    • An improved system and method for forecasting an inventory of online advertisement impressions for targeting profiles of attributes is provided. An index of advertisement impressions on display advertising properties may be built for a targeting profile of attributes from forecasted impression pools. Impression pools of advertisements sharing the same attributes and trend forecast data for web pages and advertisement placements on the web pages may be integrated to generate the forecasted impression pools. An index of several index tables may be generated from forecasted impression pools. A query may be submitted to obtain an inventory forecast of advertisement impressions for targeting profiles of attributes and the index may be searched to match forecasted impression pools for the targeted profile of attributes. Then the inventory forecast of advertisement impressions on display advertising properties may be returned as query results for the targeting profile of attributes.
    • 提供了一种用于预测用于定位属性配置文件的在线广告展示广告资源的改进的系统和方法。 可以为预测的展示池的属性的定位配置文件构建展示广告属性的广告展示的索引。 可以集成在网页上分享与网页和广告刊登位置相同的属性和趋势预测数据的广告的展示池,以生成预测的展示池。 可能会从预测的展示池生成多个索引表的索引。 可以提交查询以获得针对属性的定向配置文件的广告展示的库存预测,并且可以搜索索引以匹配针对属性的目标配置文件的预测的展示池。 然后可以返回显示广告属性上的广告展示的广告资源预测,作为属性定位配置文件的查询结果。

    • A system for advertisement inventory allocation is disclosed, including a database to store advertisement impressions. An indexer builds a plurality of index tables each associated with an attribute that is mapped to a plurality of the impressions. An impression matcher constructs a flow network including a plurality of nodes each containing impressions of at least one corresponding attribute projected to be available during a time period, a plurality of contracts each including specific requests for impressions that satisfy a demand profile during the time period, and a plurality of arcs to connect the plurality of nodes to the plurality of contracts that match the demand profile of each contract. An optimizer optimally allocates impressions from the nodes to the contracts during the time period by solving the flow network with a minimum-cost network flow algorithm that maximizes delivery of the impressions to the contracts in a way that satisfies the corresponding demand profiles and that specifies a number of impressions to flow over each of the plurality of arcs.
    • 公开了一种用于广告库存分配的系统,包括用于存储广告印象的数据库。 索引器构建多个索引表,每个索引表与映射到多个印象的属性相关联。 印象匹配器构建包括多个节点的流网络,每个节点包含预计在一段时间段内可用的至少一个对应属性的展示,每个包括在该时间段期间满足需求简档的印象的特定请求的多个合同, 以及多个弧,以将多个节点连接到与每个合同的需求曲线相匹配的多个合同。 优化器通过以最小成本网络流算法求解流网络来最佳地将节点间的展示分配到合同中,该算法最大限度地以满足相应需求简档的方式向合同交付展示,并指定 在多个弧中的每一个上流动的展示次数。

    • Data quality measurement is provided for use in a data processing stream, which comprises at least one upstream data processing system and at least one downstream data processing system. An input alert component can be used to provide a measurement of data prior to its input to a data processing system (e.g., a downstream data processing system or an upstream data processing system). An output alert component can be used to provide a measurement on data output by a data processing system. A self-consistency component can be used to measure consistency between items of input, or output data. An end-to-end component can be used to measure data quality using data items from both input data and output data. These components can be used in some combination, or independent of the other, and in any order. In addition, the data quality measurements can be performed separate from that processing performed by either the upstream or downstream processing system.
    • 提供数据质量测量用于数据处理流中,数据处理流包括至少一个上游数据处理系统和至少一个下游数据处理系统。 输入警报组件可用于在数据处理系统(例如,下游数据处理系统或上游数据处理系统)输入之前提供数据测量。 可以使用输出警报组件来提供由数据处理系统输出的数据的测量。 自我一致性组件可用于测量输入项或输出数据之间的一致性。 端到端组件可用于使用来自输入数据和输出数据的数据项来测量数据质量。 这些组件可以以某种组合使用,或独立于另一种组合,并以任何顺序使用。 此外,数据质量测量可以与上游或下游处理系统执行的处理分开执行。
