Last week I tweeted about about "Five Ways to Defeat Automated Plagiarism Detection" and have got some reaction about this from both inside and outside the College. One of the ways was to use a translator to change original text from one language to another. Taking this a step further I decided to conduct a small experiment and use Google Translate to translate some text from English to Spanish, then to French, Polish, Chinese, and back to English. The results are in brown and italic text below.
The sentence I chose was from Wikipedia - I copied word-for-word the first paragraph (removing the hyperlinks) of the Wikipedia page about US President Abraham Lincoln. After the translations had been done, I submitted all the text in all languages to Turnitin. Turnitin correctly detected that the first (original) paragraph was copied from Wikipedia. Interestingly, only a short piece of the Spanish version, and NONE of the French, Polish, or Chinese versions was detected as being similar to anything else. The final paragraph, in English is of course not the same as the original after being translated five times. Here's the before and after Turnitin report:
Before Translation:
After Translation:
As you can see, the translations has had an effect, but not enough in this example to clear a paper of plagiarism. If this second example was presented to me in an assignment it would be referred to the Plagiarism/Discipline Committees. If you are a student reading this post to learn how to beat tools like Turnitin, I'm afraid to tell you that you are running a very high risk of still being caught. Turnitin has done a good job in detecting cheating like this. The message is: DON'T DO IT - YOU WILL BE CAUGHT!
