In this paper the authors is concerned with mining link spams (e.g., link farm and link exchange) from Search Engine Optimization (SEO) forums. To provide quality services, it is critical for search engines to address web spam. Several techniques such as TrustRank, BadRank, and SpamRank have been proposed for this purpose.
