Problems solved by technology

[0004] When recommending the most popular video of the type to which the currently playing video belongs, the correlation between the most popular video and the currently playing video may be very low, resulting in a low recommendation success rate; and when the server uses the method of calculating LD distance to recommend videos, LD The distance can only mechanically measure the difference in text editing between different video names, so that the final recommended video name may be semantically far from the currently playing video name, which will also result in low video relevance and lead to successful recommendation very low rate

Abstract

The present invention relates to the field of network technology, and discloses a file recommendation method and device. The method comprises: tokenizing a first title to obtain a first keyword set; obtaining, according to pre-set correspondence between keywords and file titles containing the keywords, at least one second title corresponding to the at least one keyword contained in the first keyword set, and obtaining a second keyword set corresponding to the at least one second title; obtaining keywords that appear both in the first keyword set and in the second keyword sets corresponding to each second title, and using the keywords as the matching keywords; obtaining the weight of the matching keywords in the first title; determining the second title to be recommended; recommending the file indicated by the second title that has been determined. The present invention determines the second title to be recommended by determining the weight of matching keywords, thereby enhancing the relevance between the file title to be recommended and the title of the currently open file, and improving the recommendation success rate.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a file recommendation method and device. Background technique [0002] In daily online activities, users are faced with all kinds of information all the time, but it is difficult to filter out the information that they are really interested in. In order to facilitate the user's screening, the server may recommend information that may be of interest to the user based on the user's browsing records, hobbies, and the like. [0003] Taking video as an example, when recommending videos, the server can recommend to the user the most popular videos of the type that the currently playing video belongs to. Hottest Videos. Alternatively, the server calculates the LD (Levenshtein Distance, edit distance) between the name of each video and the name of the currently playing video, and recommends the video with the smallest LD distance between the name and the name of the currently ...
