A journal has an impact factor of about 7.5, can it be considered a top journal?
Relevant answer
Answer
A journal with an impact factor of 7.5 can generally be considered a reputable and high-quality journal, but whether it is classified as a "top" journal depends on the specific field of study. In many disciplines, an impact factor of 7.5 is strong and indicates that the journal is influential within its area, but top-tier journals typically have impact factors that are higher, often in the range of 10 or more, especially in competitive fields like medicine, biology, or physics. However, it's important to consider other factors like the journal's reputation, editorial board, peer-review process, and relevance to your research area when determining its standing.

A journal has an impact factor of about 7.5, can it be considered a top journal?
Relevant answer
Answer
The top journal (by impact factor) in Chemistry has an impact factor over 52 (but that’s a review journal — the top non-review journal has an impact factor of 30), the top journal in Medicine has an impact factor over 32, the top non-review journal in Mathematics has an impact factor just under 5, as does the top non-review journal in Marine and Freshwater Biology, and the top journal in Psychology and Psycholanalysis has an impact factor of just 0.8.
Impact factors also change over time as different topics become “hot” and as citation practices change.
In any field, an impact factor of 7.5 would be considered very respectable.

Correlation between the CiteScore and Journal Impact Factor
Relevant answer
Answer
Elsevier’s Scopus CiteScore may be a practically more useful journal-based metric than Clarivate Analytics’ Journal Impact Factor (JIF) because it is open and transparent about the background data used to derive the metric and because it confers a metric to Scopus-indexed journals that do not carry a JIF. In this study, we wanted to assess whether the CiteScore and JIF of library and information science (LIS) journals was in any way correlated. Drawing on a sample of 212 LIS journals indexed in Scopus and carrying a CiteScore, the top quartile was compared with 43 top-ranking JIF-carrying LIS journals. The average CiteScore (3.27) of the 43 LIS journals was higher than their average JIF (2.425), indicating different citation patterns in Scopus and Web of Science, respectively. Their CiteScore and JIF showed a strong significant positive correlation (r = 0.787; rs = 0.828). The relationship between CiteScore and JIF is valid between 42.6 and 68.6% of all 43 top-ranked LIS journals.see;

Question
1 answer
Generally, most of the journals use these two figures (A) and (B) to calculate the Impact Factor. Let us calculate the Impact Factor for a particular journal for the year 2023.
Impact Factor(IF-2023) = A/B
A -> The number of times that all items published in that journal in 2021 and 2022 were cited by indexed publications during 2023.
B -> The total number of “citable items” published by that journal in 2021 and 2022.
For Example,
A = 1298 (Number of times that all items published in that journal in 2021 and 2022)
B = 541 (The total number of “citable items” published by that journal in 2021 and 2022)
Then the Impact factor of the Journal should be (1298/541)= 2.40 IF.

Answer
Journals will only have a genuine impact factor if they are indexed in Web of Science core collection (SCIE, SSCI, AHCI or ESCI), all managed by Clarivate, which can be checked here https://mjl.clarivate.com/home
Take for example the journal you published in Reptiles & Amphibians (ISSN 2332-4961) https://journals.ku.edu/reptilesandamphibians/about If you insert the ISSN number in the search box here https://mjl.clarivate.com/home there are no hits so no impact factor.
If you click on the boxes on the left, it shows that it is indexed in the following WoS indexes Biological Abstracts, BIOSIS Previews and Zoological Record.

Now, Taiz University attempts to formulate new rules regulating the academic promotions for faculty members. That is challenging and courageous effort made by the academic council to raise our university ranking. However, there are still fluctuations and misunderstanding of some of these rules, e.g., misestimating the effort devoted by a researcher who write and publish a review/mini-review paper. While simple practical articles published in local universities’ journals (all without any impact factors and some with no ISSN yet) are strongly accepted for the academic promotions, the review/mini-review articles are not even if published in ISI journals of good impact factor and mention. So, answering the aforementioned question may assist the academic council to make a proper decision for sake of enhancing the international ranking of our university.

