演讲摘要：

The Web contains billions of interconnected web pages. It can thus form a large-scale graph with web pages as nodes and links as edges. Link analysis on the large-scale graph is useful for many Web applications like page importance computation and index selection.

Spam has become one of the biggest challenges for web search engines. Many anti-spam technologies have been developed to automatically detect web spam and eliminate related spam sites from search results. These technologies can accurately identify spam by analyzing the content and topological structure of the Web, utilizing temporal information of the web, and mining from behavior data of Web users.
