Examples of plagiarism and explanations


  1. The plagiarized sentence is repeated almost verbatim, in a copy-paste fashion. The addition of ‘the authors argue’ at the beginning isn’t enough, as what follows is a direct quote that ought to be within quotation marks. A citation should also have been added.Conversely, the non-plagiarized sentence is a complete rephrasing of the sentence and also includes a citation at the end.
  2. Similarly to the previous sentence, here the original sentence is entirely copied and pasted in the plagiarized version. The non-plagiarized version of the sentence addresses the problem in two ways: by rephrasing the original sentence, and acknowledging the source of the idea (‘According to Guo et al. (2022)’).
  3. Although a citation is added at the end, the sentence ‘It can be widely used in geological disaster warning and engineering construction projects in the future’ is reused word for word. To avoid plagiarism here, either quotation marks should have been added, or the sentence should have been paraphrased. The correct version solves the issue by adding quotation marks around the borrowed sentence.
  4. Here, the sentence has been successfully rewritten using the writer’s own words, but it is still plagiarism as the source of the idea isn’t acknowledged. Adding a citation at the end of the paraphrase solves the issue.
