摘要:

在社交网络平台上,用户的行为基于他/她的个人兴趣,或者受到他/她的朋友的影响。在文献中,通常对用户的个人偏好或他们的社会影响偏好进行建模。在本文中,我们提出了一种新的深度学习模型SocialTrans,用于整合这两种类型的偏好。SocialTrans由三个模块组成。第一个模块是基于一个多层的Transformer模型的用户的个人喜好。第二个模块是一个多层图注意力神经网络(GAT),它被用来建模的社会影响力之间的社交网络的朋友。最后一个模块融合用户的个人偏好和社会影响的偏好,以产生推荐。我们的模型可以有效地适应大规模的数据,我们部署了SocialTrans在中国的一个主要的文章推荐系统。在三个数据集上的实验验证了该模型的有效性,并表明它优于最先进的社会推荐方法。

英文摘要:

On social network platforms, a user's behavior is based on his/her personal interests, or influenced by his/her friends. In the literature, it is common to model either users' personal preference or their socially influenced preference. In this paper, we present a novel deep learning model SocialTrans for social recommendations to integrate these two types of preferences. SocialTrans is composed of three modules. The first module is based on a multi-layer Transformer to model users' personal preference. The second module is a multi-layer graph attention neural network (GAT), which is used to model the social influence strengths between friends in social networks. The last module merges users' personal preference and socially influenced preference to produce recommendations. Our model can efficiently fit large-scale data and we deployed SocialTrans to a major article recommendation system in China. Experiments on three data sets verify the effectiveness of our model and show that it outperforms state-of-the-art social recommendation methods.
