Hi all,
I read this again and again and even some of my (former) doctoral student colleagues use it. However, the very little number of persons I had a chance to ask about it obviously did not understand this values by themselves - they just are happy having something more they can use for self-dissemination. So, I ask you all: The impact factor of a single publication, what is this? How is it calculated, when is it calculated and who determines it?
I am well aware of the existence and use /abuse of ranking systems for media, i.e. conference proceedings and particularly, journals. Here, of course an impact factor is used (no need to explain such) in order to show which value a certain media has within a specific community.
But when I look at the impact factor, calculated, e.g., here in ResearchGate (see attachment - also used elsewhere) related to specific publications I additionally recognized something weird: People (and also used this way in the ResearcgGate-System) some-up the various different impact factors from their publications, and claim the sum being ones individual impact factor? Does this have any relevance in the scientific wold (I saw this very first about 2 months ago)? What does a sum of impact factors mean? What makes 500 publications with an impact factor of 0.5 better than a single one with an impact factor of lets say 50 (not sure if there is an upper limit ... I never saw a journal with an impact factor of 6.+ but it seems there are single publications with such one; see attachment, copied from ResearchGate).
As you may realize ... as for me, what I wrote here somehow sounds unstructured and crazy - but this just shows that I completely do not understand what this particular personal impact factor is about. Can someone please explain this to me? I hate the idea missing maybe relevant knowledge ...
Thank you in advance,
yours,
Thomas
