While reviewing writing and checking for plagiarism, you may have come across the term, “Similarity Index.”

What’s the similarity index refer to? Is there a difference between similarity and plagiarism? Where does one end and the other begin? 

In this article, we’ll take a closer look at both similarity and plagiarism to help you better understand their key differences, along with plenty of examples to illustrate.

What Is Similarity?

Similar ideas or concepts being shared, especially in specific industries, are commonplace and may not necessarily indicate plagiarism. 

Technical jargon and industry-specific expressions (think expressions like “cutting-edge technology”) are incredibly commonplace and shared across many fields or industries.

Similarity often happens when a discussion on a topic overlaps with existing material

How the similarity index is defined in academic journals

“Similarity and Plagiarism in Scholarly Journal Submissions: Bringing Clarity to the Concept for Authors, Reviewers and Editors,” an article available through the National Library of Medicine, offers the following definition of the similarity index:

the extent of overlap or match between an author's work compared to other existing sources (books, websites, student thesis, and research articles) in the databases of similarity checking tools.” - Similarity and Plagiarism in Scholarly Journal Submissions

So, essentially similarity (or the similarity index) describes when text (such as two different articles, papers, or blog posts on the same topic) overlap in terms of their ideas or concepts. 

Example: In the context of how to solve the issue of plagiarism, two authors may talk about the use of AI to identify instances of plagiarism in a similar way, with research that was conducted independently.

What’s happening is that the two works are likely pulling information from the same studies, articles, or research available, while using similar terms and ideas to reference and cite the material

The similarity index: acceptable similarity levels in journals

Plagiarism detection software may flag similarities based on how much one passage or text matches another existing publication. 

The level or percentage of similarity that’s acceptable in academic work varies. 

For instance, according to “Similarity and Plagiarism in Scholarly Journal Submissions,” some journal editors accept submissions that have 5% (or lower) similarity, while others may turn away submissions with a similarity level above 10%

The key takeaway? The acceptable level of similarity is dependent on the editorial policies of a particular publication

It’s best practice to review publication guidelines before submitting work.

How Do Similarity and Plagiarism Differ?

A look at the definition of plagiarism

In contrast to similarity which describes overlap, plagiarism, is when someone directly copies another person’s work and tries to pass it off or take credit for it as their own original idea.

The above-mentioned journal article defines plagiarism as:

when somebody presents the published or unpublished work of others, including ideas, scholarly text, images, research design and data, as new and original rather than crediting the existing source of it.” - Similarity and Plagiarism in Scholarly Journal Submissions

There are several types of plagiarism, here’s a quick overview of two common kinds of plagiarism:

Direct Plagiarism

Copying and pasting entire sentences, paragraphs, or other sections of text directly from one piece into your own work without proper citation or credit is direct plagiarism

When you reference another author’s work, conclusion, or study, you must cite them and give credit where it’s due (learn more about citation checkers). 

Paraphrasing

Paraphrasing involves swapping out a few words from a source and editing them just slightly so that the quote or reference isn’t a word-for-word copy of the original. In the case of paraphrase plagiarism, the original author or source isn’t acknowledged with proper citations. 

The Originality.ai plagiarism checker is an excellent way to check for more complex kinds of plagiarism like paraphrase plagiarism. 

Plagiarism from a legal or ethical standpoint

Plagiarism holds the potential for legal and ethical implications:

The best practice is to properly cite any sources included in a work.

Similarity vs. plagiarism when it comes to intent

One of the main differences between similarity and plagiarism has to do with intent; in other words, what’s driving the action

Intent in the context of similarity

If two or more people are working on a given topic in a given industry, some overlap may occur. 

The difference? Each person is conducting independent research on a similar topic and providing citations where they reference the research of others. 

Intent in the context of plagiarism

With plagiarism, the intent may be to present the work of another author as theirs without proper credit.

It’s important to note that accidental plagiarism does occur. For instance, a person might forget citations or improperly reference a quote within the text. This is where plagiarism checkers come in especially handy. 

With a plagiarism checker, you can review text and check any highlights to make sure quotes are properly cited before submitting work.

How Are Works Cited if They Deal With Similar Topics?

With plagiarism, the plagiarized work is not correctly cited; that’s one of the factors that makes it plagiarism to begin with. 

Remember, it’s not enough just to change a few words around or sprinkle in a handful of synonyms — you still have to credit the original author

With similarity, works are typically correctly cited. 

Two articles can be about similar topics and even pull the same quotes from researchers and studies or other experts, as long as they’re cited. 

When you correctly reference the author as the origin of a quote, study, or other piece of information you’re including, you help to avoid plagiarism.

Final Thoughts: Similarity vs. Plagiarism

Similarity occurs when two distinct papers or articles cover the same topic. They may reference the same studies, charts, or experts, but the research is independent and cited properly. In short, the similarity is in the data, not the argument or interpretation itself. 

In contrast, plagiarism uses someone else’s work and passes it off as theirs without referencing the original author. It misrepresents the origins of work and can have serious consequences. 

To identify potential instances of plagiarism or quotes that need citations, complement your editing process with a plagiarism checker. Carefully review highlights to ensure that the research conducted for the piece correctly references the original author(s).

Referencing the original author or study helps to avoid and prevent plagiarism and establish credibility as a thought leader in your space.

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.

Why is the English so poor for some prompts?

When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.

Frequently Asked Questions

Why is it important to check for plagiarism?

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.

What is Text Comparison?

Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.

How do Text Comparison Tools Work?

Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.

String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.

The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.

Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.

String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.

What is Syntax Highlighting?

Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.

The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.
