摘要： Ranking documents based on a series of web graphs collected over time is provided. A ranking system provides multiple transition probability distributions representing different snapshots or times. Each transition probability distribution represents a probability of transitioning from one document to another document within a collection of documents using a link of the document. The ranking system determines a stationary probability distribution for each snapshot based on the transition probability distributions for that snapshot and the stationary probability distribution of the previous snapshot. The stationary probability distributions represent a ranking of the documents over time.
摘要翻译：提供了基于随时间收集的一系列网络图表排列文档。排名系统提供代表不同快照或时间的多个转移概率分布。每个转移概率分布表示使用文档的链接在一个文档集合内从一个文档转换到另一个文档的概率。排名系统基于该快照的转移概率分布和先前快照的固定概率分布确定每个快照的固定概率分布。固定概率分布代表文档随时间的排列。

摘要： 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.
摘要翻译：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。

摘要： A calculate importance system calculates the global importance of a web page based on a “mean hitting time.” Hitting time of a target web page is a measure of the minimum number of transitions needed to land on the target web page. Mean hitting time of a target web page is an average number of such transitions for all possible starting web pages. The calculate importance system calculates a global importance score for a web page based on the reciprocal of a mean hitting time. A search engine may rank web pages of a search result based on a combination of relevance of the web pages to the search request and global importance of the web pages based on a global hitting time.

摘要： 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.
