Scientific Collaboration Network Evolution Model Based on Motif Emerging

Based on the evolvement characteristic of the author collaboration in the scientific thesis, a motif emerging model of the scientific cooperation network is presented. It is validated by the theoretic analysis and computer simulation that the degree distribution of the network nodes is a power law and this network is a scale-free network. In order to make sure the validity of the network model, we gather the articles in Journal of Information Science, and construct a author collaboration network. By analyzing the data of the network, the demonstration results are consistent with that of the model.
