Test of Plagiarism Detection Software

It's finished, it's published. We worked feverishly right up to the wire. On Sept. 26 we sent copies of the preliminary reports (they were still in line for some language polishing) to the companies tested, so that they could prepare a statement, if they so chose.

We held a press conference this afternoon, cutting over to the new version of the plagiarism portal and the E-Learning unit on plagiarism detection ("Fremde Federn Finden", in German) at the start of the conference. We had 5 reporters in attendance and many who requested virtual press materials. The online magazine "Spiegel Online" had requested that we write a summary article for them, so we just cut out sleep for a few days in order to get it done.

We have had a lot of interest from reports and of course the companies tested. If we learn of other systems, we will be glad to test them as we have time (which will be spare time, as the financing for this project runs out tomorrow), although the results might not be comparable, as the Internet is constantly changing.

Here is a copy of the ranking page:

Ranking

Excellent Systems

No system was ranked as excellent - but there have been many people who attended plagiarism detection seminars who scored 100% on the same tests!

Good Systems

Nr. 1 : Ephorus

Acceptable Systems

Nr. 2 : Docoloc
Nr. 3 : Urkund, Copyscape (premium), PlagAware
Nr. 6 : Copyscape (free)
Nr. 7 : TextGuard
Nr. 8 : turnitin, ArticleChecker
Nr. 10 : picapica

Unacceptable Systems

Nr. 11 : DocCop
Nr. 12 : iPlagiarismCheck, StrikePlagiarism
Nr. 14 : CatchItFirst

We hope that our work can help these companies to produce better results. But our summary for 2007 is the same as for 2004: It is better to use a search machine yourself, the software just costs money and is not necessarily very good at finding all plagiarisms.

  1. I just realized that I never commented directly to this piece, obviously I am now subject to some kind of horrible punishment.

    Still, I wanted to say great work on this project! The results are great and, I think, fairly useful.

    No test will be definitive in this area, but at least I now have a place to start as yours comes as close as possible.

  2. I've just came across this product:
    Plagiarism-Detector here -
    www.plagiarism-detector.com
    I wish you had ranked it as well.
    It produces really stunning results!
