The content of each item is represented as a set of descriptors or terms, typically the words that occur in a document. Chapter 3 Content-based Recommender Systems: State of the Art and Trends Pasquale Lops, Marco de Gemmis and Giovanni Semeraro Abstract Recommender systems have the effect of guiding users in a personal-ized way to interesting objects in a large space of possible options. Content-based. Another common approach when designing recommender systems is content-based filtering. Content-based filtering methods are based on a description of the item and a profile of the user’s preferences.
