    • A phrase identification system and method are provided. The method comprises: identifying one or more phrase candidates in the electronic document; selecting one of the phrase candidates; numerically representing features of the selected phrase candidates to obtain a numeric feature representation associated with that phrase candidate; and inputting the numeric feature representation into a machine learning classifier, the machine learning classifier being configured to determine, based on each numeric feature representation, whether the phrase candidate associated with that numeric feature representation is a phrase.
    • 提供短语识别系统和方法。 该方法包括:识别电子文档中的一个或多个短语候选者; 选择短语候选人之一; 数字地表示所选择的短语候选的特征以获得与该短语候选相关联的数字特征表示; 以及将所述数字特征表示输入到机器学习分类器中,所述机器学习分类器被配置为基于每个数字特征表示来确定与所述数字特征表示相关联的短语候选是短语。

    • A system and method for crawling Web content. First a set of geographic locations is defined. A portion of the set of geographic locations is assigned to a first crawling node. A second portion of the set of geographic locations is assigned to as second crawling node. The first and second crawling nodes then crawl Web content. For each Web page that is located by the first and second crawling nodes a determination is made as to whether the Web page contains a geographic location that belongs the set of geographic locations. If it is determined that the a Web page that is located by either the first or second crawling node does belong to the set of geographic locations, then that Web page is referred to the crawling node to which that geographic location is assigned.
    • 一种用于抓取Web内容的系统和方法。 首先定义一组地理位置。 一组地理位置的一部分被分配给第一爬行节点。 该组地理位置的第二部分被分配为第二爬行节点。 第一个和第二个抓取节点然后抓取Web内容。 对于由第一和第二爬行节点定位的每个网页,确定网页是否包含属于该地理位置集合的地理位置。 如果确定由第一或第二爬行节点定位的网页属于该地理位置集合,则该网页被引用到分配了该地理位置的爬网节点。

    • A voltage regulator includes a voltage generation unit, a first resistor section, and a second resistor section. The voltage generation unit compares a reference voltage level with a voltage level of a first node and generates an output voltage. The first resistor section includes a first sub-resistor and a second sub-resistor between the first node and a ground voltage node, and controls a connection between the first sub-resistor and the second sub-resistor to change a resistance value of the resistors. The second resistor section includes a reference resistor, a plurality of unit resistors, and a plurality of step resistors, and controls connections of the unit resistors and the step resistors to change a resistance value of the resistors.
    • 电压调节器包括电压产生单元,第一电阻器部分和第二电阻器部分。 电压产生单元将参考电压电平与第一节点的电压电平进行比较,并产生输出电压。 第一电阻器部分包括在第一节点和接地电压节点之间的第一子电阻器和第二子电阻器,并且控制第一子电阻器和第二子电阻器之间的连接以改变电阻器的电阻值 。 第二电阻器部分包括参考电阻器,多个单位电阻器和多个阶梯电阻器,并且控制单元电阻器和阶梯电阻器的连接以改变电阻器的电阻值。