The question, "How can the impact of an article be accurately assessed beyond citation counts or journal impact factors?", challenges the reliance on traditional metrics, like citation counts or journal impact factors (JIF), as the primary indicators of an article's value or influence. It invites a discussion on alternative ways to evaluate an article's true impact in a broader and more meaningful context.
Relevant answer
Answer
I totally agree with the point by Dr Wolfgang R. Dick that metrics like those used are somewhat unhelpful. I say that from the point of view that my articles that got the most interest (with people calling me by telephone or emailing me) actually never got cited.
In fact, one of my project ideas currently will end up being used for reference ranges in some places after I publish that info for a journal article but will probably not ever get any citations in other journal articles. I do not think it should stop me from carrying out this research.

I checked your list and found the following:
Journal of Advanced Biotechnology and Experimental Therapeutics https://www.bsmiab.org/jabet has no impact factor (since it is not indexed in one of Clarivate’s indices which can be as indicated by Jürgen Weippert checked here https://mjl.clarivate.com/home ) but is indexed in Scopus https://www.scopus.com/sourceid/21101023926 and is a member of DOAJ https://doaj.org/toc/2616-4760?source=%7B%22query%22%3A%7B%22bool%22%3A%7B%22must%22%3A%5B%7B%22terms%22%3A%7B%22index.issn.exact%22%3A%5B%222616-4760%22%5D%7D%7D%5D%7D%7D%2C%22size%22%3A100%2C%22sort
The Journal of Phytopharmacology https://www.phytopharmajournal.com mentions in their indexing info no misleading metrics (https://beallslist.net/misleading-metrics/ ) which is a good sign. Their NAAS indexing is comforting as well since it is a reasonably reliable indexing (https://naas.org.in/NJS/journals2024.pdf )
International Journal of Agriculture and Environmental Research https://ijaer.in is unfortunately mentioned in the stand-alone version of the Beall’s list (https://beallslist.net/standalone-journals/ ) and their indexing info is full of so-called misleading metrics (https://beallslist.net/misleading-metrics/ ), most likely a predatory journal

Dear Yassine Messaoud,
There are very many journal impact factors (at least 35). The most recent figures available are, of course, those for 2023 (the 2024 figures won't be available until mid-2025).
What most people mean by journal impact factor is the JIF produced by Clarivate Analytics based on the Web of Science database. You can get the JIF values from Clarivate but I'll attach here an Excel list (the 2023 values) and a pdf (the 2022 values).
CiteScore is a journal impact factor produced by Elsevier and based on the Scopus database. CiteScore values are at https://www.scopus.com/sources. Also based on the Scopus database but calculated differently are the impact factors on the site www.scimagojr.com. These are the Scimago journal importance indices.)
The different journal impact factors do not always correlated and it is never wise to base choice of a journal on only one impact factor.

Answer
The h-index does not depend on the impact factors of the journals in which you published. An h-index of 3 means that you have 3 papers with at least 3 citations. To increase the h-index by 1, you have to have 4 papers with at least 4 citations. You published several papers in 2024, and these will be cited in the course of next years. Please note also that very often the list of citations found by ResearchGate's automated algorithm is incomplete.

