Comparative analysis of co-authorship networks considering authors' roles in collaboration: Differences between the theoretical and application areas

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
