TL;DR

An efficient collaborative filtering method, called RecTree (which stands for RECommendation Tree), that addresses the scalability problem with a divide-and-conquer approach and outperforms the well-known collaborative filter, CorrCF, in both execution time and accuracy.

Abstract

Many people rely on the recommendations of trusted friends to find restaurants or movies, which match their tastes. But, what if your friends have not sampled the item of interest? Collaborative filtering (CF) seeks to increase the effectiveness of this process by automating the derivation of a recommendation, often from a clique of advisors that we have no prior personal relationship with. CF is a promising tool for dealing with the information overload that we face in the networked world.
