What does it mean by a "good paper" (in CS) ? - published at a high impact journal/conference ? : There are gazzillions of paper out there in many good journals/conference proceedings but no one really cares about. - total number of citations ? : This may be a factor. But I have seen many survey papers (most of them are boring and mostly involve physical work) get a load of citations, but do not always add anything new. - On the other hand, I have seen a number of good PhD thesis (especially in CS theory/math) that did not produce any "publication", per se. But they are highly cited and pretty much popular. Even many of them are written in Russian/German. The impact of a "research work" is not always possible to be measured by some numbers. Getting the attention of the community is a totally different aspect -- and that's what makes a research work valuable.
