Modeling the time-periodicity of in-degree distributions in scientific citation networks
Qi Liu, Zheng Xie, Zonglin Xie +2
In a range of citation networks, the in-degree distributions boast time-periodicity---the distributions of citations per article published each year present similar scale-free tail…
Modeling the coevolution between citations and coauthorships in scientific papers
Zheng Xie, Zonglin Xie, Miao Li +2
Collaborations and citations within scientific research grow simultaneously and interact dynamically. Modelling the coevolution between them helps to study many phenomena that can…
A geometric graph model of citation networks with linearly growing node-increment
Qi Liu, Zheng Xie, Engming Dong +1
Due to the fact that the numbers of annually published papers have witnessed a linear growth in some citation networks, a geometric model is thus proposed to predict some statistic…
Modelling transition phenomena of scientific coauthorship networks
Zheng Xie, Enming Dong, Dongyun Yi +2
In a range of scientific coauthorship networks, transitions emerge in degree distributions, correlations between degrees and local clustering coefficients, etc. The existence of th…
