Abstract

The invention discloses a tag recommendation method and system. The method comprises the following steps: obtaining a total tag set marked by all users on all projects; discovering the maximum frequent item set in the total tag set of the system by using the Apriori algorithm; setting the maximum frequent item set of the system as a new identifier; replacing the maximum frequent item set in the first tag set of the system with the new identifier of the system to form a second tag set; corresponding the users, the projects and the second tag set to generate user-project-tag three-dimensional tensor data, and setting an association weight of the three components as 1; decomposing the three-dimensional tensor data of the system by using the HOSVD algorithm to obtain the weight value of a tag marked by each user for each project; and recommending a tag with a high weight value to the first user, so that the user uses the tag to mark the project, wherein the user is the user who tags the project for the first time. By adoption of the method or system provided by the invention, the tag classification can be more precise, the accuracy of the recommendation system is improved, and the hit rate is gradually increased.

Description

technical field [0001] The invention relates to the field of personalized recommendation, in particular to a tag recommendation method and system. Background technique [0002] Nowadays, the development of Web technology is advancing by leaps and bounds. Users can mark a project with multiple different tags on a variety of network platforms, especially in the application of recommendation systems on various platforms. The system uses tags to explore each user's preferences. feature, when a user tags an item that has not been tagged, it can more effectively recommend suitable tags to the user for the user to tag, helping users quickly find the tags they are satisfied with. Items are objects that users tag, such as movies, videos, articles, and so on. Most of the previous recommendation algorithms were researched on the user-item scoring matrix data based on the binary relationship. With the addition of tag data, the processing of ternary relationship data composed of users, ...
