    • Two items are determined to be similar to each not only based on previous actual user behavior, but also based on the observed relatedness of the characteristics of those two items. A first characteristic and a second characteristic are determined to have some affinity for each other if a high proportion of users who select items having the first characteristics also select items that have the second characteristic, and vice-versa. Two items having characteristics with high affinity for each other are determined to have some similarity to each other, even if very few or no users who selected one of those items ever selected the other of those items. A first item that is determined to be sufficiently similar to second item in this manner may be recommended to a user who has selected the second item as potentially also being of interest to that user.
    • 确定两个项目与每个项目类似,不仅基于以前的实际用户行为,而且还基于所观察到的这两个项目的特征的相关性。 如果选择具有第一特征的项目的高比例的用户也选择具有第二特征的项目,则第一特征和第二特征被确定为彼此具有一些亲和力,反之亦然。 具有彼此具有高亲和力特征的两个项目被确定为彼此具有一些相似性,即使选择了这些项目中的一个的用户很少或没有选择其中一个项目。 可以向已经选择第二项目的用户潜在地也对该用户感兴趣的用户推荐被确定为以这种方式与第二项目充分相似的第一项目。

    • An improved system and method for online advertising driven by predicting user interest is provided. An advertising demand engine may be provided for selecting advertisements to be served to a user for display with requested content. An advertisement may be correlated to an advertisement previously selected by a user or by other users in the user's segment. An advertising correlation engine may be provided for correlating an advertisement to another advertisement using collaborative filtering, an advertising clustering engine may be provided for clustering correlated advertisements using item-based collaborative filtering, and a user correlation engine may be provided for segmenting users by selected advertisements and creating a cluster of advertisements associated with each cluster of users. Correlated advertisements that are selected may be allocated web page placements and then served to a user for display with requested content.
    • 提供了一种通过预测用户兴趣推动的改进的在线广告系统和方法。 可以提供广告需求引擎用于选择要被提供给用户的广告以便显示所请求的内容。 广告可以与先前由用户或用户区段中的其他用户选择的广告相关联。 可以提供广告相关引擎,用于使用协作过滤将广告与另一广告相关联,可以提供广告聚类引擎用于使用基于项目的协作过滤来聚类相关联的广告,并且可以提供用户相关引擎,用于通过选择的广告来分割用户 以及创建与每个用户群集相关联的广告群集。 所选择的相关广告可以被分配网页展示,然后被提供给用户以显示所请求的内容。
