Abstract: A technique for representing an information need and employing one or more filters to select documents that satisfy the represented information need, including a technique of creating filters that involves (a) dividing a set of documents into one or more subsets such that each subset can be used as the source of features for creating a filtering profile or used to set or validate the score threshold for the profile and (b) determining whether multiple profiles are required and how to combine them to create an effective filter. Multiple profiles can be incorporated into an individual filter and the individual filters combined to create an ensemble filter. Ensemble filters can then be further combined to create meta filters.

Abstract translation: 用于表示信息的技术需要并采用一个或多个过滤器来选择满足所表示的信息的文档，包括创建过滤器的技术，该技术涉及（a）将一组文档划分成一个或多个子集，使得每个子集可以是 用作创建过滤配置文件或用于设置或验证配置文件的分数阈值的功能的来源，以及（b）确定是否需要多个配置文件，以及如何组合它们以创建有效的过滤器。 多个配置文件可以并入到单个过滤器中，并且各个过滤器组合以创建整体过滤器。 然后可以将组合过滤器进一步组合以创建元过滤器。