Guys here is partial list of JCR (Web of Science) Impact Factor.
Title: Factors Contributing to the Decline of Journal Impact Factors
Abstract: The Journal Citation Reports (JCR) Impact Factor is a widely recognized metric used to evaluate the influence and prestige of scientific journals. However, in recent years, there has been a noticeable decline in the impact factors of many journals indexed in the Web of Science’s JCR database. Causes can be
  1. Evolving Publication Landscape: The scientific publishing landscape has undergone significant transformations in recent years. The rise of open access publishing, preprint servers, and alternative metrics has led to a diversification of research dissemination channels. As a result, traditional subscription-based journals may face increased competition, leading to a redistribution of citations across different platforms.
  2. Field-Specific Trends: Impact factors can vary significantly across different scientific disciplines due to variations in publication practices, citation patterns, and research culture. Changes in funding priorities or emerging research areas may result in shifts in citation patterns, impacting the impact factors of certain journals.
  3. Quality vs. Quantity: The pressure to publish more articles within shorter timeframes can lead to an increase in the overall number of publications. While this can enhance scientific output, it may also dilute the impact factors of individual journals if the focus shifts from quality to quantity.
  4. Citational Behavior: Changes in the way researchers cite literature can affect impact factors. The increasing use of self-citations and the concentration of citations towards a limited number of highly influential papers can impact the overall citation metrics of journals.
  5. Editorial Practices and Policies: The editorial policies and practices of journals can influence their impact factors. Factors such as rigorous peer review, editorial selectivity, and adherence to ethical publishing standards can attract high-quality submissions and subsequently increase impact factors.
Conclusion: The decline in the impact factors of journals listed in the JCR database can be attributed to a combination of factors related to evolving publication practices, field-specific trends, citational behavior, and editorial practices. Understanding these factors is crucial for researchers, publishers, and other stakeholders to interpret impact factors accurately and make informed decisions regarding journal selection and evaluation.
Further research and analysis are needed to delve deeper into the dynamics of impact factors and explore potential strategies for maintaining the quality and relevance of journals in an evolving scholarly publishing landscape.

In the recently published JCR, the journal Mathematical Biosciences and Engineering does not appear. I have searched everywhere and have found nothing, it does not appear in the list of excluded journals.

Does anyone know anything or can advise where to look?

Relevant answer
Answer
I am afraid they are delisted from Clarivate’s SCIE index.
In the enclosed file you see the journal “Mathematical Biosciences and Engineering” is delisted or more precise it states “Editorial delisting” this means and I quote from the first link “If a journal is removed from coverage because it no longer meets the quality criteria, it will be removed from the Master Journal List and appear as an ‘Editorial De-listing’ in the next Monthly Changes file available from the Monthly Changes Archive.”.
I think it has to do with the suspicious increase in published papers the last two years (as can be seen in for example the “Scpous Content Coverage” here https://www.scopus.com/sourceid/5200152802 ). Most likely this is caused by the excessive use of special issues which has been the cause of a large number of journal titles last year, see for example https://www.researchgate.net/post/Web_of_Science_de-listed_82_journals_Is_it_the_beginning

Fermat and his genius !!!
Below it is rework of the chapter “The Prize” from Simon Singh's book “ Fermat’s Last Theorem: The story of a riddle that confounded the world's greatest minds for 358 years” :
<<Fermat wrote that his proof would not fit into the margin of his copy of Arithmetica, and Wiles’s 100 pages of dense mathematics certainly fulfils this criterion, but surely the Frenchman did not invent modular forms, the Taniyama-Shimura conjecture, Galois Groups and the Kolyvagin-Flach method centuries before anyone else.
If Fermat did not have Wiles’s proof then what did he have?
Mathematicians are divided into two camps:
The sceptics believe that Fermat’s Last Theorem was the result of a rare moment of weakness by the 17th-century genius.
They claim that although Fermat wrote, ”I have discovered a truly marvellous proof”, he had in fact found only a flawed proof.
Other mathematicians, the romantic optimists, believe that Fermat may have had a genuine proof.
Whatever this proof might have been, it would have been based on 17th-century techniques, and would have involved an argument so cunning that it has eluded everybody.
Indeed, there are plenty of mathematicians who believe that they can still achieve fame and glory by discovering Fermat’s original proof.
In my case it is pure passion for the Mathematics and the desire to do justice to Fermat and his genius !!! >>
For this reason I recommend carefully reading the following document entitled "Fundamental elements of a proof” relating to the recently elementary proof of Fermat Last Theorem has been given by Andrea Ossicini.
This articles, entitled "On the Nature of Some Euler's Double Equations Equivalent to Fermat's Last Theorem" effectively provide a reformulation of Fermat's Last Theorem and has been published in 2022 in the journal "Mathematics" by publisher MDPI (Multidisciplinary Digital Publishing Institute).
The Journal "Mathematics" is indexed in SCOPUS. Impact factor 2.4. It is quoted with a journal rank: JCR - Q1 (Mathematics) / CiteScore 3.5 - Q1 (General Mathematics).
Ossicini's article is indicated by Mathematics as "Feature Paper".
This label is used to represent the most advanced investigations which can have a significant impact in the field.
A Feature Paper should be an original contribution that involves several techniques or approaches, provides an outlook for future research directions and describes possible research applications.
Feature papers are submitted upon individual invitation or recommendation by the scientific editors and must receive positive feedback from the reviewer.

