Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many professional writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my paper for plagiarism and then to hire a professional writer to fix your task quickly if you’re busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue working on their assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

• Scans your paper against billions of sources.
• Identifies text that may be flagged for plagiarism.
• Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

• A chart or graph from another source
• A paraphrase of an original source
• Several sources’ ideas summarized into your own paragraph
• A direct quote
• All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

The EasyBib plagiarism checker is conveniently available 24 hours a day and seven days a week. You can cancel anytime.  Check your paper for free today!.

Best Plagiarism Checker Tool for Researchers — Top 4 to choose from!

While common writing issues like language enhancement, punctuation errors , grammatical errors, etc. can be dealt with the help of proofreading tools and editing services , the pervasive concern of plagiarism is difficult to tackle. This unethical act is a serious concern among writers, students, researchers, and other academics. Hence, the need for plagiarism checkers is in high demand to make your academic paper unique.

Table of Contents

Why Should I Use a Plagiarism Checker?

Plagiarism is a non-forgivable offense, especially in academia. Moreover, if caught (which is easily possible with the use of the best plagiarism checkers ) can lead to researchers jeopardizing their reputation in the field, getting expelled, or even being terminated from their respective universities.

Research papers and any form of documentation require you to do thorough research, develop the structure, and follow the provided guidelines. A lot of people prefer to renounce all the hassle, and that’s where things go wrong. Plagiarism is not always an intentional act. It could be a result of ignorance, poor time management, confusion about what constitutes plagiarism, etc. However, this could be easily avoided by using an online plagiarism checker .

You should use the best plagiarism checker and scan your papers because:

• Openly available resources available through plagiarism checkers detect plagiarism comprehensively.
• It highlights exact plagiarized content for easier navigation.
• Plagiarism checkers often provide percentage matches.
• Most plagiarism checkers detect incorrectly paraphrased content as well.
• The use of plagiarism checker tools displays the honest intentions of the writer.

How to Choose the Best Plagiarism Checker?

A plagiarism checker is software used to detect imitation of someone else’s work. The internet is overflowing with multiple plagiarism checkers with varied features. How do you decide which plagiarism checker is best suited for your work?

Here we discuss 3 major factors to consider before selecting a plagiarism checker tool.

1. Cost of the Tool:

While there are several free tools available online, they are not as advanced as paid ones. Free plagiarism checker tools are easily accessible but fail at offering comprehensive checks. In most cases, they do not detect plagiarized content from all sources. On the other hand, paid plagiarism checker tools often offer advanced features such as spelling and grammar checks , calculating the authenticity score of the document, and the ability to integrate with websites and third-party applications, along with comprehensive plagiarism checking across several databases.

2. Ease of Access:

Digital tools are supposed to ease our work. However, tools can complicate our work at times. Thus, having a user-friendly tool is essential, especially while looking for a quick and easy way to check your papers.

3. Scope of the Tool:

Determining the scope of the tool and how it aligns with your requirement is crucial. Whether you are looking for a standalone plagiarism checker tool or a more comprehensive suite of writing and proofreading tools must be clear. Advanced writing and language improvement features that go beyond just plagiarism detection are also offered by some plagiarism checker tools.

• The best way to stay original is: staying original. Don't get me wrong. All I want to say is, think with your own imagination. Paraphrasing is actually detectable if it is not done properly. Also, if you are doing it, you should not forget to add an in-text citation properly.
• Another important thing is to keep track of your work from the very beginning of your work. You can use cloud services like Evernote and Pocket to keep track of URLs, PDFs, Blogs, Websites, and Other Works.
• Unorganized papers often lead to plagiarism. You should be very careful while copying word-by-word. You can use "Quotes" to highlight the part which is copied with a source.
• Never trust Free services. Writing about the thousandth time, Do not use free tools. They will only lead you to false results and the risk of getting plagiarized with your own work. Paying someone to check your work on Turnitin will only lend you to hazard.
• If Your paper is an assignment, always do everything as instructed by the professor.

Best Plagiarism Checker Tools for Research and Journals

Without any doubt, Turnitin is a good tool to detect a similarity between the strings, whether it is a research work or an assignment. It has a huge database of research work and it is capable to find similarity in your content with the previous works.

A common myth about Turnitin is that it is a perfect tool. It is Not! Also, it is not a deciding tool   that you have actually plagiarized. Instead, it shows results to your professors for possible similarity among previously submitted work. That depends on the setting teachers are using. Only the examiner and you (human) can judge whether you have plagiarized or not.

