摘要： Among other disclosed subject matter, a computer-implemented method for associating an entity with a category includes determining a probability value for each of at least a subset of a plurality of categories, the probability value representing a likelihood that an identified entity belongs to the respective category and determined using information about the entity. The method includes identifying one of the plurality of categories for the entity using the probability value and a rule set for the plurality of categories that is based on training data.

摘要： An e-commerce price index is constructed and maintained based on consumer actions in connection with one or more e-commerce websites. A data collector software module collects information regarding products sold or available for sale online, including a price and rate of clicks received for each product on the website(s). An index software module analyzes the collected information to construct the price index. Specifically, the index software module scrubs the collected information to remove outliers and fill in gaps and calculates a click-weighted average price by product category and day. The index module generates the price index by aggregating and normalizing the calculated click-weighted average prices. The index software module can compute the e-commerce price index on a virtually real-time basis. Thus, the e-commerce price index can provide useful information about online pricing trends far earlier than traditional indices.

摘要翻译： 根据与一个或多个电子商务网站相关的消费者行为，构建和维护电子商务价格指数。 数据收集器软件模块收集有关在线销售或可供销售的产品的信息，包括网站上每个产品的点击价格和点击率。 索引软件模块分析收集的信息以构建价格指数。 具体来说，索引软件模块将所收集的信息进行擦除以消除异常值并填补差距，并按产品类别和日期计算点击加权平均价格。 索引模块通过聚合和归一化计算的点击加权平均价格来生成价格指数。 索引软件模块可以实时计算电子商务价格指数。 因此，电子商务价格指数可以提供比传统指数更早的在线定价趋势的有用信息。
