I was surfing the web looking for the incoming conferences in computer science, and I finished in this website


Here, it seems that the conferences are ranked as A*, A,B C.

While this is the only place where I have found this rank explicitly, I have heard many other researchers refer to a conference as a "A* conference" or so.

So I am wondering: is this ranking official? Who is maintaining it? And on what is it based?

    This site has few very very questionable rankings, at least for TCS (STACS and FSTTCS are ranked B while FCT, ISAAC, COCOON are ranked A) Every ranking is not official, but tries to capture how each conference is perceived among the peers. Also, acceptance rate does not seem to apply to the ranking

This appears to be a mirror of the CORE conference ranking. It's "official" in the sense that it is (if I remember correctly) maintained by a non-profit sponsored by the Australian government and heavily used in Australia. Everywhere else it's just an opinion point, like every other ranking. My impression is that it's one of the more widely accepted conference rankings, but of course there is still plenty to argue about.

Note that having the "one universally accepted ranking" is impossible to achieve. Different researchers value different things, and a conference that may be modestly interesting to one may be of highest quality to the other. Acceptance rates are also a fairly useless metric of assessing competitiveness, as many middling conferences (at least in my field) get overproportionally many terrible papers, which apparently the authors did not even try submitting to the top conferences.

    Another thing is that to get the scores, they ask Australian researchers for opinions. Thus, they are biased against conferences that are commonly held at places that are harder to reach for Australians (e.g., Europe) - See, e.g., FOSSACS getting a C.

  • ...Also, the ranking from the website listed above is actually quite old - there is a newer CORE ranking.
