Abstract: According to the characteristics of collaboration network, local-world and the effect of act degree, this paper proposes a novel Local-World evolving model for Collaboration network(CoLW). The model constructs a local-world hierarchical based on complete graphs, and takes the act in collaboration network as a unit to increase a node. The model can unify the generic properties of real-life collaboration networks, scale-free degree distribution, small average shortest path length and high clustering that is independent of network scale. Experimental results show that the CoLW model can depict the topological structure and statistical characteristics of real-life collaboration networks very well.
