    • An optimizer/normalizer is used to generate optimized intermediate language representation of an input query, such as an XML input query. A method of optimization of an input query in intermediate language form includes receiving the input query, examining the nodes in a left-depth first manner to identify code patterns and node types which are subjects for optimization, tagging the identified code patterns until the intermediate language representation of the input query has been examined in its entirety, searching from the top of the intermediate language representation for tagged code patterns, and adjusting the tagged code patterns with improved code patterns to form an optimal representation for an input query. The input to the optimizer/normalizer is assumed to be an input query transformed into an intermediate language representation containing code patterns and nodes, each node having a respective node type.
    • 优化器/规范化器用于生成输入查询的优化中间语言表示,例如XML输入查询。 以中间语言形式优化输入查询的方法包括接收输入查询,以左深度第一方式检查节点以识别作为优化对象的代码模式和节点类型,标记所识别的代码模式,直到中间语言 已经对输入查询的表示进行了全面的检查,从标记代码模式的中间语言表示的顶部进行搜索,并且利用改进的代码模式调整带标签的代码模式以形成用于输入查询的最佳表示。 假设优化器/规范化器的输入是被转换成包含代码模式和节点的中间语言表示的输入查询,每个节点具有相应的节点类型。

    • A server system is disclosed that is capable of providing responsive content to a user when a request for an invalid URL is received. In a preferred embodiment, the server system implements multiple rescue strategies for attempting to rescue the invalid URL. One such rescue strategy involves repairing the URL by correcting for encoding errors, such as errors introduced by some web clients. Another rescue strategy involves determining that the URL contains an obsolete or outdated item identifier (e.g., product identifier) that renders the URL invalid, and returning information regarding one or more related items to the user. Another rescue strategy involves mining the invalid URL for one or more text strings reflective of the type of content desired, and then using the one or more text strings to execute a keyword search to identify content to provide to the user. The various rescue strategies may be attempted in sequence according to a hierarchy.
    • 公开了当接收到对无效URL的请求时能够向用户提供响应内容的服务器系统。 在优选实施例中,服务器系统实施用于尝试拯救无效URL的多种营救策略。 一种这样的救援策略涉及通过纠正编码错误(例如某些网络客户端引入的错误)​​来修复URL。 另一个救援策略涉及确定URL包含呈现URL无效的过时或过时的项目标识符(例如,产品标识符),以及将关于一个或多个相关项目的信息返回给用户。 另一个救援策略涉及对反映所需内容类型的一个或多个文本串挖掘无效URL,然后使用一个或多个文本字符串来执行关键词搜索以识别要提供给用户的内容。 可以按照层次结构来顺序地尝试各种救援策略。
