 as described below:
Video file in step S201, traversal video album, obtains in described video album the file name of all video files comprised and the file keyword of each video file difference correspondence;
Step S202, respectively participle is carried out to the All Files title of described video file obtained and file keyword, obtain the word segmentation result that each video file is corresponding;
Step S203, the cluster of carrying out semantically to word segmentation result, find out the classification that weight is maximum.
In the embodiment of the present invention, when being got in this video album the file name of all video files comprised by the video file in traversal video album, and during the corresponding respectively file keyword of each video file, Chinese word segmenting is carried out to the above-mentioned file name obtained and file keyword, obtains comprising the notional word of the types such as noun and comprising the function word of the types such as function word.Based on word segmentation result, to the cluster that all words in the word segmentation result obtained carry out semantically, find out the classification that weight is maximum; Also can be understood as, find out the classification that hit rate is maximum.
Step S30, the word in classification maximum for weight is set to the keyword of described video album.
After finding out the maximum classification of weight by execution above-mentioned steps S10 and step S20, using the keyword of the word in classification maximum for this weight as described video album.
In one embodiment, the word in classification maximum for the weight of classification corresponding for this video album and acquisition can be combined, and using the word that obtains after the combination keyword as this video album; As shown in Figure 3, described step S30 may be embodied as step S301-S302 as described below:
Step S301, obtain the visual classification at described video album place;
Step S302, the word in described visual classification and the maximum classification of weight is set to jointly the keyword of described video album.
In the embodiment of the present invention, for each video file comprised in this video album, after getting core word corresponding to each video file, " word in the classification that the visual classification+weight at video album place is maximum " is combined into a character string, by combining the above-mentioned character string obtained, be set to the keyword of this video album.Such as, the visual classification that this video album is corresponding is " light music ", word in the classification that in this video album, weight is maximum is respectively: Zheng, piano music, violoncello and urheen, then combined by the word in classificating word corresponding for this visual classification and the maximum classification of weight, the keyword of this video album obtained is: light music Zheng piano music violoncello urheen.
In the embodiment of the present invention, consider the character length of the keyword that video album is corresponding, when the keyword of generating video special edition, pre-set a length threshold, thus by this length threshold preset as a reference, the keyword that this video album is corresponding is set.
In one embodiment, as shown in Figure 4, described step S30 may be embodied as step S303-S305 as described below:
Whether step S303, the character length sum of all words judged in the classification that weight is maximum are greater than default length threshold; If be not more than default length threshold, then perform step S304; If be greater than default length threshold, then perform step S305;
Step S304, all words in classification maximum for weight are all set to the keyword of described video album;
Step S305, according to the length threshold preset selected part word from all words the maximum classification of weight, and the part word chosen is set to the keyword of described video album.
In the embodiment of the present invention, if when not limiting the length of keyword corresponding to video album, then direct all words in classification maximum for weight are all set to keyword corresponding to this video album.If to the limited length timing of keyword corresponding to video album, then according to certain selection rule, in all words from the classification that weight is maximum, pick out the part word meeting length keywords and limit, and using the above-mentioned part word that the selects keyword as this video album.
In one embodiment, according to the relevance of the word in the maximum classification of weight and this video album, the word that relevance is little can be rejected.As shown in Figure 5, described step S305 may be embodied as step S351-S352 as described below:
Step S351, according to order from back to front, stop word one by one in all words from the classification that weight is maximum, until the character length sum of residue word is not more than default length threshold;
Step S352, the residue word after deleting is set to the keyword of described video album.
In the embodiment of the present invention, according to the length threshold preset from all words the maximum classification of weight during selected part word, can according to order from back to front, all words in the classification maximum to weight are deleted one by one.
In the embodiment of the present invention, for the word in the classification that weight is maximum, owing to being that word maximum for relevance is arranged in foremost, and according to relevance size, arrange corresponding word from front to back; Therefore, when the character length of the keyword of video album is greater than default length threshold, delete the word in the maximum classification of weight from back to front one by one, and the residue word in classification maximum for this weight after deleting is set to the keyword of described video album, thus be met the keyword of character length requirement.
