Contract cheating

Contract cheating involves getting other people to complete part or all of your work and then submitting the work as if you had completed it yourself.

The aim of contract cheating detection technology is to find inconsistencies in the writing style of the author. The contract cheating detection is based on stylometry – a statistical method created to analyze style in order to determine authorship.

Certainly, the plagiarism, and dealing with the fallout of it, was the most difficult thing I've ever faced since I started writing.

Some Facts About Plagiarism

Roughly one out of three students plagiarise and have admitted to doing so. If we count in the human factor of not recognising the fact that they have plagiarised something, the number is going to be higher. Some estimates claim that it is closer to 50 or even 60%.

The most prominent source of plagiarised content is the internet (~90%).

Around 80 to 85% of the students who admitted to plagiarism claimed that they were not caught or have not received any punishment.

Almost all the students who admit to plagiarism (~95%) knew that they did something wrong. This shows awareness and indicates that the choice to plagiarise content or copy work was the last resort or a result of troubling circumstances.

Close to 65% – cheated on a test by copying notes or someone else’s answers.

Around 60% – claimed that plagiarised content made up a significant part of at least one of their assignments.

Almost 97% – agreed to the fact that they plagiarised or copied homework answers, answers on a test or cheated.

Only 16% – admitted that they were caught doing so or after doing so and were punished. Most punishments, however, were nullified tasks or requests to rewrite. Less than 1% of the students received severe penalties like suspension or got expelled.

Even though there is no official data, some smaller surveys and researches state that plagiarism numbers increased about 10% over the past 16 years.
