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 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-S40:
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, 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;
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.
Step S30, the word segmentation result that obtains after participle, extract one or more high frequency words that the frequency of occurrences is the highest;
After participle is carried out to the All Files title of described video file obtained and file keyword, based on the word segmentation result obtained, calculate the frequency that each participle occurs, thus according to result of calculation, extract its frequency of occurrences maximal value, and then obtain one or more high frequency words corresponding to this frequency of occurrences maximal value.In the embodiment of the present invention, participle corresponding to frequency of occurrences maximal value can be one, also can have multiple.When extracting the highest participle of frequency and having one or more, using the above-mentioned participle that the extracts high frequency words as correspondence.
In one embodiment, when extracting high frequency words, the word segmentation result that can obtain after participle, extract the high frequency words that the frequency of occurrences is greater than predeterminated frequency threshold value.Such as, based on the word segmentation result obtained after participle, find out the participle that its frequency of occurrences is forward, such as, preset a described predeterminated frequency threshold value, find out the frequency of occurrences being greater than this predeterminated frequency threshold value, and obtain all participles corresponding to the frequency of occurrences being greater than described predeterminated frequency threshold value, and using the high frequency words of all participles of acquisition as correspondence.
Step S40, the described high frequency words extracted is set to the keyword of described video album.
After extracting corresponding high frequency words, using the high frequency words that the extracts keyword as this video album.
In one embodiment, classification corresponding for this video album and the high frequency words extracted can be combined, and using the word that obtains after combination as the keyword of this video album; As shown in Figure 2, described step S40 may be embodied as step S401-S402 as described below:
Step S401, obtain the visual classification at described video album place;
Step S402, described visual classification and the high frequency words that obtains are set to jointly the keyword of described video album.
In the embodiment of the present invention, after getting high frequency words corresponding to this video album, obtain the visual classification corresponding to this video album again, and then " visual classification+high frequency words at video album place " 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 ", high frequency words corresponding in this video album is respectively: Zheng, piano music, violoncello and urheen, then the above-mentioned high frequency words of classificating word corresponding for this visual classification with the correspondence got combined, 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 3, described step S40 may be embodied as step S403-S405 as described below:
Whether the character length sum of all high frequency words that step S403, judgement extract is greater than default length threshold; If be not more than default length threshold, then perform step S404; If be greater than default length threshold, then perform step S405;
Step S404, all high frequency words are all set to the keyword of described video album;
Step S405, according to the length threshold selected part high frequency words from all high frequency words extracted preset, and the part high frequency words extracted 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 high frequency words extracted are 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, from all high frequency words extracted, pick out the part high frequency words meeting length keywords and limit, and using the above-mentioned portion high frequency participle that the selects keyword as this video album.
In one embodiment, according to the relevance of all high frequency words and this video album, the word that relevance is little can be rejected.As shown in Figure 4, described step S405 may be embodied as step S451-S452 as described below:
Step S451, according to order from back to front, from all high frequency words extracted, delete high frequency words one by one, until the character length sum of residue high frequency words is not more than default length threshold;
Step S452, remaining high frequency words after deleting is set to the keyword of described video album.
In the embodiment of the present invention, the length threshold according to presetting during selected part high frequency words, according to order from back to front, can be deleted one by one all high frequency words from all high frequency words.
In the embodiment of the present invention, for all high frequency words, owing to being that high frequency words 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 corresponding high frequency words from back to front one by one, and the remaining high frequency words after deletion is set to the keyword of described video album, thus be met the keyword of character length requirement.
