Comparative analysis of co-authorship networks of different domains: the growth and change of networks

摘要

There are many studies which try to analyze "co-authorship networks" and to describe their patterns. However, most studies describe mainly static networks, and they do not take into account the statistical peculiarity of author productivity data, i.e., the sample size dependency of statistical measures. In this study, we turn our attention to the change of co-authorship networks according to increase in the sample size. We consider "the dynamic characteristics" of networks, and try to compare co-authorship networks of different domains.
