The system will do everything by itself and will show the final result with a list of copied sentences. Then click on the ‘check for plagiarism’ button. It is enough just to copy-paste the text within the particular field. In that case, Turnitin will identify this similarity and give it a score based on how much of the student’s work matches the original source. Suppose a student copied or paraphrased part of another source into their own essay.
The more extensive the similarities, the higher the similarity score will be.įurthermore, Turnitin uses a similarity detection engine that compares student work to other text sources. Turnitin will then return a list of documents that share these features with the submitted document and provide a similarity score based on the number and extent of those matches. These algorithms all operate on the same principle: comparing the features of a submitted document to all of the other documents in Turnitin’s databases. In addition, Turnitin uses a proprietary set of algorithms to perform its matching. Turnitin would consider paraphrasing plagiarism unless the author referenced it.īesides, it uses machine learning technologies to compare student submissions with an extensive database of other works (e.g., online content, student papers, and professional journal articles/books) in order to identify potential instances of plagiarism or paraphrasing. The algorithm checks for matching text and reviews if the author paraphrased the text. Turnitin uses algorithms such as those used by search engines to find matching phrases, sentences, and words. We can discover how Turnitin detects paraphrasing in the following section. If you have to do then let it be sparingly. However, if you are not careful, technology will catch you up. Such an activity includes using synonyms and breaking the sentence structure. It is an approach that helps one to integrate the same ideas in an essay. It is when the sentence structure or word choice changes. Paraphrasing implies that one is only rewriting similar information in a different way.
However, Turnitin can catch paraphrasing that does not reword a passage sufficiently. Paraphrasing is difficult for computers to detect because it involves changing both the words and the order of sentences in a passage, not just replacing synonyms.
