    • A method and system are provided for selecting advertisements for presentation to a user in response to a user search query. The system may include a keyword server for parsing the user search query and an index server for receiving the parsed search query. The index server may include an index of advertising phrases and pre-filtering components for comparing index entries to the parsed user search query in order to discard non-matching index entries and locate matching entries. The pre-filtering components may include either a phrase length pre-filtering component or a word hash pre-filtering component. The system may additionally include a listing server for sorting through the matching entries located by the index server and further filtering the matching entries for retrieval and presentation to the user.
    • 提供了一种方法和系统,用于响应于用户搜索查询来选择用于呈现给用户的广告。 系统可以包括用于解析用户搜索查询的关键字服务器和用于接收解析的搜索查询的索引服务器。 索引服务器可以包括广告短语的索引和用于将索引条目与解析的用户搜索查询进行比较的预过滤组件,以便丢弃不匹配的索引条目并定位匹配条目。 预过滤组件可以包括短语长度预过滤组件或字哈希预过滤组件。 该系统可以另外包括列表服务器,用于通过由索引服务器定位的匹配条目进行排序,并进一步过滤用于检索和呈现给用户的匹配条目。

    • A system and method for location-specific searching. The invention correctly identifies explicit and implicit locations in a search query, and provides an appropriate dominant location. Top search results are obtained and analyzed to determine which terms in the query often appear in combination, and the query is tokenized based on the analysis. An explicit location indicating a location intent is most likely treated as an individual token, and the explicit location is treated as the dominant location of the query. In the case of a false positive, wherein the explicit location in a query is not the location intent, the explicit location is likely to be present with other terms that provide context. A token will likely include these terms together. The explicit location will therefore not be used to generate location-specific results in the case of a false positive.
    • 用于位置特定搜索的系统和方法。 本发明正确地识别搜索查询中的显式和隐含位置,并提供适当的优势位置。 获取和分析热门搜索结果以确定查询中的哪些术语经常出现在组合中,并且基于分析对查询进行标记化。 指示位置意图的显式位置很可能被视为单独的令牌,并且显式位置被视为查询的主要位置。 在假阳性的情况下,其中查询中的显式位置不是位置意图,所以显式位置可能存在于提供上下文的其他项。 令牌可能会一起包含这些术语。 因此,在假阳性的情况下,显式位置不会用于生成位置特定的结果。
