Internet is a nice place,but unfortunately many people are abusing the power of “cut and paste”.
Especially the students are quite often involved in plagiarism (the statistic seems to detect a quote around 30%!),so if they are using the new technology to copy,we can use the same technology to discover the falsifier.
Turnitin allows educators to check students’ work for improper citation or potential plagiarism by comparing it against continuously updated databases using the industry’s most advanced search technology.
Every paper submitted is returned in the form of a customized Originality Report. Results are based on exhaustive searches of billions of pages from both current and archived instances of the Internet,millions of student papers previously submitted to Turnitin,and commercial databases of journal articles and periodicals;and it is completely web-based.
Are you a student? You are advised!
