摘要:

为了解决推荐系统(RS)中长期存在的数据稀疏性问题,提出了跨域推荐(CDR)方法,利用较丰富域中相对丰富的信息来提高稀疏域中的推荐性能。虽然CDR近年来得到了广泛的研究,但缺乏对现有CDR方法的系统综述。为了填补这一空白,在本文中,我们提供了一个全面的审查现有的CDR方法,包括挑战,研究进展和未来的发展方向。具体而言,我们首先总结了现有的CDR方法分为四种类型,包括单目标CDR,多域推荐,双目标CDR,和多目标CDR。然后,我们提出了这些CDR方法的定义和挑战。接下来,我们提出了一个全面的分类和新的分类法,这些方法和报告的研究进展。最后,我们分享了CDR中几个有前途的研究方向。

英文摘要:

To address the long-standing data sparsity problem in recommender systems (RSs), cross-domain recommendation (CDR) has been proposed to leverage the relatively richer information from a richer domain to improve the recommendation performance in a sparser domain. Although CDR has been extensively studied in recent years, there is a lack of a systematic review of the existing CDR approaches. To fill this gap, in this paper, we provide a comprehensive review of existing CDR approaches, including challenges, research progress, and future directions. Specifically, we first summarize existing CDR approaches into four types, including single-target CDR, multi-domain recommendation, dual-target CDR, and multi-target CDR. We then present the definitions and challenges of these CDR approaches. Next, we propose a full-view categorization and new taxonomies on these approaches and report their research progress in detail. In the end, we share several promising research directions in CDR.
