A distributed hypergraph model for the full-scale simulation of the collaborations in dblp
Zheng Xie
This study proposed a model to give a full-scale simulation for the dynamics of the collaborations in the dblp dataset. It is a distributed model with the capability of simulating…
Predicting the number of coauthors for researchers: A learning model
Zheng Xie
Predicting the number of coauthors for researchers contributes to understanding the development of team science. However, it is an elusive task due to diversity in the collaboratio…
Predicting publication productivity for researchers: A latent variable model
Zheng Xie
This study provided a model for the publication dynamics of researchers, which is based on the relationship between the publication productivity of researchers and two covariates:…
Predicting publication productivity for researchers: a piecewise Poisson model
Zheng Xie
Predicting the scientific productivity of researchers is a basic task for academic administrators and funding agencies. This study provided a model for the publication dynamics of…
A game model for the multimodality phenomena of coauthorship networks
Zheng Xie
We provided a game model to simulate the evolution of coauthorship networks, a geometric hypergraph built on a circle. The model expresses kin selection and network reciprocity, tw…
Modelling the Dropout Patterns of MOOC Learners
Zheng Xie
We adopted survival analysis for the viewing durations of massive open online courses. The hazard function of empirical duration data is dominated by a bathtub curve and has the Li…
Profiling MOOCs from viewing perspective
Zheng Xie, Xiao Xiao, Jianping Li +1
We profiled three aspects of MOOCs from the perspective of viewing behaviors, the most prominent and common ones of MOOC learning. They were learner classification, course attracti…
Assessing the level of merging errors for coauthorship data: a Bayesian model
Zheng Xie
Robust analysis of coauthorship networks is based on high quality data. However, ground-truth data are usually unavailable. Empirical data suffer several types of errors, a typical…
Exploring cooperative game mechanisms of scientific coauthorship networks
Zheng Xie, Jianping Li, Miao Li
Scientific coauthorship, generated by collaborations and competitions among researchers, reflects effective organizations of human resources. Researchers, their expected benefits t…
Feature analysis of multidisciplinary scientific collaboration patterns based on PNAS
Zheng Xie, Miao Li, Jianping Li +2
The features of collaboration patterns are often considered to be different from discipline to discipline. Meanwhile, collaborating among disciplines is an obvious feature emerged…
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…
