Data Set Information:

Two approaches were tested: a collaborative filter technique and a contextual approach.
(i) The collaborative filter technique used only one file i.e., rating_final.csv that comprises the user, item and rating attributes.
(ii) The contextual approach generated the recommendations using the remaining eight data files.