Dear Sir/Madam,
I am sending you my article as my friends have suggested. I will now present my friend's speech from the IAEA:
Fermat's Theorem - A Proof by Fermat Himself
(c) Yurkin Pavel, IAEA
The Russian nuclear physicist Grigoriy Leonidovich Dedenko has reconstructed the original reasoning of Pierre Fermat, which led Fermat to conclude that the sum of two identical natural powers of rational numbers, raised to an exponent greater than two, is not representable. This is known as Fermat's Last Theorem.
As you may know, in 1637, Fermat wrote a note in the margins of his copy of Diophantus's "Arithmetic" stating his discovery and adding, "I have discovered a truly marvelous proof, but this margin is too narrow to contain it."
According to G.L. Dedenko, Fermat analyzed power differences using a method that was novel at the time: decomposing these differences into a sum of pairwise products, later known as the "Newton binomial". Fermat discovered that the coefficients in this expansion satisfied simple conditions equivalent to a logarithmic equation (a concept still developing in the mid-17th century) for the degree of the sum (or difference). This equation has only two solutions: the numbers one and two.
Thus, the margins of the book were indeed too narrow to contain the complete proof. Fermat's proof would have required the introduction and development of new concepts, such as expansion with combinatorial coefficients (Newton's binomial) and logarithms. It remains unclear whether Fermat ever wrote down his detailed reasoning, and if so, whether this record survives in an unexpected archive. Historians of natural history are encouraged to search anew.
Sincerely, Grigoriy Dedenko

The journal “Bioinformatics and Biology Insights” is nowadays published by a trusted publisher and therefor you can trust the info stated on their indexing info (https://journals.sagepub.com/metrics/BBI ).
The ‘confusion’ about the impact factor is due to the changed status of an ESCI indexed journal. Since 2023 they receive an impact factor https://clarivate.com/news/clarivate-announces-changes-to-the-2023-journal-citation-reports/ This a well-indexed and good journal.
I see only one disadvantage: the APC is quite high 2650 USD according to
But the answer to your question is yes they an impact factor.

PS. Unfortunately there is no real (publicly available) list of impact factors of ESCI list. Apparently Clarivate managed to protect this (paid) info better than previous years. Although the info is (most of the time) correct I do not trust the BioxBio site, this info is protected property of Clarivate and no contact info can be found about who is behind this site.

Above is the link to the Scopus-source list. But the IF cannot be accessed without Web of Science subscription. One more thing to keep in mind is that not all Scopus-indexed journals have Impact Factor (IF). However, Scopus does provide CiteScore, an IF-like grading system for different journals indexed in the Scopus database. If you search by journal name or ISSN to see whether a particular journal indexed by Scopus is also indexed by WoS, then only you will get its IF.

