We start the journey with the important concept in recommender systems—collaborative filtering (CF), which was first coined by the Tapestry system [Goldberg et al., 1992], referring to “people collaborate to help one another perform the filtering process in order to handle the large amounts of email and messages posted to newsgroups”.
