specific example

[0154] Set the playback duration correction interval (A, B), A=(1-20%)*Z, B=(1+20%)*Z, assuming the total duration of the current video Z=600s, then the correction interval is (480- 720s).

[0155]A user plays a video with a total video length of 600s. The first time he plays the video clip from 0-60s, and the second time he plays the video clip from 30-90s, then the accumulated playing time of the first and second times is (that is, the cumulative playing time) is 120s, because 120s The effective number of times E of the video playback is regarded as one time, the video playback is regarded as the first playback, and the effective playback duration L is regarded as a cumulative playback duration of 120s.

[0156] A specific example of calculating the quality score of video playback:

[0157] Assuming that the preset value of the playback duration is 500s, the effective playback duration of the video is 120s1 L calculates the quality score S of a single video playback, S=k 1...

[0165] A specific example of obtaining the effective playback duration of a video:

[0166] Set the playback duration correction interval (A, B), A=(1-20%)*Z, B=(1+20%)*Z, assuming the total duration of the current video Z=600s, then the correction interval is (480- 720s).

[0167] A user plays a video with a total video length of 600s. The first time he plays a video clip from 0-400s, and the second time he plays a video clip from 0-90s, the cumulative playing time of the first and second times is (i.e. cumulative playback time) is 490s, since 490s<600s and 490∈(480-720s), the effective number of times E of the video playback is considered once, the video playback is regarded as the first playback, and the effective playback duration is regarded as the current video The total duration of 600s.

[0168] A specific example of calculating the quality score of video playback:

[0169] Assuming that the preset value of the playback time is 500s, the effective playback time of t...

Embodiment 3

[0177] A specific example of obtaining the effective playback duration of a video:

[0178] Set the playback duration correction interval (A, B), A=(1+20%)*Z, B=(1-20%)*Z, assuming the total duration of the current video Z=600s, then the correction interval is (480- 720s).

[0179] A user plays a video with a total video length of 600s. For the first time, the video segment of 0-400s is played, for the second time, the video segment of 0-90s is played, and for the third time, the video segment of 100-220s is , the second and the third cumulative play duration (i.e. cumulative playback duration) are 610s, because 610s>600s and 610∈(480-720s), then the effective number of times E of the video playback is regarded as twice, the Video playback is regarded as repeated playback. The effective playback duration of the first playback is the total duration of the current video 600s, and the effective playback duration of the second playback is the duration of the third playback, which...

Abstract

The invention discloses a video quality scoring method. The method comprises the following steps of S, obtaining a video playing quality score S and a video playing effective times E; S2, establishing a relation between a video playing time coefficient D and the video playing effective times E to obtain the video playing time coefficient D; S3, calculating the video playing quality total score T according to a formula as follows: T is equal to S*D; and S4, calculating the video quality score G according to a formula as follows: G is equal to T / E. The invention also discloses a video quality scoring system. By adoption of the scoring method, the influence of fraudulent scoring by users can be effectively filtered, relatively less algorithm calculated amount is required, and the burden of a server can be relieved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for scoring video quality. Background technique [0002] With the development of video technology, a large number of videos such as animations, movies, TV dramas, and variety shows are produced every day. At the same time, with the development of Internet technology, people are provided with a more convenient way to watch a huge number of videos. YouTube, Youku and other video sites have an equivalent amount of video clips uploaded every moment, and the problem of video information overload is becoming more and more obvious, making it impossible for people to quickly obtain videos that meet their preferences. In order to deal with this problem, the video recommendation method came into being, and has become a very potential method to solve the problem of information overload in the music field. [0003] The video recommendation method is essentially...
