Methodology for Analyzing Thematic Co-Authorship Networks

Anthony Nwohiri, Andrey A. Pechnikov

Abstract


An interesting feature that networks present is the community structure property, under which a graph topology is organized into modules called communities. This paper proposes a co-authorship graph-based methodology for studying thematic communities. The graph is divided into thematic communities to identify their basic characteristics, such as research thematic direction, researcher count, community count and relationship between researchers. This information could be used to make incentives policies that would support pertinent research areas. The proposed methodology was tested using data retrieved from mathematical portal Math-Net.Ru. The findings of the tests indicate that more research in robots and robotic systems, combustion/explosion, and data protection techniques/systems need to be promoted. It was demonstrated that the mathematical models employed were adequate and applicable to different research domains. However, this would need complete and reliable basic bibliographic data on research co-authorship within the relevant discipline over a long enough period.
