In this paper a new proposal for memory-based Collaborative Filtering algorithms is presented. In order to compute its recommendations, a first step in memory-based methods is to find the neighborhood for the active user. Typically, this process is carried out by considering a vector-based similarity measure over the users’ ratings. This paper presents a new similarity criteria between users that could be used to both neighborhood selection and prediction processes. This criteria is based on… CONTINUE READING
