plagiarism detectors

[bike5]

Has anyone in here that is a teacher or a student used any of the plagiarism detectors out there? I downloaded a trial version of one to see how it works.

I tried it on a paper I wrote about a trip to Hawaii I had. I wrote the paper all from my head without looking at anyone else’s work (WHY WOULD I? It was my own trip and my own experiences). Anyway, I wrote the paper WHILE in a 50 min. class (like 3 years ago) and guess what the plagiarism detector told me? It said I had 15% of my essay plagiarized and gave about 30+ sources of places on the Internet that had the same wording (mainly parts of sentences).

Is this stupid or what? With billions and trillions of sentences out there, how can you not plagiarize even part of something you write?

So anyway I didn't stop testing there, I tried an actually research paper I wrote (works cited and everything) and it came back telling me 45% was plagiarized :ohmy: When I know for a fact its not, I gave references to anything I used even the paraphrasing. I checked out some of the sources and I must say a lot of the sentences that matched were on other people’s essays not even related to what I was talking about but still using same parts of sentences. Then there were a few sentences that looked like I stole from other essays on the same subject (when they are my own damn words (at least I wrote them not from anyone else’s works)).

For the most part, almost all the text it says is "copied" can be shown when going to the "original" texts as false, just a coincidence of using parts of the same sentence structure. This however is not the problem, how many teachers actually take the time to research EACH and every piece of sentence that says it’s plagiarized? Its impossible with the amount of papers, so what do they do? They trust the results and might grade someone down or even file a report on you for plagiarizing in higher academic levels, not to mention just seeing a high % might gain you a "bad" perspective on all other future projects.

What are we supposed to do? The concept of detecting plagiarism through a computer program is a good idea but I don't think it is as effective and accurate as everyone thinks. I can see it working against someone who actually does plagiarize someone whole essay or something but for most people it could give the teacher a bad impression of their work when all their work could be "original" to them.

So for anyone using this "test" to grade someone else’s paper, don't trust JUST the % marked plagiarized. To be accurate and correct you will have to do some digging and researching to make sure the text was or was not copied.

If anyone wants to add anything to this please do.

BTW: After submitting what I just wrote ^, according to the program I have plagiarized 7% and it gave exactly 21 soruces to verify the "copied" text parts... :|

Hey, you plagiarized my post for 3.72 years ago! :) Just kidding.

What a bunch of junk that is. Of course someone else has used some of these very same words in a sentence before.

I was accused of Plagiarizm in my Senior year creative writing class. It was a situation very similar to yours. I wrote a short story about my first enduro race. In fact, I wrote the story and turned it in as a competition piece while I was a JR. My teacher gave me a B- and said that it wasn't worth submitting to the newspaper for the competition.

Then, the next year (at the same high school) while in creative writing we had an assigment to do a short story, so being the lazy SR. that I was, I recycled my story from the previous year to keep from having write another one. I was surprised when I recieved a note stating that I had a meeting with my creative writing teacher.

She then proceeded to tell me that I would have recieved an A+ but she was pretty sure that I didn't write the story myself. I must have copied parts of it from somewhere. Oh, I went off about how the basis of the story was my own experiences.

The only problem I had wasn't I couldn't argue too much for fear that she might talk to my teacher from last year and I would get busted. Oh well.

That sounds like something I pulled, except I used my older sister's essay on Emily Dickinson for a Lit class. Normally, I'm not that lazy, but for some reason I didn't even retype the essay. I simply erased her A- (it was in pencil), made a new cover sheet with my name on it and turned it in. I still can't believe I did that, especially since it was the SAME teacher that my sis had years earlier.

I got a really cold glare and a B- from Teacher. ;)

I had a similar experiance in college where I wrote a paper on the family orientation of deer hunting. The teacher gave me a B on it and put right on the paper that he knew I had to have copied it from somewhere altho he couldn't prove it. I wrote the entire thing while bartending the night before it was due and had to make up sources so he thought it was researched as instructed. I wanted to argue but was also afraid of getting docked further because I couldn't provide any of the bibliography cited.
Funny thing I turned the same paper in for anotther class the next year and actually got an A+ with the comment "extremely well researched and an obvious commitment to the topic".

This is such a can of worms...and it has two sides to the story.