Stay away from this journal "Migration Letters". I see many issues:
-They were Scopus indexed https://www.scopus.com/sourceid/21000195021 but are now discontinued and the Scopus content coverage stopped somewhere in 2022
-In my reply of Janauary 20th 2024 here https://www.researchgate.net/post/Should_articles_published_in_MDPI_journals_be_excluded_in_the_assessment_of_the_scientific_production_Is_this_already_happening_in_your_country/39I wrote: “…(if you click on Scopus content coverage then you can see that) in 2023 the number of accepted and published papers increased a staggering 15-fold compared to the years before 2023.” This is often a reason for discontinuation
-The publisher seems to be that no longer the reasonably trusted “Transnational Press London” https://www.tplondon.com/about-tpl/ According to https://migrationletters.com/index.php/ml/article/view/2914/2138 the new owner is “Emerging Research Library” and if you scroll down here https://migrationletters.com/index.php/ml/indexthe new ‘publisher’ is called “Migration Letters & The London Publishers”
-The suspicious increase is (in part) explained by publishing completely unrelated papers, like for example the following paper https://migrationletters.com/index.php/ml/article/view/3548 which nothing whatsoever to do with the scope of the journal
I think that either the journal is hijacked or more likely it has been sold and is now managed by people with no other purpose than to collect money as much as possible by exploiting their (no longer existing) Scopus indexing as long as possible.
Personally I would avoid this one. And be sure they are not indexed in Scopus and they don't have an impact factor (since they are not indexed in Clarivate's indexes (ESCI, SCIE or SSCI).

Your observation has to do with the fact that starting in 2023 Clarivate assign an impact factor to journal titles indexed in their ESCI database, see the announcement here https://clarivate.com/news/clarivate-announces-changes-to-the-2023-journal-citation-reports/
While in other years numerous RG members released the latest JCR report (with either only the impact factors or with the quartile Q info as well) it seems that Clarivate effectively prohibited this possibility (since the impact factor info etc. requires a license so payment). All the (incomplete) JCR lists of last year shared here on RG lack (impact factor etc.) info about the ESCI indexed journal titles.
However the good news is that the (claimed) index in ESCI can be checked free of cost here https://mjl.clarivate.com/home If you search for a title (like Scientia Pharmaceutica) and the info confirms the ESCI indexing then you can trust the impact factor info. I never saw examples where the journals lie about this when one visits the websites of journals from serious publishers (like Elsevier, Springer Nature, Wiley and also MDPI) so the impact factor mentioned can be trusted.

Answer
Well first of all the publisher OPAST is mentioned in the Beall’s list (https://beallslist.net ) of potential predatory publishers. This is a red flag and by itself not enough to say they are predatory but there are more red flags:
-The most important is that their indexing info (https://www.opastpublishers.com/international-publisher/indexing-abstracting.html ) is full of so-called misleading metrics (https://beallslist.net/misleading-metrics/ ) such as OAJI and CiteFactor often used by predatory journals/publishers
-Their prominently mentioning of PubMed articles is a misleading practice (again often used by predatory journals/publishers. It is misleading since PubMed index papers where at least one of authors has a NIH grant and this is irrespective of the journal (in other words it says nothing about that particular journal)

