    Abstract: One embodiment of the invention sets forth a mechanism for identifying similar items within a plurality of items available to a group of users. The mechanism includes identifying a first count that indicates a number of times any user has interacted with a first item included in the plurality of items and subsequently with any other item, identifying a second count that indicates a number of times any user within the has interacted with a second item included in the plurality of items after interacting with the first item, computing a probability that indicates the likelihood of a particular user interacting with the second item after interacting with the first item based on the first count and the second count, and computing a similarity score that indicates the similarity between the first item and the second item based on the probability and a popularity score associated with the second item.

    Abstract translation: 本发明的一个实施例提出了一种用于识别可用于一组用户的多个项目中的相似项目的机制。 该机制包括识别指示任何用户已经与包括在多个项目中的第一项目进行交互的次数的随后的任何其他项目的第一计数,识别表示所述用户内的任何用户已经互动的次数的第二计数 其中在与所述第一项目交互之后包括在所述多个项目中的第二项目计算指示在与所述第一项目基于所述第一计数和所述第二计数交互之后特定用户与所述第二项目交互的可能性的概率,以及 基于与第二项目相关联的概率和受欢迎程度,计算指示第一项目和第二项目之间的相似性的相似度分数。
