Hello everyone
I am totally confused between the terms of journals have impact factor, journals have Scopus index number and journals have Thomson Reuters index number. Could anyone explain for me when we should use these terms?
Thanks

If both company calculate the quality of a journal, thus, it makes easier for you to choose the best to publish. However, scientifically, what's important is the scope of the journal and time taken to process and publish a manuscript and the cost of publishing.
Good answers. In addition, the Thomson Reuters become now Clarivate analytics
Hi,
The Thomson Reuters changed its name into Claryvate Analytics, and it is a journal articles database. It indexes papers from many journals that passed a threshold of citations, and several other quality criteria. The Impact factor is an indicator, created by this database to rank journals according to quality (relation of citations to publications). Scopus is another journals' indexing database, created by the publisher Elsevier, and it also created an impact factor, calculated differently. Calryvate Analytics is considered a more selective database than Scopus. The inclusion rate of Scopus is higher than in Claryvate.
You can find the latest thomson reuters journal impact factor list that is published in june 2018 in the following:

The Thomson Reuters is a journal indexing and articles database. It indexes papers from many journals that passed a threshold of citations and several other quality criteria. Scopus is another journals' indexing database, created by the publisher Elsevier. In academia, Thomson Reuter is not recommended and not acceptable. It has a lower quality than Scopus.
But, The impact factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. It is used to measure the importance or rank of a journal by calculating the times its articles are cited. The calculation is based on a two-year period and involves dividing the number of times articles were cited by the number of articles that are citable.
Calculation of 2020 IF of a journal:
A = the number of times articles published in 2018 and 2019 were cited by indexed journals during 2020.
B = the total number of "citable items" published in 2018 and 2019.
A/B = 2020 impact factor

Dear Demsew Teferra ,
Not entirely sure what you mean with your statement “Thomson Reuter is not recommended and not acceptable”. Since it is as such not true. As indicated by Avishag Gordon Thomson Reuter does not exists anymore. All relevant databases (ESCI, SCIE and SSCI) are now owned by Clarivate. Even stronger Clarivate is the only one that assigned impact factors to journals (once indexed in SCIE or SSCI). Scopus is having their own ‘impact factor’ called CiteScore.
If you mean that in certain parts of the world Scopus is more appreciated than WoS (or Clarivate’s impact factor) then you are right. In the following paper:
Preprint Prevalence of Potentially Predatory Publishing in Scopus on ...
One can find an interesting figure (Fig. 2) that roughly shows the preferences when it comes to Scopus or WoS (Clarivate).
Personally, I prefer a journal with a real impact factor since Scopus is having issues with indexing predatory journals and seem to have troubles in detecting the so-called hijacked journals (or at least take too much time to act upon them). See for example:

Best regards.
The Thomson Reuters is an articles database, while impact factor is the score of citation of certain journal.
Hi,
The impact factor is a measure of citations and publications of journals, and it was designed by the producers of the World of Science databases, that was called once Thomson Reuter, and it is called now Clarivate Analytics.
