Rankings of Computer Science conferences and journals I was wondering if there is any kind of "reliable" CS conferences ranking available on the web. I have searched on SCImago, but I believe it only ranks journals, and there is no mention about conferences. Actually I am curious about it because in the faculty that I am currently working we want to know which papers are presented to good conferences, and which ones are presented to bogus conferences.

Is there any way to know that for the field of Computer Science? I know there are some tools like Google Scholar, but I believe it is not so trustable after all. Should we rely on Scopus maybe?

Any advice?
Thanks
There is CORE, an initiative by universities from Australia and New Zealand. On their website, you can find both journal and conference rankings. Most of the rankings are ok, but (of course) there are individual entries that seem too high or too low to me. As far as I know, many research organisations and faculties in the APAC area use this ranking to assign "credit" for papers.

That being said, if your goal is to distinguish good and bogus conferences, I am not sure CORE will actually help you. The main problem is that CORE is only updated every few years, and only with entries which got submitted by somebody during a nomination phase. Hence it is never really complete. Actual bogus conferences (such as the infamous Worldcomp series - see also for instance here) are not listed at all, but so are smaller legit venues as well as any new conference or journal (of any quality). Hence, you can use the presence of a ranking in CORE as a signal that the venue is probably not bogus (it may still subjectively be better or worse than its ranking indicates, but it is very unlikely to be an actual scam), but you cannot use the absence of a ranking to indicate a bogus venue.

Another problem that you may run into is that a few bogus venues have taken up the practice of using a name that is "coincidentally" very similar to existing high-ranked venues (cp. the top-quality WWW conference and the very low-quality WWW/Internet conference). To complicate matters further, in some emerging fields, even more or less established publishers sometimes churn out journals with basically identical names at more or less the same time (e.g., Springer's Journal of Cloud Computing vs Inderscience's Journal of Cloud Computing).

Finally, established conferences occasionally change their name, sometimes as part of a merger with other conferences, and hence "fall of" the ranking if you do not know what the conference used to be called in the past.

All that is to say that CORE is a tool that can help you get a feel for the value of a publication, but it will not relief you from the task of actually looking at the publications themselves to assess their value.
