• Amazon Dataset [McAuley’15]
– Also Bought (AB): Users bought 𝑥 also bought 𝑦 across sessions;
– Also Viewed (AV): Users viewed 𝑥 also viewed 𝑦;
– Bought Together (BT): Users frequently bought 𝑥 and 𝑦 (𝑥 and 𝑦 were purchased as
part of a single basket);
– Buy after Viewing (BV): Users who viewed 𝑥 eventually bought 𝑦.
