Abstract

Making e ective recommendations from a domain consisting of millions of ratings is a major research challenge in the application of machine learning. Kernel Mapping Recommender (KMR) algorithms have been proposed providing state-of-the-art performance. In this paper, we show how context information can be added to KMR algorithms. We consider the trusted friends of a user as their social context and show how this information can be used to provide more personalised, refined, and trustworthy recommendations. The limited set of friends; however, restricts the amount of data available to create useful recommendations. This paper sheds light on this issue and specifically on the amount of friends necessary to get satisfactory recommendations.
