    • Methods, systems, and apparatus, including computer program products, for generating synthetic queries using seed queries and structural similarity between documents are described. In one aspect, a method includes identifying embedded coding fragments (e.g., HTML tag) from a structured document and a seed query; generating one or more query templates, each query template corresponding to at least one coding fragment, the query template including a generative rule to be used in generating candidate synthetic queries; generating the candidate synthetic queries by applying the query templates to other documents that are hosted on the same web site as the document; identifying terms that match structure of the query templates as candidate synthetic queries; measuring a performance for each of the candidate synthetic queries; and designating as synthetic queries the candidate synthetic queries that have performance measurements exceeding a performance threshold.
    • 描述了使用种子查询和文档之间的结构相似性来生成合成查询的方法,系统和装置,包括计算机程序产品。 一方面,一种方法包括从结构化文档和种子查询中识别嵌入的编码片段(例如HTML标签); 生成一个或多个查询模板,每个查询模板对应于至少一个编码片段,所述查询模板包括要用于生成候选综合查询的生成规则; 通过将查询模板应用于与文档在同一网站上托管的其他文档来生成候选综合查询; 将与查询模板的结构匹配的条款识别为候选综合查询; 测量每个候选综合查询的性能; 并且将具有超过性能阈值的性能测量的候选综合查询指定为合成查询。
