Abstract
Collaborative or “Social” filtering has been successfully deployed over the years as a technique for analysing large amounts of user-preference knowledge to predict interesting items for an individual user. The black-box nature of most
collaborative filtering (CF) applications leave the user wondering how the system arrived at its recommendation. In this paper we introduce PeerChooser, a collaborative recommender system with an interactive interface which provides the user not only an explanation of the recommendation process, but the opportunity to
manipulate a graph of their peers at varying levels of granularity, to reflect aspects of their current requirements. PeerChooser’s
prediction component reads directly from the graph to yield the same results as a benchmark recommendation algorithm.
Users then improve on these predictions by tweaking the graph in various ways. PeerChooser compares favorably against the
benchmark in live evaluations and equally well in automated accuracy tests.