Plagiarism Checker X

Plagiarism Checker X is the best alternative to Turnitin for many reasons. It provides some of the coolest features for students and professors. Some of them are bulk uploading, side-by-side comparison, automatic citation and multiple language support. It is the only tool on the planet which provides offline check after two consecutive checks.

You can play with the free version to test the waters before going for a premium one which is also available for less than $40 for a lifetime. It is being used by several universities and top companies as their standard tool.

PlagiarismcheckerX supports All Windows Platforms and you will be required to download .exe file to work with this plagiarism checker for academics.

It supports macOS, Android, iOS, Windows, Google docs, and have a web application.

Plagiarisma.net

After a considerable amount of research, I came to the only Free tool which is safe to be used for research work. It uses Google Scholar search results to detect similarities in your content. Plagiarisma.net is able to detect more than 10 billion (as they claim) search engine results and it can be used from their website as well via their Windows application. But take this advice with a grain of salt.

Note that Plagiarisma only supports Windows operating systems.

ProWritingAid

Loved by some of the best selling writers, ProWritingAid is a decent grammar editor and contextual writing editor. In the premium version of the software, which is available on Apple devices, Windows, Google Doc, and Scrivener, has an integrated plagiarism checker.

MOSS - Plagiarism checker for Code

(Measure of Software Similarity) or popularly known as MOSS is a tool that is very specific to the task of finding copied content for programmers. It is the (perhaps) best possible plagiarism checker ever created to detect plagiarism in software codes and programs. It was created in the Stanford labs in 1994. Since its inception, it is being used in several classrooms and research works to detect similarity in codes.

Bottom Line

The best way to protect your research is to keep it confidential. The above tools are tested and provide at most security to your data. Plagiarism can ruin your career and is unbearably frustrating. I hope the above tools will help you to write better assignments and get better grades.

Best wishes.

Ultimate Guide to a plagiarism detection tool for Academic Research

Defining plagiarism – types and examples.

Plagiarism occurs when you replicate the thoughts, ideas, and words of another without giving them the credit they deserve . 

So, when you do research online, make sure you 1) cite the source and attribute the credit when it’s due and 2) blend the reference into your own content. 

We have talked about some of the Best Academic Writing Tools here. 

Plagiarism may be classified into several types:

• Plagiarizing from your own work- this is when you copy sections of your own work and offer it as new material.
• Plagiarism from other sources- This is when you copy content from other sources without crediting the original author.
• Paraphrasing without attribution is when you steal someone else’s content and alter the words around, but you don’t give credit to the original author.
• Quoting without attribution is when you utilize someone else’s text without crediting the original author.

All of these sorts of plagiarism are considered cheating and can result in severe penalties. It is critical to understand the many forms of plagiarism and to always give credit to the original author anytime you utilize someone else’s work.

Why pay when there are so many free tools? 

There are several reasons why people would opt to pay for a plagiarism detection program when there are so many free ones accessible. As a researcher myself, my biggest reasons are:

• Accuracy – I want to be able to trust the tool to detect plagiarism in my writing. 
• Ease of use – how easy is it to trace the plagiarism and make the fixes
• Performance – does it tell me who’s content my writing is similar to?

Free tools either have issues with accuracy or are inherently difficult to navigate. Also, most of them do not show the source of plagiarism. 

Other than these, you may also consider the following. 

What features should you look for in a plagiarism checker tool?

When looking for a plagiarism checker tool, you should consider the following features:

1. Ease of use – The plagiarism checker tool should be easy to use, with a user-friendly interface.

2. Accuracy – The plagiarism checker tool should be accurate, and be able to detect plagiarized content quickly.

3. Coverage – The plagiarism checker tool should be able to detect plagiarized content from a variety of sources, including online articles, journals, and books.

Plagiarism is an ethical misconduct affecting the quality, readability, and trustworthiness of scholarly publications. Improving researcher awareness of plagiarism of words, ideas, and graphics is essential for avoiding unacceptable writing practices. Global editorial associations have publicized their statements on strategies to clean literature from redundant, stolen, and misleading information. Consulting related documents is advisable for upgrading author instructions and warning plagiarists of academic and other consequences of the unethical conduct. A lack of creative thinking and poor academic English skills are believed to compound most instances of redundant and “copy-and-paste” writing. Plagiarism detection software largely relies on reporting text similarities. However, manual checks are required to reveal inappropriate referencing, copyright violations, and substandard English writing.

