By publishing papers together, academic authors can form a co-authorship network, modeling the collaboration among them. This paper presents a data-driven study by crawling and analyzing the vast majority of author profiles of Google Scholar. We make the following major contributions: (1) We present a demographic analysis and get an informative overview of the authors from different aspects, su...

We analyze the strength of ties through three different clustering algorithms applied to co-authorship social networks from three different research areas. This study reveals if tie strength metrics can be used to evaluate clusters quality. We obtain different results for each algorithm and observe that Markov cluster algorithm provides the best results for co-authorship social networks. Also, ...
