    • Systems and methods for automating digital file classification are described. The systems and methods include generating a plurality of classifiers from a plurality of first features of a plurality of first digital files, each of the plurality of first digital files having one or more associated annotations. A plurality of second features extracted from a plurality of second digital files is sorted according to the plurality of classifiers. A distance vector is determined between the second features and respective first features for the corresponding ones of the classifiers and the determined distances are ranked. A subset of matched files is selected based on the ranking. The subset of matched files correspond to respective one or more associated annotations. One or more annotations associated with the subset of matched files are associated to subsequently received digital files using the corresponding ones of the classifiers.
    • 描述用于自动化数字文件分类的系统和方法。 所述系统和方法包括从多个第一数字文件的多个第一特征生成多个分类器,所述多个第一数字文件中的每一个具有一个或多个相关联的注释。 根据多个分类器对从多个第二数字文件提取的多个第二特征进行分类。 在第二特征和对应的分类器的相应第一特征之间确定距离矢量,并且对所确定的距离进行排序。 基于排名选择匹配文件的子集。 匹配文件的子集对应于相应的一个或多个相关注释。 与匹配文件的子集相关联的一个或多个注释与随后接收的数字文件相关联,使用相应的分类器。

    • A search system generates a plurality of pseudo-documents for a set of documents. Each pseudo-document includes a representation one or more documents from the set of documents that would be retrieved in response to executing a respective basis query over the set of documents. The search system generates an index of the plurality of pseudo-documents. The index provides an indication, for a plurality of respective documents from the set of documents, of the pseudo-documents that include a representation of the respective document. After generating the index, the search system receives a document-query that includes a representation of a first document; and in response to receiving the document-query, the search system identifies one or more pseudo-documents that include representations of at least one document having a predefined relationship to the first document; and generates a result that is based on the first set of one or more pseudo-documents.
    • 搜索系统为一组文档生成多个伪文档。 每个伪文档包括表示来自文档集合中的一个或多个文档,该文档将响应于在该组文件上执行相应的基本查询而被检索。 搜索系统生成多个伪文档的索引。 索引为来自文档集合的多个相应文档提供包括相应文档的表示的伪文档的指示。 在生成索引之后,搜索系统接收包括第一文档的表示的文档查询; 并且响应于接收到所述文档查询,所述搜索系统识别包括至少一个与所述第一文档具有预定关系的文档的表示的一个或多个伪文档; 并生成基于第一组一个或多个伪文档的结果。
