基于多视图对比学习的多行为推荐
Multi-behavior Recommendation Based on Multi-view Contrastive Learning
摘要
Abstract
In order to effectively extract semantic and structural information from user behavior graphs and fully utilize the complex dependencies between nodes,we propose a multi-behavior recommendation method(MVCL)based on multi-view contrastive learning.MVCL constructs a meta-path view and structure view to model high-order semantic information and local structural information between nodes respectively.In addition,we use self-supervised techniques and propose a cross-view contrastive learning mechanism,which enables the two views to collaborate with each other.Compared with multiple baseline models on real-world datasets,MVCL achieves the highest normalized discounted cumulative gain improvement of 24.7%.Experimental results demonstrate that MVCL outperforms other models and can learn more effective node representations.关键词
