If you’ve ever tried to figure out which journal is the best fit for your research or wondered how journals classification is carried out, you’ve probably come across terms like Quartiles, H-Index, Impact Factor (IF), and Source Normalised Impact per Paper (SNIP). These metrics might sound technical, but they are simply tools to measure how much attention a journal’s research gets. Here’s a straightforward explanation of what they mean and how they work

Quartiles in Journals Classification: Ranking by Performance

The system of dividing journals into four quartiles, Q1, Q2, Q3, and Q4, was created to make it easier to compare their quality and impact within a specific field. This idea became popular through Scopus and Journal Citation Reports (JCR) databases, which rank journals based on metrics like citations. The concept builds on the work of Eugene Garfield, who introduced the Impact Factor, offering a way to see how journals stand up against others. Quartiles break things down further: Q1 represents the top 25% of journals in a category, while Q4 includes those at the lower end. It’s a straightforward way to help researchers determine which journals are most influential in their areas of study.

• Q1: Top 25% of journals in the field (highest-ranked).
• Q2: 25-50% (mid-high-ranked).
• Q3: 50-75% (mid-low-ranked).
• Q4: Bottom 25% (lowest-ranked).

However, not all Q3 or Q4 journals are necessarily a disadvantage. While they may not be as well-known, they are still important in scientific research. Some of the benefits include:

• Affordability: These journals are easier for researchers to access, especially for those on a tight budget.
• Focused Topics: They tend to cover more specific, niche areas of study, making them great for in-depth exploration of certain subjects.
• Great for New Researchers: Q3 and Q4 journals classification can be a good place for new researchers to publish their first paper and gain experience in the publishing world.
• Ideal for Basic Research: They’re a great option for research that focuses on the basics of science

Finally, publishing your article in a Q3 or Q4 journal doesn’t mean it lacks value or won’t make an impact. If your work presents new findings that address a real problem, it can still attract attention, even when published in a lower-ranked journal.

H-Index: A Balance of Quantity and Quality

The H-Index score is an important factor in journal classification. It looks at the number of articles a journal has published and how often those articles are cited. It balances quantity (how many articles a journal publishes) with quality (how many of its articles are referenced).

For example, if a journal has an H-Index of 15, it means it has published 15 articles, each cited at least 15 times. It’s a simple way to measure a journal’s influence without focusing too much on just one super-cited article or a bunch of rarely cited ones.

How H-index works:

Let’s say a journal has published 4 articles, and the number of citations for each article looks like this:

• The 1st article has 10 citations – exceeds 1 citation.
• The 2nd article has 24 citations – exceeds 2 citations.
• The 3rd article has 5 citations – exceeds 3 citations.
• The 4th article falls short of 4 citations.

In this case, the journal has three articles that each have at least three citations. The fourth article doesn’t hit the mark, so the H-index stops at 3.

This metric can help researchers, professionals, and institutions decide if a journal publishes research that gets noticed and cited by the academic community. It’s not the full picture, but it’s a useful starting point for understanding the journal’s influence.

Impact Factor: Citation Average

The Impact Factor (IF) is a number that shows how often a journal’s articles are cited on average over the past two years. It helps you understand how much attention the journal’s research gets from other scholars and it also helps with journals classification.

How it works?

To calculate the IF, look at how many times articles from a journal were cited in the past two years. Then, you divide that by the total number of articles the journal published in those two years. This gives you an average citation count per article. 

Example:

Let’s say we want to figure out the IF for Journal A in 2023:

1. In 2021 and 2022, Journal A published 50 articles.  

2. In 2023, those articles were cited 200 times in total.  

3. You take the total citations (200) and divide it by the total number of articles (50):  

200 ÷ 50 = 4

So, Journal A has an Impact Factor of 4, meaning its articles were cited, on average, four times each. A higher Impact Factor often places journals higher in classification, but keep in mind that it’s not the full story. Some specialised journals may have lower Impact Factors even though they’re highly respected in their niche.

SNIP: Fair Comparisons Across Fields

SNIP (Source Normalised Impact per Paper) is a valuable metric in journals classification because it goes one step further. It measures contextual citation impact and takes into account the fact that different research fields have different citation habits. For instance, medical papers often get cited a lot, while mathematics papers don’t, even if they’re equally important in their fields.

SNIP adjusts the average citations a journal receives based on these differences, making it easier to compare journals across disciplines.

Example:

• Journal A publishes in a low-citation field like social sciences and averages 3 citations per article. Adjusted for its field, its SNIP might be 1.6.
• Journal B publishes in a high-citation field like biomedicine and has an average of 8 citations per article. After adjustment, its SNIP might be 1.2.

