DETECTING WEB SPAM FROM CHANGES TO LINKS OF WEB SITES

摘要

A method and system for determining whether a web site is a spam web site based on analysis of changes in link information over time is provided. A spam detection system collects link information for a web site at various times. The spam detection system extracts one or more features from the link information that relate to changes in the link information over time. The spam detection system then generates an indication of whether the web site is a spam web site using a classifier that has been trained to detect whether the extracted feature indicates that the web site is likely to be spam.