Medical researchers and authors may improve their writing skills and avoid the same errors by consulting the list of retractions due to plagiarism which are tracked on the PubMed platform and discussed on the Retraction Watch blog.

Introduction

Plagiarism is one of the frequent forms of publication ethics violation. Researchers from all over the world may witness such a violation in their academic environment, and some of them may intentionally or unintentionally reuse their own or others’ intellectual property without proper processing and crediting [ 1 , 2 ].

Medical and allied health researchers are reminded that the Medical Subject Headings (MeSH) term defines plagiarism as “passing off as one’s own the work of another without credit” ( https://www.ncbi.nlm.nih.gov/mesh/?term=plagiarism ). This term was introduced back in 1990. Since then, global understanding of plagiarism has evolved to reflect a variety of unethical reuses of ideas, texts, and graphical materials [ 3 ].

The global open access movement has made it possible to easily reveal most instances of plagiarism, including copying texts and graphics across digitized old and new sources. The resultant retractions of erroneous and otherwise unethical articles have predominantly affected biomedical authors from China, India and Iran, particularly those who publish in low-impact journals [ 4 ]. The digitization of editorial management and regular scanning of countless online platforms have enabled detection of unethical reuse in manuscripts undergoing peer review [ 5 ]. Peer review digitization has also allowed exposure of instances of stealing ideas and materials which are intended for confidential and privileged evaluation by reviewers [ 6 ].

Intellectual theft is increasingly viewed as a serious ethical transgression in countries entering the global academic competition and adjusting their research and development policies to the universally acceptable norms. The awareness of various forms of plagiarism is growing due to the international research cooperation and quality publishing that involve academics with various language and cultural traditions. However, the issue of plagiarism in the globalized world of science is complicated due to variably perceived definitions of the unethical conduct, recycling of one’s own published materials, and unacceptable duplication of identical scientific information in different languages [ 7 ].

Editorial guidance on plagiarism

Global editorial recommendations contain a number of points instructing journal editors how to deal with suspected plagiarism and redundant/overlapping materials at pre- and post-publication stages. Core practices of the Committee on Publication Ethics (COPE) encourage editors to define plagiarism in their instructions and explicitly guide readers on how to reuse their published articles [ 8 ]. Also, all authors of manuscripts and published articles with misappropriation of intellectual property should be aware of their full responsibility for any wrongdoing at any stage. In case of suspicion, editors may question all co-authors and related authorities [ 9 ].

The Council of Science Editors (CSE) defines piracy and plagiarism as related violations of publication ethics with unauthorized reproduction of ideas, data, methods, and graphical materials, including those of the plagiarist (self-plagiarism and duplicate publication) [ 10 ]. Plagiarism, falsification, and fabrication are viewed by the CSE as different forms of research misconduct which may justify academic sanctions imposed by relevant national bodies and professional societies. To avoid any accusations of plagiarism, authors need to properly process primary literature and credit generators of ideas and other intellectual properties. Editors, in turn, should be skilled to identify copied and redundant materials by using advanced software and various other means.

Finally, the World Association of Medical Editors (WAME) reaffirms editorial intolerance of plagiarism in unpublished and published manuscripts and proposes to treat self-plagiarism differently, particularly in the case of linguistically redundant description of methods and other inevitable and unintentional duplications [ 11 ].

Creative thinking and plagiarism

Plagiarism is often revealed in works of novice non-Anglophone authors who are exposed to a conservative educational environment that encourages copying and memorizing and rejects creative thinking [ 12 , 13 ]. The gaps in training on research methodology, ethical writing, and acceptable editing support are also viewed as barriers to targeting influential journals by medical students and graduates [ 14 ].

The ease of accessing quality online articles of experienced authors, unawareness of plagiarism, and uncertain research ethics policies may push researchers in some academic institutions to copy, recycle, and produce unethical publications [ 15 , 16 ].

A large survey of Western and Eastern European Bachelor and Master degree students ( n = 1757) revealed diametrically opposite approaches to increasing awareness of plagiarism and arranging anti-plagiarism courses, with Polish students lacking training in these fields [ 17 ]. Additionally, a survey of 1100 undergraduate medical students in Pakistan pointed to a high percentage of unawareness of plagiarism (87%) and instances of plagiarism (71%) [ 18 ]. Finally, a nationwide survey of 706 Iranian medical graduates and faculty members revealed that the majority of the surveyees (74%) had not received any training on plagiarism [ 19 ]. The same survey revealed that 11% had not even heard about such an ethical transgression.

