摘要： A set of documents is filtered for entity extraction. A list of entity strings is received. A set of token sets that covers the entity strings in the list is determined. An inverted index generated on a first set of documents is queried using the set of token sets to determine a set of document identifiers for a subset of the documents in the first set. A second set of documents identified by the set of document identifiers is retrieved from the first set of documents. The second set of documents is filtered to include one or more documents of the second set that each includes a match with at least one entity string of the list of entity strings. Entity recognition may be performed on the filtered second set of documents.

摘要： Architecture for finding related entities for web search queries. An extraction component takes a document as input and outputs all the mentions (or occurrences) of named entities such as names of people, organizations, locations, and products in the document, as well as entity metadata. An indexing component takes a document identifier (docID) and the set of mentions of named entities and, stores and indexes the information for retrieval. A document-based search component takes a keyword query and returns the docIDs of the top documents matching with the query. A retrieval component takes a docID as input, accesses the information stored by the indexing component and returns the set of mentions of named entities in the document. This information is then passed to an entity scoring and thresholding component that computes an aggregate score of each entity and selects the entities to return to the user.
摘要翻译：用于查找网络搜索查询的相关实体的架构。提取组件将文档作为输入并输出所有实体的所有提及（或出现），例如文档中的人员，组织，位置和产品的名称以及实体元数据。索引组件采用文档标识符（docID）和命名实体的提及集合，并存储和索引信息进行检索。基于文档的搜索组件接受关键字查询，并返回与查询匹配的顶级文档的docID。检索组件将docID作为输入，访问由索引组件存储的信息，并返回文档中命名实体的提及集。然后将该信息传递给实体计分和阈值组件，该组件计算每个实体的聚合分数，并选择要返回给用户的实体。

摘要： This patent application relates to interval-based information retrieval (IR) search techniques for efficiently and correctly answering keyword search queries. In some embodiments, a range of information-containing blocks for a search query can be identified. Each of these blocks, and thus the range, can include document identifiers that identify individual corresponding documents that contain a term found in the search query. From the range, a subrange(s) having a smaller number of blocks than the range can be selected. This can be accomplished without decompressing the blocks by partitioning the range into intervals and evaluating the intervals. The smaller number of blocks in the subranges(s) can then be decompressed and processed to identify a doc ID(s) and thus document(s) that satisfies the query.
摘要翻译：该专利申请涉及用于有效和正确地回答关键词搜索查询的基于间隔的信息检索（IR）搜索技术。在一些实施例中，可以识别用于搜索查询的一系列含有信息的块。这些块中的每个以及因此的范围可以包括识别包含在搜索查询中找到的术语的各个对应文档的文档标识符。从该范围可以选择具有比该范围少的块数量的子范围。这可以在不通过将范围划分成间隔并且评估间隔来解压缩块的情况下实现。然后可以解压缩和处理子范围中较小数量的块，以识别文档ID，从而识别符合查询的文档。

摘要： This patent application relates to taxonomy editing. One implementation involves a taxonomy editor configured to generate a visual representation of a taxonomy associated with a set of scientific papers. The taxonomy editor includes a properties module configured to identify properties relating to an individual node of the taxonomy and a statistics module configured to determine trends relating to the individual node. The taxonomy editor further includes a similarity module configured to evaluate keyword similarity relative to individual scientific papers associated with the individual node. The taxonomy editor also includes a suggestion module configured to utilize the properties, the trends and the keyword similarity to identify potential modifications to the taxonomy. The taxonomy editor is further configured to present at least some of the potential modifications, the properties, the trends, and the keyword similarity concurrently with the visual representation of the taxonomy.
