Spam blogs (splogs) have become a major problem in the increasingly popular blogosphere. Splogs are detrimental in that they corrupt the quality of information retrieved and they waste tremendous network and storage resources. We study several research issues in splog detection. First, in comparison to web spam and email spam, we identify some unique characteristics of splog. Second, we propose a new online task that captures the unique characteristics of splog, in addition to tasks based on the traditional IR evaluation framework. The new task introduces a novel time-sensitive detection evaluation to indicate how quickly a detector can identify splogs. Third, we propose a splog detection algorithm that combines traditional content features with temporal and link features that are unique to blogs. Finally, we develop an annotation tool to generate ground truth on a sampled subset of the TREC-Blog dataset. Initial experiments based on this ground truth set show promising results. 1.
