I have been super busy lately, as we are testing as many plagiarism detection software systems as we can get our fingers on. The final results will be announced on September 27, 2007 at 12.00 UTC+1, so if you are considering obtaining such a system, you might want to wait a few weeks.
We looked at 15 plagiarism detection systems, one collusion detection system and two code sharing detection systems. We used 20 short papers of known plagiarism degree, two files for collusion detection and two 400-line program code files specifically prepared with 14 different types of "masking" behavior.
Stay tuned for the results - in German first, I'm afraid, but we will get around to putting it in English soon, I hope!
