How does PLAG compare with other plagiarism checkers

All similarities	Copy & Paste	Real-time	Rewrite		Sources
			Human	ChatGPT	Scholarly	Picture based
★★★★★	★★★★★	★★★★★	★★★★★	★★★★★	★★★★★	★★★★★

Quality of plagiarism detection

PLAG performed the best in detecting various types of plagiarism, such as copy&paste and paraphrasing.

PLAG also was capable to detect scholarly content and texts from picture-based sources. The “picture” test, as we call it, was the hardest one and PLAG was one of only three plagiarism checkers who passed it.

ChatGPT rewrite detection scored 36 out of 100 but still, it was the highest result among other plagiarism checkers.

Usability

PLAG scored high in the usability test, however, the score was not the highest.

PLAG has developed good UX/UI. The report is clear to understand and to work with, but there is a low level of interactivity with the report – no possibility to eliminate sources or make comments.

The document was checked in 2min 58s, which is a moderate result.

PLAG also offers additional services such as document editing, proofreading, and plagiarism removal service, that are useful to students. Our total paid sum for testing with PLAG came at 18,85 euros. Not the best deal price-wise. However, in our research, we haven‘t found any other tool, that could match the quality of this plag checker.

Trustworthiness

PLAG is registered in the EU and it explicitly stated in their privacy policy that they do not include user documents in their comparative database, nor sell papers.

A very good thing about PLAG is that, unlike most plagiarism checkers, it allows checking documents free of charge. This is a good way to test the service prior to paying money. However, the free option gives only a limited amount of scores. The detailed report is a paid option.

Copyleaks performed relatively poorly with different source types. It was good to detect Copy & Paste plagiarism but didn’t perform well with both rewrite tests.

Copyleaks was not able to detect picture-based sources and detection of scholarly content was limited.

Usability

Copyleaks online report is interactive. It is possible to exclude sources and also compare the original document with the source side by side.

Still, the report is quite difficult to read as they highlight all the sources with the same color.

The online report did not maintain the layout of the original file, and this makes it a bit more challenging to work with a tool.

How does Plagium compare with other plagiarism checkers

All similarities	Copy & Paste	Real-time	Rewrite		Sources
			Human	ChatGPT	Scholarly	Picture based
★★★☆☆	★★★★★	★★★★★	★★★★★	★★★★★	★★★☆☆	☆☆☆☆☆

Quality of detection

Overall Plagium detection score was mediocre. Although Plagium showed good results in detecting copy&paste plagiarism and rewrites, it was not so good at the detection of scholarly sources. This makes this tool less useful for students.

Plagium scored zero on the detection of picture-based sources.

Usability

It seems that Plagium has a sentence-based approach to identifying plagiarism. This might help to deliver faster results (the report came just after 1 min 32 s), but it prevents Plagium from delivering the detailed report.

It was not possible to see which words of the sentence were rewritten. It was also not possible to see how much of the text was taken from one source and which sentences belong to that source.

Trustworthiness

Plagium seems to be a trustworthy service. It is registered in the US and it seems that they are not affiliated with any paper mill.

Plagium does not offer a free trial, so it is not possible to check the service without risking your money.

ChatGPT: dos and don’ts for students

July 25, 2023August 21, 2023

Artificial intelligence (AI) is rapidly developing in various areas of life, including education. The ChatGPT tool is widely used among students to help them inspire, create, test, or modify content in various forms from text to images, audio, and more. So what is ChatGPT, and what is the power of its emergence in today’s student life?

ChatGPT in the academic arena

In the past two decades, AI has seamlessly woven into our daily tools, with ChatGPT emerging as a prominent example. This chatbot offers varied assistance, from information sourcing to student aid, but its academic efficacy has shown mixed results. Dive with us into its journey, capabilities, and performance insights, which we discuss briefly.

Evolution

Today ChatGPT is a hot topic. AI-mediated and has been ongoing for the last 20 years without us even noticing this (Google, Google Scholar, social media channels, Netflix, Amazon, etc.). A significant jump in functionality, growing amounts of data, and the power of technology to do the work involved have contributed to the fact that eight of the top ten organizations in the world are involved in AI.

Capabilities

ChatGPT is a chatbot designed to assist with various tasks using textual information and a model of dialogue between the end user and the device. It can provide detailed information, write blocks of text, and provide quick answers, which saves a lot of time. An AI-powered chatbot can help students write university assignments, prepare for exams, and translate or summarize information. However, this may be considered cheating by academic institutions.

