Problems solved by technology

However, to some extent, traditional recommendation methods cannot truly understand user preferences
It can only judge whether a user likes a resource, but cannot tell what characteristics of the resource the user is interested in.

Embodiment Construction

[0034] The invention discloses a recommendation method that expands tags through semantics and related relationships and combines time degradation. It is applied to a recommendation system that uses tags to identify resources. First, the weight of each tag is calculated in combination with time degradation to find out what the user is interested in. tags, and expand the tags through semantic relationship and related relationship, and then generate a resource recommendation list for users according to different tag weights. The present invention uses tags to identify resources to more accurately grasp the user's points of interest; adjust the tag weight through time degradation to be closer to the user's interest change trend; expand tags through semantics and correlations to find more suitable resources for recommendation . Those skilled in the art can refer to Figure 5 The principle shown.

Abstract

The invention provides a control method for recommending resources through tag extension, which comprises the following steps: a, determining the weight of a candidate extension tag; b, extending the candidate extension tag to generate an extended tag; c, determining the weight of the extended tag; and d, recommending resources according to the weight of the extended tag. The invention also provides a corresponding control device. The method is a recommending method combining tag extension by semanteme and related relationships and time degradation. The method has the advantages of grasping users' interests more accurately, following trend of interest change of users and finding proper resources more easily.

Description

technical field [0001] The invention relates to the technical field of tag-based recommendation, in particular to a recommendation method that expands tags through semantics and correlations and combines time degradation. Background technique [0002] With the advent of the information age, network information has grown exponentially, and we are prone to the phenomenon of "information overload" and "information confusion" when we search for relevant information on the Internet. The birth of personalized service technology has provided great help for people to find the most valuable resources from the information explosion network. [0003] There are two traditional recommendation methods, content-based filtering and collaborative filtering. The former generates a recommendation list by finding similar resources with higher ratings from users, and the latter generates recommendation lists by finding resources with higher ratings from the user's nearest neighbors. The recomm...
