Actually, checking for exact matches won't catch the students who change nothing but identifiers. But there's a really cool free tool provided by someone at UC Berkeley called Moss that does some sort of lexical analysis, along with pattern matching, that has helped me catch lots of unscrupulous programming students. (Yes, lots. The rare downside of teaching at a community college.) > I think chopping up an article into an array of sentences, and throwing a few > into google would be a good approach. And that's more or less what I do when I suspect plagiarism in a written assignment. I don't (yet) do this in any automated way; only when it seems obvious I should. Don't forget to surround the sentence with quotes for Google to reduce the amount of false positives. -c _______________________________________________ New York PHP Users Group Community Talk Mailing List http://lists.nyphp.org/mailman/listinfo/talk http://www.nyphp.org/Show-Participation
