Asked 26th Feb, 2013
How to check plagiarism?
I am not sure whether this question has been asked on research gate or not. If this topic is already their please send me link. One of the problem we are facing is to check duplication (copied from net or research articles or thesis) in a scientific document. When you get document from students or junior colleagues or from your team members you are always worried whether this is orignal writing or copied from net. Though their are number of software and software on net, it is difficult to trust on these software. I wants to know from my colleagues at this platform what is best way to check duplication. Is their any good server or service which can check duplication with high reliability in scientific writing (can check duplication in literature databases such as PubMed).
Most recent answer
I think using Turnitin will be the best solution. I advise you not to use Plagiarism Checker X if you do not have a software license.

There is some good advice in the above comments. In combination there are software- and online checkers for plagiarism.
You can try these and similar software and sites to help identify plagiarism. If identical texts are found, to verify that it is not a quote, with a refference to the author.

you can use http://plagiarisma.net/ . it is freely available tool for this .
Our university now use TurnItIn for all undergraduate submissions, but I'm sure you can use this for any type of submission.
Sometimes if plagiarism is suspected it is just useful to type a block of text into google, as Google Books would normally pick this up or whichever website it may be from.
You can use this tool not very precise but gives broad idea
or use viper. This is a good freely available tool for plagiarism checking

We use a service called "Safe Assignment", which comes with the Blackboard 9.1 learning management system. The advantage of using "Safe Assignment" is that it also checks all submissions against all other papers sent by students in all courses. Usually, web-based plagiarism-check systems only check for portions of text copied from the web, but this one also lets you know if a student is copying content from his or her peers. The limitation is that you have to be using Blackboard as your institutional LMS.

Student plagiarism is often possible to identify by style of presentation. A computerized search of plagiarism can also be used. But they are easy to get around, so the results may be unreliable. In responsible situations, I prefer to search in Google on key phrases.

As Reviewer I had this bad experience one time. It is not so common, but I consider this a serius problem. The first thing that I do it is to check the other papers of the autors. There are specific tools to find publication duplication....
I often need to check papers for plagarism as I teach Academic writing. I have used turnitin although I did find the software often gave comparisons between work handed in by other students and even by the same student. This tended to give very high percentages of plagarised work when possibly it wasn't. I am sure that much of the other software will produce similar results.
I have found that most students dont plagarise but when they do it is poorly done with many obvious flaws in cohesion and grammar. Often the easiest way of spoting a copied section of writing is the change in style. I have found essays in which the font changes for a paragraph or the method of citation changes. A sudden change in the level of prose or the complexity of the vocabulary used is usually a good indication of plagarism. It is a huge problem as there are many sources of plagarised essays available on the internet. I did have one student who put in his list of references www.writemyessay.com which was a bit of a giveaway.

You can do the followings:
1. It is better for not to go for free plagiarism check software.
2. Always go for reputed reviewers( although very difficult to find out one)
3. for high level plagiarism check you can use ITHENTICATE PLAGIARISM DETECTION which is being used by top publishers.
4. Apart from the above an intelligent person can detect a plagiarizer document very easily by going through it, since the flow of language will not the there i.e. you will find variations in language level.

Are dissertations written by international students in the U.S. and industrial nations being plagiarized by professors in American, Canadian and English Universities?
Our journal (Journal of Mountain Science) will first check the plagiarism of a manuscript by using ITHENTICATE after it is submitted. This crosschecking system will compare the similarity of the present paper with the millions of papers previously published and articles in the internet (usually by google), and provide a separate similarity index with one single paper and the total similarity index.
The checked result is displayed in two columns, the left column is the checked paper, the system use different colors to mark the similar contents, and right column is the list of the possibly plagiarized papers, which are listed in the order of similaritity index percentage.
The marked color in the checked paper is corresponding to the color of the possible plagiarized paper.
We usually set a similarity index for rejecting a paper. When the total similarity index is up to 40%, or the similarity index with one single paper reaches 20%, the manuscript will be directly rejected.
When the similarity has not reached the set level but is relatively high, we will read the whole paper and check which part is taken from othe papers. If the abstract or conclusion is almost the same with one single paper, we'll definitely reject it too. If most figures and tables are the same with one single paper or the key data are copied from one paper, we'll reject the paper too.
If only the introduction part or discussion part is taken from other papers, we'll require the authors to revise the paper, and suggest them organize these two parts in their own way and write them in their own words.
We start to use the iThenticate software from 2010. At first, we found that a relatively high proportion of papers plagiarized some paragraphs from other papers, and some even copied a large part of contents from others papers. Now high plagiarism rate can be rarely seen for this year's new submission.

