For recommender systems, the ultimate target is to [[stimulate the purchasing activities of potential customers by retrieving the items that catch their personalized interests among the overloaded information. With this goal, such systems can be classified as substitute and complementary recommenders: substitute recommenders offer similar items to the source, complementary recommenders suggest items that are dissimilar to the source but are often sold with it as a companion item or service (such as a mobile phone (source) and case (complementary) ). ...

For example, while a user is browsing mobile phones, it might make sense to recommend other phones, but once they buy a phone, we might instead want to recommend batteries, cases, or chargers. In economics, these two types of recommendations are referred to as substitutes and complements: substitutes are products that can be purchased instead of each other, while complements are products that can be purchased in addition to each other. Such relationships are essential as they help us to identify items that are relevant to a user's search. ...
