R-SpamRank: A Spam Detection Algorithm Based on Link Analysis
نویسندگان
چکیده
Spam web pages intend to achieve higher-than-deserved ranking by various techniques. While human experts could easily identify spam web pages, the manual evaluating process of a large number of pages is still time consuming and cost consuming. To assist manual evaluation, we propose an algorithm to assign spam values to web pages and semi-automatically select potential spam web pages. We first manually select a small set of spam pages as seeds. Then, based on the link structure of the web, the initial R-SpamRank values assigned to the seed pages propagate through links and distribute among the whole web page set. After sorting the pages according to their R-SpamRank values, the pages with high values are selected. Our experiments and analyses show that the algorithm is highly successful in identifying spam pages, which gains a precision of 99.1% in the top 10,000 web pages with the highest R-SpamRank values.

SpamRank -- Fully Automatic Link Spam Detection
Spammers intend to increase the PageRank of certain spam pages by creating a large number of links pointing to them. We propose a novel method based on the concept of personalized PageRank that detects pages with an undeserved high PageRank value without the need of any kind of white or blacklists or other means of human intervention. We assume that spammed pages have a biased distribution of p...