How can I calculate the MMAD value after testing dry powder inhaler using next generation impact factor ?
Relevant answer
Answer
The Mass Median Aerodynamic Diameter (MMAD) is an important parameter used to characterize the particle size distribution of aerosolized particles generated by a dry powder inhaler (DPI). To calculate the MMAD for an Aerosol Particle Size Distribution (APSD) test related to a DPI, you can follow these steps:
  1. Collect Data: You will need the APSD data obtained from your DPI testing. This data typically includes the particle size and corresponding mass or number concentration at various size intervals.
  2. Logarithmic Transformation: To calculate the MMAD, you will first need to perform a logarithmic transformation of the particle size data. Take the natural logarithm (ln) of the midpoint of each size interval (usually expressed in micrometers). This will create a new set of values.For example, if your particle size intervals are given as (D1, D2, D3, ...), you will calculate the natural logarithm of the midpoints: (ln(D1), ln(D2), ln(D3), ...).
  3. Weighted Summation: Next, calculate the sum of the products of the logarithmic values and their corresponding mass or number concentrations. The formula for the MMAD is as follows:MMAD = e^(Σ(ln(Di) * Ci) / Σ(Ci))MMAD: Mass Median Aerodynamic Diameter Di: The natural logarithm of the midpoint of each size interval (ln(Di)) Ci: Mass or number concentration corresponding to each size interval In this formula, Σ represents summation, and e is the base of the natural logarithm (approximately 2.71828).
  4. Calculate the Denominator: Calculate the sum of mass or number concentrations (Σ(Ci)) for all size intervals.
  5. Divide: Divide the result from step 3 (the numerator) by the result from step 4 (the denominator) to obtain the MMAD in micrometers.MMAD = e^(Σ(ln(Di) * Ci) / Σ(Ci))
The MMAD represents the median aerodynamic diameter of the particles in the aerosol generated by the DPI. It is the size at which half of the total mass or number of particles is larger, and half is smaller. This information is crucial for assessing the performance and efficacy of dry powder inhalers in delivering medication to the respiratory tract.
It can also be calculated using commercially available software such as CITDAS by Copley Scientific, Nottingham UK
Hope this helps!

Greetings all,
I'd like to ask if 'Oral Oncology Reports' as a companion journal to the well-known 'Oral Oncology' journal would be a good choice to publish?
The journal is a very recent one .. May be only launched in 2022. It was the Editor-in-chief of the 'oral oncology' journal who recommended transferring the manuscript to such new journal. By the way, he is the same Editor-In-Chief!
The journal is indexed in Scopus as written on its website (despite I searched for its name in Scopus & didn't find it!). Of course, no impact factor is present & not listed yet in WOS database.
My question is: Is it wise to publish in such newly borne journal gaining the merit of currently free open access publication offer?
If the manuscript was accepted & published, will it have sufficient credibility later when the journal get known & listed in different reputable databases?
Thanks in advance

Answer
This is an example of a so-called companion journal, see for other examples:
or
Personally, I would say: go for it. As you said yourself you can publish open access for free (they will start to charge a pretty hefty fee for submissions next year). I don’t know if they know more than we do but according to the latest Scopus source list (see enclosed file) the are not listed (yet) and not included in the accepted list. However as indicated in my replies in the above links they most likely will be indexed in Scopus soon (and most likely all papers including the ones published last year and this year).
So, I would say it is OK.
Best regards.

Answer
Dear RG Members
The h-index of researchers and Impact Factor (IF) of journals are fundamentally highly dependent on “The Subject“ in which authors are working and studying papers already published in similar areas and then referring these papers in their proposed research papers to be published as quickly as possible in due course of time.

Can we consider international Society for Research Activity (ISRA), while calculating impact factor or only clarivate is the trusted source for insights and analytics.
Relevant answer
Answer
I suppose that you mean the ISRA JIF. This is an example of a so-called misleading metrics (https://beallslist.net/misleading-metrics/ ).
There are more issues:
-If you look at for example https://ijmer.in/pdf/isra-impact-factor-2021.pdf it is clear that they avoid mentioning of persons
-In the meantime, their website www.israjif.org is no longer functional
So, forget about this one and focus on Clarivate’s impact factor or Scopus CiteScore, see for a bit more info my reply here https://www.researchgate.net/post/How_many_agencies_we_have_for_journal_impact_factor_Can_you_suggest_their_names_according_to_priority