Performance insights

Research shows that results on ChatGPT exams vary by subject. The researchers found that he excelled on microbiology quizzes, but he was at the bottom of the final exams at the University of Minnesota Law School. A study of educational institutions around the world found that accountancy students outperformed a chatbot in accountancy exams, despite it outperforming multiple-choice questions.

Benefits of using ChatGPT

It is a handy tool as over time can produce personalized guidance for students based on their ongoing performance and contribute to the improvement of their academic achievements.

ChatGPT is available 24/7.
Helps you learn more effectively by providing access to a wide variety of resources (study materials, articles, practice exams, etc.).
This improves a person’s study skills, effective time management, and workload.
Increases motivation and engagement in the learning process by providing appropriate support and personal guidance.

For what purposes should learners use ChatGPT?

Brainstorm. A chatbot can prompt and provide ideas for writing assignments, but the rest of the work must be done by the student. Disclosure may be required by the University.
Ask for advice. Offers guidance on essay writing and research presentation. Some universities allow you to use this tool to overcome the hurdle.
Explain the material. A helpful tool for students to help them understand the material presented on a specific topic or concept, or to clarify questions that have arisen. It provides quick answers and explanations that make learning more engaging. In a sense, it becomes a personal virtual teacher, closing the gap between student and teacher.
Get feedback. Provides comments and suggestions but treats responses carefully as they may lack a deep understanding of the topic. An AI tool should supplement, but not replace, human feedback on structure.
Proofreading. Correct grammatical errors by phrasing or paraphrasing text, sentence structure, and maintaining coherence.
Learn a new language. Offers translations, word definitions, examples, form practice exercises, and chat support.

How ChatGPT impacts student learning and achievement

Machine-driven algorithms are revolutionizing the education sector, but there are questions as to whether the aid received violates ethical standards and relevant guidelines. Let’s explore how artificial intelligence technology is changing the way students learn and achieve.

Used to write essays and assignments. ChatGPT can help with ideas but should not be used to ask for detailed evaluations – this is considered plagiarism. Teachers may notice robot models and lack of style, emotion, and most importantly, human creativity.
Restrictions apply. Used beyond the set permitted areas and boundaries. Limitations may apply to specific topics or just parts of them. If there is a lack of instruction or if in doubt, advice is to always check with responsible people.
Too much faith in technology. This prevents learners from thinking independently, creating ideas and solutions, and critically evaluating situations and information, which can lead to passive learning.
Blindly trusted. The information may not always be accurate, so it should not be blindly relied upon – this is acknowledged by its developers, OpenAI. This tool is not designed specifically for learning-based content, and information is based on 2021 learning data. Also, it is not good at finding live sources and can present fake sources as real.

Other interesting facts

The current chatbot is trained on 175 billion parameters. The next ChatGPT model will be trained on one trillion parameters, with the advent of which it is hoped to bridge the gap between technology and human performance. So now is the time to start researching and learning how to effectively use this text content generator for maximum results.
When creating content using AI tools for ratings, they should be cited as the source of the information and cited accordingly. On the other hand, violation of the institution’s policy may result in negative evaluations or termination of study contracts.
Currently, different universities have different approaches and policies regarding the use of artificial intelligence, ranging from outright bans to recognition as a valuable resource. Learners should review institutional guidelines and requirements before employing them for specific assignments. As technology advances, the rules in this area are also constantly changing.
Ethical and conscious application of AI tools, reinforced by critical thinking, assessment of reliability, accuracy, and similar parameters, will provide appropriate support and yield valuable results.
The age of algorithms we live in will not change or otherwise disappear. An AI-powered future is on our doorstep, offering unlimited potential in the education sector, but also the potential dangers of increasing reliance on such tools and inhibiting their impact on learning. Professional bodies must monitor such changes, act and adapt accordingly.

Conclusion

In the AI-dominated era, ChatGPT stands out as a powerful academic tool, providing different types of help from content creation to language learning. Yet, its rise poses challenges, especially concerning plagiarism and over-dependence. As these tools advance, it’s essential for educators and students to understand their benefits and limits responsibly, ensuring that technology supports, them instead of getting in the way of real learning.

How do plagiarism checkers detect paraphrasing?

June 12, 2014August 28, 2023

Plagiarism involves taking credit for someone else’s ideas, words, or images, a practice considered unethical in academic and professional environments. It can go unnoticed by students who may accidentally rephrase someone else’s words without proper attribution. Since quotation marks are not used when something is paraphrased, it can easily escape the grasp of a proofreader and go on into the final draft. However, it is not entirely unachievable, especially since plagiarism checkers detect paraphrasing more efficiently nowadays.

