    • Methods of constructing a document index including named entity information generated by at least one tool associated with parsing computer programs are presented. The methods include using a lexical analyzer generator, e.g. Flex, and/or a parser generator, e.g. Yacc, to generate named entity recognizers. The named entity recognizers are used to identify named entities in documents, in particular, very large document sets such as web pages available on the Internet. The identified named entities are stored as named entity annotations in the document index. Also, methods of performing searches using the document index are presented. The searches are performed based on queries that can be received on an application programming interface (API). Relevant documents are obtained using the named entity annotations, which can be returned across the API. Also presented are associated computer readable media.
    • 提出了构建包括由与解析计算机程序相关联的至少一个工具生成的命名实体信息的文档索引的方法。 这些方法包括使用词法分析器生成器,例如, Flex,和/或解析器生成器,例如。 Yacc,以生成命名实体识别器。 命名实体识别器用于识别文档中的命名实体,特别是非常大的文档集,如Internet上可用的网页。 识别的命名实体作为命名实体注释存储在文档索引中。 此外,呈现使用文档索引执行搜索的方法。 搜索是基于可以在应用程序编程接口(API)上接收的查询来执行的。 使用命名实体注释获取相关文档,可以通过API返回。 还提供了相关联的计算机可读介质。