First, I used to be an English teacher at the high school level (until I realized my 2 week paycheque was enough to cover about 6 days). There is a real concern with plagiarism, not just as a punishment measure for lazy or over-ambitious students, but because there are an alarming number of kids getting through the system who are functionally illiterate. (They write for Dirt Bike magazine...and vote Democrat)
IF a good teacher has enough time to get to know a kid's writing, it becomes obvious when plagiarism occurs. A sudden change in cadence, sophisticated vocabulary, or citing cultural references out of his/her demographic (ie. a 13 year old who sprinkles a lesser-known quote from Mahatma Ghandi might raise an eyebrow) are cues. It's not that different from a musician who winces when someone plays a guitar that's even marginally out of tune...when most folks don't notice the difference. You develop a sensibility for detecting these things. I taught 150 kids a year, but if I found a naughty note on the floor, I could tell by the handwriting and a couple of misspelled words who authored it.
That said, lazy writer also have lazy sources, and a good teacher becomes familiar with the reference books in the school library, the Coles Notes for class novels, and popular file sharing and websites from the internet or Microsoft Encarta. That's outright plagiarism, not subtle, and easy to catch. Of course, those students tend to be confrontational knuckleheads and want to play lawyer when they get caught, so they burn up a lot of time we could use...ummm....teaching...
The plagiarism sites that are out there, to me, are like DNA testing. You're going to get partial matches for phrases because we learn to write by reading and listening, and one tends to follow a pattern. For instance, if I told you to use the word "furtively" in a sentence, 90% of people would write the word "glanced" in front of it. ie. "John glanced furtively around the room." It's an underused word that we only hear delivered in a predictable way. In a given essay, especially when one develops a certain ease with writing, you're going to find expressions, colloquialisms, adages, stylistic borrowings, and a discomfort with tougher vocabulary that forces the student to produce very predictable sentences. That's all part of the discovery process, something one works through to become a flexible, fluid writer. Unfortunately, if you run that essay through a plagiarism checker, it's going to light up like a (you guessed it) Christmas tree (see, you knew I'd say that, right!)

Back to my DNA thing; if your teacher calls you to the carpet over potential plagiarism, it's probably just because the sum of all these little common expressions and partial sentences added up to a potential problem. Unless you're at the Master's degree level, referencing and quotations are difficult to execute without "accidental" borrowing. What the teacher is really looking for is an essay that is either entirely stolen or a hodge-podge of 3 or 4 major sources jammed together. That's a "DNA Match." You're busted. Go to jail. 30 kickstarts of a drowned WR426. However, a person clever enough to bring 5 or 6 lesser-known reference works together in a writing style that is even close to being consistent throughout is a person who is clever enough to write without plagiarizing. It would take less work to be original.
All your teacher wants to know is if you're an illiterate hiding behind borrowed work (and many illiterate people are highly intelligent and can fool very experienced teachers), or a decent student who is being lazy and dishonest. Flip the coin for a second. A teacher who uses a plagiarism program as the sole means of detecting borrowed or stolen work is also lazy and hiding behind an imperfect tool. If the essay turns out to be 93% "plagiarized," but no one paragraph is attributable to a source, all you're guilty of is using average sentences in an average way. Bottom line: the plagiarism program is just one more tool in a teacher's quest to evaluate the true talent and writing level of his/her student. If you're feeling like it's a "guilty until proven innocent" accusation, you need to have a heartfelt discussion with your teacher. If you do nothing, you'll lose. If you get in a confrontation, you'll lose. If you are genuine and patient, you'll win.

Go win.

Lot of good points made Detonator. Funny as it seems I have not actually had a essay ran through one of these in a current class YET. I have a critical thinking English class in college now and the teacher wants all papers turned in on disk to run them through the detectors which is why I got interested in how these worked. One thing I really didn't not like at least about the one I tried was it did not catch when you paraphrase something since you just use the "()" after the line without using the " "" " in there. And if a company says they can detect that, then I would ask how they could distingwish (yes I know its wrong) a cite from just something like - MX (Motocross). Would it see the (Motocross) or (yes I know its wrong) and think it was a cite? Especially since you can cite within a sentence also not having to be at the end.

Anyway I will have a final draft submitted in a couple weeks of one paper so I will see how it all turns out. I think this is a good critical thinking topic in itself anyway, maybe I can get some extra points for bringing it up....I wish (maybe in high school_. :laugh:

 

[Detonator]

Your professor is more than likely using the policy of handing work in on disk as a deterrent for those who were considering short-cutting the system. The problem with the computer thing, as you point out, is that even if the software follows perfectly the rules of grammar, most writers don't, so you have a program finding issues that aren't there. Check out translation software...being a bilingual English/French speaker, I can report that most translation software is a joke.
I think this would be an excellent critical thinking topic, and you'd do well to organize an interview with your prof or one of his/her colleagues. Just be sure you're doing it because it interests you, and not for brownie points. I always had a hard time respecting suck-ups!

All my best lines are plagarised........there is no problem.

I just read a website that says that most papers will show up 5-15% plagerized by these dectors. When a paper shows up 20-30% it should be "suspect". Then if it shows up 70%+ it most likely is plagerized. I guess most teachers know that.

When a paper shows up 20-30% it should be "suspect". Then if it shows up 70%+ it most likely is plagerized. I guess most teachers know that.

What about 31-69%?..lol I guess when you write a paper I hope you don't write on a popular topic or write using common sentence structure because getting past the 20% range doesn't seem to hard to do. If then, your a suspect? And you think your teacher will take the time to review each part that is suspect if they have to review 50+ lines of text with different sources.

I think (my opinion is) the problem is that you could easily be considered a suspect and make a "suspect" or bad first imprssion to a teacher that could effect the way they read your papers in the future. I am hoping most teachers are aware of this and I am sure "most" are but it only takes ONE to ruin 8 years of a college 4.0 gpa. (Although thats an example and not mine...I wish..) I am in my seventh semester (12-17) units each semester and I have got ALL "A's" except for 2 classes. :bang:
