Academic Recommendation System Based on Knowledge Graph and Semantic Information
摘要
Abstract
In the diverse domains of the Internet,facing the ever-increasing volume of data,there is a growing need for recom-mendation systems to provide users with personalized information.Utilizing knowledge graphs can enhance the accuracy,diver-sity,and interpretability of these systems.Addressing the current methods'limitations in accurately capturing genuine user pref-erences during propagation,and their lack of attention to the utility of semantic information,this paper proposes an advanced pa-per recommendation algorithm based on semantic features and knowledge graphs.This method employs the BERT model to ex-tract semantic features from paper abstracts,and uses knowledge graphs for collaborative propagation to obtain entity representa-tions of users and items.During propagation,user preferences are accurately transmitted through multi-head attention,and an attention aggregation network is differentiated between entity representation sets at each layer,the importance of initial informa-tion is emphasized.Performance evaluations on three public datasets demonstrate that the model proposed in this paper,com-pared to the selected optimal baseline models,achieves an increase of 0.010、0.018 and 0.007 in AUC,and 0.007、0.008 and 0.008 in F1 score,respectively,thereby showing the effectiveness and the superiority of the algorithm proposed in this paper.关键词
