Plagiarism Checker

Those of you who read my plagiarism series will be happy to learn that the war against plagiarism has just acquired a smart weapon.

Darren Hom, who teaches "science, Bible, and study skills classes" to "middle and high school students at Highlands Christian Schools in San Bruno, California," grew tired of tracking down plagiarism using Google:
I ... had to spend a lot of time doing several Google searches on each paper, as some students would copy parts of their papers and write the rest themselves. Using this method, I had to remember to type quotation marks around each phrase, or else the search engine would not find exact copies of the phrases I was typing in.
Rather than just complain like the rest of us, he decided to do something positive about this problem. First, he checked available services:
I spent a few months looking around for a better way to check for plagiarism. I rejected most of the solutions I saw because they wanted me to buy subscriptions to their services. Some were free but required me to submit an entire student's essay online, which was not possible for me because my students turn in printed copies of their work. The remaining free solutions were not any easier to use than Google, since they also required me to type special operators and would only search for one phrase at a time.
At this point, I would have given up and reconciled myself to using Google ... but not Darren Hom:

Because I didn't find a free and easy way to check for plagiarism, I learned Web programming and created one myself.

I'm impressed -- and even more impressed by his search engine. Here's what it offers:
PlagiarismChecker.com allows you to search for several phrases from a student's paper at the same time without having to type quotation marks or special operators, which most search engines require if you're trying to look for exact copies of a student's writing. This site automatically adds the quotation marks and special operators for you .... PlagiarismChecker.com is free and works on any papers, whether students e-mail them to you or turn in hard copies.
So if you're tired both of plagiarism and of Google, try out Darren Hom's Plagiarism Checker.

Jim Davila will be happy.

Can you verify that www.doccop.com is working?

 
At 4:59 AM, Blogger Horace Jeffery Hodges said...

Mars, you'd do better to ask Mark McCrohon about that, since it's his baby.

I took a look at the DOC Cop website, and it seems to be up and functioning -- if that's what you meant by 'working'...

If you meant to ask if DOC Cop works, then I don't know. I've never tried it. I use my own methods to uncover plagiarism.

Many institutions limit access to their online information. Making this information available will be an asset to all.

 
At 3:54 PM, Blogger Horace Jeffery Hodges said...

Yes, plagiarists, go ahead and purchase a paper at "Research Papers."

One warning though: They can't consistently spell "college" correctly, and they don't know the difference between a restrictive and nonrestrictive clause, so don't expect that promised A+ paper.

I guess that's actually two warnings . . . maybe three. Well, you can always expect the best bargains from Gypsy Scholar.

Yes, students, let Dianna Rose help you cheat your school and yourself.

But you'll probably get caught.

I guess using plagiarism detection software means trusting a service, because you should be very careful about giving out your work to someone else. I am a professor of English at the St. Michael's College and can share my experience of using an online plagiarism detection service. It is called www.plagiarismdetection.org. I am using it for over 10 months. I have tried them in many ways. For example, I have scanned one document in Nov., let's say. Than I forget about it for a couple of months and scan that same document in March. It does not find any relativity to other documents, so I can be 100% sure these guys are not keeping the databases. Everybody heard of scandals with turnitin and I don't want my students to participate in someone else's database gathering.

With all due respect, Anonymous, you don't sound like a professor of English, for your 'comment' is full of grammatical errors, and since I get a lot of advertisements posted in the comments section of my blog, I suspect that your 'comment' is just another ad.

But since I'm all for eliminating plagiarism, I'll let the ad stand this time.

Dear Gypsy Scholar, I am the Anonymous poster you are referring to in your previous post. Let me express my sincere gratefulness to you for nor removing my comment, which you suspected to be an advertisement of a website. I have placed the link because I do believe that only educators in their united efforts in combating plagiarism can preserve the value of education.
Now, I would like to explain how students can benefit from using plagiarism detection software. There is such thing as self-plagiarism. Also, many educational programs use group projects and study groups, which involve mutual grade for all members of a group. For this purpose it is not a bad idea to check upon the parts of the projects done by colleagues.
Thank you again and good luck with your blog!

"Professor at St. Michael's College," thank you for the additional comment. I was suspicious about the original comment primarily because of the poor grammar. I must infer that the original was hastily composed though I still find the errors disconcerting in a professor of English.

You could better avoid suspicion by signing in with your real name, but I suppose that you may have good reasons for signing anonymously . . .

Anyseo, I suppose that site's useful, so I'll let the link stand even though the writing there is ungrammatical -- one expects better from a site for uncovering plagiarism.

I teach a composition class and I have to deal with plagiarism on a regular basis. Our school used to have turnitin but it got too expensive so they canceled their subscription. I am now using a service from Plagiarism Checker and I like it a lot.

 
At 7:03 AM, Blogger Horace Jeffery Hodges said...

Thanks for the unsolicited ad, Kathleen. I usually delete advertisements, but I suppose that this one's okay.

"DOC Cop is on the web at http://www.doccop.com and processes documents free of charge."

That may have been true in 2006, but it's a bit misleading based on how it works now. Comparing documents to each other - free. Comparing a *small* chunk of text (997 characters) to the web - $3.

I really appreciate the efforts you put into reviewing these useful resources. I was wondering if you’re planning to update the list anytime soon? In that case, you might be interested in trying out our plagiarism checker tool