Detecting paraphrasing can be a challenging task, as it involves identifying similarities and differences between texts. In the subsequent sections, we will delve into a comprehensive discussion about common methods and techniques employed to discern instances of paraphrasing.

How do plagiarism checkers detect paraphrasing: Suitable methods explored

In today’s educational landscape, plagiarism checkers have become increasingly advanced, going beyond only flagging copied text to also detecting paraphrased content. This article explores the methods allowing these tools to effectively identify paraphrasing.

1. String matching

This method involves comparing texts at the character or word level to pinpoint exact matches. A high degree of similarity in character sequences or word choices between two texts could signal paraphrasing. These tools employ complex algorithms that can even consider the contextual meaning of words, making it increasingly difficult for plagiarized, paraphrased material to go undetected.

2. Cosine similarity

Cosine similarity is one of the methods by which plagiarism checkers detect paraphrasing. It measures the similarity between two texts based on the angle between their vector representations in a high-dimensional space. By representing texts as vectors of word frequencies or embeddings, these tools can compute the cosine similarity score to further refine their ability to detect paraphrased content.

3. Word alignment models

These models align words or phrases between two texts to identify their correspondences. By comparing the aligned segments, you can detect paraphrasing based on similarities and differences in the matched sequences.

4. Semantic analysis

This approach involves analyzing the meaning and context of words and phrases in texts. Techniques like latent semantic analysis (LSA), word embeddings (such as Word2Vec or GloVe), or deep learning models like BERT can capture semantic relationships between words and identify paraphrasing based on the similarity of their semantic representations.

5. Machine learning

Supervised machine learning algorithms can be trained on labeled datasets of paraphrased and non-paraphrased pairs of texts. These models can learn patterns and features that distinguish paraphrases and can be used to classify new instances of text as paraphrased or not.

6. N-gram analysis

N-grams are groups of words that are right next to each other. When you check how often these groups appear in different texts and compare them, you can find similar phrases or sequences. If there are many similar patterns, it could mean that the text might have been paraphrased.

7. Near duplicate detection

The last way that plagiarism checkers detect paraphrasing effectively.

Near-duplicate detection algorithms are frequently employed in paraphrasing detection to pinpoint text segments that display a high degree of similarity or are almost identical. These algorithms are specifically crafted to recognize paraphrased content through the comparison of text similarity on a detailed level.

Which method is usually used by plagiarism prevention software?

Technological solutions utilized by professional plagiarism prevention services typically rely on n-gram analysis. By leveraging n-gram-based technology, these services achieve a remarkably high precision rate. This is one of the best ways plagiarism checkers detect paraphrasing, enabling the identification and highlighting of exact words that have been rewritten.

Mechanics of how plagiarism checkers detect paraphrasing

Plagiarism prevention services commonly employ the fingerprinting technique to compare documents. This involves extracting the necessary n-grams from the documents to be verified and comparing them with the n-grams of all documents in their databases.

Example

Let’s say there is a sentence: « Le mont Olympe est la plus haute montagne de Grèce. »

The n-grams (for instance 3-grams) of this sentence will be:

Le mont Olympe
mont Olympe est
Olympe est la
est la plus
la plus haute
plus haute montagne
haute montagne de
montagne de Grèce

Case 1. Replacement

If the word is replaced by the other word, still some of the n-grams match and it is possible to detect the word replacement by further analysis.

Changed sentence: « Le montagne Olympe est la plus haute montagne de Péloponnèse. »

Original 3-grams	3-grams of changed text
Le mont Olympe mont Olympe est Olympe est la est la plus la plus haute plus haute montagne haute montagne de montagne de Grèce	Le *montagne* Olympe *montagne* Olympe est Olympe est la est la plus la plus haute plus haute montagne haute montagne de Montagne de *Péloponnèse*

Case 2. Changed the ordering of words (or sentences, paragraphs)

When the order of the sentence is changed, still some 3-grams match so it is possible to detect the change.

Changed sentence: « La plus haute montagne de Grèce est Le mont Olympe. »

Original 3-grams	3-grams of changed text
Le mont Olympe mont Olympe est Olympe est la est la plus la plus haute plus haute montagne haute montagne de montagne de Grèce	La plus haute plus haute montagne haute montagne de montagne de Grèce de Grèce est Grèce est Le est Le mont Le mont Olympe

Case 3. Added new words

When the new words are added, there are still some 3-grams that match so it is possible to detect the change.

Changed sentence: « Le mont Olympe est de loin la plus haute montagne de Grèce. »

Original 3-grams	3-grams of changed text
Le mont Olympe mont Olympe est Olympe est la est la plus la plus haute plus haute montagne haute montagne de montagne de Grèce	Le mont Olympe mont Olympe est Olympe est de est de loin de loin la loin la plus la plus haute plus haute montagne haute montagne de montagne de Grèce

Case 4. Deleted some words

When the word is removed, there are still some 3-grams that match so it is possible to detect the change.

