Detecting Plagiarism -
Resources for CBU Faculty


Clues to Look for:
(Based on Robert Harris's Anti-Plagiarism Strategies)

Keep an eye out for jargon or advanced vocabulary that seems out of place. Especially if your student is taking an entry-level class, they are not likely to be fluent in the jargon of the field.

On the other hand, beware of papers that appear to be of grade school quality. Students are not picky about what they cut and paste off the web - they can copy a seventh grade paper just as easily as a college term paper.

Look for anachronisms, such as references to the formation of NATO in the future tense, or comments about the present state of the Clinton administration.

Works Cited pages and Bibliographies can be invaluable in recognizing plagiarism:

Look for bibliographies that intermix citation styles. If a student uses MLA style, APA style, and Turabian all on one paper, chances are good that he copied these sources from another bibliography.

Another clue: the citations are all dated. If none of the citations date past 1994 on a topic where research has continued to progress, then the paper was probably written in 1994, not by your student.

Check a few of the citations to see if the material could have come from Plough Library or other Memphis area libraries.

Look for strange layout or formats in the paper. Some students will hand in papers with words that appeard as hyperlinks online, but on printed paper they are underlined or grayed out.

Even more obvious, the student might hand in a paper with the address of the website or the name of the company where he got it printed at the bottom of every page (i.e. "Thank you for purchasing from TermPapersAreUs").

Be alert to papers that are only on topic for the first and last paragraphs, with seemingly incongruous material in between. The student may have tried to tailor an internet paper to fit the assignment.

Perhaps the best detection strategy of all: get to know your students' writing style before they turn in their research papers. Anything that is way beyond or below the student's typical level of writing should be suspect.

Collecting Proof:
Once you suspect you have a plagiarized paper, the next step is to find the source of the plagiarism. Here, there is good news. Just as the Internet makes it easier for students to copy and paste, it also makes it easier for professors to track down copying. Methods of plagairism detection on the Internet can be broken down into two categories:

Free Sources

1. One easy way to check for plagiarism is to utilize search engines. Just type a suspect string of five or six words from the paper into Google or another search engine. Be sure to put quotation marks around the phrase so that the search engine will look for your exact string of words.
Here are some popular search engines:

2. Be familiar with the term paper mill sites that are avalable online. Try tracking down the suspect paper directly on their sites. For a comprehensive list, go to http://www.coastal.edu/library/presentations/mills2.html.
Here are a few examples:

 

Paid Services

Plagiarism detection sites are companies that compare student papers against material on the Internet. Some companies also compare against other student papers, encyclopedias, magazines, and online databases. At the end of comparison, companies provide a report to professors on which material in the paper might have been plagiarized, and the exact source of that material. Cost varies with site, but many offer a free trial.

Turnitin.com (also known as Plagiarism.org): Students turn in papers at turnitin.com, where each paper is compared against texts in the database and Internet texts. Report is e-mailed to instructor within 24 hours.

MyDropBox: Service runs submitted documents through three independent searches of Internet index, online reference sources, periodicals, and password-protected electronic document databases. Generates originality report with interactive features.

Glatt Plagiarism Services: Program eliminates every fifth word of student's paper. The student is asked to supply the missing words. The number of correct responses, the amount of time intervening, and various other factors are considered in assessing the final Plagiarism Probability Score.

EVE2: Download this software on site. Performs complex searches of Internet Sites. Generates a comparison report.
