摘要:

随着社交平台的发展,人们越来越倾向于组合成群体参与一些活动,因此群体推荐逐渐成为一个值得研究的问题。对于群体推荐,一个重要的问题是如何通过个人的交互历史来获取群体和项目的特征表征,从而获得群体对项目的偏好。针对这一问题,我们提出了一种基于交互模式的群推荐图神经网络模型GIP 4GR。具体而言,该模型利用具有强大表示能力的图神经网络框架,在图的拓扑结构中表示群体-用户-项目之间的交互,同时通过分析图的交互模式来调整图神经网络的特征输出,得到群体和项目的特征表示,计算群体对项目的偏好。我们在两个真实世界的数据集上进行了大量的实验,以说明我们的模型的优越性能。

英文摘要:

With the development of social platforms, people are more and more inclined to combine into groups to participate in some activities, so group recommendation has gradually become a problem worthy of research. For group recommendation, an important issue is how to obtain the characteristic representation of the group and the item through personal interaction history, and obtain the group's preference for the item. For this problem, we proposed the model GIP4GR (Graph Neural Network with Interaction Pattern For Group Recommendation). Specifically, our model use the graph neural network framework with powerful representation capabilities to represent the interaction between group-user-items in the topological structure of the graph, and at the same time, analyze the interaction pattern of the graph to adjust the feature output of the graph neural network, the feature representations of groups, and items are obtained to calculate the group's preference for items. We conducted a lot of experiments on two real-world datasets to illustrate the superior performance of our model.