SNIP makes sure journals in fields with fewer citations still get the recognition they deserve.

What it tells you:

SNIP is especially useful for journal classification because it levels the playing field between disciplines. A higher SNIP score suggests that a journal’s articles are cited more often than expected for its field. It’s a helpful tool for comparing journals, but it’s just one of many ways to evaluate a journal’s influence or importance.

Conclusion 

Metrics like Quartiles, H-Index, Impact Factor, and SNIP are essential tools for journals classification, helping researchers, librarians, and institutions rank journals and understand their influence. Each metric focuses on a different aspect of a journal’s impact.  

But no single number can tell the whole story. A journal might excel in one metric but be less prominent in another, or it might be vital to a specific audience despite modest scores. These tools are helpful guides, but the best journal for your research depends on your goals.

The rise of predatory journals began around the time open-access journals became popular. While open-access journals typically charge authors a fee to cover publishing costs, predatory journals exploit this by tricking researchers into paying for publication in a journal that doesn’t actually provide the benefits of expert peer-reviewed or academic value that a legitimate journal would.

What Are Predatory Journals?  

Predatory publishing, carried out by predatory journals, refers to deceptive practices by fake journals created solely for profit. These journals often lack scientific value and do not follow any ethical considerations in academic research or rigorous peer review standards. As a result, their acceptance rates for submitted research are high, primarily because their goal is to make money, not advance academic knowledge.

Who Are the Targets?

• Researchers From Developing Institutions

Those from less well-established institutions or countries where access to quality academic publishing opportunities is limited. These researchers may not have the experience or support to differentiate between legitimate and predatory outlets    

• Early-career researchers, graduate students, and those under pressure to publish quickly

These individuals, eager to disseminate their work, fall into the “pay and get published” trap. After paying the fees, they receive an acceptance letter within days and see their work published without proper peer review, which often damages their credibility.  

What Happens if You Publish in a Predatory Journal?  

It’s essential for researchers to carefully evaluate the journals they consider for submitting their work. Predatory journals create the illusion of being reputable and indexed in trusted databases when in reality, they are not.

Publishing in these journals, especially without realising their nature, can be a serious pitfall. Such publications offer no meaningful academic value and can significantly harm a researcher’s reputation. It is a total waste of time, effort and money. 

How to Spot Predatory Journals  

In the following points, we’ll explore the characteristics of predatory journals and how to distinguish them from legitimate ones. We’ll also discuss ways to verify journals and identify the predatory ones.

As mentioned earlier, predatory journals use several deceptive tactics. Some of the key signs to look for include:

• Their names could be similar to one of the top academic journals.
• Their publishing policies, evaluation standards, and editorial board details are unclear or vague.
• They tend to display fake impact factors (IF).
• They typically charge high publication fees.
• They often have unusually high acceptance rates for submitted research.
• Most have rapid publication processes, often completed in just days or weeks.
• They could be indexed in fake or unreliable databases.
• They often send unsolicited marketing emails urging researchers to submit their work, promising quick publication.

Ways to Verify the Credibility of a Journal:  

To safeguard your work, follow these tips:  

• Check Trusted Databases

Look up the journal in reputable databases like Zendy or Web of Science. These platforms can help you verify the journal’s indexing and journals classification, giving you a sense of its academic performance.

• Use Beall’s List

Visit beallslist.net, you will see a list of predatory journals, search for the journal or its publisher. Beall’s list provides insights into potentially predatory journals and publishers, helping you identify any red flags.

• Use Think, Check, Submit Tools

Utilise the tools provided by Think, Check, Submit. This resource offers a step-by-step guide to evaluate journals, making it easier to decide where to publish your research.

• Take a Thorough Approach

It’s essential to use multiple tools and methods rather than relying on a single one. None of these methods provide a definitive judgment on a journal’s credibility, but together they give a clearer picture. Always take the time to research thoroughly before submitting your work.

• Consult University Resources: 

Academic institutions often provide curated lists of trusted journals and warnings about predatory journals.  

Are All Open-Access Journals Predatory?

No, not all Open Access (OA) journals are predatory. Open Access is a publishing model designed to make scholarly research freely available to the public, promoting knowledge sharing and accessibility. Unfortunately, the model can sometimes be exploited by predatory journals that prioritise profit over academic integrity.

Conclusion 

Staying cautious is key to avoiding the risks associated with predatory journals, and preserving academic integrity. Take the time to verify journal legitimacy, and rely on trusted databases and resources to ensure your work is published in a credible platform that aligns with your academic goals.
