    • Mining geographic knowledge using a location aware topic model is provided. A location system estimates topics and locations associated with documents based on a location aware topic (“LAT”) model. The location system generates the model from a collection of documents that are labeled with their associated locations. The location system generates collection level parameters based on an LDA-style model. To generate the collection level parameters, the location system estimates probabilities of latent topics, locations, and words of the collection. After the model is generated, the location system uses the collection level parameters to estimate probabilities of topics and locations being associated with target documents.
    • 提供使用位置感知主题模型挖掘地理知识。 位置系统基于位置感知主题(“LAT”)模型估计与文档相关联的主题和位置。 位置系统从标有其关联位置的文档集合生成模型。 位置系统基于LDA样式模型生成收集级别参数。 为了生成收集级参数,定位系统估计集合的潜在主题,位置和单词的概率。 在模型生成之后,位置系统使用集合级参数来估计与目标文档相关联的主题和位置的概率。

    • A table system includes a classification system and a display system. The classification system trains a classifier to classify tables of display pages as a data table or not a data table based on certain features of the tables. The display system identifies the tables of a display page, identifies the features of the tables, and then uses the classifier to classify the tables based on their features. When a table is not classified as a data table, the display system may display the table in a conventional one-column view. When a table is classified as a data table, the display system displays the data table in an alternate view that attempts to preserve the layout and thus meaning of the data table.
    • 表系统包括分类系统和显示系统。 分类系统训练一个分类器,将显示页面的表格分类为数据表,或者基于表的某些特征将数据表分类。 显示系统识别显示页面的表,标识表的特征,然后使用分类器根据其特征对表进行分类。 当表不被分类为数据表时,显示系统可以以传统的一列视图显示该表。 当表被分类为数据表时,显示系统将在替代视图中显示数据表,尝试保留数据表的布局和意义。

    • Determination of a target category associated with a business listings query is provided. A query categorization system initially generates a mapping of internal categories of the query categorization system to target categories of a search engine service. The query categorization system receives a business listings query and identifies business listings that match the query. The query categorization system identifies an internal category associated with each matching business listing. The query categorization system then identifies from the mapping the target categories that correspond to the identified internal categories. The query categorization system selects one of the identified target categories as the category to be associated with the query.
    • 提供与业务列表查询相关联的目标类别的确定。 查询分类系统最初生成查询分类系统的内部类别到搜索引擎服务的目标类别的映射。 查询分类系统接收业务列表查询并识别与查询匹配的业务列表。 查询分类系统识别与每个匹配的业务列表相关联的内部类别。 然后,查询分类系统从映射中识别与所识别的内部类别相对应的目标类别。 查询分类系统将所识别的目标类别之一选择为与查询相关联的类别。
