    • An anti-spam tool works with a web browser to detect spam webpages locally on a client machine. The anti-spam tool can be implemented either as a plug-in module or an integral part of the browser, and manifested as a toolbar. The tool can perform an anti-spam action whenever a webpage is accessed through the browser, and does not require direct involvement of a search engine. A spam detection module installed on the computing device determines whether a webpage being accessed or whether a link contained in the webpage being accessed is spam, by comparing the URL of the webpage or the link with a spam list. The spam list can be downloaded from a remote search engine server, stored locally and updated from time to time. A two-level indexing technique is also introduced to improve the efficiency of the anti-spam tool's use of the spam list.
    • 反垃圾邮件工具与网络浏览器配合使用,可以在客户机上本地检测垃圾邮件网页。 反垃圾邮件工具可以作为插件模块或浏览器的组成部分来实现,并且表现为工具栏。 每当通过浏览器访问网页时,该工具都可以执行反垃圾邮件操作,并且不需要直接参与搜索引擎。 安装在计算设备上的垃圾邮件检测模块通过将网页或链接的URL与垃圾邮件列表进行比较来确定正在访问的网页是否被访问的网页中包含的链接是垃圾邮件。 垃圾邮件列表可以从远程搜索引擎服务器下载,本地存储和不时更新。 还引入了两级索引技术,以提高反垃圾邮件工具使用垃圾邮件列表的效率。

    • A method and system for determining temporal importance of documents having links between documents based on a temporal analysis of the links is provided. A temporal ranking system collects link information or snapshots indicating the links between documents at various snapshot times. The temporal ranking system calculates a current temporal importance of a document by factoring in the current importance of the document derived from the current snapshot (i.e., with the latest snapshot time) and the historical importance of the document derived from the past snapshots. To calculate the current temporal importance of a web page, the temporal ranking system aggregates the importance of the web page for each snapshot.
    • 提供了一种用于基于链接的时间分析来确定具有文档之间的链接的文档的时间重要性的方法和系统。 时间排序系统收集指示各种快照时间的文档之间的链接的链接信息或快照。 时间排序系统通过考虑从当前快照(即,具有最新快照时间)导出的文档的当前重要性以及从过去快照导出的文档的历史重要性来计算文档的当前时间重要性。 为了计算网页的当前时间重要性,时间排序系统聚合每个快照的网页的重要性。
