A WebmasterWorld thread links to a December 2006 paper at Yahoo! Research named A Reference Collection for Web Spam. The paper can be downloaded as a PDF file, it is not brand new, but relatively new. Here is the abstract:
We describe the WEBSPAM-UK2006 collection, a large set of Web pages that have been manually annotated with labels indicating if the hosts are include Web spam aspects or not. This is the first publicly available Web spam collection that includes page contents and links, and that has been labeled by a large and diverse set of judges.
Gary Price of ResourceShelf linked to an updated paper from Microsoft on Web spam. The 10 page PDF file is named "Spam Double-Funnel: Connecting Web Spammers with Advertisers." Here is the abstract:
Spammers use questionable search engine optimization (SEO) techniques to promote their spam links into top search results. In this paper, we focus on one prevalent type of spam – redirection spam – where one can identify spam pages by the third-party domains that these pages redirect traffic to. We propose a five-layer, double-funnel model for describing end-to-end redirection spam, present a methodology for analyzing the layers, and identify prominent domains on each layer using two sets of commercial keywords – one targeting spammers and the other targeting advertisers. The methodology and findings are useful for search engines to strengthen their ranking algorithms against spam, for legitimate website owners to locate and remove spam doorway pages, and for legitimate advertisers to identify unscrupulous syndicators who serve ads on spam pages.
So here is your weekend reading.
