Plagiarism Detection Tools


Plagiarism: The term plagiarism comes from the Latin word plagium meaning “kidnapping a man” (Masic, 2012). Plagiarism is the “literary theft” whose Bengali meaning is ‘Lekhachuri’ (Rahman, 2015). Plagiarism means taking the “words, thoughts, ideas, concepts, images, sentences and so forth” of others and using them as if they were your own, without crediting the author or citing the source (University of Kentucky, 2007). Copyright laws protect writers' words and idea as their legal property. Both plagiarisms of data and plagiarism of text are recognized in scientific writing (Plagiarism.org, 2017).

The followings are considered as plagiarism:

  1. Turning in someone else's work as his/her own;
  2. Copying words or ideas from someone else without giving credit;
  3. Failing to put a quotation in quotation marks;
  4. Giving incorrect information about the source of a quotation;
  5. Changing words but copying the sentence structure of a source without giving credit;
  6. Copying so many words or ideas from a source that it makes up the majority of the work, whether you give credit or not (eliteracysociety.org, 2015);
  7. Mentioning own research result or idea (self-plagiarism) of his/her another publication; and
  8. Even translating from other languages (Rahman, 2015).

Criteria for detecting plagiarism
According to the World Association of Medical Editors (WAME):
  1. Sequentially 6 words; or
  2. 7-11 words of a set of 30 words.

How to avoid plagiarism
  1. Quotation Mark: Using Quotation Mark and proper citation.
  2. Paraphrasing: A paraphrase is a restatement of the meaning of a text or passage using other words. But we must not avoid citing the source.
