FAQs about Scientific Research

  • How can I tell if a certain journal is listed in the Clarivate Analytics database?

Please visit: http://mjl.clarivate.com/, In the search slot, write the journal name or the ISSN. If the journal is listed, press "coverage" to know the exact classification of the journal.

  • What is the difference between the Scopus and Clarivate Analytics databases?
  • Is it possible to find a journal listed in Clarivate Analytics database but not listed in Scopus?

Yes, this depends on whether the journal applied to the database. For example, as of January 2019, "Journal of Taibah University for Sciences" is listed in Clarivate Analytics under "Science citation index expanded", but it is not listed in Scopus.

  • How is the impact factor of a journal computed?

Simply, to compute the impact factor for a journal in a certain year (A), use the following formula: IF= (C(A-2)+C(A-1))/(N(A-2)+N(A-1))

C(X) stands for the number of citations that journal has received in year X and N(X) is the total number of papers published in that journal in the year X. For more details, please visit: https://en.wikipedia.org/wiki/Impact_factor

  • What is the H-index?

  • Does the impact factor reflect the real quality of the journal?

Definitely not; there are scientific journals with a low impact factor, but their quality is much higher than journals with a high impact factor. In fact, the value of the journal's impact factor depends on several aspects, including:
1. The impact factor will increase if the journal publishes research works for free.
2. If the subject of the journal or research is easier than others, it is expected to have a larger number of researchers in this field, and the impact factor will increase.
3. The impact factor is also expected to increase based on the importance of a certain topic at a specific period of time.

  • Do world leading universities consider the impact factor in their evaluation of scientific research?

Not necessarily; evaluating scientific research in the prestigious universities depends on the actual quality of research. While for the journals, the impact factor is not the most important aspect, but rather the academic reputation.

  • How do leading researchers select their journals?

Leading researchers select their journals based on the journal's reputation in the research community, in addition to the high impact factor. If the researchers were given the choice, the decisive factor would be the journal's true reputation in academia.

However, thanks to the increasing number of journals and researchers, and the emergence of some journals whose purpose is financial gain, some universities, unfortunately, have opted to distinguish the level of research by the impact factor of the journal.

  • What is "Emerging Sources Citation Index"?

From Wiki: The Emerging Sources Citation Index is a citation index produced since 2015 by Thomson Reuters, and now by Clarivate Analytics. According to the publisher, the index includes "peer-reviewed publications of regional importance and in emerging scientific fields".[1] It has been observed that among the databases produced by Clarivate Analytics, the Emerging Sources Citation Index is the easiest one to get into and that as a result it contains many predatory journals.

  • What is a "predatory journal"?

  • Can a predatory journal be indexed?

The following paragraph is taken from: https://www.researchgate.net/post/Scopus_vs_Clarivate_Analytics_journals, It is rare for predatory journals to be indexed by lists such Scopus but it does happen. For some examples, see Working Paper: Do not feed the predators (or for information on the published version, see Article: Do not feed the predators). This being said, it is more common for predatory journals to lie about being indexed by such lists or, as Kay Smarsly says, to be indexed by fake indexed factors (for examples of such fake indexed factors, see https://beallslist.weebly.com/misleading-metrics.html).