Some journals on Education such as Springer's Discover Education and MDPI's Education Sciences are rather new journals that have yet to attain an impact factor. The question is, would you submit a manuscript to any of these journals or opt to well-established venues such as the IEEE Transactions on Education?
I am raising this question to initiate a discussion. Kindly provide the pros and cons of choosing to submit a manuscript to any of the aforementioned journals.
Relevant answer
Answer
You question the legitimacy of the journal “Discovery Education” (https://link.springer.com/journal/44217 ). I have a number of papers published by Springer and the lay-out changed over the last couple of weeks/months (?), see for example:
If I recall correctly then this lay-out was first used for exclusively open access journal titles published by Springer but it is now for all their titles.
So, SpringerLink is definitely a Springer product and no sign of being predatory.
As you can see at https://link.springer.com/journal/44217 they don’t promise a 7 days turn-over time but an average “First decision” time of 7 days, meaning that the editor will decide to hand-over your manuscript for peer review or decide for desk rejection. I am pretty sure that this journal will get their indexing (Scopus, Clarivate’s ESCI etc.) pretty soon, for now one can benefit of a little launching discount https://link.springer.com/journal/44217/updates/19784724
Best regards.
PS. Their peer review time looks more than reasonable, see for example: https://link.springer.com/article/10.1007/s44217-023-00063-w#article-info Received 01 April 2023, Accepted 08 October 2023 and Published 18 October 2023

https://link.springer.com/article/10.1007/s44217-023-00044-z#article-info Received 01 March 2023, Accepted 02 August 2023, Published 15 August 2023

Journal Impact Factor (JIF) or Impact Factor (IF) of an academic journal is a measure, calculated by the yearly average number of citations to recent articles published in that particular journal. This article explains how to find the impact factor of a journal in detail.
Impact Factor is the more valuable parameter among the academicians, in order to select the journal for publication. It also helps to identify the trustworthiness of the facts given in that journal.
The h-index can be calculated automatically in Web of Science and Scopus or manually in other databases that provide citation information (e.g. SciFinder, PsychINFO, Google Scholar). In this article, we are going to find out, How the journal impact factor and h-index are calculated ?

I can't see the IF of this journal on its web site. I want to ask the research community to give their input in this regard.
Relevant answer
Answer
As you know the “Wireless Communications and Mobile Computing” (https://www.hindawi.com/journals/wcmc/about/ ) is one of the journals delisted by Clarivate from the WoS indexes ESCI, SCIE etc. see for the complete list for example here https://retractionwatch.com/2023/03/21/nearly-20-hindawi-journals-delisted-from-leading-index-amid-concerns-of-papermill-activity/ as indicated here this means and I quote “Removing a journal from Web of Science means Clarivate will no longer index its papers, count their citations, or give the title an impact factor, which can have negative effects for authors, as universities rely on such metrics to judge researchers’ work for tenure and promotion decisions. The company also suppresses journals from its yearly Journal Citation Report that publishes impact factors, as we’ve reported in the past.”
There is more bad news since the journal is also discontinued from Scopus https://www.scopus.com/sourceid/17543 if you click on “Scopus content coverage” it is clear that in 2021 the journal started to accept and publish suspiciously more papers (all caused by the introduction of more special issues).
There is however also some ‘good’ news in this matter:
-If you look at the Scopus source list (see enclosed file) and click on the tab “Discontinued title Sept. 2023” then it is clear that the coverage in Scopus stops here
Art. No. 9898169 (January 21st 2023) Retracted: Text Mining Based on the Lexicon-Constrained Network in the Context of Big Data meaning that your paper is still indexed in Scopus
-Not entirely sure how this will work with the indexing with Clarivate (I have no access to the database since I have no license) but it would not surprise me if it is more or less the same as with Scopus
-Even if the indexing in WoS does not count for your paper I think there is reason for some optimism that the journal will get the impact factor back in a reasonably short time (since the ‘problem’ is identified and the publishing partner Wiley is having a good reputation)
Hope this clarifies the matter somewhat.
Best regards.

Hi,
check the ISSN of the journal in the master journal list (https://mjl.clarivate.com/home) or in the scientific journal ranking (SJR) (https://www.scimagojr.com/journalrank.php) site to see its IF and Q ranking.
If it is a valid journal, you should find its information on these sites.
