Several applications are built around sharing information by leveraging social network connections. For example, in social buying sites like Groupon, a deal is usually forwarded to interested recipients through their social graph. A primary goal is to improve user satisfaction by maximizing the relevance of the shared message to the target audience. In order to suggest more personalized products, one should consider offering not only accurate but also diverse recommendations, since diversification plays an important factor in increasing the users's satisfaction. In this work, we address this problem by proposing a social network hyperbolic embedding that exploits both social connections and user preferences aiming at increasing both the accuracy and the diversity of recommendations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
