Embodiment

[0042] see figure 1 , figure 1 It is a flow chart of a tag-based automatic channel generation method provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0043] Step S101, determining the tag corresponding to a certain video;

[0044] Specifically, the certain video is any one of all videos. Determine the tag corresponding to a certain video, optionally including:

[0045] A mapping relationship between the certain video and the label is established, and a label corresponding to the certain video is determined through the mapping relationship between the certain video and the label.

[0046] Further, optionally, the mapping relationship between the certain video and the tag is implemented through a table structure or a graph structure. In order to intuitively describe the relationship between the video and the tags, the following examples illustrate, for example, the above-mentioned video is the TV series "Romance of the T...

Abstract

The invention discloses a method and device for automatically generating a channel based on labels. The method comprises the following steps: determining a label corresponding to a certain video, which is any one of all videos; calculating the number of the videos corresponding to a certain label in the labels, wherein a certain label is any one of the labels; calculating the inverse file frequency of a certain label in the labels corresponding to all the videos; calculating the video playing time of a certain video within a pre-set time slot; calculating a channel generating score of a certain label according to the number of the videos corresponding to a certain label, the inverse file frequency of a certain label in the labels corresponding to all the videos and the video playing time of a certain video within the pre-set time slot; and generating the channel by utilizing a certain label when the channel generating score of a certain label is up to a pre-set threshold value. By adopting the technical scheme provided by the invention, the channel highly satisfying user requirements can be automatically added; and thus, the method and the device are adaptive to variety requirements of users.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a tag-based channel automatic generation method and device. Background technique [0002] With the advent of the Internet era, the Internet has begun to gradually change people's entertainment and other living habits. Among them, more and more viewers watch movies, TV series, etc., and have shifted from traditional TV media to some Internet media such as video websites. [0003] Currently, video websites provide some predetermined channels for users to choose from, such as movie channels, TV drama channels, and the like. However, these predetermined channels are all fixed, and the channel information is relatively simple, so it is impossible to automatically add channels with relatively large user needs to meet the diverse needs of users. Contents of the invention [0004] In view of this, the present invention provides a label-based method and device for automatically ge...
