The definition of plagiarism

K.U.Leuven defines plagiarism as follows:

Plagiarism is any identical or lightly-altered use of one's own or someone else’s work (ideas, texts, structures, images, plans, etc.) without adequate reference to the source.

Plagiarism appears in different forms:

  • The literal or near-literal use of someone else’s text(s) (or parts of these) irrespective of the source (including digital sources, whether or not through the internet) without indicating a citation (for example, through quotation marks) and / or without adequate reference to the source
  • Copying images, diagrams, graphics, figures, sound or image fragments, etc., without adequate reference to the source
  • Paraphrasing someone else’s arguments without adequate reference to the source
  • Translating texts without adequate reference to the source

Plagiarism damages the quality of a paper and thus can be interpreted as fraud. Other forms of fraud lean towards plagiarism and are just as intolerable, such as:

  • Commissioning or having papers revised (whether or not for pay), and passing this off as one’s own work
  • The re-use of one’s own work and passing it off as a new paper
  • Simulating or falsifying research data
