    • A computer-implemented method and display advertising server network for serving impression opportunities to a frequency-capped guaranteed delivery contract in a system for delivery of display advertising to a user. The method includes steps for receiving, from a computer, an event predicate and a user ID corresponding to the user, retrieving, from an index engine, a set of eligible frequency-capped contracts, wherein an eligible contract comprises at least one target predicate matching at least a portion of the event predicate, and probabilistically selecting for serving, in a computer, the booked contract having a frequency cap specification, only when the selected frequency-capped contract can be served to the user without violating the frequency cap specification. Exemplary embodiments include generating a pseudo-random number sequence, and then selecting a particular pseudo-random number from the series of pseudo-random numbers, the selected particular pseudo-random number being based on the user ID, a visit count, a URL.
    • 一种计算机实现的方法和显示广告服务器网络,用于向系统中的用于向用户传送显示广告的频率上限的保证递送合同提供展示机会。 该方法包括从计算机接收与用户相对应的事件谓词和用户ID的步骤,从索引引擎检索一组合格的频率上限合同,其中符合条件的合同包括至少一个目标谓词匹配 至少部分事件谓词,并且在计算机中概率地选择用于服务具有频率上限规范的预约合同,只有当所选择的频率上限的合同可以在不违反频率上限规范的情况下被提供给用户时。 示例性实施例包括生成伪随机数序列,然后从所述一系列伪随机数中选择特定的伪随机数,所选择的特定伪随机数基于用户ID,访问次数,URL。
