Most Common Signs of Plagiarized Work

 
  • Papers written in a more sophisticated way that the student's previous work

  • Text format uncommon for regular word processing documents (i.e., similar to print out of web pages).

  • Paper seems to be made of independent pieces, some with different writing styles.

  • Different citation styles in the same paper.

  • The absence of current references and/or the presence of dead links. Both indicate what might be a very old document.

What to Do When You Suspect a Paper Has Been Plagiarized?


Although no magic recipe to identify cases of plagiarism exists, some strategies might help.  If you get a paper you suspect was plagiarized:

  • Talk to the writer of the paper. Ask about the procedure s/he used during the research process, where the sources were found and how, etc. Ask the student to clarify any point you believe was too advanced for him/her.

  • Compare the paper with those handed in by students of previous semesters;

  • Use search engines to compare the suspected paper with material on the Web;

  • Use a plagiarism detection service to compare the suspected paper with the Internet material and/or the company's database;

  • Use a "cloze test": Select part of the paper and delete every fifth word of the text. Then ask the writer of the paper to replace the missing words. The student might not be the author of the text if s/he cannot fill in over 80% of the words. This method is used by the Glatt plagiarism services.

Important: Note that to apply the suggestions above instructors will need to have access to the electronic versions of the papers. Thus, a good practice is always to require students to hand in both a hard copy and an electronic version of their papers. 

The above strategies for detecting plagiarism are detailed in the page, Anti-Plagiarism Tools, in this site.
