There is the same word number of same word with each second phrase；
Step S24 is calculated according to the first word number, the second phrase number and all corresponding same word numbers and compares phase
Like degree.
The participle that present invention can be suitably applied to English filename, Chinese file name and Chinese and English mixed file name, due in English
It in the style of writing of text, so the participle of English filename is relatively simple, is not done using space as nature delimiter between word
It explains in detail；Chinese and English mixed file name segment when mainly first by Chinese and English distinguish, and respectively to Chinese and English into
Row participle；And Chinese only word, sentence and section can simply be demarcated by apparent delimiter, only word none in form
Delimiter mainly explains Chinese Word Automatic Segmentation so the participle of Chinese is complex below, and Chinese Word Automatic Segmentation is by a Chinese character
Sequence is cut into individual word one by one, that is, continuous chinese character sequence is reassembled into word order according to certain specification
The process of column.Certainly, segmentation methods of the invention are not limited to Chinese Word Automatic Segmentation.
Chinese Word Automatic Segmentation generally comprises character match method, understanding method etc., and character match method is will according to certain strategy
Chinese character string (being equivalent to sharing video frequency filename) to be analyzed (is equivalent to file to rank with " sufficiently big " machine dictionary
Filename in table) in entry matched, if finding some character string, successful match in dictionary；Understanding method is by allowing
The understanding of computer mould personification distich, achieve the effect that identify word, basic thought be exactly participle while progress syntax,
Semantic analysis handles Ambiguity using syntactic information and semantic information；Wherein matching method applies relatively broad, the present embodiment
Using matching method, the embodiment of the present invention is illustrated with matching method below.
The filename to sharing video frequency is segmented as multiple words based on the Chinese norm of setting, specifically may is that excellent
First identify and be syncopated as in the filename to sharing video frequency it is some with obvious characteristic word (such as the verbs such as "Yes", " having ",
Word etc. that word that number is had a common boundary with Chinese character, English have a common boundary with Chinese character), using these words as breakpoint, old file name can be divided into compared with
Then small Chinese character string orderly splits Chinese character string and removes to match preset Chinese word library, identical with Chinese word library in filename to tear open
Chinese character string is as a word after point.
For example, the file to sharing video frequency is entitled " 2008 Beijing Olympic Games year Bird's Nest gymnasium opening ceremony live broadcast ",
It can then be segmented by segmentation methods as " 2008 ", " year ", " Beijing ", " Olympic Games ", " Bird's Nest ", " gymnasium ", " opening ceremony ",
" scene ", " live streaming " nine words, this nine words collectively constitute the first phrase, the i.e. collection that the first phrase is this nine words
It closes, using the word number in the first phrase as the first word number, i.e. the first word number is 9.
Include the filename of three sharing video frequencies in list of file names, is filename one, filename two and file respectively
Name three, filename is first is that " 2008 Beijing Olympic Games ", corresponding second phrase A are { " 2008 ", " year ", " Beijing ", " Olympic Games
Meeting " }；Filename second is that " Beijing Olympic Games in-situ match ", corresponding second phrase B be " Beijing ", " Olympic Games ", " match ",
" scene " }；Filename is third is that " 2008 Opening Ceremony of the Games ", corresponding second phrase C are { " 2008 ", " Olympic Games ", " opening
Formula " }, and then show that the number (i.e. the second phrase number) of the second phrase is 3.
Then the word in the first phrase is compared with the word in the second phrase A one by one, identical word has
" 2008 ", " year ", " Beijing " and " Olympic Games " four identical words, so being 4 with word number A；Similarly the first phrase and
The same word number B of two phrase B is 3, and the same word number of the first phrase and the second phrase C are 3.Then according to the first word number (value
To find out the first phrase and the primary similarity A of the second phrase A 9) and with word number A (value is 4), according to the first word number (value
To find out the first phrase and the primary similarity B of the second phrase B 9) and with word number B (value is 3), according to the first word number (value
To find out the first phrase and the primary similarity C of the second phrase C 9) and with word number C (value is 3)；As primary similarity A is
24/29=1/25, primary similarity B is 23/29=1/26, primary similarity C is 23/29=1/26。
Finally according to primary similarity A, primary similarity B, primary similarity C and the second phrase number, three primary are calculated
The average value of similarity, the average value be to sharing video frequency filename compared with listed files similarity, such as it is more similar
Degree=(1/25+1/26+1/26)/3=1/48.
In the present embodiment, according to the first word number to sharing video frequency, the second phrase number in list of file names and institute
There is corresponding same word number, is calculated to compare similarity and provide a kind of simple, feasible, accurate relatively similarity calculation and calculate
Method, further improve judge to sharing video frequency whether the accuracy of upload server.
Further, on the basis of smart television video sharing method first embodiment of the present invention, smart television is proposed
Video sharing method fourth embodiment, referring to Fig. 5, in the fourth embodiment, step S30 includes:
Step S31 obtains current time, the video length to sharing video frequency if comparing similarity less than similarity threshold
With video file size；
Step S32 is obtained according to similarity, current time, video length and video file size is compared to sharing video frequency
Broadcasting weighted value；
Step S33 will play weighted value and be packaged into encapsulation program stream to sharing video frequency so that server receives encapsulation
It is ranked up and is issued according to collating sequence to encapsulation program stream is not played respectively according to playing weight after program stream.
When comparing similarity less than similarity threshold, show a possibility that existing on the server to sharing video frequency compared with
It is small, and then obtain current time, the video length to sharing video frequency and video file size, then according to compare similarity, when
Preceding time, video length and video file size obtain broadcasting weighted value to sharing video frequency, wherein it is higher to compare similarity,
Show that the video degree of correlation uploaded to sharing video frequency and users other on server is higher, that is, shows that this is more flowed to sharing video frequency
Row, therefore it is directly proportional to weight is played to compare similarity；The default historical time of current time distance is remoter, shows to get over to sharing video frequency
Novelty, therefore to play weight more rearward bigger for current time；Video length is longer, shows that the integrality to sharing video frequency is higher, therefore
Video length is directly proportional to weight is played；Video file size is smaller, shows that the compression degree to sharing video frequency is higher, therefore video
File size is inversely proportional with weight is played.Furthermore compare shared by similarity, current time, video length and video file size
Playing weight proportion can be arranged according to demand.Finally one is encapsulated in the broadcasting weighted value of sharing video frequency and to sharing video frequency
Rise, collectively form encapsulation program stream, server receive this include play weighted value encapsulation program stream when, server according to
It plays weighted value and treats to play video and uploaded and do not play video and play out weighted value descending sort, to form waiting team
Column.
Specifically, step S32 are as follows: according to WP=S* ((T-T0)/1000) * (F/L), obtain the right of broadcasting to sharing video frequency
Weight values, wherein WP is to play weighted value, and S is to compare similarity, and T is current time, and T0 is default historical time, and F is video text
Part size, L are video length.
Current time and default historical time are UTC (Coordinated Universal Time, the Coordinated Universal Time(UTC))
