Abstract

The invention discloses an evaluation method and device of microblog-platform-oriented topic recommendation. The method includes the following steps that multiple pieces of microblog text in a microblog platform are obtained from the internet; the multiple pieces of microblog text are subjected to word dividing; word frequencies of the multiple pieces of microblog text subjected to word dividing are obtained to obtain the microblog content; according to the microblog content, unsupervised topic recommendation information is obtained; according to the Euclidean distance between the word vector of the unsupervised topic recommendation information and the word vector of a preset integrated testing topic, and the evaluation result is obtained. By means of the evaluation method in the embodiment, the recommendation topic obtained with the unsupervised method can be automatically evaluated, the unsupervised topic recommendation method of the microblog platform is effectively and automatically evaluated and detected, the effectiveness of the unsupervised method is determined accordingly, labor can be saved, and the evaluation result is more persuasive.

Description

technical field [0001] The invention relates to the fields of computer application technology and social network technology, in particular to an evaluation method and device for topic recommendation on a microblog platform. Background technique [0002] The personalized recommendation system refers to the establishment of a binary relationship between the user and the information product, using the user's past selection process or similarity relationship with other users to dig out the potential objects of interest of the user, and then carry out personalized recommendation system. recommended system. A complete recommendation system consists of three parts: recording module (behavior of mobile phone user information), analysis module (analyzing user model) and recommendation algorithm modeling. Among them, the recommendation algorithm module is the core part. According to the research results of foreign scholars, personalized recommendation algorithms can be mainly divide...
