While I am not sure about other fields, Computer science has several conferences an year for multiple of its domain. (there are around 150+ conferences for artificial intelligence alone). Out of all of these conferences, only 15-25 are actually highly regarded and considered as A to A* category.
The other conferences while good, are not really known. They have good proceedings like springer LNCS, ieee explore, etc. They also hold sessions conducted by profs from top schools and people from top private RnD labs. Few even allow the extension of the paper to be accepted into transactions.
Apart from these, there are always the top journals which are SCI indexed.
- Do accepted papers from the non-top conferences add any value to an undergrad CV applying for PhD schools?
Additional motivation for the question:
The alternative to not publishing is keeping it as a pre-print or just a softcopy to link in the CV. But I am told in another question that some form of peer review always adds some weightage. Hence the question.