The existence of numerous editing and copying agencies preying on novice researchers, students, and authors may further complicate the issue and negatively affect scholarly publishing in China and some other non-Anglophone countries [ 9 ].

Instances of plagiarism

Several forms of plagiarism can be distinguished based on confounders of this misconduct ( Table I ). Depending on author intentions, plagiarism is classified into intentional and unintentional (accidental) forms [ 20 ]. The former is a deliberate unethical act aimed at misleading readers by skilled authors who steal ideas, texts, and graphics and present stolen materials as their own. Its detection is followed by academic sanctions and other punishments. The unintentional form may surface due to incorrectly paraphrasing and referencing previously published works [ 21 ].

Common instances of plagiarism

Inexperienced authors are often blamed for such misconduct, involving unattributed copying of text passages, scientific facts, and others’ ideas. Properly editing and referencing such manuscripts prior to journal submission and correcting erroneous articles by publishing apologies to readers could be sufficient in cases of unintentional plagiarism [ 22 ].

Experts distinguish plagiarism of ideas, words (texts), and images (graphics) [ 3 ]. Ideas can be stolen by unethical evaluators of grant projects, journal manuscripts, or other scholarly materials during the peer review, which is intentionally delayed to allow the plagiarist to publish his/her own article with misappropriated ideas first. Misappropriation of ideas and methodologies is a more serious and inconspicuous misconduct than copying of words [ 23 ].

Textual plagiarism manifests in various forms which can be detected by advanced search engines and software that analyze similarities across a sizeable amount of digitized publications. Direct, or word-for-word, and translational forms of plagiarism are relatively easy to detect by employing search engines and anti-plagiarism software [ 24 , 25 ]. Paraphrasing and patchwork plagiarism may confuse plagiarism detection systems by plagiarists’ attempts to replace a few words in the original text and misappropriate phrases and sentences. Careful manual checks and analyses of keywords and references may help to correctly interpret the similarity reports generated by software.

Plagiarists may intentionally increase the list of references by citing non-existent sources or incorrectly cite primary sources taken from secondary ones (systematic reviews) with the sole aim of misleading readers and concealing plagiarism of secondary publications [ 20 ]. A form of manipulation (“Trojan citation”) is also reported in connection with referring to relevant items to cover up substantive plagiarism and confuse journal editors and anti-plagiarism software [ 26 ].

Current anti-plagiarism software may detect unacknowledged recycled (self-plagiarized) texts, the so-called salami (data stemming from a single study spread across several papers) and augmented (opposite to salami) texts. Accusations of plagiarism in such cases require thorough manual checks of all similar parts, particularly by experts in the professional field.

Detecting identical abstracts requires special consideration due to the similarities of some full texts with congress abstracts and preprints, which are unpublished items and do not account for plagiarism. As such, authors should be advised to provide notes in their manuscripts, linking to previously posted congress abstracts and reposted preprints.

While concentrating on textual similarities, editors employing anti-plagiarism software often overlook graphical overlaps which may reveal compound forms of ethics violation and copyright infringement [ 27 , 28 ]. Thorough graphical analyses are particularly required for manuscripts with tables, figures, depiction of technological processes, and chemical formulae [ 29 ]. Questioning authors about the authenticity of all materials, requesting official reuse permissions from copyright holders, and referencing primary sources of reused or modified graphics may help to avoid unethical conduct and copyright infringement [ 30 ].

With the advent of anti-plagiarism software, some journal editors set limits of minor, moderate, and unacceptable copying and text recycling. They argue that less than 10% of verbatim copying, particularly in Methods section, could be tolerated provided there are no linguistic options to paraphrase [ 31 ]. Accordingly, 15–20% of textual overlap is judged as less tolerable and more than 30% as unacceptable. Although such a quantitative classification helps stratify anti-plagiarism measures, most experts advocate a zero tolerance policy since even a small percentage of copying may reveal complicated and concealed ethics violations [ 32 ].

Plagiarism detection

Researchers should be aware of what constitutes plagiarism and how to detect it ( Table II ). Those authors who master academic English, familiarize themselves with bibliographic searches, and advance their graphics designing skills may avoid most instances of plagiarism, duplication, and copyright infringement. Those who employ anti-plagiarism tools should combine software and human-detection options.

