    Abstract

    Web spam has been recognized as one of the top challenges in the search engine industry [14]. A lot of recent work has addressed the problem of detecting or demoting web spam, in-cluding both content spam [16, 12] and link spam [22, 13].However, any time an anti-spam technique is developed, spam-mers will design new spamming techniques to confuse search engine ranking methods and spam detection mechanisms. Ma-chine learning-based classification methods can quickly adapt to newly developed spam techniques. We describe a two-stage approach to improve the performance of common classifiers. We first implement a classifer to catch a large portion of spam in our data. Then we design several heuristics to decide if a node should be relabeled based on the preclassifed result and knowledge about the neighborhood. Our experimental results show visible improvements with respect to precision and recall.
