基于属性感知的序贯推荐算法

Attribute-aware Diversification for Sequential Recommendations

Anton Steenvoorden, Emanuele Di Gloria, Wanyu Chen, Pengjie Ren, Maarten de Rijke

摘要:

用户更喜欢多样化的推荐而不是同质化的推荐。然而,大多数以前的工作顺序推荐不考虑多样性,并争取最大的准确性,导致同质的建议。在本文中,我们考虑到准确性和多样性,提出了一个属性感知的多样化顺序推荐(ADSR)。具体而言,ADSR利用可用的属性信息时,建模用户的顺序行为,同时学习用户的最有可能的项目进行交互,以及他们的属性偏好。然后,ADSR多样化的推荐项目的基础上预测的偏好的某些属性。两个基准数据集上的实验表明,ADSR可以有效地提供多样化的建议,同时保持准确性。

英文摘要:

Users prefer diverse recommendations over homogeneous ones. However, most previous work on Sequential Recommenders does not consider diversity, and strives for maximum accuracy, resulting in homogeneous recommendations. In this paper, we consider both accuracy and diversity by presenting an Attribute-aware Diversifying Sequential Recommender (ADSR). Specifically, ADSR utilizes available attribute information when modeling a user's sequential behavior to simultaneously learn the user's most likely item to interact with, and their preference of attributes. Then, ADSR diversifies the recommended items based on the predicted preference for certain attributes. Experiments on two benchmark datasets demonstrate that ADSR can effectively provide diverse recommendations while maintaining accuracy.
