Author cooperation relationship in digital publishing based on social network analysis

The social network analysis method is used to study the author cooperation relationship of the digital publishing. We selected papers from 2005 to 2014 in the CNKI series database. By determining the core authors, drawing the network diagrams and analyzing the density, centrality and clique of the network, we find some results as follows: The situation of the collaboration in all authors is not good; co-authors are basically from the same organization and the same area; each subgroup has its own characteristics. Through this study, we reveal the author cooperation relationship of the digital publishing, thereby promoting the exchange of knowledge.
