Author Growth Outstrips Publication Growth in Computer Science and Publication Quality Correlates with Collaboration
Although the computer science community successfully harnessed exponential increases in computer performance to drive societal and economic change, the exponential growth in publications is proving harder to accommodate. To gain a deeper understanding of publication growth and inform how the computer science community should handle this growth, we analyzed publication practices from several perspectives: ACM sponsored publications in the ACM Digital Library as a whole: subdisciplines captured by ACM's Special Interest Groups (SIGs); ten top conferences; institutions; four top U.S. departments; authors; faculty; and PhDs between 1990 and 2012. ACM publishes a large fraction of all computer science research. We first summarize how we believe our main findings inform (1) expectations on publication growth, (2) how to distinguish research quality from output quantity; and (3) the evaluation of individual researchers. We then further motivate the study of computer science publication practices and describe our methodology and results in detail.