Changed sentence: « L’Olympe est la plus haute montagne de Grèce. »

Original 3-grams	3-grams of changed text
Le mont Olympe mont Olympe est Olympe est la est la plus la plus haute plus haute montagne haute montagne de montagne de Grèce	L’Olympe est la est la plus la plus haute plus haute montagne haute montagne de montagne de Grèce

Real-world example

Upon completion of verification in an actual document, paraphrased sections are often identified through interrupted markings. These interruptions, denoting changed words, are highlighted to enhance visibility and distinction.

Below, you will find an example of an actual document.

The first excerpt comes from a file that has been verified using the OXSICO plagiarism prevention service:

The second excerpt is from the original source document:

After a deeper analysis it is evident that the selected part of the document was paraphrased by making the following changes:

Original text	Paraphrased text	Changes
supports innovation is also characterized	backs up innovation is besides defined	Replacement
economic and social knowledge, efficient systems	economical and societal awareness, efficient organization	Replacement
proposals (ideas)	recommendation	Replacement, deletion
attitudes	postures	Replacement
success	winner	Replacement
process (Perenc, Holub-Ivan	cognitive process (Perenc, Holub – Ivan	Addition
pro-innovation	favorable	Replacement
creating a climate	: creating a condition	Replacement
favorable	prosperous	Replacement
developing knowledge	development awareness	Replacement

Conclusion

Plagiarism, frequently undetected in cases of paraphrasing, remains a significant concern in academia. Technological advances have equipped plagiarism checkers with the ability to effectively identify paraphrased content. Specifically, plagiarism checkers detect paraphrasing through various methods like string matching, cosine similarity, and n-gram analysis. Notably, n-gram analysis stands out for its high precision rate. These advancements substantially reduce the likelihood of plagiarized and paraphrased material going undetected, thereby enhancing academic integrity.

Avoiding copy-paste plagiarism

May 28, 2014August 25, 2023

Anyone who has reached school age should be aware that copying someone else’s work and claiming it as one’s own is unethical. In writing, this specific form is known as copy-paste plagiarism, and it has become increasingly common in the age of digital information. With a wealth of pre-written articles readily available on the internet, students are submitting to this form of plagiarism either due to a misunderstanding of copyright laws or simple laziness, seeking quick ways to obtain content.

This article aims to clarify the concept of copy-paste plagiarism, offer ethical alternatives for content creation, and provide insights into responsible citation and quoting practices.

Explanation of copy-paste plagiarism

With one research window and one word-processing window open on your computer screen, the attraction to copy-paste text from an existing work into your new project is often hard to resist. This practice, known as copy-paste plagiarism, typically doesn’t involve copying an entire document. Rather, bits and pieces from different articles may be copied and integrated into your own writing. However, such actions come with significant risks.

Whether you copy an entire piece or just a few sentences, such actions are easily detectable with the best plagiarism checker programs. The consequences go beyond academic penalties for cheating. You’re also violating copyright law, which can result in legal repercussions, including potential lawsuits from the original author or the rights holder of the piece.

Any time you utilize someone else’s work as your own, you are violating copyright law and committing plagiarism. This could result not only in academic penalties for cheating but also in legal consequences, including potential lawsuits from the original author or the rights holder of the piece.

Ethical alternatives to copy-paste plagiarism

Before diving into the complexities of avoiding copy-paste plagiarism, it’s essential to recognize that there are ethical and practical alternatives. Whether you’re a student, researcher, or professional, understanding how to properly paraphrase, quote, and credit others’ work is vital for maintaining integrity in your writing. Below are some specific strategies to consider.

What to do besides plagiarize

Always write things in your own words, but simply reading a sentence and rewriting it with a few synonyms or changes in word order is not enough. This is so close to copy-paste plagiarism that it could be considered almost the same thing. These rephrased sentences can also be flagged by modern plagiarism checker programs.

Instead of copying work, you have two options

Navigating the world of academic and professional writing involves more than just putting words on a page; it also requires following to ethical standards. When you’re incorporating someone else’s work or ideas into your own, it’s crucial to do so responsibly. Below are two primary approaches to ensure you maintain integrity in your writing.

The first option is usually the best: Original research and composition

Gather information. Use multiple, credible sources to collect data or insights.
Take notes. Document key points, statistics, or quotes that you may use.
Understand the topic. Ensure you have a thorough understanding of what you’re writing about.
Formulate a thesis. Develop a unique approach or argument for your work.
Outline. Create an outline to organize your thoughts and guide your writing process.
Write. Start writing your work while keeping your notes nearby to look at, but without copying text directly from sources.

