Van Eyk, E.D.C. (author), Van Leeuwen, W.J. (author)Crawljax is a crawler, which not only finds states via regular links, but also states that are hidden by JavaScript actions. However, this leads to a gigantic number of states with many duplicates. A near-duplicate detection algorithm can be a solution to limit the number of states found by Crawljax, while crawling the most essential, unique...bachelor thesis 2014