I have recently used the software Turnitin, I found it to be pretty good, except for the fact that in my domain area, legal studies, we do require a lot of citations for case comments. Turnitin has a few issues on that count, otherwise it is a pretty decent detector of plagiarism

Raoof: Thanks. Papers not on the Web, last year's student term papers, and term papers from friends at other universities are not scanned. Like all plagiarism checkers, there is no built-in intelligence to reliably flag the subtle difference (to software) between a quote or paraphrase or idea that has been reproduced with the source being correctly cited, and missing or incorrect referencing.

Mark put his finger on a key part of teaching students to write original essays and research reports. Elaborating on this, it is possible to set up situations where a student must do his own research. Years ago I settled on the formula of asking for only one paper at the end of the semester. Along the way I review the students' data, on note cards or digital supports, as well as their schematic outlines, making suggestions for improvement. Rigorous documentation in footnotes and a reference list are required for a passing grade.
In the end there are usually a few dishonest students who insist on using the "copy-paste" method, without quotation marks or citations. It's usually evident, and Google is enough to nail down the original or at least cognate sources. I experimented with some online plagiarism detectors with poor results, perhaps at least in part because my students write in Spanish. Many students use on-line scholarly report sharing sites (in Spanish there are two big ones: El Rincón del Vago -which translates as "The Lazy [Student's] Corner"- and Buenastareas.com -"Goodhomework.com"-). These sources are used so frequently that they often come up near the top of the results of a Google search. Some of the plagiarism checkers don't detect them.
Regarding Ian's mention of last year's papers, I insist on printed and digital versions and keep a file of the latter; this file can also be searched electronically. If two or more professors teach the same course, then a bit of collaboration is called for.
Getting students who are used to passing courses by plagiarizing to have the experience of writing an original paper can make a big difference in their lives, raising their self-esteem and in some cases setting them on a more honest path for the rest of their educational and professional lives. I have gotten feedback from graduates, years after taking my courses, that testifies to this.

That's an interesting and well-reasoned article, José. Thanks for sharing it here. It's from 2007. Six years later it looks to me like we haven't made any progress in dealing with faculty plagiarism. I have spoken out on specific cases, only to find that some colleagues find whistle-blowing to be a worse crime than plagiarism, while others turn a blind eye to the problem to avoid making waves. When an institution has a double standard and students receive tougher penalties than professors for plagiarism, there is a grave ethical problem that needs to be addressed.
Here's a very good article in Spanish on plagiarism that I give to my students at the beginning of each semester, as part of the education process that I mentioned in my last post:

Are we to blame? I believe that we lecturers should now set the example by templating and reserving the bottom left corner of each PowerPoint slide to include the author and date of our source. For chalk-and-talk, a verbal reference should suffice.
3 Recommendations
You're right, Ian. A PowerPoint format is no excuse for plagiarism, including images, which are just as much intellectual property as words. I like putting a subtle vertical strip on one side of the image, with the author's last name and year. Quotes should have the source under them, of course. In the end I flash the bibliography at the audience, more for the purpose of showing due respect for intellectual property than anything else. It is essential that we set a good example.
4 Recommendations
To check plagiarism effectively you need two approaches: (1) Web based (Google does make the difference), and (2) a deep insight into the body of knowledge of the text under consideration plus the most cited literature. Caveats: approach (1) does not work well in such cases as paraphrased texts; approach (2) consumes a lot of your resources relating time and cognition.
So, my answer to the question stated in your last paragraph is 'no'.
3 Recommendations
When I was teaching undergrads, when they copied and pasted usually two things would stick out; the flow of the information they would be giving and also the formatting will change. However, now there are a number of software you can use for that. I guess some other people have discussed on that. In one class I took, the work was submitted straight to an online plagiarism checker.
2 Recommendations
There may be software, there may be honest effort but plagiarism is something which needs a transparent approach. I am a green horn who has a lot to learn but I try to work honestly in my research outputs. However, in India I find plagiarism is taken quite lightly and persons brag about papers where they have plagiarized liberally. This happens because in a number of cases no proper action is taken. An effective anti plagiarism policy is needed and researchers need to be made aware of different facets of plagiarism before it is too late for them.
4 Recommendations
I am also a green horn like you Soumya, the best advise I ever got on plagiarism was, "If you will need, a plagiarism software to check whether you plagiarized, then you probably did plagiarize." This helped me to write my own stuff, paraphrase and quote. I quote liberally, It's better to receive a complaint that you had too many references than that you plagiarized.

