Cross-Domain Recommender Systems

Abstract: The proliferation of e-commerce sites and online social media has allowed users to provide preference feedback and maintain profiles in multiple systems, reflecting a variety of their tastes and interests. Leveraging all the user preferences available in several systems or domains may be beneficial for generating more encompassing user models and better recommendations, e.g., through mitigating the cold-start and sparsity problems in a target domain, or enabling personalized crossselling recommendations for it… Show more

“…More diverse outcomes can be obtained by gathering rapidly additional information on users' preferences. This can be achieved by actively eliciting the user to make more informative choices [31], by integrating information from other user activities [5], or by using hybrid techniques to combine recommendations obtained by different methods [24]. As an alternative to these techniques, one can leverage the additional information to construct a network and run a standard diffusion-based algorithm on it.…”

“…This problem has been addressed from various perspectives in different research areas. It has been tackled by means of user preference aggregation and media-tion strategies for the cross-system personalization problem in user modeling [1,3,67,12], as a potential solution to mitigate the cold-start and sparsity problems in recommender systems [16,68,71,24] and as a practical application of knowledge transfer in machine learning [27,45,55].…”

“…Cross-domain recommender systems use multiple domains to generate recommendations, which can be categorized based on domain levels [4,5] Depending on whether overlapping occurs in the set of users or items [7], there are four situations that enable cross-domain recommendations: a) no overlap between items and users, b) user sets of different domains overlap, c) item sets overlap, and d) item and user sets overlap.…”
