a research topic bursts in terms of NSF
grants first, it is likely to burst in publications within a few years. The opposite
pattern is at least twice less frequent.
Hence, we conclude while funding is
not necessary in the initial growth in
a CS research topic, it is essential for
maintaining research momentum and
Most authors manage to publish at
most once a year in a particular research
field. Moreover, authors tend to publish
in the same major research category
for at most only a few years. Only a fraction of them continues to publish in the
same field year after year for a long time.
This agrees well with the model of an
academic research team in which permanent faculty represent only a small
fraction of the overall team of faculty,
students, and postdocs, with the latter
routinely changing topics after leaving
a team. Moreover, a faculty member is
often active in more than one area. Finally, since novelty is prized, authors
tend to pursue new directions in their
research, as reflected in an article’s abstract and keywords, further contributing to the observed pattern.
