I am curious about how useful SafeAssign is for detecting plagiarism from online sources. I tested it myself, uploading a paper that I lifted entirely from a published text, and it found only 25% matching, all of which came from the citations. Of course the citations have been used elsewhere! The tool did not flag any of the actual text. A faculty member just reported a similar finding, with only 3% matching, when he was aware of a significant percentage of the paper being plagiarized. Am I misunderstanding how SafeAssign works? Is it simply to find plagiarism within the institution, ie students copying from one another? Or is it simply an ineffective tool?
