Plagiarism Detection Software

[jlenrow]

With Turn-it-in being sold Turnitin to Be Acquired by Advance Publications for $1.75B | EdSurge News, I want to be prepared in case the new owner makes drastic changes that we don't like.  What plagiarism detection software do you use, do you like it, and does it integrate nicely into Canvas?

Thanks for any info you can provide.

Jon,

Thank you for bringing this to my attention. We currently use Turn It In but have been under-impressed with how it works for us. I have just begun the process of reviewing what is available. I see in the EduApp center that Canvas has a partnership with Urkund, PlagScan, Unicheck, and Vericite. If I missed any, could someone let me know? I haven't found any current comparisons of these products in the community. Hopefully your post will encourage that.

Hello, Jon!
Unicheck is a fast and efficient solution that works wonderfully within Canvas Plagiarism Framework. We cover over 40 billion unique pages with our web search and with full reports generated in minutes, as well as 99,9% uptime, you can be sure you're getting the most thorough results in the quickest time.
We'd love to tell you more about our service, so if you're interested, please feel free to leave us a request for a demo.

We've been using Turnitin with Moodle for years.  Now that we're migrating to Canvas, we've been testing Unicheck and Plagscan to see if we want to stay with TII or move on.  We didn't like the limited content repositories that Unicheck scanned compared with the broad base of content in Turnitin.  Still testing Plagscan.  In addition to the repositories scanned, there are differences in the implementations.  For example, Unicheck integrates only via the Plagiarism Detection Framework, meaning you use Canvas assignments and grading tools, and Unicheck provides only the plagiarism scanning, scoring, and reporting.  Plagscan integrates and uses Canvas assignments and grading tools as well, although I believe it is done as an LTI tool, not a Plagiarism Framework tool.  Turnitin offers both options, but each method has some limitations.  Our faculty absolutely love the QuickMarks tool in TII, but that's only available if you use TII as an external tool, which then means you're not using SpeedGrader and Canvas' own very good tool set.  But that said, we're still not sure what we're ultimately going with.

Hello, Tony! Actually, Unicheck does also integrate via LTI, as well as Plagiarism Framework.

Would you mind elaborating on how the quantity (and quality) of the scanned content was determined? We use a real-time web search instead of a web-archive and it’s very thorough and brings the most relevant results from up-to-date sources.

And of course, there are lots of other important factors to consider when making a choice, such as the uptime, quality of support, etc. They can impact your user experience in a major way.
