A Graph Neural Network Social Recommendation Algorithm Integrating the Multi-Head Attention Mechanism

Abstract: Collaborative filtering recommendation systems are facing the data sparsity problem associated with interaction data, and social recommendations introduce user social information to alleviate this problem. Existing social recommendation methods cannot express the user interaction interest and social influence deeply, which limits the recommendation performance of the system. To address this problem, in this paper we propose a graph neural network social recommendation algorithm integrating multi-head attention… Show more

“…We have pointed out in the previous section some of the classic ways of dealing with the problems that are the subject of this work and their main drawbacks. More recent works focus on incorporating social information to address a wide variety of issues that affect the quality of recommendations [25] or resort to newer techniques such as GNN-based methods [19,26], which are also not without weaknesses.…”

“…Recent research is moving toward the application of deep learning algorithms and Graph Neural Networks (GNN) [19], which provide good results when the volume of data is very large since they are endowed with a great ability to extract the complex relationships between users and items from large datasets. However, the target scenarios of this work are precisely those in which there is a scarcity of data, such as users with unusual tastes (gray sheep) as well as users with few interactions with the items (cold start).…”