Strategies for plagiarism detection

Although none of the currently available anti-plagiarism systems is perfect [ 33 ], overlooking the importance of related editorial checks may affect the authenticity of scholarly publications and lead to the so-called predatory practices [ 34 , 35 ]. Generally, employing popular online platforms such as Google Scholar, Grammarly, and PlagScan makes it possible to improve the quality of references, readability, and linguistic style of scholarly manuscripts and increase their likelihood of acceptance by influential journals [ 36 ]. The role of processing manuscripts through freely available plagiarism detection tools is difficult to overestimate, since most researchers and faculty members, particularly in developing countries, lack access to proprietary software [ 37 ].

Preliminary evidence suggests that there are differences in the prevalence of textual plagiarism across academic disciplines, necessitating careful checks in science, technology, engineering, and mathematics journal submissions [ 38 ]. Additionally, in the era of digitization and open access, reviews are more likely to contain “copy-and-paste” written sections, pointing to the particular need for checks of this type of article [ 39 ].

Plagiarism detection and verification is largely based on text-matching search engines and computer software that report similarity scores. The advanced software is integrated with numerous publishers and online platforms to allow scanning of potential overlaps among countless open-access and subscription literature items [ 40 ]. Perhaps the most advanced anti-plagiarism system is iThenticate, which is employed by most established publishers to report the overall similarity score and similarity score from a single source [ 41 ]. The system offers options to filter direct quotations, bibliographies, and methodologies to minimize chances of erroneous reports [ 42 ]. High overall similarity scores (>35%) often point to plagiarism requiring outright rejection or retraction [ 43 ].

Regular iThenticate checks have made it possible to minimize, but not exclude, unethical publications [ 44 ]. The reported similarity scores should not replace editorial decisions and should be accompanied by careful reading and validation of references [ 45 ].

Compared to textual similarity detection, image plagiarism detection is a more challenging task, since it often requires both image processing and semantic mapping techniques [ 46 , 47 ]. Google Images is a widely available search engine that can be used to reveal identical or manipulated images processed by Google [ 48 ]. However, this engine fails to detect copied and modified graphical materials. Semantic analyses are particularly useful in such a scenario of image modification. In fact, processing image legends through textual similarity tests may point to misconduct with modified images.

Attempts are underway to propose an advanced system for tracking plagiarism of graphics [ 49 ]. In the meantime, journal editors with a special interest in publishing graphics need to instruct their authors on what constitutes image plagiarism and how to ethically reuse related contents [ 50 ].

Retractions due to plagiarism

Although retractions of published articles are generally not frequent, their analyses may reveal country- and discipline-related differences in editorial strategies, misconduct prevention policies, and enforced measures [ 51 , 52 ]. Examining details of retracted articles which are publicly discussed on the Retraction Watch blog may also prioritize ethics topics for postgraduate education [ 53 , 54 ].

With the widespread use of iThenticate and other plagiarism detection software, numerous related retractions have taken place over the past decade. When retraction notices in PubMed are compared, similar percentages of plagiarism (about 20%) were mentioned in 2008 and 2016 samples [ 55 ]. The number of retractions due to plagiarism varies across countries and academic disciplines, with the U.S., China, Germany, Japan and the U.K. accounting for 3 out of 4 retractions in a sample of 130 surgery articles [ 51 ]. The same study estimated a plagiarism rate of 16% in these articles. Also, an analysis of 176 retractions in obstetrics and gynecology indicated 40 cases of plagiarism (23%) [ 56 ]. In rehabilitation and sport sciences, retractions due to plagiarism were reported in 11 (26%) and 7 (13%) cases, respectively [ 57 ]. And finally, an analysis of 22 rheumatology retractions revealed 7 (32%) cases of plagiarism in review articles [ 58 ].

Conclusions

Plagiarism continues to affect the integrity of scholarly publications worldwide. Digitization and open access provide numerous opportunities for accessing and disseminating scientific information. However, some researchers and authors are tempted to intentionally or unintentionally embark on shortcuts and construct their articles with copied and unattributed texts, graphics, and ideas. Arguably, educating authors how to systematically access and process literature and how to master academic English may prevent most instances of modern-day plagiarism. Systematic searches are necessary for choosing new topics and avoiding redundancies. Processing retrieved articles, appropriately referring to published scientific facts, and writing in one’s own words may further improve the ethical standing of new manuscripts.

Researchers and research managers alike need to learn more about globally acceptable writing practices, regularly analyze retractions due to plagiarism, and avoid related errors in their practice. Knowledge of global editorial guidance and plagiarism detection and prevention strategies is essential for successful writing and targeting influential ethical journals. Journal editors should enforce a “trust, but verify” policy by performing plagiarism checks, inquiring about authors’ writing practices, and asking for disclaimers if suspicion of plagiarism persists.
