    • A method and system are provided removing systematic bias from property value predictions obtained using automated property valuation models. The systematic bias is removed by deriving monthly adjustment factors that are location-specific. The monthly adjustment factors are obtained by comparing newly obtained purchase transaction data to model-generated valuations of properties in a base valuation database. The newly obtained purchase transactions may be obtained from newly obtained data on recently completed purchase transactions and loan application data on future purchase transactions. The monthly adjustment factors are applied to the property valuations in the base valuation database to obtain adjusted property values having reduced bias and thus improved accuracy.
    • 提供了一种方法和系统,从使用自动化物业估值模型获得的财产价值预测中消除系统偏差。 通过推导出具体位置的月度调整因子来消除系统偏差。 通过将新获得的购买交易数据与基准估价数据库中的属性的模型生成估值进行比较,可以获得月度调整因子。 新获得的购买交易可以从最近获得的关于最近完成的购买交易的数据和关于未来购买交易的贷款申请数据获得。 月度调整因子适用于基准估值数据库中的物业估值,以获得偏差偏小的调整后的财产值,从而提高准确性。

    • Systems and methods for extracting data content items from a web page are provided. A template is created by labeling data content items of interest associated with a web page and generating a template Document Object Model (DOM) tree based on the labeled web page. DOM trees are also generated for additional web pages that contain data content items for which extraction may be desired. These DOM trees are compared to the template DOM tree to determine alignment there between. The aligned data content items may then be extracted from the additional web pages and indexed, as desired. Labeling the data content items of interest prior to generating a template DOM tree allows for the desired data content items to be specified and more accurately extracted from related and/or similarly structured web pages.
    • 提供了从网页提取数据内容项目的系统和方法。 通过标记与网页相关联的感兴趣的数据内容项目并基于标记的网页生成模板文档对象模型(DOM)树来创建模板。 还为包含可能需要提取的数据内容项的附加网页生成DOM树。 将这些DOM树与模板DOM树进行比较,以确定其间的对齐方式。 然后,可以根据需要从附加网页中提取对准的数据内容项并进行索引。 在生成模板DOM树之前标注感兴趣的数据内容项允许从相关和/或类似结构化的网页更精确地提取期望的数据内容项目。

    • The present invention relates to a method for fast locating records on a data page in a database, comprising the steps of: setting a directory structure composed of a group of record deviations at the end of a data page, in which, a record deviation is a position deviation of a record on the data page; each directory in the directory structure is called dir_slot, and each dir_slot stores the position deviation of one record; searching for relative records in the dir_slot by adopting a dichotomizing locating algorithm, after locating one certain dir_slot, searching the relative group of records in order according to the record deviation stored in the dir_slot and locating the record to be searched for accurately. The present invention greatly improves the speed of locating a record on a page, saves large amount of costs for sequential search, largely reduces times of searching and comparing, and manages the records on the pages effectively.
    • 本发明涉及一种用于在数据库中的数据页面上快速定位记录的方法,包括以下步骤:在数据页的末尾设置由一组记录偏差组成的目录结构,其中记录偏差为 数据页上记录的位置偏差; 目录结构中的每个目录称为dir_slot,每个dir_slot存储一个记录的位置偏差; 通过采用二分法定位算法,在定位一个dir_slot之后,根据存储在dir_slot中的记录偏差依次搜索相对记录组,并准确定位要搜索的记录,在dir_slot中搜索相对记录。 本发明大大提高了页面上记录的定位速度,节省了大量的连续搜索成本,大大减少了搜索和比较的时间,有效地管理页面上的记录。
