Einst lebte eine Dohle, voll von eitlem Stolz, die stahl sich Federn, die dem Pfau entfallen warn und putzte sich damit. Das eigne Dohlenvolk ver- achtend trat sie in der schönen Pfauen Reihn. Der Unver- schämten reißt man hier die Federn aus, jagt sie mit Schnäbeln. Und die Dohle, bös verbleit will wieder nun betrübt zu ihrem Volk zurück. Die aber stoßen sie von sich, mit herbem Schimpf. Und eine derer, die zuvor verachtet, sprach zu ihr “Hätt’ unsre Lebensart dir vormals conveniert, hätt’st du, was die Natur dir schenkte, akzeptiert, dann wär dir weder jene Schande widerfahrn noch müsstest du zum Unglück jetzt verstoßen sein.”

Diese Version von Aesops Fabel ist aus Wilfried Strohs Sammlung von Übersetzungen von Jan Novák: “Aesopia”, die auf Geschichten von Phaedrus basieren.

Plagiarisma is said to have been developed by Eugene Ekimov in 2010, but there is no company named and no contact information given. It splits up into an online-, Android- and desktop-Version. In each of these alternatives, a free and a premium version exists, although it is not clear how much the premium version costs and what one obtains for the price. The search is said to be based on five different search engines, which can be chosen by the user: Google, Yahoo, Babylon, Google Scholar or Google Books. Google Search is only enabled for registered users. In the 2012 test, only the desktop and the online version was tested. Plagiarisma also offers students a so-called „synonymizer“ that will replace words with synonyms in order to fool plagiarism detection systems.

Pros & Cons

The system states, that it can find plagiarism in 190 different languages. Files can be uploaded in all popular formats. In the current test, the system was able to find plagiarism in Hebrew language and also did find sources from Google Books. However, only five documents can be checked per IP address per day. This is probably due to the search engines that restrict the number of request per IP address. Plagiarisma suggests that customers misuse Tor, a system that supports anonymous browsing, in order to have multiple IP addresses from which to submit documents.

The results produced by Plagiarisma are not precise, often returning quite irrelevant sources. They system does not return a direct link to a source, but to the search engine results page for the sample of text used.  A manual followup for all of the links that are reported is thus necessary, so one might as well do the searching without the software. Additionally, many error messages appear that disturb the usage of the system.

In addition to the plagiarism search, Plagiarisma offers a Synonymizer which replaces words from a text with words from a Thesaurus which have equal meanings.


Desktop Version:

While the software was installed, it informed us about “known issues”. These include problems with the processing of Cyrillic letters in ODT-Format.

In the desktop version, which was tested on a Windows 7 operating system, file upload was not possible at all because the program immediately crashed when trying to upload a file. Because of that, the texts had to be copied into the text area given.

After copying the text, it took a long time for the system to process the report. While processing, the program does not respond. When it is finished, a report in HTML format is produced which tends to contain either broken links or links to the results using the chosen search engine.


One major problems with the online version  is that texts that contain more than 5000 characters are split up into multiple files and can only be checked with the Bing search engine. This limits the usage of Plagiarisma, especially for educational usage. Another problem that raises questions of the seriousness of the system is that Babylon search is used as the default. This search engine immediately proceeds to install the Babylon Toolbar without asking for permission. This toolbar has been categorized as a browser hijack (http://www.im-infected.com/hijacker/babylon-search-hijacker.html).

As the test was started, it was recognized that the upload function does not work properly. The system crashes many times while trying to upload a file and error messages were shown.

The free version of  Plagiarisma works with search by Yahoo or Bing, whereas only premium users get the possibility to chose other search engines. It is confusing that (compared to all other systems) non-plagiarized sentences are marked in a different color. This might be a problem for professors who are not digging deeper into the report because they might think that all the marked phrases are plagiarized which will lead to unjustified accuses. It is also not clear, where the plagiarized fragments are from because the tool is only linking to the results of the search engine. Another confusing discovery was that the system gives different results for the desktop and online version.


The Usability of Plagiarisma is categorized as not user friendly, because the System does not make clear for the user where functions can be found. Bugs and errors are additionally interfering the usage and making the system not usable for academic work.


In general, Plagiarisma is taking too much time for appropriate usage in educational institutions. The dubios search engine Babylon makes the system even more critical as well as the fact that it was found out that the two versions are returning different results in this test. The user can easily do the work the system does on his own by copying three to five words from a paragraph into a search engine and check the results. This makes the system more or less senseless.
