StrikePlagiarism is a Polish system that we have tested twice before. They had improved their overall effectiveness in the 2008 test, but have now dropped to just 52%. They had similar problems to Copyscape, not flagging plagiarisms they found in 2008, and reporting plagiarism in original papers that they had not previously reported. On the English-language new test cases they did, however, reach 5th place. The usability was, however, again problematic. The page loads extremely slowly; we could not find a way to upload a PDF; a title and an author had to be entered by hand for every paper uploaded; there were pages that had English, German, and Polish on them, the language would change at times without notice; horizontal scrolling was necessary; we still do not understand what the difference in the coefficients is; once it finds a source (Wikipedia!) with 7 words matching, it does not seem to try and extend the matching, thus reporting only a small amount of plagiarism in a 100% copy of the Wikipedia. We were, however, able to reach someone who was able to speak English with us on the phone.