The second option: Cititing others’ work

Quotation marks. If you must use someone else’s work word-for-word, enclose the text in quotation marks.
Credit the source. Provide a correct citation to give proper credit to the original author or copyright holder.

By following these guidelines, you can avoid the challenge of copy-paste plagiarism while also producing a high-quality, original piece of work.

A brief guide to ethical quoting and citing in academic writing

Navigating the complexities of academic writing means knowing how to incorporate quotes without crossing into plagiarism. Whether you’re adhering to school guidelines or aiming for ethical writing, proper citation is crucial. Here’s a brief guide to help you quote responsibly:

Check school guidelines. Always review your institution’s rules on quoting text. Excessive quoting, even if correctly cited, might suggest inadequate original contribution.
Use quotation marks. Enclose any borrowed phrase, sentence, or group of sentences in quotation marks.
Attribute properly. Clearly indicate the original writer. Generally, providing the writer’s name and date is sufficient.
Include source name. If the text is from a book or other publication, mention the source alongside the author.

Conclusion

As people get busier, perhaps lazier, and have more access through the internet to written articles, ebooks, and reports, the incidents of copy-paste plagiarism are increasing. Avoid trouble, poor grades, and possible legal charges by learning to research well, put things in your own words, and cite quotations when necessary.

Examples of plagiarism: How to easily notice and remove

May 14, 2014August 30, 2023

Plagiarism comes in plenty of forms. Whether it is intentional or not, it can easily be spotted if someone knows what to look for. In this article, we will introduce you to the four most common plagiarism examples. We hope that these examples of plagiarism will help you to correct your paper quickly and easily.

4 prevalent examples of plagiarism in scholarly work

Having introduced the general landscape of plagiarism, let’s identify our focus on scholarly contexts. Academic and research environments have strict norms concerning intellectual honesty and ethics. To navigate these norms effectively, it’s crucial to recognize examples of plagiarism and understand their nuances. Below, we provide a detailed review of four prevalent examples of plagiarism commonly found in academic writing.

1. Direct quotation

The first type of plagiarism is direct quotation without giving proper credit, which serves as one of the clearer examples of plagiarism. All authors have their strengths and weaknesses. However, taking credit for someone else’s strength won’t contribute to your own skills or knowledge.

Key points to consider:

Using phrases or sentences from an original source and adding them to your work constitutes this type of plagiarism if not properly cited.
Plagiarism is often easily detected through specialized plagiarism-checking software or in settings where multiple individuals are using the same sources.

To avoid becoming an example of this form of plagiarism, it’s essential to give proper credit when including direct quotations in your assignments or publications.

2. Reworking the wording

The second type, which serves as a sneaky example of plagiarism, involves slightly reworking the wording of an original source without providing proper credit. While the text may appear different on a quick look, taking a closer look reveals a strong similarity to the original content. This form involves the use of phrases or sentences that have been slightly changed but not given proper credit to the original source. No matter how much the text is changed, not giving proper credit is a definite violation and qualifies as plagiarism.

3. Paraphrasing

A third way plagiarism takes place is a paraphrase that copies the layout of the original text. Even if the original author uses words like “morose”, “disgusting”, and “rude” and the rewrite uses “cross”, “yucky”, and “impolite”, if they are used in the same order, it could lead to plagiarism – whether the author of the new piece intended to do so or not. A paraphrase does not mean simply choosing new words and keeping the order and main ideas the same. It’s more than that; it means taking the information and reprocessing and reusing it to create a new main idea and a new order of information.

4. No citation

Another form of plagiarism appears at the end of a paper when no works are cited. These are just examples of plagiarism, but they can significantly affect one’s credibility and integrity. Even if only the general idea is borrowed from a source—perhaps a complete paper on the topic from a different perspective—with just a few small paraphrases that carry little likeness to the original, proper citation is still needed. Footnotes are another effective way to prevent plagiarism, but failing to name the sources in them can also result in plagiarism.

Although these are just some of the more common examples of plagiarism, they can significantly damage a career, whether in academia or in a professional setting. You may want to look at other resources here.

Conclusion

In both academic and professional settings, keeping the integrity of your work is critical. This article provides four widespread examples of plagiarism, from direct quotations to paraphrasing without proper attribution. Understanding these aspects is not just sensible—it’s essential, given the severe consequences for your career. Let this article serve as a brief guide to preserving the honesty of your scholarly and professional writing.
