Embodiment 1

[0064] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a resource topic processing method in the present invention, which may specifically include:

[0065] Step 101. Determine the topic score according to the inverse text score of the tag corresponding to the topic;

[0066]In practical applications, topics are usually composed of tags, and the tags and the movies corresponding to the topics have an association relationship. Therefore, according to the above-mentioned relationship between tags and topics, and the corresponding movies between tags and topics, before using the clustering algorithm to cluster the topics in the embodiment of the present invention, first, calculate the inverse text score of the tag, that is, by counting the different tags in the movie The number of occurrences in , select the corresponding IDF (Inverse Document Frequency, inverse document frequency) function to calculate the inverse text score of the label, then dete...

Abstract

An embodiment of the invention provides a resource topic processing method and apparatus. The method comprises the steps of: determining topic scores according to inverse text scores of tags corresponding to the topics; clustering the topics according to the topic scores to obtain a target set; and determining target topics in the target set. According to the embodiment of the invention, the overlap ratio of the topics can be reduced.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for processing resource themes. Background technique [0002] In a video website, in order to facilitate browsing by users and enable users to quickly search for movies they want to watch, the movies published on the website can be tagged. Since the tags are short and feature prominent, multiple themes can be obtained by clustering the tags, and the movies contained in each topic can be similar or related, so that users can quickly browse and search easily find the movie you want to watch. [0003] For example, the tags of the movie "Carmen in Mong Kok" include: Love, Chinese, Literature, Sadness, Wong Kar-wai, Andy Lau, Maggie Cheung, etc., and the clustering algorithm can generate the movie's "Chinese love movie", "Movie directed by Wong Kar-wai" , "Movies About Love Starring Andy Lau", "Sad Literary Movies" and other themes, so that users can...
