摘要:

传统的推荐系统面临着数据稀疏和冷启动两个长期存在的障碍,这两个问题促进了跨域推荐(Cross-Domain Recommendation,CDR)的产生和发展。CDR的核心思想是利用从其他领域收集的信息来缓解一个领域中的两个问题。在过去的十年中,许多努力已经从事跨域推荐。最近,随着深度学习和神经网络的发展,涌现出了大量的方法。然而,关于CDR的系统调查数量有限,特别是关于最新提出的方法以及它们所解决的建议场景和建议任务。在这篇调查论文中,我们首先提出了一个两级分类的跨域推荐分类不同的推荐场景和推荐任务。然后,我们介绍和总结现有的跨域推荐方法在不同的推荐场景下,以结构化的方式。我们还组织了常用的数据集。最后,我们提供了几个潜在的研究方向,这一领域的调查。

英文摘要:

Traditional recommendation systems are faced with two long-standing obstacles, namely, data sparsity and cold-start problems, which promote the emergence and development of Cross-Domain Recommendation (CDR). The core idea of CDR is to leverage information collected from other domains to alleviate the two problems in one domain. Over the last decade, many efforts have been engaged for cross-domain recommendation. Recently, with the development of deep learning and neural networks, a large number of methods have emerged. However, there is a limited number of systematic surveys on CDR, especially regarding the latest proposed methods as well as the recommendation scenarios and recommendation tasks they address. In this survey paper, we first proposed a two-level taxonomy of cross-domain recommendation which classifies different recommendation scenarios and recommendation tasks. We then introduce and summarize existing cross-domain recommendation approaches under different recommendation scenarios in a structured manner. We also organize datasets commonly used. We conclude this survey by providing several potential research directions about this field.
