Analysing NLP publication patterns - Marek Rei

Recently, I got curious about finding out how much different institutions publish in my area. Does Google publish more than Microsoft? Which university has the strongest publication record in NLP? And are there any interesting trends that can be seen in the recent years? Quantity does not necessarily equal quality, but the number of publications is still a reasonable indicator of general activity in the field, how big the research group is, and how outward-facing are the research projects.