@Soumya, in Germany (my home country) people lose their PhD, MD etc. quite easily, if plagiarism could be verified.

Michael that is the difference between your country and mine. The approach taken in your country is the right one but in India I see academicians openly engaging in plagiarism and walking free by using their political clout or other means. The worst part of this process is that young talents grow up knowing that plagiarism is something which is trivial and can be practiced liberally.

What I personally feel is that:
1. It is very difficult to detect plagiarism. No doubt there are lots of software, but they can only detect plagiarism if and only if the materials are copied from Internet/ Materials are available online.
Hence the plagiarism detection software helps to a great extent.
2. It is really painful that most of the time researchers under pressure use to do it.....

We use TURNITIN where students upload their text files and they are checked against all on-line works. Accepting that their are limitations with these software programs you can always discourage plagiarism by telling students that TURNITIN is used every year across the board and it is very successful. Their choice is to believe you or test the system. In student essay/projects a sudden change in style, phraseology, vocabulary, format, referencing etc is suspicious and invariably indicates plagiarism (see Vladimir's comments)
Viber free plagiarism tool can also be used. It is free of cost but it's good. It is alternative to turn it in.
Viber is decent, the others are simply paste and text. I recently needed to check students papers .doc/.docx format as well as PDF and Power Point (PPT). This is a great solution and gives you unlimited scans https://www.writemypaper.net/free-plagiarism-checker-for-students-online/

I have used Grammarly and I recommend it, we pay it among four colleagues and it is used without problem.
You can use turnitin.com . Great results for checking plagiarism.
Grammarly is not a good option as it doesn't work accurately. So, Sir you must not rely on this and most of freely available softwares.
Thank You
Turnitin is really very helpful but you need a paid subscription. However, even with Turnitin, remember to look into the similarity ratio. For example, it would make sense to exclude bibliography in the similarity as well as short matches. This can change the similarity ratio. Also it is important to check inside the matches to see if there has been too much "inspiration" from one source. Usually this has to be 1% maximum. I have also been told of students trying to beat the software by adding words invisible to the naked eye but visible to the software (the software does not detect colour) and which can reduce similarity drastically. So be careful with similarity ratios which are suspiciously low.

I wonder can African countries benefit from the "TurnItIn" plagiarism analysis software or any other similar software that offers better results?
Gajendra Pal Singh Raghava sir
Free softwares are not giving accurate similarity index . turnitin/ Ithenticate both are best options.
The description of popular similarity checking softwares are given below.
Urkund is a web-based application that conducts server-side plagiarism detection. The solution to detect plagiarism is integrated and automated. This is a paid service that utilizes a standard email program to upload documentation and display information. This program handles 300 separate types of submissions and checks all accessible online sources. The educational sources of documents are given more priority while searching.UGC provides this software to universities of india for similarity checking.
Ithenticate for any text document is an effective tool for web-based plagiarism detection. Installation on a client computer is not necessary. Input materials are comparable with the references accessible on the site in this case. Many well-known journal publishers utilize this well-known method. It is a professional fast plagiarism checker that is easy to use. This is meant for institutional use instead of personal use, but essentially this offers a restricting feature for consumers of the specific identification of plagiarism, such as students of master and doctoral education. this allows them to check a document of up to 25,000 words.
Turnitin is a successful web-based tool. Detection and reporting is done remotely in this method. 15,000 universities and 30 Million students have now approved Turnitin because of its user-friendly design, broad repository help, robust plagiarism tests and structured report production. It can be seen as one of the best plagiarism checker.
There is no software which check plagiarism only similarity level can be checked.
Arun kumar sharma
Gajendra, turnitin has been found to be useful in highlighting aspects, scale and potential sources of plagiarism. Others tend to insert parts of a text into Google if they suspect plagiarism to ascertain whether this is the case or not.
